Your game is ready. The trailer looks great. The screenshots pop. But then you stare at the Steam store page editor, cursor blinking in the description field, and realize you have no idea how to sell your own game in words.
You’re not alone. Writing compelling Steam descriptions is genuinely hard. You need to hook players in seconds, explain what makes your game special, and convince them to click that wishlist button. Most developers are builders, not copywriters. The blank page feels impossible.
Here’s what changed: AI tools for Steam descriptions actually work now. Not generic marketing fluff. Real, conversion-focused store page copy that understands what makes players click. I’ve tested every major option and compiled the best AI tools for writing game descriptions, complete with actual prompts you can use today.
Why Your Steam Store Description Matters More Than You Think
Before diving into tools, let’s talk about why this matters so much.
Steam shows your short description everywhere. Search results. Discovery Queue. Recommendations. Wishlists. That single paragraph is often the only text players read before deciding whether to investigate further or scroll past.
The “About This Game” section does the heavy lifting for interested visitors. It needs to communicate genre, gameplay, story hook, and key features while maintaining a tone that matches your game’s personality. A horror game needs different energy than a cozy farming sim.
Bad descriptions actively hurt conversions. Walls of text get skipped. Generic marketing speak triggers skepticism. Typos and awkward phrasing signal amateur quality. Players unconsciously judge your game’s polish by your store page writing.
The good news: AI copywriting tools for game marketing have become remarkably effective at generating Steam-ready content. They understand hooks, formatting, and the specific language that converts browsers into wishlists.
How to Write Steam Store Page with AI: The Basic Framework
Before choosing a tool, understand what you’re generating. Steam store pages have two distinct text sections with different requirements.
The Short Description
This is your one-paragraph elevator pitch. No formatting allowed. Plain text only. Steam limits this to roughly 300 characters, so every word must earn its place.
The short description appears in search results, recommendations, and anywhere Steam displays your game thumbnail. It’s the most-read text on your entire store page. Most players never scroll further.
Effective short descriptions follow a pattern: genre context plus unique hook plus emotional promise. “A roguelike deckbuilder where your cards are living creatures that evolve, mutate, and remember how you’ve treated them” tells players exactly what to expect while hinting at something they haven’t seen before.
The About This Game Section
This is your long-form pitch. Steam supports formatting here: bold headers, bullet points, italics, and links. The section can run several paragraphs with feature lists.
Structure matters. Players scan rather than read. Bold headers break up text into digestible sections. Bullet points highlight features quickly. The opening paragraph needs to hook immediately because many players won’t scroll past it.
AI tools handle both sections, but you’ll prompt them differently. Short descriptions need punchy, dense output. Long descriptions need structured, scannable content with clear formatting.
Best AI Tools for Writing Steam Game Descriptions
After testing every major platform, these tools emerged as the most effective for Steam store page copy.
ChatGPT: Best Overall for Steam Page Copy
For most indie developers, ChatGPT (GPT-4 or GPT-4o) offers the best combination of quality, flexibility, and value for writing Steam game descriptions with AI.
How to Use ChatGPT: for Indie Game Development: The Complete Guide for Solo Developers
The conversational interface means you can iterate naturally. Generate a draft, then ask for revisions: “make it punchier,” “add more mystery,” “remove the marketing speak.” ChatGPT adjusts on the fly without requiring new prompts from scratch.
One Reddit gamedev demonstrated this beautifully. They asked ChatGPT to make their description “more humorous” and received: “Hellfight is a platformer that’s all about kicking butt and taking names… if a roguelike and a soul-like had a baby, and that baby was a total combat maniac.” A follow-up request for “clean and clear” produced a concise, professional alternative. Same tool, completely different tones, seconds apart.
ChatGPT handles genre-specific prompts exceptionally well. Horror games, cozy sims, hardcore roguelikes, narrative adventures. Specify your genre and the AI adapts vocabulary, sentence structure, and emotional tone accordingly.
The limitation: ChatGPT doesn’t include built-in SEO optimization or Steam-specific templates. You’re working with raw AI capability, which rewards good prompting but requires more effort than template-based tools.
Pricing: Free for GPT-3.5. $20/month for GPT-4 via ChatGPT Plus.
Best for: Any developer who wants maximum flexibility and is willing to craft specific prompts.
Claude: Best for Long-Form Descriptions
Anthropic’s Claude excels at longer, more nuanced content. If your game has complex lore, multiple systems to explain, or needs a detailed “About This Game” section, Claude handles extended writing better than most alternatives.
Claude produces coherent multi-paragraph descriptions that maintain consistent tone throughout. Where other AI tools sometimes drift or repeat themselves in longer outputs, Claude stays focused.
Professional AI writers have noted using Claude specifically for longer-form game content while switching to ChatGPT for punchier taglines. The tools complement each other.
Claude’s free tier works well for description generation. The interface is clean and conversation history helps when iterating on drafts.
Pricing: Free tier available. Paid plans for extended usage.
Best for: Games with complex narratives, multiple features to explain, or developers who need comprehensive “About This Game” sections.
Google Gemini: Best for Direct, Conversion-Focused Copy
In head-to-head comparisons, Gemini produces noticeably different output than ChatGPT. Where ChatGPT tends toward creative, emotional language, Gemini favors clarity and directness.
For Steam descriptions, this can be advantageous. Gemini’s output includes stronger calls-to-action and benefit-focused language. The copy feels more like professional marketing material and less like creative writing.
If your game targets audiences who prefer straightforward communication (simulation players, strategy enthusiasts, puzzle game fans), Gemini’s style may convert better than flowery alternatives.
Pricing: Free tier available. Gemini Advanced around $20/month.
Best for: Developers wanting crisp, professional, no-nonsense store page copy.
Jasper.ai: Best for Brand-Consistent Marketing
Jasper is a premium marketing AI with features specifically designed for brand consistency. The platform offers 50+ copywriting templates, including product descriptions and marketing copy that translate well to Steam pages.
The standout feature for game developers is Brand Voice. Set up your game’s tone, terminology, and style preferences once. Jasper then applies those guidelines to every piece of content it generates. If your game has a specific personality you need to maintain across all marketing materials, this consistency matters.
Jasper also includes built-in SEO tools, useful if you’re creating a landing page alongside your Steam page.
The trade-off is cost. Jasper’s pricing (starting around $29/month, scaling to $109+ for advanced features) targets marketing teams rather than solo developers. For studios or developers with marketing budgets, the investment pays off in time saved and consistency gained.
Pricing: From approximately $29 to $109+ per month depending on tier.
Best for: Studios, marketing teams, and developers who need consistent brand voice across multiple properties.
Copy.ai: Best for Generating Multiple Variants
Copy.ai specializes in generating multiple output variations quickly. Request a product description and receive 10+ different versions to choose from. This approach works exceptionally well for Steam descriptions where you might want to A/B test different hooks.
The tone selector lets you toggle between “fun,” “professional,” “witty,” and other presets with one click. Generate a serious description, then click a button for a humorous version. Compare and combine elements from different outputs.
Copy.ai also supports multilingual generation natively, valuable for developers localizing their Steam pages.
The platform doesn’t include built-in SEO optimization, so it’s more about creative copywriting than keyword strategy. For Steam pages specifically, this is usually fine since discoverability comes primarily from tags and Steam’s algorithm rather than text-based SEO.
Pricing: Free trial available. Paid plans from approximately $49/month.
Best for: Developers who want to compare multiple description variants quickly.
Rytr: Best Budget Option
For solo developers and hobbyists on tight budgets, Rytr offers genuine value. The platform provides 30+ writing use cases in a simple document-style editor.
Rytr’s free plan includes 10,000 characters monthly. That’s enough to generate and iterate on several Steam descriptions without paying anything. The paid tier ($29/month or ~$290/year) removes limits while remaining affordable compared to premium alternatives.
Output quality is solid though not exceptional. Rytr works well for first drafts that you’ll refine manually. The Chrome extension lets you write directly in Steam’s text fields if you prefer working in-browser.
Pricing: Free tier with 10,000 character monthly limit. Paid from $29/month.
Best for: Solo developers, hobbyists, and anyone needing a low-cost starting point.
Writesonic: Best for SEO-Optimized Content
Writesonic combines AI writing with built-in SEO tools. The Product Description Generator creates copy while the SEO checker optimizes for keyword inclusion.
For developers creating landing pages alongside their Steam presence, Writesonic’s SEO capabilities add value. The platform can integrate with SurferSEO for content briefs if you’re serious about organic search traffic.
For Steam pages specifically, Writesonic’s SEO features matter less (Steam discoverability works differently), but the writing quality is strong and the tool versatility (ads, landing pages, social content) might justify the subscription if you’re handling all your game’s marketing.
Pricing: Free limited credits. Paid plans from approximately $20 to $99/month.
Best for: Developers managing complete marketing campaigns including landing pages and ads alongside Steam content.
AppyPie Game Description Generator: Best for Quick Steam Formatting
AppyPie offers a game-specific description generator with a notable feature: Copy HTML output. Since Steam’s long description supports formatted text, this direct export saves manual formatting work.
The tool is simpler than full AI writing platforms but solves a specific workflow problem. Generate, copy the HTML, paste into Steam’s editor. Done.
Pricing: Free to use with limitations.
Best for: Developers wanting the fastest path from generation to Steam page.
ChatGPT Steam Page Copy Prompt: Templates That Actually Work
Generic prompts produce generic descriptions. These specific templates generate Steam-ready copy.
Short Description Prompt
Write a Steam short description (under 300 characters, no formatting) for my game:
Genre: [Your genre, e.g., "roguelike deckbuilder"]
Unique hook: [What makes it different, e.g., "cards are living creatures that evolve based on your choices"]
Target audience: [Who plays this, e.g., "fans of Slay the Spire who want more attachment to their deck"]
Tone: [Desired feeling, e.g., "mysterious but inviting"]
Make it immediately communicate what the game IS and why it's different. Hook in first 5 words.
About This Game Prompt
Write a Steam "About This Game" section for my game with this structure:
Opening hook paragraph (2-3 sentences that grab attention and establish genre/mood)
**Key Features** section with 5-6 bullet points highlighting unique gameplay elements
**Story Setup** section (2-3 sentences establishing premise without spoilers)
**What Players Say** section (even if fictional/anticipated reactions, helps establish appeal)
Game details:
- Title: [Your game title]
- Genre: [Primary and secondary genres]
- Core gameplay loop: [What players actually DO moment-to-moment]
- Unique mechanics: [What's different about your game]
- Aesthetic/vibe: [Visual style, audio feel, emotional tone]
- Similar games for reference: [Games your audience likely enjoys]
Tone: [Match your game's personality]
Format for Steam (use **bold** for headers, bullet points for lists)
Tone Adjustment Prompts
After generating initial copy, use these follow-ups:
For more personality: “Rewrite this with more character. Add subtle humor and make it feel like the game has personality, not just features.”
For more clarity: “Simplify this. Remove any marketing jargon. Make it immediately clear what the player actually does in this game.”
For more urgency: “Add more emotional hooks. Make players feel like they’ll miss something special if they don’t wishlist.”
For genre-specific tone: “Rewrite this in the voice of [specific game or developer known for good writing]. Match their energy.”
Best Prompts for Writing Steam Game Description: Advanced Techniques
The Comparison Frame: “Write this description assuming players are comparing it to [similar popular game]. Acknowledge what they already know about the genre, then emphasize what’s different.”
The Reviewer Quote Approach: “Write this as if summarizing glowing reviews. What would critics say about why this game works?”
The Player Experience Focus: “Focus entirely on how it FEELS to play, not what features exist. Describe the emotional journey of a play session.”
AI-Generated Steam Store Blurb Examples
Seeing actual output helps calibrate expectations. Here are examples generated using the prompts above.
Example 1: Roguelike Deckbuilder (ChatGPT)
Short Description: “Build a deck of living cards that remember everything. Every battle shapes their evolution. Every sacrifice haunts you. A roguelike deckbuilder where your choices echo through every run.”
Opening of About This Game: “Your cards aren’t tools. They’re companions. They learn. They grow. They remember when you fed them to stronger cards for a power boost.
Nightbound is a roguelike deckbuilder where every card in your deck is a living creature with memory, personality, and grudges. Victories teach them new abilities. Losses traumatize them. And sacrificing one card to empower another? The survivors notice.”
Example 2: Cozy Farming Sim (Claude)
Short Description: “Inherit a lighthouse. Befriend the local spirits. Grow impossible plants under moonlight. A gentle farming sim about finding magic in the margins of the world.”
Opening of About This Game: “The lighthouse keeper vanished years ago, leaving behind a garden of luminescent flowers and a cat who definitely understands more than it lets on.
Tidal Harvest invites you to restore a forgotten coastal sanctuary where the mundane and magical blur together. Tend crops that bloom only at certain moon phases. Trade stories with spirits who remember the old lighthouse keeper. Discover why they left, and whether you’ll stay.”
Example 3: Action Roguelike (Gemini)
Short Description: “90 seconds per run. One weapon. Infinite skill ceiling. Master the blade in this ultra-precise action roguelike where every death makes you deadlier.”
Opening of About This Game: “Each run is 90 seconds. Each run is winnable. Each run will kill you until you’re good enough.
Bladetick strips the roguelike to its core: pure skill expression in compressed time. No upgrades between runs. No progression systems. Just you, your blade, and rooms designed to be beaten perfectly. Every death is a lesson. Every victory is earned.”
How to Optimize Steam Game Page with AI: Beyond Descriptions
AI tools for Steam page content extend beyond the main description. Here’s how to leverage them for complete store page optimization.
Tag Research
Ask ChatGPT or Claude: “What Steam tags best describe a [your genre] game with [your unique elements]? List 15-20 relevant tags in order of importance for discoverability.”
Then cross-reference with actual Steam tag data to verify which tags have good discoverability without overwhelming competition.
Capsule Image Text
If you’re adding text to capsule images: “Write 3-5 word taglines for a [genre] game capsule image. Each should be immediately readable and convey [core appeal]. Give me 10 options.”
Early Access Messaging
“Write an Early Access description explaining what’s currently in the build, what’s planned, and why players should join now. Be honest about the state while generating excitement.”
Update Announcement Templates
“Create a template for Steam update announcements that includes: hook headline, what’s new (features/fixes), what’s next (roadmap preview), and community thanks. Tone: [your game’s voice].”
Free AI Tools for Indie Game Descriptions
Budget constraints are real. These options cost nothing.
ChatGPT Free (GPT-3.5): Solid quality for description generation. Lacks the nuance of GPT-4 but handles Steam copy competently.
Claude Free Tier: Excellent for longer descriptions. Usage limits apply but sufficient for store page work.
Gemini Free: Strong alternative with different writing style than ChatGPT. Worth testing to see which output you prefer.
Rytr Free Tier: 10,000 characters monthly. Enough for multiple description drafts.
AppyPie Generator: Free game description tool with HTML export.
The free tier strategy: Generate initial drafts with free tools. If you find yourself limited by quality or usage caps, upgrade to a $20/month ChatGPT Plus subscription. That’s less than the cost of a single hour with a freelance copywriter.
Common Mistakes When Using AI for Steam Descriptions
AI tools accelerate writing but introduce specific failure modes. Avoid these.
Accepting First Drafts
AI output improves dramatically with iteration. Never publish the first generation. Ask for rewrites, tone adjustments, and alternatives. Then edit manually on top of the AI output.
Generic Marketing Language
AI defaults to safe, generic copy. Phrases like “immersive experience,” “engaging gameplay,” and “stunning visuals” mean nothing. Always prompt for specificity: “What exactly does the player DO that’s fun?”
Ignoring Steam Formatting
The short description allows no formatting. The long description supports it. AI doesn’t always remember these constraints. Verify formatting matches Steam’s requirements before pasting.
Overpromising
AI writes confident marketing copy. It might describe features your game doesn’t have or overstate what’s included. Read every line critically. Players will review-bomb games that don’t match descriptions.
Forgetting Your Voice
Generic prompts produce generic output. Include your game’s specific personality in every prompt. “Write this like the game itself is talking” produces very different results than “write a product description.”
Steam’s AI Disclosure Requirements
As of recent updates, Steam requires developers to disclose AI-generated content within their games. While this primarily targets in-game AI usage (like AI-generated art or voices), transparency principles extend to marketing.
If you use AI to generate your store description, you’re not currently required to disclose this specifically. However, Steam’s policies evolve, and best practice suggests keeping records of what AI tools you used for what content.
The descriptions themselves remain your responsibility. AI generates drafts; you’re accountable for what you publish.
The Hybrid Workflow That Actually Works
After testing every approach, here’s the workflow that produces the best Steam descriptions:
Step 1: Generate with AI. Use ChatGPT or Claude to create initial drafts. Generate 3-5 variants of both short and long descriptions.
Step 2: Identify strongest elements. Read all variants. Note the hooks, phrases, and structural choices that work best. Often the perfect description combines elements from multiple generations.
Step 3: Manual editing pass. Combine the best elements. Adjust tone to match your game’s actual personality. Remove anything that feels generic or overpromised.
Step 4: Specificity check. Read your description as if you’ve never seen your game. Does it communicate what players actually DO? Can someone picture the gameplay? If not, revise until they can.
Step 5: Format and verify. Ensure short description fits character limits. Verify long description formatting works in Steam’s preview. Check that no AI hallucinations slipped through (made-up features, incorrect genre claims).
Step 6: Test with humans. Show the description to someone unfamiliar with your game. Ask them to describe what they think the game is. Their answer reveals whether your copy communicates effectively.
Tool Recommendations by Situation
Solo Developer, Zero Budget
Start with ChatGPT free tier (GPT-3.5). Generate multiple variants. Edit heavily. Upgrade to ChatGPT Plus ($20/month) only if quality limitations block you.
Solo Developer, Some Budget
ChatGPT Plus ($20/month) provides the best quality-to-cost ratio. GPT-4 handles nuanced prompts significantly better than 3.5.
Small Studio, Marketing Budget
Jasper ($29-109/month) for brand consistency across all marketing materials, or Copy.ai ($49/month) for variant generation when A/B testing descriptions.
Need SEO for Landing Page
Writesonic with SEO features for combined Steam page and website content.
Complex Narrative Game
Claude for coherent long-form descriptions that maintain tone across extended copy.
Quick Draft, Minimal Effort
Rytr free tier or AppyPie for functional descriptions in minutes.
The Bottom Line
AI tools for Steam descriptions have matured from novelty to essential workflow. The right tool depends on your budget, the complexity of your game, and how much manual editing you’re willing to do.
For most indie developers, ChatGPT Plus at $20/month offers the best balance of quality, flexibility, and value. Use the specific prompts in this guide rather than generic requests. Iterate on outputs rather than accepting first drafts. Edit every AI generation before publishing.
Your Steam description is often the only text players read before deciding on your game. AI tools make good descriptions accessible to developers who aren’t natural copywriters. But the tools generate drafts, not finished copy. The final polish, the specific details that make your game unique, the authentic voice that matches your creation—those still require your judgment.
Generate smart. Edit carefully. Convert browsers into wishlists.
Your game deserves a description as good as the game itself. Now you have the tools to write one.
