I built an AI grader for Steam capsule art — 2 strangers paid for it before I ever marketed it

I just launched a side project that might interest other devs here: an AI tool that grades Steam capsule art. The problem: your capsule art has about half a second to earn a wishlist on Steam, and most indie games fail before anyone reads the description. When I was prepping my own game's Steam page, I went through a dozen capsule versions with no idea which one was actually good. Friends' feedback was polite and useless. So I built CapsuleGrader. Upload your capsule, pick your genre, and

AI 分析

痛点:独立游戏开发者在 Steam 上架前无法客观判断自己的胶囊图(capsule art)好坏,朋友反馈客套无用,而胶囊图只有半秒时间决定玩家是否加愿望单。

目标用户:准备或已上线 Steam 页面的独立游戏开发者(尤其个人开发者和小团队)

证据:two people subscribed before I did any marketing at all, which is why I'm posting this — turns out capsule art anxiety is a whole market. / Friends' feedback was polite and useless. / I went through a dozen capsule versions with no idea which one was actually good.

变现:免费 3 次分析引流 + 订阅制(按月/按次付费包),可加高价人工专家点评或 A/B 测试报告作为增值层

MVP:2 周内可做:上传图片 + 选择品类 → 用视觉 LLM 输出 100 分制评分、10 项检查清单(焦点、对比度、品类信号、缩略图可读性)、Steam 列表尺寸缩略图模拟、带真实 Steam 优秀案例的优先修改建议;免费 3 次后接 Stripe 订阅。

竞品:Chris Zukowski / How To Market A Game 的胶囊图点评、GameDiscoverCo 相关咨询服务、Steam 官方胶囊图规范文档、通用 AI 图像分析/设计反馈工具

摘要:一位开发者在 r/SideProject 发布 CapsuleGrader,用 AI 给 Steam 胶囊图打分(100 分制 + 10 项检查清单 + 缩略图存活测试 + 15 个品类的对标基准),10 秒出结果,免费 3 次无需注册。上线后完全没做营销就有 2 人付费订阅,作者据此判断“胶囊图焦虑是一个真实市场”。需求真实但规模尚小,适合独立开发者用视觉大模型快速复刻。
