I built a tool that scans HN/StackExchange for unmet needs before you build anything — would love feedback

A few months ago I kept seeing the same advice everywhere: "validate before you build." But actually doing that manually — scrolling through Reddit threads and Hacker News comments looking for recurring complaints — takes forever. So I built Griper. It scans places like Hacker News and Software Recommendations Stack Exchange, scores posts by how much genuine pain/frustration they express, and shows you which problems keep coming up unsolved (plus what existing tools people already tried and

AI 分析

痛点:独立开发者在动手写代码前做需求验证时,只能人工翻遍 Reddit、Hacker News、StackExchange 找重复出现的抱怨,耗时且容易漏掉真正未被解决的问题。

目标用户:准备启动新项目的独立开发者、早期创业者、做 niche 选品的副业开发者

证据:actually doing that manually — scrolling through Reddit threads and Hacker News comments looking for recurring complaints — takes forever. / Trying to understand if this solves a real workflow problem or just my own.

变现:订阅制 SaaS(按月/年),按可扫描的细分领域数或生成的痛点报告数量分档收费;也可提供单份垂直行业痛点报告的付费下载作为低门槛入口。

MVP:2 周内用 HN Algolia API + StackExchange API 抓取帖子,做关键词聚类与「抱怨/求替代品」情绪打分,输出每周精选的 Top 10 未满足需求报告,接 Lemon Squeezy/Stripe 做 $9-19/月的订阅,先在 SideProject/IndieHackers 社区卖验证。

竞品:GummySearch、IdeaPicker、PainRadar、Exploding Topics

摘要:一位独立开发者做了 Griper,抓取 Hacker News 和 Software Recommendations Stack Exchange,按「痛苦程度」给帖子打分,帮人在投入数月前找出反复出现且未被解决的问题,并展示用户试过又放弃的工具。帖子本身没有任何付费意愿原话或收入数据,作者自己也承认不确定这是真实工作流痛点还是只是自己的需求。需求方向成立(idea validation 确实耗时),但同类工具已不少,竞争空间有限。
