I built a Windows app that auto-captures on-screen pages and OCRs them into one searchable PDF

Solo dev here. I kept running into the same annoying problem: stuff I could see on my screen but couldn't actually search or select — course viewers, ebook readers, slide decks, scanned docs locked inside some app. You can read it, but you can't Ctrl-F it. So I built CapDrop (Windows). The idea is dead simple: you set a capture interval, hit start, and walk away. It screenshots each page, advances, runs OCR locally, and hands you back one searchable PDF at the end. No stitching 40 screensho

AI 分析

痛点:屏幕上的内容(课程播放器、电子书阅读器、幻灯片、扫描文档)无法搜索或复制,只能手动截图再拼接。

目标用户:需要处理无法复制/搜索屏幕内容的学生、研究人员、法务、财务、知识工作者、Windows 用户。

证据:stuff I could see on my screen but couldn't actually search or select — course viewers, ebook readers, slide decks, scanned docs locked inside some app. You can read it, but you can't Ctrl-F it. ... One-time price, not a subscription. $19 once. There's a 7-day trial, and the free tier still makes an image-only PDF if you just want that.

变现:一次性买断授权($19),提供免费图片PDF版和7天试用,可增加高级版(批量处理、更高OCR精度、自动翻页规则)或企业授权。

MVP:2周内用Electron/Tauri做Windows小工具:设置截图间隔 + 自动发送翻页/滚动按键 + 本地Tesseract/PaddleOCR + 合并为可搜索PDF,先只支持一种场景(如在线课程播放器)。

竞品:TextSniper、Snagit、OCRmyPDF、Microsoft PowerToys Text Extractor、Capture2Text、Adobe Acrobat OCR

摘要:一个独立开发者发布了Windows应用CapDrop,可定时截屏并本地OCR成可搜索PDF,解决屏幕内容无法Ctrl-F的问题。定价$19一次性买断,有7天试用和免费图片PDF版。帖子展示清晰痛点与变现方式,但未提供实际收入或用户付费反馈,需求验证仍偏弱。
