I got tired of every free online scanner wanting my ID on their server, so I built one that runs in the browser

AI 分析

痛点:人们需要把证件/表格照片做成符合大小要求的 PDF,但现有免费在线转换工具要求上传敏感文件,护照、身份证等隐私文件被迫存放在陌生服务器上。

目标用户:需要提交扫描件(签证、学校申请、银行开户)但对隐私敏感的普通用户、留学生、跨境办事人群

证据:Every form I deal with asks for "a scanned copy, PDF, under 200 KB". Visa portals, university applications, the bank. ... Which means their passport or ID card now sits on a server they know nothing about. ... The part I'm least sure about is trust.

变现:Freemium:浏览器内扫描与 PDF 导出免费,OCR 文本提取、批量处理、精确目标大小压缩、多页合并、离线 PWA/桌面版作为付费点;或采用一次性买断/订阅(如 3-5 美元/月);亦可做可审计的"零上传"合规版面向企业/机构。

MVP:用 WebAssembly 版的 OpenCV.js + Tesseract.js 做浏览器内边缘检测、透视校正、白纸增强与 PDF 导出,加一个离线可用的 Service Worker 与"网络请求可视化"面板来建立信任;2 周内可上线 OCR(付费)与目标文件大小压缩两个付费钩子。

竞品:Adobe Scan、CamScanner、Genius Scan、iOS/Android 系统自带扫描、各类免费在线 PDF 转换站(如 iLovePDF、Smallpdf)

摘要:开发者在 r/SideProject 发布 LensUp,一个完全在浏览器内运行的文档扫描工具,照片不出设备即在约 2 秒内自动拉直并导出 112 KB 的 A4 PDF,目的是解决用户把护照/身份证上传到免费转换站带来的隐私风险。工具免费、无账号、无水印,目前主要不确定点是用户信任,尚未出现任何付费意愿或收入数据,且同类竞品众多。
