Wrist pain from online whiteboards, so I built an app to write for me

I have a few online courses a week, specifically math, where I have to write on the whiteboard. However, I have wrist problems and handwriting issues, so every lesson my instructor would ask what I wrote and my wrist also just hurt. So I built an app in WPF to let me type or talk and it writes for me. It registers a virtual pen with Windows and draws like a normal pen, and that's why it works with any whiteboard app. Also the reason I didn't use text is because many whiteboa

AI 分析

痛点:手腕疼痛或有书写障碍的学生/老师在在线白板(尤其数学课)上无法顺畅手写公式,现有白板对 LaTeX 支持差、文本输入又不通用。

目标用户:有手腕/手部伤病或书写障碍的在线学生与教师,尤其是 K12/大学数学、理科网课人群,以及做手写演示的远程讲师。

证据:I have wrist problems and handwriting issues, so every lesson my instructor would ask what I wrote and my wrist also just hurt... we were able to do a noticeable amount more (like 20% more)... If you have a similar problem you can get it for free on the Microsoft Store.

变现:面向个人低价买断或订阅(如 4.99–9.99 美元/月);更可行的是转向 B 端与教育机构/无障碍合规采购(高校残疾学生服务办公室、网课平台按席位授权),并提供白板软件厂商的 OEM 集成授权。

MVP:两周内做一个 Windows 桌面工具:全局热键唤起输入框,输入文字或语音(Whisper API)→ 转 LaTeX/公式 → 通过虚拟笔在任意白板(OneNote、Zoom 白板、Miro)上以手写笔画动画绘制,支持笔迹粗细与书写速度调节,先只做 Windows + 数学公式场景。

竞品:Microsoft OneNote 的墨迹转文本/数学助手、Miro / Figma 的白板文本工具、Mathpix(公式识别,反向流程)、MyScript / Nebo、各类语音转文字输入法(无法在白板绘写)

摘要:一位有手腕问题的用户在 r/SideProject 发布了自己用 WPF 做的 Windows 应用:打字或说话即可通过虚拟笔在任意白板上“手写”,他自述上课效率提升约 20%、手腕不再疼,目前在 Microsoft Store 免费提供。痛点真实但非常小众,发帖人未提及任何付费意愿或收入数据,免费发布意味着价格敏感度高。独立开发者复刻门槛低(虚拟笔 API + 语音转公式),变现更可能来自无障碍/教育机构的 B 端采购而非 C 端订阅。
