Each equation costs me USD 0.0005 to convert. Mathpix gives students 20 free a month. I give 200.

I’m a Physics, CS and Math student. Every problem set, I was retyping equations from textbook PDFs into Overleaf, symbol by symbol. Mathpix solves this, but its free plan stops at 20 snips a month with a .edu email (10 without). I’d hit that in one problem set. ChatGPT and Claude can do it too. But opening a tab, pasting the screenshot, waiting for the reply, then copying the LaTeX back out is too much friction for something I do twenty times a night. So I built Snip, and then I did the

痛点:理工科学生和科研人员每晚要把教材 PDF 或截图里的公式逐个符号重敲成 LaTeX,Mathpix 每月免费 20 次的额度做一套习题就不够用。

目标用户:物理、数学、CS 等理工科学生,以及需要写 LaTeX 论文/习题集的研究生和科研人员。

证据:Mathpix solves this, but its free plan stops at 20 snips a month with a .edu email (10 without). I'd hit that in one problem set. / Paid plan is $2.99/month or $19/year for heavy users. After Stripe fees and model costs, that's still about 80–95% margin. / Each snip costs me about $0.0005 in model costs.

变现:Freemium 订阅:免费每月给 100–200 次额度获客,重度用户用 $2.99/月或 $19/年订阅;后续可加团队/实验室 license、批量 PDF 转 LaTeX 增值包。

MVP:两周内做一个 macOS/Windows 菜单栏小工具:全局快捷键框选屏幕区域 → 调用多模态模型 OCR → 校验 LaTeX 能否编译 → 直接写入剪贴板;本地记录用量,接 Stripe 做免费额度+订阅解锁,不要求注册账号。

竞品:Mathpix Snip、SimpleTex、pix2tex / LaTeX-OCR、ChatGPT / Claude 手动截图转 LaTeX

摘要:一名物理/CS/数学学生做了一个截图转 LaTeX 的 Mac 工具 Snip,单次模型成本约 $0.0005,免费用户用满 200 次也只花约 10 美分/月,因此敢给 Mathpix 10 倍的免费额度(Mathpix 教育邮箱仅 20 次/月)。付费方案 $2.99/月或 $19/年,扣掉 Stripe 与模型成本后毛利约 80–95%。痛点真实但赛道已有 Mathpix 等成熟玩家,竞争空间有限,胜点在于更低摩擦的交互和更大免费额度。
