Show HN: InboxTutor – Learn anything, one email at a time
I built https://inboxtutor.net , a tool (more like a toy) I use to send myself daily lessons over email, generated using Gemini.
ChatGPT and Perplexity offer something similar, but they require opening an app, and their lesson continuity is often weak. I kept getting repeated content. So I built something that works entirely through email. The whole experience lives in my inbox, a place I’m checking anyway.
How it works: 1. Enter what you want to learn (“Teach me Japanese for my trip”) 2. Verify your email 3. Receive personalized AI generated lessons in your inbox daily 4. Reply to any lesson to ask questions, take quizzes, or reshape the content
That’s it. No app. No dashboard. Just email.
You can also attach context using PDFs, URLs, or pasted text you want incorporated into your lessons.
I’ve found it a nice async way to learn and thought I’d share it here.
