Made for readers who want the reading to stick.
If you read a lot but rarely apply what you read, you're not alone. The average highlight is forgotten within weeks. Ingrain is built for the true mass reader, the person who does not just want to finish books, but to live them.

How it works
From page to practice in three steps.
2
Choose one behavior
AI turns the idea into a small, specific practice sized to your life: a single behavior you can repeat.
3
Practice & keep track
Gentle reminders, streaks, and a weekly review keep the thread, so growth compounds instead of fading.
AI inside
Serious intelligence, quietly doing the work.
Ingrain uses modern AI where it actually helps, so you spend your energy practicing rather than organizing.
Reads your highlights
Photograph a page and AI extracts the highlighted passage automatically.
Tailored practices
Practices are shaped by your growth profile: your focus areas, pace, and time.
Search by meaning
Find the right passage by what it means, not the exact words. Semantic search covers everything you have saved.
Weekly reflection
An AI coach reviews your week and points you toward what is next.
Bring your own AI
Connect Ingrain to ChatGPT, and any AI agent.
Your library becomes a tool your favorite assistant can use. Ingrain speaks the open Model Context Protocol (MCP), so ChatGPT, Claude, Cursor and any MCP-compatible agent can read your highlights, draft practices, and review your week, on your command.
- Works with ChatGPT connectors and any MCP client
- A secure, per-user agent key, so your data stays yours
- 16 tools: capture, search, practice, reflect, and more
