Notes pile up. Then what?
Most apps are great for getting thoughts out of your head. But then your notes pile up and you never look at them again.
Flint helps you capture ideas, find connections between them, and come back to what matters—so your notes actually stay useful.
How it works
Write
Capture ideas without friction
- Focus on taking notes, not managing files and folders.
- Note types for different purposes (daily notes, evergreen notes, predictions)
- Daily notes make it easy to capture ideas as they come.
Outcome: Your ideas are always saved.
Connect
Link ideas and find relationships
- Links and backlinks make connections visible and discoverable
- AI agent helps you find related notes and suggest connections
- Build a personal knowledge graph that grows with you
Outcome: Find connections between ideas.
Remember
Come back to notes at the right time
- Review system brings notes back based on spaced repetition
- AI generates prompts to help you engage with old notes
- Backlinks surface where ideas recur across your notes
Outcome: Your notes stay useful over time.
