You know how you read something important, feel like you understood it, and then two days later you can barely remember what it was about? Cognir fixes that. Every sentence you select, you write one thought about it. That's it. Then it builds a map of how your thoughts connect. You don't forget things you've thought about. You don't forget things you've thought hard about. Cognir forces you to do so.
Understanding is more valuable than storage: A Zettelkasten is literally a personalized study guide that builds itself.
