Byeori is a notes app for people who have been writing things down for years and never go back to read them.

Bring your notes in from Day One, Apple Notes, Notion, Obsidian, Google Keep, Evernote or Markdown files. Folders, tags and dates come with them. Byeori then reads everything and shows you:

• What you keep coming back to: themes that return across months or years, quoted in your own words, with how your thinking moved over time and the question you still haven't answered.

• Where your notes pull apart: two things you wrote that don't agree.

• Around this note: while you write, the older notes this one connects to.

• A map of everything you've written, grouped into topics it finds on its own.

• On this day: something you wrote years ago, once a day.

Your words are never rewritten. AI features use OpenAI's API (not used for training). You can turn AI off entirely, hide any note or folder from it, and export everything as Markdown or JSON at any time.

Free while in beta. Web, Mac, iPhone and Android.
