## What is Cohestry?

Cohestry is a second brain for people who want their notes to become more useful over time.

Capture ideas, thoughts, references, and unfinished threads in one place, then let Cohestry help you see how they connect. Instead of leaving notes buried in folders, Cohestry turns your knowledge into something you can explore, revisit, and build on.

EXPLORE YOUR THINKING

Cohestry visualizes connections between your notes as an interactive 3D brain, making it easier to spot related ideas and understand how your thinking is developing.

REDISCOVER WHAT MATTERS

Worth Revisiting brings older notes back into view so useful ideas do not disappear into an archive.

Today’s Insight surfaces a connection from your existing notes, giving you a reason to return to ideas you may have forgotten.

WRITE WITHOUT FRICTION

Create and edit rich notes with support for formatting, lists, tables, images, and more. Cohestry is designed to work as a complete notes app, not just a layer on top of one.

BRING YOUR APPLE NOTES WITH YOU

On Mac, import your existing Apple Notes and start building from the knowledge you already have.

BUILT FOR APPLE

Cohestry is a native iPhone and Mac app designed around a simple idea: your notes should become more valuable the longer you keep them.

Core note-taking features are free, including unlimited notes and Apple Notes imports. Advanced connection features are available with Cohestry Pro.
