About Cohestry: Second Brain
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.

What’s new
Version 1.1 · Updated October 22, 2026
Cohestry 1.1 gives you more ways to catch a thought than typing. • Duo Support: new layout to support and optimize for the coming Duo phone • Voice notes. Record into any note, or straight from Capture. Cohestry transcribes the recording on your device and adds the words to your note, so a spoken thought is ready to read and search. Your audio never leaves your devices except through your own iCloud. • Drawing. Sketch with your finger or Apple Pencil, in a note or from Capture. The drawing sits in your text like a photo; tap it to keep drawing. • Mark up PDFs. Tap a PDF in a note to highlight, write and draw on it. Your marks are saved into the PDF. • Import PDFs. Bring in PDFs along with Markdown and Cohestry backups, and each one becomes a note. Import now sits right beside Capture on Home. • Two panes on wide screens. On iPad in landscape, or iPhone Duo held open like a book, the list stays beside the note you're reading. • Smoother typing in the editor, and a tag goes away once no note uses it.
