Stop Forgetting What You Read.

Scan your Physical books, sync your Kindle notes.
Save highlights instantly, find hidden connections, and chat with your library.

One Home for All Your Highlights.

Most apps are just storage buckets. Synapse is an active engine that thinks with you.

Scan Physical Books

Don't type notes manually. Snap a photo. Our "AI Janitor" cleans up headers and page numbers automatically.

Sync Kindle Highlights

Import your My Clippings.txt file in seconds. Organize all your digital notes instantly.

Find Hidden Connections

Synapse links your new notes with your old highlights. "💡 This contradicts your note from Deep Work..."

Chat with your Library

Ask big questions like "How do I build better habits?" and get a synthesized answer citing your books.

How it Works

1

Capture the Page

Snap a photo of any book page. Select the paragraph you want to keep, and our AI cleans up the formatting instantly.

Scan Screen
2

Get a Spark

The moment you save, Synapse searches your entire library. If it finds a connection to an old book, you get a "Flash Insight."

Insight Screen
3

Talk to your Books

Use the Chat tab to interrogate your library. Compare authors, summarize topics, or find that one quote you forgot.
