Synapse

Your tools forget. Synapse remembers.

Keep project decisions and credentials on your Mac, ready for the tools and terminal sessions that need them.

Set it once. Keep moving.

Synapse quietly carries the parts of a project that should survive the next session.

Connect

Bring your tools together.

Connect every tool you use to one local memory and one shared guidance file. Your existing setup stays yours.

Import

Bring useful history with you.

Preview existing memory from either tool, leave suspicious content untouched, and undo any import batch.

Continue

Pick up with the context intact.

Start another session or switch tools without reconstructing the same decisions again.

Control

Keep the final say.

Search, correct, export, or delete any memory from the app whenever you want.

Credentials without the sprawl.

Secret values are sealed in a store only you can open — Synapse's own, or macOS Keychain if you prefer it. Projects receive only the environment variables you approve for them.

Use the boundary for one command, or turn on shell integration in Settings to load an approved environment when you enter its folder.

Nothing hidden.

Your memory stays on your Mac and remains visible in the app. Read the exact text, fix what changed, make a backup, or remove what no longer belongs.
