Your work has a history.
Your assistant should, too.

where you left off.
Doppel is a personal AI assistant for Mac. It builds a memory from the files, meetings, screen activity, and connected services you choose, so you can ask about work beyond your current conversation.
Find the decision. Check its source. Prepare the follow-up. The background is there when you need it.

Under your control.
The personal part matters as much as the assistant part. These choices shape how Doppel works.
Keep personal memory on your Mac.
Doppel stores your work memory and runs its built-in AI locally. Connected services make their own requests when you use them, with clear boundaries around what is shared.
Keep the source within reach.
An answer should help you find the original, not replace your judgment. Open the source, check the details, and review an action before approving it.
Made for your Mac. And your way of working.
