Zenpa

Zenpa is a Mac app that builds a private memory of your emails, chats and notes and answers questions about them with sources. Everything is processed on the Mac itself, which suits freelancers and consultants handling confidential client work.

It gathers information scattered across tools such as Gmail, Slack and Notion into a memory vault you can query, so you can find a decision, date or spec without digging through threads. It also offers private chat and drafting, local meeting transcription and notes, dictation in any text field and web research.

Zenpa is made in Switzerland and stresses that your data never leaves the device or reaches a cloud model. Plans are monthly, yearly or a limited lifetime licence, each with a 7-day free trial.
