Mem.ai

An AI notes app that organizes your knowledge for you

AI-assisted note capture

Write or paste ideas, meeting notes and documents into a fast capture surface, and Mem's assistant files, links and enriches them automatically rather than leaving you to build folder structures by hand.

Search that understands your notes

Ask natural-language questions and get answers grounded in your own notes and saved documents, so recall feels more like a conversation than a keyword search.

Automatic summaries and connections

Mem generates summaries and surfaces related material, helping you reconnect an old idea with the work you are doing right now.

Team knowledge workspace

A shared AI-powered workspace gives teams one place where decisions, documents and context stay searchable and reusable across projects.
