About Mem AI

What Is Mem AI?

Mem is an AI-first personal knowledge base that learns from everything you write and automatically surfaces the most relevant information when you need it. Unlike traditional note apps where you create a folder structure and manually file notes, Mem uses AI to automatically organise, connect, and surface your knowledge — functioning as a genuine "second brain" that grows more useful the more you use it.

Automatic Organisation

Capture notes, meeting summaries, research, and ideas without worrying about where to file them — Mem's AI automatically detects topics, people, projects, and concepts in your notes and connects them to relevant existing knowledge. Open a note about a client and Mem shows you every other note mentioning that client automatically.

AI Knowledge Assistant

Ask Mem questions about anything you've ever written: "What did I promise to send John last month?" or "What are all my notes about machine learning?" — and Mem searches your entire knowledge base to surface specific answers with citations to the source notes. It works like a personal AI that knows only what you know.

Contextual Drafting

When drafting new notes or documents, Mem's AI pulls in related past notes as context — so writing a meeting agenda for a client call automatically surfaces your notes from the last three calls with that client. Your institutional memory is always available in context.

Daily Summary

Mem generates a daily Smart Summary — a curated briefing of your most important notes, upcoming commitments from note content, and suggested follow-ups based on past conversations and tasks identified in your notes.
