Mem is an AI note-taking and personal knowledge management app that captures notes and automatically organizes and links them, aiming to reduce the manual filing and tagging typical of traditional note apps. Version Mem 2.0, released in 2026, added faster performance and deeper AI features described as a 'thought partner' for surfacing relevant past notes during writing or planning. The app is available as native apps for Mac, Windows and iOS as well as a web app, with offline editing that syncs once back online. A free tier covers core note-taking with capped monthly AI usage, while a paid Pro tier raises those limits, and a Teams plan adds shared workspaces for collaboration.
Reflect is a networked note-taking application built around backlinks, so every note can connect to related notes and build up a personal knowledge graph over time. It includes an AI assistant powered by large language models for tasks like transcription, outline generation, and grammar correction, plus end-to-end encryption for privacy.
