Mem

Mem is an AI-native notes app that aims to be a self-organizing 'second brain'. Users capture notes, web clippings, voice memos and emails into a single stream, and Mem automatically tags, links and surfaces related notes using large language models. The Mem Chat feature lets users ask natural-language questions across their entire knowledge base and get answers grounded in their own notes, while Smart Write drafts new content using the user's prior writing as context. Other features include Mem Spotlight for global search, scheduled reminders, collaboration, and integrations with Google Calendar, email and Apple Notes. Mem targets founders, investors, researchers and knowledge workers who dislike rigid folder hierarchies. The product is offered as a freemium web and mobile app, with Mem X being the paid AI tier.
