About Mem
Mem is an AI-powered note-taking and knowledge management platform designed to capture ideas, meetings, and research—then resurface them exactly when you need them. Unlike traditional note-taking apps that require manual organization with folders and tags, Mem uses artificial intelligence to automatically connect related content, organize information intelligently, and enable retrieval through natural language queries. The platform eliminates the cognitive burden of information organization, allowing users to focus on thinking rather than filing. Mem offers a unified workspace accessible across web, Mac, Windows, and iOS, with features including Voice Mode for meeting transcription, Mem Chat for querying your knowledge base, Collections for topic-based grouping, and Smart Search for contextual retrieval. Founded in 2019 and backed by OpenAI's Startup Fund and Andreessen Horowitz, Mem serves solopreneurs, executives, product managers, and knowledge workers managing high volumes of notes, research, and meeting documentation.

Frequently Asked Questions
How does Mem organize notes without folders?
Mem uses artificial intelligence to automatically link related notes based on content similarity and context. Instead of you deciding where a note belongs, Mem's AI surfaces relevant notes contextually when you need them. You can optionally use Collections (topic-based groupings) and tags, but Mem's AI handles the heavy lifting of discovery and connection.
What is Mem Chat and how does it work?
Mem Chat is an AI assistant powered by GPT-4 (via OpenAI partnership) that's trained exclusively on your personal notes and knowledge base. You can ask it questions like 'Summarize my notes about [client name]' or 'What did I learn about [topic]?' and it draws from your actual documents rather than generic web data. This makes responses highly personalized and contextual to your work.
What's included in the free plan vs Mem Pro?
The free tier allows 25 new notes and 25 chat messages per month, with basic features only. Mem Pro ($12/month) unlocks unlimited notes, unlimited chat messages, unlimited deep searches, AI model selection, dark mode, templates, collections, connected emails, and API keys. All meaningful AI features require the Pro plan.
Is Mem available on Android?
No. Mem currently supports Web, Mac, Windows, and iOS only. An Android app is on the future roadmap but does not yet have a release date. Android users can access Mem through the web app or by sending SMS texts to save notes.
Can I use Mem offline?
Desktop apps (Mac and Windows) support offline editing with full content access; changes sync automatically when you reconnect to the internet. iOS and web versions have limited offline functionality. AI features (Chat, Smart Search) require an internet connection to function.
