Mem.
AI-native notes app — self-organising memory for founders and operators.
What it is.
San Francisco-based notes app rebuilt around AI-native retrieval. Mem skips the folder-and-tag scaffolding most notes apps require — notes self-organise via embeddings, surfacing connections across the corpus on every query. Mem X, the assistant layer, drafts, edits, and answers questions grounded in the user's own writing. Backed by Andreessen Horowitz with early backing from OpenAI's Startup Fund.
Where it fits.
Solo operators, founders, and writers who want their notes to behave like a second brain rather than a filing cabinet. The pitch lands hardest with users who have abandoned Notion and Roam for being too structured. Less suited to team documentation where shared hierarchy and access controls matter more than retrieval magic.
- Self-organising — no folder or tag overhead
- Embeddings-based retrieval surfaces connections across notes
- Backed by A.Capital and OpenAI Startup Fund
- Team collaboration features lag Notion by a wide margin
- Pricing per seat steep for what remains a notes app
Frequently asked.
How is Mem different from Notion?
Mem self-organises via embeddings — notes surface by semantic relevance, not folder placement. Notion is structured, hierarchical, and collaborative. Different tools for different brains.
Does Mem work offline?
Limited offline editing on the desktop app. AI features and cross-device sync require connectivity. Mobile apps cache recently accessed notes.
Is Mem suitable for team documentation?
Not really. Mem is a personal tool first. Teams documenting shared processes still belong on Notion, Confluence, or Coda.
