Mem is an AI note-taking and knowledge-management tool available on 4 platforms (web, Mac, Windows, iOS) that automatically links and resurfaces a user's notes, meetings, and research without manual folders or tags. Its AI chat is trained solely on the user's own notes, unlike general-purpose assistants that draw from the open web.
About Mem
Mem is an AI-powered note-taking and knowledge management platform, founded in 2019 by Kevin Moody and Dennis Xu and backed by $29.1M in Series A funding led by OpenAI's Startup Fund and Andreessen Horowitz. It captures ideas, meetings, and research, then uses AI to resurface that content instead of requiring folders or manual filing.
The platform serves solopreneurs, executives, product managers, and researchers who produce more notes than they can file by hand, running as one workspace across web, Mac, Windows, and iOS.

Frequently Asked Questions
How much do you pay for Mem?
Mem Pro runs $12/month (or $14.99 on some billing pages) and removes the caps on notes, chat messages, and deep search. The upgrade also adds Collections, reusable Templates, a choice of AI model, and a dark theme. Mem Teams uses custom pricing with group billing, priority support, and SLAs for larger organizations.
Can you use Mem without paying?
Yes, within caps: 25 new notes and 25 AI chat messages a month, with basic search only. Collections, templates, deep search, dark mode, and AI model selection are reserved for the paid Mem Pro tier.
What should you use instead of Mem?
Notion suits teams that want structured databases and wikis rather than freeform AI capture. NotebookLM fits research that must stay grounded strictly in documents you upload, since it only answers from sources you add. Glasp is built around marking up and sharing clips from articles and PDFs rather than keeping a private notes archive.
Mem or Notion: which should you pick?
Notion centers on structured pages, databases, and multiplayer editing, all of which need setup before they are useful. Mem centers on frictionless capture, with AI organizing new notes automatically and no setup step at all. Team wikis and project tracking are Notion's ground; a fast personal capture layer is Mem's.
How long does it take to get going with Mem?
There is no setup phase, which is rather the point. Open the free plan at mem.ai, then start capturing notes, meeting audio through Voice Mode, or web clips and let the AI organize them instead of building folders first. Moving up to Mem Pro for unlimited chat and deep search is a few clicks from inside the app.
Top Alternatives
- Notion: Notion is the structured option for databases, wikis, and team collaboration; Mem drives AI capture that skips manual setup.
- NotebookLM: NotebookLM keeps answers grounded in documents you explicitly upload, while Mem continuously organizes your own running notes.
- Glasp: Glasp is for highlighting and sharing passages publicly from the web and PDFs; Mem is the private, AI-organized home for your own notes and meetings.
