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.
If you are weighing options, Notion suits structured team wikis, NotebookLM answers only from sources you upload, Glasp centres on web highlights, and Granola focuses on meeting notes. Not sure which fits your workflow? Smart Match can narrow it down from a short description of what you do.
Pricing
Free plan available. Mem Plus is $9/month, Mem Pro is $29/month, and larger Pro tiers run $49, $99, $149 and $199 per month. Allowances scale with the tier.

Frequently Asked Questions
How much do you pay for Mem?
The vendor lists a free plan, Mem Plus at $9/month and Mem Pro at $29/month, checked 2026-10-11. Larger Pro tiers raise the allowances and cost more: 2x is $49, 5x is $99, 10x is $149 and 20x is $199. Pro adds one custom routine and one connection that Plus does not have.
Can you use Mem without paying?
Yes. The free plan covers light use of the Mem Agent, along with task tracking and a few hours of Voice Mode. Custom routines and connections to outside apps are left to the paid plans.
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 Plus or Pro raises the monthly note and message allowances 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.
