What our research says

Mem

Mem is one of the few note apps where the agent actually follows up on what you wrote, tracking open tasks and nudging you, rather than only answering questions. The pricing is now a quota ladder: Plus at $9 is cheap but caps you at 50 messages and 50 new notes a month, so anyone who captures daily will land on Pro at $29 or above.

Pros

  • Agent tracks tasks and projects across notes and sends proactive nudges
  • Voice capture and bot-free meeting notes feed the same workspace
  • Developer API and MCP server for connecting other tools
  • Markdown export of notes and collections

Cons

  • Every tier caps new notes and agent messages per month, so cost scales with how much you write
  • Routines and connections start only at the $29 Pro tier
  • No Android app on the download page

Tanka

Tanka is easier to evaluate through press coverage and its founder's track record than through its own website, which is still mostly a sign-up page with placeholder sections. The pitch, persistent shared memory as infrastructure for teams working alongside AI agents, is a real and increasingly common category, but there is no public description of what the product screen actually looks like or does day to day. Treat this as a pre-launch or early-access company to watch rather than a tool ready to evaluate hands-on.

Pros

  • Founder has direct prior experience building AI memory products
  • Announced funding and press coverage suggest real institutional backing
  • Mobile app listing exists on the App Store

Cons

  • Public website shows no concrete feature list, screenshots, or pricing
  • Access is gated behind an early-access signup rather than a self-serve trial
