What our research says

Exogram

Exogram has turned from an agent policy gate into a personal memory workspace: one vault of your context that several AI models and coding tools can draw on. It suits people who switch between ChatGPT, Claude and Gemini and are tired of re-explaining themselves. The pitch is heavy on jargon and self-reported speed figures, and it asks for very personal data, so judge it on the free tier first.

Pros

  • Free plan with unlimited bring-your-own-key use and no card
  • Imports existing memory exports from ChatGPT, Claude and Gemini
  • MCP server and browser extension bring the same memory into other tools
  • Full JSON and markdown export of the memory vault

Cons

  • Marketing pages still list older model versions such as Claude 3.7 and GPT-4o
  • Latency and capability claims are self-reported with no outside benchmark
  • Run by a single founder, so continuity of a vault holding personal data is a real question

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
