Spin Alex’s world.
Alex Rivera is made up. Their world is what SecondMemory builds from a few weeks of mail, calendar and meetings: the people, places, projects and promises, each with where it came from. Drag it, tap someone, and try asking.

What did I promise Priya?
Claude checked Alex's memory · 3 memories
The Q4 roadmap draft. You told Priya you'd send it by Friday, ahead of Monday's roadmap review.
Switch AI: the same memory gives the same answer, from the same message.
This is a sample world.
Yours is built from your mail, calendar and meetings.
Any AI
Alex’s memory goes where Alex goes.
Like the memory in Alex’s head, it isn’t left behind in one app. Alex plugs it into Claude, ChatGPT, Gemini or Grok, and each one knows the same Alex, with the same sources.
Claude, ChatGPT, Gemini and Grok each connect to the one memory, whose keys stay on Alex’s phone.
Plug it in once per AI
Alex pastes one address into the AI and approves it on their phone. From then on, that AI can look things up and add new ones.
Switch whenever
Try a new AI, use two side by side, or stop using one. Nothing to teach again, and nothing is lost.
It stays with Alex
The memory isn’t kept inside any AI. Alex holds the keys on their phone and can download all of it, any time.
Works with AIs that let an outside memory plug in: Claude on every plan, ChatGPT in developer mode on some paid plans, Gemini for personal accounts in the US, and Grok on paid plans. Checked 24 September 2026, and Grok on 31 October 2026.
In your own memory, it’s yours alone.
Your world is sealed with keys your phone holds. Every AI has to ask, and the Private drawer opens only with your fingerprint or face unlock.
