Every AI you open starts as a stranger.

Not anymore.

Today you explain yourself to every AI, again and again. SecondMemory remembers once, for all of them. Your people, your plans, what you promised and what you were promised, each with the email or meeting it came from. Ask ChatGPT, Claude or Gemini, and get the same answer.

It just remembers.

  1. Connect.

    Your email or your calendar. Pick one to start. Add more whenever you like.

  2. It remembers.

    The people, the promises, the plans. What changed, and when. It keeps up on its own.

  3. Ask any AI.

    “What did I promise Sam?” You get the answer, and the email it came from.

Now look inside one memory.

An email, a chat, a meeting. “I’ll send you the budget by Thursday.”

Meeting notes

Meetings, remembered.

Capture meetings with your watch, your phone, or soon the SecondMemory Pod, or connect the notes you already take. SecondMemory pulls out what was decided, who is doing what, and every promise, each linked to the line it came from. Before the next meeting, it tells you where you left off.

Capture it anywhere.

Privacy

Private. Seriously.

Your memory is stored locked, and the key lives in your phone’s secure chip. Every AI has to ask first. The most personal things sit in a private drawer that opens only with your face or fingerprint. Nobody can read your memory without your phone. Not an AI. Not a hacker. Not even us.

For people who code

Coding agents forget everything, every session. So they re-read your files, re-ask your conventions and suggest the thing you ruled out last week. SecondMemory remembers the decisions, the reasons and how you like things done, for every agent you use. Shorter sessions. Less context. A smaller bill.

Six promises we won’t break.

  • You can take it and go.

    Download the whole thing any time, for free. Every date and every source comes with it.

  • Every AI has to ask.

    You choose which AI can read your memory and which can add to it, and you see every time it did.

  • Every memory shows where it came from.

    Each fact keeps its source and its date, so you can check it in one tap.

  • You confirm every promise.

    If it finds one in a web page or somebody else's email, it waits for your yes.

  • Never trained on. Never sold.

    We make money from subscriptions, and from nothing else.

  • Delete it, and it’s gone.

    One memory or all of it, any time. Deleting destroys its key, so nobody can bring it back. Not even us.

  1. Savings are an upper-range estimate, not a quote. They assume shorter sessions carry about half as much context on every turn (cache reads −50%, cache writes −45% after re-caching fresh sessions), 30% less pasted or re-read input and 15% less exploratory output. Prices are each provider’s public list prices on 27 September 2026 (Anthropic, OpenAI and Google, standard tier). The “40%” figure is a heavy AI user on Claude Opus 5.5. Plan savings use the calculator’s “Runs agents all day” example on Claude Fable 5 (Developer) and the “Heavy API user” example on Claude Fable 5 (Business, per seat), rounded down. Your savings depend on how you work.
  2. Works with AIs that let an outside memory plug in. Today that is 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 (Grok: 31 October 2026).
