Say it once in Cortesso — how you like answers, who is who, what you decided — and Claude, ChatGPT, Gemini and Grok all remember. Switch apps mid-project, or lose one to an outage, and the next picks up where the last one stopped. It works inside the AI you already pay for. No API key needed to start.
A browser extension for chatgpt.com, claude.ai, grok.com and gemini.google.com. It works on your own account with each of them, on the plan you already pay for. No API key, nothing to paste: being signed in to Cortesso in the same browser is enough.
A pill by the box says 2 from memory. Click to read them, cross one off, or skip it this time. Nothing is added silently.
What bears on this message goes with it, including what you worked out with a different AI yesterday. Small talk is never touched.
The chat is saved to your memory with pasted secrets removed. Select any reply text and choose Remember in Cortesso: one click, every AI.
A six-digit code. No password.
Add Cortesso to Claude or ChatGPT as a connector, or install Cortesso for Chrome. Both run on the plan you already have.
Tell it three things, or drop your ChatGPT export. Then ask Claude something you only told ChatGPT. Two AIs, one memory.
Short answers, metric units, no bullet points, British spelling: say it once. Every AI you connect honors it.
Your sister's name, the dog's vet, the contractor you trust. Facts you add, or that an AI learns in a chat and files with a note saying so.
The move, the trip, the renovation: a project with to-dos any helper can pick up, and a checkpoint of where the last one stopped.
Drop your ChatGPT or Claude export. Your conversations become your memory. Pasted keys and passwords never make it in.
Export everything as one readable zip; delete everything, in one click. Encrypted at rest. Never used to train models.
Connect Cortesso to Claude, ChatGPT or Grok and each one saves where your work got to. If that AI is down — or the tab closed, or the context filled — open another, and it carries on from the same point.
You said it, an app wrote it, or a helper read it somewhere: the memory says which, so you can trust it or fix it.
A helper is a title and a sentence about what it is for. Hire one in a click, edit its rules, ask it anything. They share your memory, so the planner knows what the buyer found.
Turns "we're moving in October" into a plan with dates and to-dos, and tells you every week what is next and what is slipping.
Researches the thing you need to buy, with sources and prices, remembers what you already own and what you hated last time.
Drafts the email, the post, the letter to the school, in your voice, from the facts in your memory. Never sends anything itself.
A coach, a tutor, a travel agent: a title and a sentence. That is a helper.
Positions with job descriptions and rules — CFO, Head Designer, Ops, Sales — sharing one memory of your company. Upload the P&L, ask, and get an answer the way a real CFO gives one. On Pro, the CFO keeps the books: import your transactions and every number is computed, never guessed.
See the business door →We are profitable and cash is fine; the problem is DTC.
What the numbers sayThe price is for Cortesso: the memory that follows you across every AI, the team of positions that remember, the continuity between sessions. None of that costs a token, so none of it is priced in tokens. Positions run on your own engine keys, with the caps you set, and the engine bill is yours at the vendor's price. (New keys are paused during early access.)
What the encryption protects, exactly. Fact names, descriptions, bodies and provenance; event payloads; checkpoints and tasks; your display name, attributes and tone; standing instructions; captured conversations; files; keys. These are encrypted at rest with a key Cortesso holds, so Cortesso can read them and the nightly consolidation pass does. Not hidden: ids, fact types, confidence scores, tags, timestamps, and how often you are active. A passphrase-only mode, where Cortesso cannot read your store at all, is planned and not yet available.
Cortesso is in early access. Sign in with your email; your memory and the connector work on the plan you already have, and positions run on your own vendor keys. US customers first in 2026.
