Can we send the newsletter tomorrow?
Tomorrow is Saturday, and you send on Tuesdays after Sarah signs off. Want me to draft it for Tuesday instead?

It finds what matters, and leaves out what doesn't

74.8% recall on LoCoMo's 397 questions, 86–100% on LongMemEval, and 20 of 20 on our own MemTrapBench-style tasks — all run against the live service.

LoCoMo, a public benchmark

Recall was 74.8% overall across 397 questions, run against the live service. It was lower on some kinds of question.

LongMemEval

Recall was between 86% and 100%, depending on the kind of question, and we did not tune for it.

MemTrapBench method

Its data is not licensed, so we ran our own tasks in its style. The right memory came back in 20 of 20 tasks. In the 5 built to mislead, the misleading memory came back too, next to the right one.

Set up once. Remembered everywhere.

Step 1
Connect your tools
Add the browser extension, or run one command for coding tools. It takes a couple of minutes.
Step 2
Carry on as usual
Chat, code and write as you normally would. There is nothing new to learn.
Step 3
Every tool remembers
Open any connected tool and the context is already there.
Saved instantly

Say it once. It is already saved.

Hivemind saves what you say straight away, so nothing slows you down. Behind the scenes it works out what is worth remembering and files it under the project you picked. Changed your mind? Cancel in the first two seconds, or forget it any time.

Switch tools without starting over

When you move from one tool to another, Hivemind hands over the whole picture: what you decided, what comes next and what to watch out for. The next tool carries on instead of asking you to explain.

Always visible

Ask a question and see exactly what a tool would be told before it answers, and what was left out.

Everything else you would expect

Views
Group memories by topic with a saved search. Deleting a view never deletes what it found.
Threads
A chat in your browser and a session in your editor on the same work stay together as one thread.
Documents and audio
Add a PDF, a note or a recorded call. It becomes memories you can find, not an attachment you have to hunt for.
Your other apps
Pull in the places your decisions already live. Each connection tells you what it reads first.
A weekly digest
A short summary of what your tools learned and what changed, so you never have to go looking.
Export anytime
Take your memories with you as Markdown or JSON, on any plan.

Your memory belongs to you

Hivemind exists to remember what you tell it, so how it treats that matters more than any feature.

You can undo anything
Cancel a save in its first two seconds, or forget any memory later. Everything kept is visible to you.
Fix anything
Every memory is a plain sentence. Rewrite it or remove it whenever you like.
Leave whenever you like
Export it all, or delete your account and your memories go with it.

Free until it is worth paying for

For developers

Building your own agent? Give it the same memory

A TypeScript SDK and a REST API over the same memory your tools use.

agent.ts 
import { Hivemind } from "@get-hivemind/sdk";

const hm = new Hivemind({ apiKey: process.env.HIVEMIND_API_KEY });

await hm.remember({ content: "Newsletters go out on Tuesdays" });

const { payload } = await hm.recall({
  q: "When do we send the newsletter?",
});

Questions people ask first

Do you read my chats?

No. A tool sends what it decides to keep, and you see it as it is saved. The browser extension only captures on the sites you switch on, one at a time, and every save shows a two-second note you can cancel.

Do I need to be technical?

No. The browser extension works like any other extension. The one-line command is only for coding tools, and it is optional.

What if it remembers something wrong?

Open it in the dashboard and change the sentence, or forget it. The next question already reflects the change.

What happens to my memories if I leave?

Export them as Markdown or JSON whenever you like. If you delete your account, your memories are deleted with it.

Are my memories used to train models?

No. We do not use your memories to train models.

Do I have to change how I work?

No. Keep using your tools the way you do now. Hivemind saves and shares in the background, and you only open the dashboard when you want to look.
