What it does

Any model

Every frontier model, one menu.
No vendor owns your context.

  • Pick per session, switch mid-work. Same files, a different model.
  • Native dialect per vendor. Each model gets the tools and formats it was trained on, so it works the way it does at home.
  • Second opinions on demand. Run the job again on another model, or hand part of it to one.

  • Finished files, checked

    It hands you the file, not a chat about it, and checks the file is really on disk before it says the job is done.

    • .eml drafts
    • Python
  • Runs on your computer

    The agent, your files and your keys stay on your machine, which is also why it is fast with files. What the model needs goes to the vendor you chose, and Safata lists every request.

Why I built it

I’ve worked in finance, strategy, sales, product marketing, product and engineering, and every one of those seats was knowledge work. I built Safata because I needed a capable agent to test Kimi K3 the day it came out, on real work. The agents I had were each tied to one vendor and its models.

So Safata runs on your computer, on the model you choose: frontier or open, American, Chinese or French. You make the calls. It does the work and writes down what it learns, on your disk, next to your files. Switch models and nothing is lost; the more you use it, the better it gets. That is what owning your context means.

I don’t believe agents replace knowledge workers any time soon. Too much of the work isn’t about capability: context that lives in someone’s head, judgment about what matters, accountability for being wrong, and taste. What I do believe is that a person working with an agent gets to a better result, faster, than either alone. Safata is built for that pair.

Some of that costs me. Your own keys are slower to adopt than an account and a credit card, and with no telemetry I only learn what breaks when you tell me. But a tool this close to your work has to be one you can be relaxed about, including about me. If I stopped tomorrow, everything Safata made for you is an ordinary file on your own disk, and your keys are your own.

How I use it

Safata is Catalan for tray: a place where you can put anything you want.
