gambalf

An assistant of your own

One body
Many minds

Works with Claude, ChatGPT, Gemini, Grok, DeepSeek, Muse Spark, MiMo, anything on OpenRouter, or a model on your own machine.

Your questions, projects, and ideas — one assistant, powered by the models you choose

Wherever you are

One account, one set of conversations. Open the one you left on the desk from the phone in your pocket, and carry on where it stopped.

  • On your PC

    The whole thing: your files, your terminal, your browser. It works in the folder you opened, on the real files.

  • In a browser

    Sign in from any machine and the same conversations are there. The work can stay on your own PC while the tab just watches it happen.

  • On your phone

    Install it straight from the browser. Ask for something on the way home, get a notification when it needs you, and answer it there.

Two ways in

What did you come for?

Same account, same conversations, same models — the other half is there whenever you want it.

Chat

Ask, understand, create.

Bring anything in, on whichever model you like. It remembers, and it carries on wherever you are.

Code

Plan, edit, run, verify.

It works on your own files and your own terminal, and stops for the decisions that matter.

Not one model
A cast

Everything else hands the whole job to one model and bills you at its rate. Gambalf gives each part of the job to the model you picked for it.

The planner
A model that's good at thinking reads the problem and decides what to do.
The worker
A cheaper, faster one carries it out — the edits, the commands, the reading.
The checker
A different model reads the result before the job is allowed to be called done.
The one in the background
Titles, summaries and the small errands can go to the cheapest model you have.

Dark mode toggle

The settings page needs a dark mode toggle.

  • planner read the page and planned the change Claude
  • worker wrote the toggle and its styles MiMo
  • worker ran the tests — all passing MiMo
  • MiMo hands the work back to Claude. Moved up for the browser check.
  • worker opened the page and switched it on Claude
  • checker reviewed the change before finishing Gemini
background named this conversation and kept its summary up to date DeepSeek

Dark mode is on the settings page and it remembers your choice. I checked it in the browser rather than guessing.

  1. 01

    Reuse your cast

    Save your model lineup once and use it in any conversation—or keep the whole job on one model.

  2. 02

    Moves up when needed

    If a lighter model can't handle a step, Gambalf hands it to a stronger one and lets you know.

  3. 03

    Costs, broken down

    See what every phase costs and exactly where lower-cost models saved you money.

What it actually does

Three ways people use it — and it's the same assistant in all of them.

Just talk to it

Ask it anything

It reads what you drop in, searches the web when it needs to, and makes pictures when you ask for them.

  • Any model, one conversation

    Bring a photo, a PDF or a spreadsheet, and change models without losing the thread.

  • It remembers what matters

    Facts you'd otherwise repeat every time carry into the next conversation.

  • Out loud, if you like

    Dictate, have replies read back, or leave it in voice mode and just talk.

Put it to work

Hand it a whole project

It plans the approach, edits across your files and runs your commands — and stops for you before anything that matters.

  • Plans before it acts

    Agree on the approach first. Nothing is touched until you say go.

  • Checks its own work

    It opens your app in a browser and looks, instead of telling you it probably works.

  • As careful as you want

    A quick answer, or test and review everything before it calls a job done.

The rest of your life

It isn't only for work

Money, travel, health, cooking, gardening, careers — twelve areas, and each one knows exactly what it's allowed to touch.

  • A calendar that plans with you

    It reads what's coming and proposes, instead of leaving you to fill in boxes.

  • Jobs at a time you pick

    Say when, and it does that one job then and tells you what it did.

  • Encrypted on your own disk

    Your life folders are encrypted, with the key in your system keychain.

The models you want
From the providers you choose

Use the key or subscription you already have, a model served on your own machine, or your own endpoint. Gambalf never sits between you and whoever you're paying.

Where it stands

Better you read this here than find out after you're in.

Anyone can sign up
Not yet. We're inviting people from the waitlist in batches, so we can keep up with the feedback.
macOS and Linux
Windows first. The other two come after the preview.
An app in the stores
The phone version is the web app — you install it from the browser. There's nothing to download from a store.
A price list
Gambalf is free while it's in preview. There will be paid plans later, and we'll say so before there are.
