Runs on your machine
Ask it why, not just whether
A language model you download into this tab and run on your own processor. Paste an error and ask what it means, or ask for an idea in different words. Nothing you type leaves your browser, and none of it costs anything.
Run a language model on your own computer.
It downloads once, then runs entirely in this tab. No account, no key, no cost, and nothing you type is sent anywhere. How fast it answers depends on your machine.
The conversation appears here once a model is loaded.
A small model makes mistakes. The lessons and the judge are the sources of truth here.
Why it is free
It runs in your tab. There is no server to pay for, so there is no usage limit and no account.
What it costs you
A download the first time, then your own processor. Speed depends on your machine, which is the honest trade.
What it is not
It is not marking anything and it is not authoritative. A small model run locally gets things wrong; the lessons and the judge are what to trust.
