    Any idea why this would not be compatible with Vivaldi 7.5.3735.66? The store says "This item is not compatible with your current Chrome version"

    I’ve developed a couple of fine tuned t5 grammar correction models. Is the model or training open?

      Interesting, I would love to hear how well those worked.

      Grammit uses the Prompt API for the local LLM, which currently uses a version of the Gemma 3n model on Chrome.

      Grammit uses prompting instead of fine-tuning or custom training. Simplified, it has a system prompt along the lines of: "Rewrite this text, correcting any grammar or spelling mistakes," combined with a prefilled conversation containing a number of examples showing an input sentence and the corrected output.
