    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.

      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"
