Frequently asked questions

Will it change my writing style?

No — the prompt instructs the model to preserve your voice and only fix clear errors. It won't rephrase sentences unless they're truly incomprehensible. For style improvements, use the AI Rewriter.

Does it handle non-English text?

Yes — modern models support many languages. For best results on non-English text, use Qwen 2.5 or a model specifically trained on that language.

Which model is best for grammar correction?

Llama 3.1 8B and Mistral 7B are both excellent. Phi-4 (14B) gives the most nuanced corrections if you have the RAM.
