How does the grammar checker work?

FixPilot uses the LanguageTool API, an open-source grammar checking engine powered by AI. It analyzes your text for grammar rules, spelling, punctuation, and style, providing specific suggestions for each issue found.

Is there a word limit?

The free tier supports texts up to approximately 10,000 characters per check. For longer texts, split them into sections and check each separately.
