Grammar slips, misspellings, punctuation faults, homophone swaps (their/there/they're), and run-on sentences. A 1,000-word draft typically surfaces 15–30 flags in one pass — accept the clear wins, ignore stylistic suggestions that fight your voice.
No — the rule-based check runs entirely in your browser and nothing is sent anywhere. Only the optional AI Fix button sends the flagged sentences to the AI API (1 credit per fix); the plain check stays free, local, and offline-capable.
The rule-based check is free and local with no credits and no per-use cap. The AI Fix button costs 1 credit per use — signed-in free plans include a one-time 5-credit trial, Pro gets 200 monthly, anonymous requests return 401. Exporting the corrected .txt counts as one Pro download (signed-in free: 2 a day).
