QuillBot is primarily an AI paraphrasing tool, but its bundled grammar checker is a credible free option for spelling, subject-verb agreement, comma usage, tense consistency, and punctuation across US/UK/Australian English plus four other languages.
- Best for: Authors who want a free grammar checker without Grammarly's word caps or who occasionally need paraphrasing assistance
- Key features: Free grammar checker with no stated word limit, US/UK/Canadian/Australian/German/French/Spanish/Brazilian-Portuguese support, MS Word add-in, Chrome extension, bundled summarizer/citation/plagiarism tools
- Pricing: Free (full grammar checker; paraphrasing capped at 125 words); Premium $9.95/mo or $49.95/yr ($4.17/mo); Student plan $74.95/yr
- Limitations: Grammar engine is shallower than Grammarly or ProWritingAid — catches obvious errors but misses subtle stylistic issues; no manuscript-level reports; primary audience is students/ESL, not novelists
- Caveat for fiction: Applying the paraphrasing tool to your manuscript prose risks rewriting your voice — use the grammar checker only, not the rephraser, on creative work
