What it really isQuillBot — AI writing suite for paraphrasing, grammar, summarization, and content tools.
Our takeQuillBot has grown well beyond a paraphraser into a full AI writing platform: grammar checking, plagiarism detection, AI-content detection, summarization, translation, citation generation, PDF tools, and image generation are all included.
QuillBot is primarily a web app; browser extensions are just one way to access it. Current monthly billing is $19.95/mo, with the annual rate at $8.33/mo.
Why we rate itRare combination of depth (10+ tools) and accessibility (generous free tier, student pricing, browser extensions, Word add-in, mobile apps) makes QuillBot the default writing assistant for millions of students and non-native English writers.
The catchFree plan is restrictive (125-word paraphrase limit); plagiarism checker and full AI detector are premium-only; monthly billing at $19.95/mo is steep compared to the $8.33/mo annual rate.

Trade-offs

Friction report

Trade-offs to know before signing up.

  1. Time to value
    Fast: free account requires only an email; core paraphraser is usable within 60 seconds of signup.
  2. Scale breakpoint
    Per-seat Teams pricing climbs at 20+ users; no enterprise SSO or advanced admin controls beyond the Teams tier.
  3. Walled garden
    Moderate: content lives in QuillBot's editor with no public API; exports rely on manual copy-paste or file download.
Still a fit?
If none of these block you, start on the free plan.
