How this list is ranked

Free plans that put a number on the allowance (credits, minutes, images, messages) rank first, because you can plan around a number; free plans with unpublished allowances follow. Within each group, order reflects how much each free plan lets you make and use; the note below explains it. Trials and paid-only tools are listed after the ranking so you know they were checked.

Why this order (checked 2026-11-02): QuillBot and ZeroGPT both state a word limit per paraphrase: QuillBot 100 words in 2 modes, ZeroGPT 300 words with no sign-up. QuillBot comes first because its free modes are documented on its plan page. Grammarly's Paraphraser is free with an account but its page states no limit.

  1. correctionCorrection
    QuillBot Premium price corrected to $19.95 (we had listed $23.95)

    Our data listed QuillBot Premium at $23.95 a month. QuillBot's Premium page reads '$19.95 USD Per month' in our saved copies from 2026-10-22, 2026-10-23 and 2026-10-27, so we corrected the figure. This fixes our own error; QuillBot did not change its price. The $8.33 billed-annually figure was already correct.
