6 Best QuillBot Alternatives in 2026 (Free & Paid)
Research reviewed October 2026 — confirm pricing before you buy.
TL;DR: Spinbot is the closest free pick — fully free, no sign-up, basic quality. For paid, Wordtune (from ~$6.99/month annually) gives the cleanest rewrites, and Paperpal is best for academics.
Why people look for QuillBot alternatives
QuillBot’s free plan paraphrases only 125 words at a time and locks you to the Standard and Fluency modes — extra modes, the synonym slider, and the plagiarism checker sit behind Premium ($19.95/month monthly, or $8.33/month on the annual plan). The limits feel designed to nudge you into paying, and if all you need is quick rewrites, you’re paying for a suite you’ll never open.

1. Wordtune — best for clean sentence rewrites
Wordtune suggests multiple rewrites for any highlighted sentence and lets you shift between casual and formal tones — a nicer fit than QuillBot for emails and professional writing. The free Basic plan gives 10 rewrites per day plus unlimited spelling and grammar checks. Paid plans run about $13.99/month (roughly $6.99/month billed annually) for Advanced, or $19.99/month (roughly $9.99/month annually) for Unlimited.
2. Paraphraser.io — best free word budget
Paraphraser.io is the closest like-for-like QuillBot swap: a web paraphraser with six modes, built-in grammar and plagiarism checkers, and 20+ languages. The free tier allows about 600 words per paraphrase — far more generous than QuillBot’s 125 — though it shows ads and limits modes. Paid tiers start at $9/week (Lite) or $23/month (Silver). Reviews rate its accuracy below QuillBot’s, so check long output before trusting it.
3. Smodin — best academic all-in-one
Smodin goes beyond paraphrasing with essay writing, summarization, plagiarism checks, citation generation, and an essay grader — all in 100+ languages. The free starter plan gives a few daily credits; paid plans start around $10/month (Essentials) and $29/month (Productive) for unlimited rewrites and higher limits. Less a pure paraphraser than a student toolbox, with strong non-English support.
4. Paperpal — best for researchers and students
Paperpal is built for academic writing: suggestions tuned to formal academic register, pre-submission manuscript checks, journal requirement screening, and plagiarism scanning inside Word, Chrome, Edge, or Overleaf. The free plan includes 200 language suggestions a month, 5 generative AI uses a day, and 7,000 words a month of plagiarism checking. Prime is $25/month or $139/year. If your writing ends in a journal submission portal, Paperpal fits better than QuillBot; if it’s marketing copy, it doesn’t.
5. Sapling — best for business writing
Sapling is an AI writing assistant for customer-facing teams: grammar and spell checks, sentence rephrasing, tone suggestions, and autocomplete that learns your style, with integrations for Gmail, Slack, and help desks. Free plan available; paid starts around $25/month. Caveat: Sapling isn’t really a paraphraser — it’s a Grammarly-style assistant. Only consider it if your QuillBot use is really “make this email sound better.”
6. Spinbot — best fully free option
Spinbot is a classic article spinner with no paid tier at all: completely free, no account required, handling around 10,000 characters per session. Quality is the weakest here — synonym-spinners produce awkward phrasing that needs cleanup, and output is easy for AI detectors to flag. But for a quick rough rephrase you won’t publish as-is, it has zero cost and zero friction.
Verdict
For everyday writing polish, try Wordtune’s free tier; for academic writing, Paperpal is the specialist pick. If you just need more free words than QuillBot’s 125, Paraphraser.io’s 600-word free allowance is the direct answer, with Spinbot as the no-sign-up backup. Smodin suits multilingual students; Sapling only makes sense for business writing.
FAQ
Is QuillBot still free?
Yes. The free plan includes paraphrasing (125 words per use, two modes), a 1,200-word summarizer, and a basic grammar checker. The plagiarism checker, extra modes, and unlimited words are Premium-only.
Which QuillBot alternative is best for students and academics?
Paperpal, for its journal-aware checks and manuscript screening. Smodin is a solid budget alternative with citation tools. QuillBot Premium stays competitive for students at $8.33/month annually.
Which is the best free paraphraser?
Spinbot is fully free with no sign-up, but quality is basic and needs editing. Paraphraser.io’s free tier gives 600 words per use with better modes, though it shows ads. Wordtune’s free plan (10 rewrites/day) wins on quality.
Can paraphrasing tools beat AI detectors?
Not reliably. Independent comparisons in 2026 show no paraphraser consistently fools modern AI detectors, and tools like Turnitin keep improving at spotting AI-assisted paraphrasing. Use these tools to clarify your own writing, not to disguise AI-generated text.
Bottom line: Wordtune replaces QuillBot for everyday polish, Paperpal for academics, Spinbot for free — but QuillBot Premium at $8.33/month annually is still fair value if paraphrasing is all you do.
