Quillbot
AI paraphrasing tool and writing suite for rewriting, grammar checks, and originality scans.
QuillBot is the budget pick for anyone who rewrites text for a living — the Paraphraser plus Grammar Checker and Plagiarism Checker cover 80% of what students and non-native writers actually need, and the free tier lets you test all of it before paying. It won't out-analyze Grammarly on tone or ProWritingAid on style reports, and its plagiarism scan isn't a substitute for Turnitin. Buy it for paraphrasing and originality, not for deep writing coaching.

The free tier limits paraphrasing to 2 modes and caps summarizer at 1200 words, so heavy users will feel the need to upgrade.

About Quillbot
QuillBot is an AI writing and paraphrasing platform used by more than 35 million writers across 180+ countries. Its core job is rewriting: paste text into the Paraphraser and it restructures sentences while keeping your meaning, with modes like Standard, Fluency, Formal, Creative, Expand, and Shorten. Around that hub sits a writing suite — Grammar Checker for fixing spelling and grammar, Summarizer for condensing long articles, Translator, Citation Generator for APA/MLA/Chicago references, and a Cover Letter Generator. Originality is the second half of the pitch. The AI Detector flags text that reads as machine-written, an AI Image Detector does the same for generated visuals, the AI Humanizer reworks flagged text to sound more natural, and the Plagiarism Checker scans against web sources so you catch overlaps before submitting. For students and non-native English speakers, that trio covers most of the daily anxiety: will this read as my own writing, and is it clean? A third layer handles creation and file work. AI Chat brainstorms and drafts, the Image Generator turns prompts into visuals, the AI Image Editor and Background Remover clean up photos, and the Presentation Creator builds slide decks. PDF tools cover editing, merging, splitting, reordering, rotating, extracting and deleting pages, plus ChatPDF for asking questions about a document. Word, Excel, PowerPoint, PDF and image converters round out the file-conversion set. It runs where you already type: Chrome, Edge, Safari, and Word extensions, plus iOS, Android, macOS and Windows apps. Compared with Grammarly, QuillBot leans harder into paraphrasing and originality checking and bundles PDF and image utilities that Grammarly doesn't. ProWritingAid still goes deeper on style and readability reporting, and Turnitin remains the institutional standard for database-backed plagiarism review.
Behind the Verdict
Start with what QuillBot is genuinely good at: rewriting. The Paraphraser's six modes give you real control — Standard when you just need different phrasing, Formal for emails and reports, Shorten when a draft runs long. For non-native English writers this single tool does more day-to-day work than any grammar checker. The originality cluster is the other reason people pay. AI Detector, AI Humanizer, AI Image Detector and Plagiarism Checker sit in one place, so you can draft, scan, and revise without hopping between tabs. In practice we'd treat the AI detector as a signal, not a verdict — no detector is authoritative, and QuillBot's own results are one opinion among several. Where it starts to sprawl is everywhere else. PDF merge/split/rotate, background removal, image conversion, Excel and PowerPoint converters — useful, but they're commodity utilities you can find free elsewhere. If you're paying Premium only for those, you're overpaying. The Paraphraser and Grammar Checker are the value. Pick QuillBot if you're a student, job seeker, or non-native writer who rewrites constantly and wants paraphrasing, grammar, citations, and a plagiarism scan under one cheap subscription. Pass if you need deep tone analysis, readability scoring, or sentence-level style coaching — Grammarly and ProWritingAid are built for that, and QuillBot's grammar suggestions stay fairly surface-level. Also pass if your institution requires database plagiarism checks. QuillBot scans against web sources; Turnitin compares against published journals and a submission archive. Those are different jobs. The extensions are the quiet win. Chrome, Edge, Safari, and Word add-ins mean the Paraphraser follows you into Google Docs, email, and Canvas instead of living in a separate tab. If your workflow
