QuillBot
Verified working Aug 7, 2026
AI tools for rewriting, editing, citations, and originality checks.
QuillBot is a writing and creation platform centered on AI-assisted editing, paraphrasing, grammar correction, summarization, translation, citations, and originality checks. It also includes adjacent tools for chat-based brainstorming, image generation/editing, presentations, PDFs, and file conversion, with apps and extensions for using it across common workflows.
Why it stands out
- Combines rewriting, grammar, citations, plagiarism checks, AI detection, and summarization rather than focusing on only one writing task.
- Works beyond the website through Chrome, Edge, Safari, Word, iOS, Android, Windows, and macOS options.
- Includes document, PDF, image, and presentation utilities alongside core writing tools.
- Serves a broad range of writing contexts, from academic work to job applications, business communication, and marketing copy.
- Large user base and browser-extension presence make it a mature option among AI writing assistants.
Good to know
- Some capabilities are tied to a Premium subscription, though the page does not specify exact free-tier limits.
- AI and plagiarism detection should be treated as screening aids, not definitive judgments.
- Uploaded files and images must comply with copyright and community rules, so users need to verify they have the right to use their materials.
Under the radar: If you mainly know QuillBot for paraphrasing, check its PDF and file-conversion sections too; several basic document utilities are available from the same tool hub.
