QuillBot

QuillBot is an AI-powered writing platform built around one core strength — paraphrasing — and expanded into a full writing toolkit: grammar checking, plagiarism detection, AI content detection, AI humanizing, summarizing, translation, and even AI chat and image generation. Trusted by 6M+ users with a 4.7 rating, it’s used heavily by students, academics, and content creators who need to rewrite, polish, and verify text quickly.

Unlike tools built primarily to generate new content, QuillBot’s strength is working with text you already have — rewording sentences in different tones and modes, cleaning up grammar, checking for plagiarism, and humanizing AI-generated text so it reads more naturally — all from one subscription with browser extensions and apps that work wherever you write.

Key Features

• AI Paraphraser with multiple rewriting modes
• Grammar Checker for error correction and style suggestions
• Plagiarism Checker to catch unintentional overlap with existing sources
• AI Content Detector to check whether text reads as AI-generated
• AI Humanizer to make AI-generated text sound more natural
• Summarizer for condensing long text into key points
• AI Chat and AI Image Generator
• Translation tool
• Browser extensions and apps that work across the sites and apps you already use

Who Should Use QuillBot?

• Students and academics who need to paraphrase, cite, and check plagiarism
• Content writers and marketers rewriting or repurposing existing text
• Non-native English speakers who want grammar and fluency support
