Humanit — AI Writing Assistant

Rephrase to sound natural, fix grammar, paraphrase, and summarize — right where you write.

Humanit brings five AI writing tools to every text field on the web — humanizer, AI detector, paraphraser, summarizer, and grammar fix — so you can improve your writing right where you type, without switching tabs. HOW IT WORKS Select text on any page and a small Humanit button appears. Pick a tool and the result shows inline. If you selected inside a text box (an email, comment, post, or document), the rewritten text is placed back exactly where it was — with full undo support (Ctrl/Cmd+Z). THE TOOLS • Humanizer — rewrite stiff, robotic-sounding drafts into natural, human prose. Ten tone modes: casual, academic, professional, friendly, concise, blog, email, marketing, storytelling, and more. • AI Detector — see how AI-flavored a text reads, with a probability score and flagged phrases. Detection is probabilistic — treat scores as guidance, not proof. • Paraphraser — reword essays, emails, and posts in six styles: standard, formal, casual, creative, shorter, or expanded. • Summarizer — condense long text into a tight TL;DR, bullet points, or key takeaways. • Grammar Fix — catch spelling, punctuation, and fluency issues with a clean list of every change. THREE WAYS TO USE IT 1. Selection button — select text on any page and click the Humanit pill. 2. Side panel — a full editor with tone modes, sample text, and results side by side. 3. Right-click menu — send any selection straight to a tool. FREE TO TRY One free run per day as a guest, three per day with a free account, and affordable word pools for heavy use. Your account and quota are shared with humanit.app — same tools, same quality, one balance. PRIVACY FIRST Your text is processed only when you explicitly run a tool — nothing is read, collected, or sent in the background. The extension communicates only with humanit.app and our authentication service. No ads, no browsing tracking, no selling data.
