Humanize AI-sounding text into natural, human writing, and check any text for AI. In Google Docs and 18 languages. By BookFoundry. Check if your writing reads as AI-generated, then refine it to sound natural and human. Right where you write, in 18 languages, in one click. BookFoundry is an AI detector and humanizer for writers, students, professionals, and anyone who wants their words to read as their own. Paste or select any text, see a clear AI-likelihood score, and refine it so it reads more naturally. No new tab, no copy-and-paste dance, no learning curve. WHAT YOU CAN DO • Detect AI writing instantly. Select text on any website, or paste it into the popup, and get an honest AI-likelihood score with a clear Human / Borderline / Likely AI verdict. • Humanize in one click. Turn stiff, AI-sounding text into natural, human writing that flows the way a person actually writes. See the before and after side by side. • Choose your voice. Pick a tone (Auto, Casual, Professional, Academic, or Creative) and set the strength, from a light polish to a full rewrite. The result adapts to how you want to sound. • Work right inside Google Docs. Open the BookFoundry panel, check your document or a selection, and replace it in place without leaving your page. • Write in 18 languages. English, Arabic, Spanish, French, German, Italian, Portuguese, Dutch, Polish, Russian, Turkish, Swedish, Danish, Norwegian, Finnish, Chinese, Japanese, and Korean. Full right-to-left support for Arabic. • Keep your flow. A clean, fast popup. Free checks every day. Your account and credits sync with your BookFoundry dashboard. HOW IT WORKS 1. Select any text on a page, or paste it into the BookFoundry popup. 2. Click Check writing to see how human (or AI) it reads. 3. Click Refine and humanize to rewrite it naturally. Pick your tone and strength first if you like. 4. The new text appears in a clear before-and-after view and is copied to your clipboard, ready to use anywhere. WHO IT IS FOR • Students and academics who want their essays and papers to read as their own work and meet their institution's standards. • Writers, bloggers, and content creators polishing drafts into clean, natural prose. • Professionals refining emails, reports, proposals, and posts so they sound human, not machine-made. • Non-English writers who are underserved by English-only tools. BookFoundry detects and humanizes natively in 18 languages. WHY BOOKFOUNDRY Most AI tools are English-only and stop at a single score. BookFoundry gives you an honest detector, a real humanizer with tone and strength controls, native support for 18 languages, and a panel that works right inside Google Docs. It is built by BookFoundry.AI, the platform that helps people write and publish full books, so the writing engine behind this extension is the same one trusted to produce publish-ready manuscripts. PRICING • Free AI checks every day, no account needed to try it. • Sign in with your BookFoundry account (Google, Microsoft, or email) to use your credits for unlimited checks and humanizing. • Top up anytime. The same balance powers your BookFoundry dashboard. PRIVACY • Text you check or humanize is sent securely over HTTPS to the BookFoundry service to produce your result, and is not sold. • The extension only reads the text you select or paste. It does not track your browsing. • Read the full policy at https://bookfoundry.ai/extension-privacy RESPONSIBLE USE BookFoundry is a self-check tool to help you improve your own writing and make it read more naturally.
