Ultrahumanizer: AI Humanizer & Writing Tools

Use an AI humanizer to revise selected or pasted text, review changes, and apply the result where you write.

Revise a draft beside the page you are working on. Select a passage or paste your text into the side panel, choose a tone, and run the AI humanizer. Compare the original and revised text before using it. Copy the result, or replace a selection in a compatible text field and undo the change if needed. You can start from the right-click menu or Alt+Shift+H. A selection button is optional and enabled separately for each website. The same workspace also includes writing and content-review tools. Each keeps its own draft, and you choose when to run it and whether to use its output. Online processing is labeled before you run it. Submitted text and images are sent to UltraHumanizer and its processing provider, DeepSeek. Tools marked local keep their content on your device and send only usage metadata. Audio stays on your device. Selecting text or choosing a file alone does not upload it. A free account is required. Allowances are shared with the website; paid subscriptions provide higher limits. Your current allowance is shown in the extension. No API key is needed. Complex editors may require copy and paste. Review results for accuracy. Session drafts expire after 24 hours and clear when the browser closes. See the linked privacy policy for storage and processing details.
