Scans text against billions of web pages and academic databases for accidental plagiarism, detects AI-generated passages, and logs transparent document provenance via Authorship reports in Google Docs and Word.

RewriteBar captures the selected text system-wide and pastes the improved version back, so it functions in Chrome, Google Docs, Word, Slack, Notion, VS Code, email clients and more.
Use built-in commands such as fix grammar, simplify, humanize, summarise, title case, fix JSON, create ASCII art or translate, or author your own commands with variables and prompt libraries.
Combine several actions to transform text step by step — for example expand, add emojis, translate and rewrite a title in one flow.
Bring your own API key from major providers, use the RewriteBar Gateway, or keep everything on-device with Ollama, LM Studio, oMLX or Apple Intelligence.
