Margen - AI Editor for Google Docs

About

Margen reviews Google Docs and creates native comments directly in the document. Choose a persona such as Clarity, Grammar, Professor, Story, Poet, Sales, Social, or Custom, then ask Margen for the exact kind of feedback you want.

Margen is built for writers, students, editors, founders, and professionals who want useful editorial feedback without copying their work into a separate chat window.

Core features:
- Native Google Docs comments
- Custom prompt-first review mode
- Editorial personas for common review styles
- Full-document review from a floating toolbar
- Comment automation progress overlay with cancel control
- Account-based usage limits and billing

Margen only uses document text to generate the requested feedback. It does not sell user data or train models on user documents.
