# Reproof

> Reproof (Reproof app or Reproof.app) is a writing app for drafting, writing, rewriting, and revising until you're ready to publish your writing. Free forever for 10 documents; Pro is $10/month or $99/year for unlimited documents.

Reproof helps writers keep the full writing process in one place—drafting, paragraph versions, clippings, collaboration, and revision—without bouncing between apps. Reproof's core features include paragraph versions to swap between different takes and see how they read in context, clippings to save cut bits of text for later, side-by-side editing to work on two documents simultaneously with find and replace between both documents, equal-class markdown and rich text support, full-library import and export in Markdown, Word, HTML, and PDF formats, and AI-powered proofreading to catch common mistakes before publication.

Reproof is built by Matthew Guay.
