It's fast, free, and open source—available now at http://proofeditor.ai.\n\nIt’s built from the ground up for the kinds of documents agents are increasingly writing: bug reports, PRDs, implementation plans, research briefs, copy audits, strategy docs, memos, and proposals.  \n\nWhy Proof?\nWhen everyone on your team is working with agents, there's suddenly a ton of AI-generated text flying around—planning docs, strategy memos, session recaps. But the current process for collaborating and iterating on agent-generated writing is…weirdly primitive. \n\nIt mostly takes place in Markdown files on your laptop, which makes it reminiscent of document editing in 1999.  \n\nProof lets you leave .md files behind.\n\nWhat makes Proof different?\n\n- Proof is agent-native: Anything you can do in Proof, your agent can do just as easily. \n\n- Proof tracks provenance: A colored rail on the left side of every document tracks who wrote what. Green means human, Purple means AI. \n\n- Proof is login-free and open source: This is because we want Proof to be your agent's favorite document editor.\n\nCheck it out now, for free—no login required:\n\nhttps://proofeditor.ai","author":{"name":"Dan Shipper 📧","username":"danshipper","avatarUrl":"https://pbs.twimg.com/profile_images/1946219091305340928/_Ef-eDlc_200x200.jpg"},"createdAt":"Wed Mar 11 18:14:02 +0000 2026","engagement":{"replies":123,"retweets":101,"likes":1500,"views":587937},"media":{"photos":[],"videos":[{"url":"https://video.twimg.com/amplify_video/2031795739656085504/vid/avc1/1714x1080/jQMay5YZho5gGgib.mp4?tag=21","thumbnailUrl":"https://pbs.twimg.com/amplify_video_thumb/2031795739656085504/img/ZfMLZvp-P0azKimi.jpg","width":1714,"height":1080,"duration":5.933}]},"externalLink":{"url":"http://proofeditor.ai","displayUrl":"proofeditor.ai","title":"Your Agent","description":"Proof is an online document editor built for agents and humans to collaborate.
