Every's founders launch Proof, a collaborative markdown editor designed for humans and AI agents to work together in real-time. The episode explores how Proof evolved from a provenance-tracking tool into a lightweight document platform that has transformed how the Every team collaborates with AI agents like Claude, enabling a new workflow where humans and agents can co-author, comment, and iterate on documents seamlessly.

Key takeaways

• Agent-native products don't require agents built into the tool itself; they can be designed so external agents (like Claude) can seamlessly integrate and collaborate alongside humans.
• The key insight of Proof is that text is cheap to produce, so the workflow should prioritize rapid ideation, agent-assisted drafting, and human refinement rather than trying to track every word's origin.
• Collaboration between humans and agents works best when there's a canonical document that humans control, with agents creating alternative versions that can be selectively integrated rather than agents freely editing the main document.
• Creating good plans upfront with agents produces exponentially better results than asking agents to execute vaguely defined tasks—Proof serves as the ideal space to collaboratively build these plans before execution.
• Not all writing benefits equally from AI; information-dense documents (technical specs, summaries, logs) are better read and processed by agents, while creative and personal writing (essays, stories) should remain human-focused.
• The simplicity and low friction of Proof—no login required, just paste a link for agents to access—has proven more valuable than complex features, making it ideal as an open-source component for other builders.

"Brandon set up these Notion agents which helped us for anyone who was running a business inside of Every you get interviewed by an agent and then it turns that into a 2026 plan doc."

Claude uses

"I can copy that link and post and give it to my Claude R2 and I can say I'm recording a podcast. Can you fill in an agenda?"

Codex uses

"I had Codex write a proof doc about exploring the idea of adding a dashboard to proof. I literally can write CSS and HTML. So I like basically went back and forth with Codex a bunch."
