the pirate's job is to move as fast as possible to develop valuable, shipped product features by vibe coding.
the architect's job is to turn the product surface discovered by the pirate into a reliable, structured machine—also by vibe coding, but at a slower, more well-reasoned pace.
every product needs a pirate but most product's only need an architect once they some form of PMF, and in that case they usually don't need one full-time. architects can work across many codebases and solve interesting technical challenges. pirates go hard on a product that they own end-to-end.
It’s a live collaborative document editor where humans and AI agents work together in the same doc. It's fast, free, and open source—available now at proofeditor.ai.
It’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.
Why Proof?
When 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.
It mostly takes place in Markdown files on your laptop, which makes it reminiscent of document editing in 1999.
Proof lets you leave .md files behind.
What makes Proof different?
- Proof is agent-native: Anything you can do in Proof, your agent can do just as easily.
- Proof tracks provenance: A colored rail on the left side of every document tracks who wrote what. Green means human, Purple means AI.
- Proof is login-free and open source: This is because we want Proof to be your agent's favorite document editor.
Proof is the most collaborative product we’ve ever built @every. It has commits from 5 team members, both technical and non: @bran_don_gell, @kieranklaassen, @naveennaidu_m, @bigwilliestyle, @lucas__crespo.
It is such an immense pleasure to work with this team, and it makes me so excited to make this product open source.
Let’s work together to make Proof as good as it can be:
I just showed the team our 2026 roadmap. I got so psyched that I wanted to share it with you too.
Here's our full 2026 strategy.
Every is built around three things:
Ideas. Apps. Training.
Everything connects to that mission. And this year, everything we build will connect to each other.
We run on a loop:
- Live in the future together.
- Write what we see.
- Build what's missing.
- Teach what works.
Writing is the engine. Force yourself to articulate what you're seeing, and you make that future visible to everyone else. Once you've named it, it's obvious what to build next.
i've been playing with it for a week or so and it's already my go-to model. it's fast, agentic, extremely smart, and has great vibes.
some of my top use cases:
- it flagged every single time I sidestepped conflict in my meeting transcripts
- it spun up a bite‑size ML course that it pings me about every morning
- it found a stroller brand from one blurry photo
- it coded a new custom AI benchmark in record time
- X‑rayed an Annie Dillard classic and found writing tricks I’d never noticed before
- it even analyzed @every’s org chart to tell me what we’ll be good at shipping, and what our weaknesses are
