Composer is a real-time, multiplayer markdown editor where people and agents can work side-by-side. Instantly share markdown generated by your agent with teammates, edit in real time, leave comments, suggestions, and share context. Your agents join as true collaborators, working directly alongside you and your team.

Hey Product Hunt 👋 I’m Jesse, co-founder of Composer.
Agentic workflows today are mostly focused on written documents. These same workflows also feel like they are mostly solitary. The hard part isn't writing a document, it's shaping it *together*. Our agents write everything, including the wrong things. Then, when you’re ready to share what you’ve done with others, you have to copy results over to a shared space, sending screenshots, committing to a repository, or chatting about what you did. There’s no straightforward way for people and agents to work together in real-time.
That’s why we created Composer.
How it works:
- Composer is all Markdown under the hood.
- Markdown docs can be shared directly from your coding agent session.
- Agents have full document access via MCP and can reply to comments and post suggestions.
- Supports real-time collaboration and access controls with both people and agents. Document versioning is coming soon!
Here’s how teams are already using Composer:
- Quickly shape a plan together before you start implementation.
- Use comments and suggestions to quickly iterate with your agent on document content.
- Easily share and collaborate in Markdown without losing shared context.

We can't wait to hear your feedback! We're working hard to iteratively polish the product and your perspectives will help us make Composer the best it can be.
Let us know what you think!

@nottil The idea of agents becoming actual collaborators instead of just content generators is really interesting. How do you handle conflicts when multiple people and multiple agents are editing the same document at the same time?

@nottil @nicole_hynek Hey Nicole! Technical co-founder here. We use CRDT data structures behind the scenes to ensure the latest changes are seamlessly merged in real time. This applies to both human and agent collaborators via MCP.
