Moxn is a collaborative editor with git-like version control for documents and a filesystem interface for agents.

Even before AI, I wanted docs to behave more like repos for two reasons:

- With multiple users live-editing in the same doc, the content I was working on would bounce around in the UI.

- I'm naturally iterative and I don’t one-shot prose well.

Collaborating with AI added two more pain points:

- Multiple agents live-editing the same doc leads to clobbers and deadlocks or file replication and name-based versioning.

- Lack of granular agent-specific permissions.

The common options helped, but came with tradeoffs:

- Git + markdown works well for agents and individual work on a machine, but teams lose multiplayer editing.

- Notion and Google Docs work better for teams, but agents have to go through APIs that weren't designed for filesystem-style exploration. The versioning of the docs is revision-based, not branch-based, and search is flat.

Moxn is an attempt to combine the git + markdown and Notion/Google Docs worlds to support iterative development and collaboration on content.

For humans: a multimodal editor with comments, backlinks and real-time multiplayer. Humans can set branch and section-specific AI permissions.

For agents: a filesystem interface with `find`, `search` and `read` tools for content organized by paths, tags, and databases.

The part I care the most about is the version control. Docs have branches, commits and merge requests. Merges are common-ancestor aware and conflicts resolve at the section grain. Edits flow into the CRDT (Yjs/TipTap), get flushed to mutable draft records, and frozen on commit. Edits have `git staged` semantics and agents default to auto-commit.

I use different workflows for different types of work with Moxn.

- Coding: I push complex plans with Mermaid and bug reproductions with screenshots via Playwright to review and leave comments. I have a post-commit hook that runs Claude Code to auto-update docs on a branch with the same name as my code edits and create a changeset, which is a coordinated collection of merge requests.

- Content: I fan agents out on branches to propose candidates (still an MLE at heart), read the diffs, cherry-pick chunks that I like, drop into the editor to write and loop. The launch post https://moxn.dev/blog/launch was written that way.

Rough edges I want to call out:

- Editor cold-start and polish aren't at Notion/Obsidian levels yet.

- Full-text search only covers the default branch today, and doesn't hit metadata or multimodal content yet.

- No audit logging or other enterprise features yet.

There’s a free plan with no credit card required. The blog post has screenshots, and the docs have a video walkthrough including a Playwright bug reproduction doc.

I'd especially love feedback from anyone using agents against internal docs or knowledge bases who has hit retrieval, coordination or collaboration problems.
