Without Compromise
Claude can code up a designer's portfolio in thirty seconds. We still share our ideas as paragraphs and screenshots of Excalidraw — show, don't just tell. Rich Doc is where you bring the idea, your agent renders it, and your team responds.
The status quo is absurd.
When you want to explain a flow, a system, an idea, you have two options.
Easy to revise. Sacrifices everything visual. The reader builds the picture in their head and gets it wrong.
Open Excalidraw, or Figma, or GIMP. Screenshot. Paste. Iterate. Repeat.
Your agent could write the diagram itself — live, interactive, more expressive than Excalidraw was ever going to be. But to share it, we still flatten and freeze it into a JPEG.
We're using twenty-year-old document tools to share work an agent can make in twenty seconds.
You bring the ideas.
The agent brings the rest.
You're already co-authoring with an agent in Claude Code. You bring the ideas and content. The agent is your editor, your visual artist, and your copywriter, all at once.
Then you ask your agent to share it to Rich Doc. Your team opens a URL filled with rich, interactive elements — not a flat screenshot — and leaves feedback on it.
When you work through the feedback together, your agent reads each comment in context, sees the visual, rewrites the file, and shares the new version. The conversation carries over.
One place. One conversation. No friction.
Expressive means expressive.
Not boxes-and-arrows expressive. Not Mermaid-with-a-color-palette expressive. Each of these is a working thing on this page. Imagine these living inside your docs.
Interactive flows
Click a state. The diagram transitions. The reader is operating the flow, not reading about it.
Animated explanations
The idea builds itself on screen while you read the paragraph. Pause to think. Replay if you missed something.
Annotated diagrams
Hover any node and the explanation pops up right where you're looking. No legend to consult on the side.
Live charts
The chart is wired to the source. When the data moves, so does the chart, instead of you pasting last week's screenshot into the doc.
Embedded demos
A working toy sitting in the doc. The reader plays with it in place instead of clicking out to a separate sandbox.
The medium fits the idea. If the idea is interactive, the doc is interactive. If the idea has state, the doc has state. Docs become beautiful, informative, and native to the problem they're explaining.
Connect your agent.
Rich Doc works from the terminal and from clients that speak MCP. Install the CLI for local agents, connect MCP for cloud or desktop chat, tell your agent to share a doc, send a URL to your team.
- —No editor to learn.
- —No format to convert.
- —No new sharing model.
Your agent already speaks the medium.
Why not?
Google Docs
Visuals get flattened and frozen into a JPEG. Comments float beside the picture, never inside the part you meant.
Figma
Comments work fine. The visuals are gated behind weeks of tool-learning — most of your team can't contribute one.
Excalidraw + Mermaid
Only as detailed as your patience for boxes-and-arrows. Wrong tool the moment your idea has state, motion, or interaction.
Rich Doc is the medium for everything your agent can actually produce.
