Arch-lab makes architecture diagrams you can talk through

A browser-based editor turns plain-text C4 and sequence diagrams into interactive, presentable views, with read-only MCP tools for AI agents.

Why it surfaced

Arch-lab treats architecture documentation as a text file rather than a picture: diagrams can be diffed, reviewed, committed, and exported, while an agent can write them against the real parser and receive validation. The promise of a diagram that keeps up with a conversation is unusually concrete here—click into a sequence message, drill into a C4 box, or take the whole view immersive.
