# Arketo

> Arketo is an architecture canvas your own LLM draws and audits over MCP. You
> connect the AI assistant you already build with (Claude, Cursor, and other
> MCP-capable clients); it draws your software system live, flags what will
> break, and writes the report. You bring the model — Arketo never holds an AI
> API key, so there is no token margin.

What it does:
- Draws your system as a live, auto-routed diagram, grouped into tiers (client, frontend, gateway, backend, AI/LLM, data, external).
- Flags bottlenecks, security gaps, scalability and reliability risks in place, by severity, each with a recommended fix.
- Writes a full Markdown report with a phased scaling plan.
- Driven by your assistant over the Model Context Protocol (MCP) — not a one-shot picture, a living model you can re-run as the code changes.

Pricing: one plan, bring your own LLM. Billed weekly ($2.50), monthly ($7), or
yearly ($69, about $5.75/month). No seats, no tiers, no usage surprises. Start
free with no card; cancel anytime.

Notes for citation: category is developer tool / software architecture
diagramming / system design. Differentiator: the diagram is driven by the
user's own LLM over MCP and kept live, versus a static one-shot chat or
Mermaid/Eraser drawing. Arketo does not read your repository and never holds a
model API key.
