System Design Assistant
Your AI co-architect — interactive system design, diagrams, ADRs, and tradeoff analysis grounded in your codebase.
“An AI co-architect that designs with you — diagrams, ADRs, and tradeoffs, grounded in your real code.”
Role in the platform
A grounded module. Reuses Codebase Intelligence (#2) for grounding; ships as a ContextOS module plus a standalone interview-prep product.
Overview
An assistant that helps engineers design systems: generate and iterate on architecture diagrams (Mermaid/diagram-as-code), produce ADRs, reason about tradeoffs (scaling, consistency, cost), and — uniquely — ground designs in the actual codebase via Codebase Intelligence (#2).
Plus a prosumer interview-prep mode: practice system-design interviews with an AI interviewer/coach.
The problem
System design is high-stakes, under-tooled, and AI-assistable. Generic chatbots give unstructured advice with no persistence; diagram tools don't reason.
Grounding design in real code, not generic patterns, is the differentiator.
What it is
Pose a design problem; optionally ground it in your codebase (#2), reason through tradeoffs and options, and emit a Mermaid diagram + an ADR + a tradeoff analysis — then persist it as design memory you can iterate on.
Two distinct revenue pools — enterprise architecture and interview prep — de-risk it.
Key features

Why it's different
- Codebase-grounded design, not generic patterns.
- Structured, persistent output (diagrams + ADRs + tradeoffs) versus a chat transcript.
- Two markets de-risk it: enterprise architecture and interview prep.
