Doc Analyser · Architecture intelligence

ArchMind

Turns project documents — RFP, BRD, HLD, LLD, API and DB designs — and the GitHub repositories that implement them into one evidence-backed knowledge model. It answers the question every architecture review asks: does the code do what the documents say?

  • Extracts requirements, roles and workflows with page-level evidence
  • Code ↔ document traceability, conflict and drift detection
  • Flow, sequence, ER, class and component diagrams plus a mind graph
  • Runs fully local — Ollama + pgvector, no external AI calls
