Key Features
✓ Pros
- DiagramGPT generates architecture diagrams, sequence diagrams, ER diagrams, flow charts, and cloud diagrams from natural language — and gets the diagram *type* right, not just the content
- Document mode combines diagrams with markdown docs in a single canvas — your architecture decision records and their diagrams live together
- Code-aware — paste a schema or API spec and it generates the corresponding ER or sequence diagram
- Canvas mode for freeform whiteboarding when you need to sketch before formalizing
✗ Cons
- Free tier is extremely limited — 3 files, 5 AI diagram generations total
- Pricing jumps steeply from Starter ($15) to Business ($45) with usage-based overages on both
- No offline mode — web-only
- Less useful for non-technical diagrams (customer journey maps, org charts)
Full Review
Eraser's DiagramGPT is the strongest text-to-technical-diagram engine available. Type "microservices architecture with API gateway, three services, PostgreSQL, and Redis cache" and it generates a correctly-structured architecture diagram — not a flowchart pretending to be one, but an actual cloud architecture diagram with the right shapes, connections, and labels.
Engineering teams that create architecture and system design documentation. If your diagrams have services, databases, queues, and APIs in them, Eraser produces better AI output than anything else on this list.
