NOT REALLY
why this verdict
Keep paying — Anthropic has not replaced it
Anthropic's version overlaps, but does not finish the design job, so this one still earns its $10/mo.
- A named launch, not a vibe named, unlinked
- Models emit Mermaid diagrams from a prompt. Anthropic, January 1, 2025 — no announcement link recorded yet.
- How much of the job it covers not the job editorial call
- Parts of it. The job still needs the tool to get finished.
- Is there a free way to do it? yes
- 3 of 3 listed replacements have a usable free tier: Mermaid, Excalidraw and Lucidchart.
- What the call is worth $120/yr
- $10/mo at the entry paid tier — $120 a year per seat.

The backstory
Eraser turns a description or a repo into architecture and sequence diagrams that live next to the docs and update as code. A chatbot can emit Mermaid syntax, but keeping diagrams versioned, collaborative and attached to documentation is a workflow rather than an output.
