You talk, it listens, and a diagram evolves in real-time. It auto-detects the best diagram type (flowchart, sequence, mindmap, timeline, ER, state, class) or you can pick one manually. A 3-step LLM pipeline runs every minute to classify the conversation, extract structure, and generate Mermaid daigrams, building on the previous version each cycle.

You can also bring your own provider and API key (OpenAI, Anthropic, Ollama) for higher quality diagram generation while keeping transcription fully local.

I built this because I found myself frequently wanting to diagram what we're talking about in work meetings at my day job. Please give it a look and let me know what you think!

P.S. The name is inspired by "shimmer" being a collective noun for a group of mermaids.

I have been working with python for over 10 years and have standardized my workflow to only use pip & setuptools for all dependency management and packaging [1]. It works great as a vanilla setup and is 100% standards based. I think uv and similar tools mostly shine when you have massive codebases.
