Hi HN, I built a single-file, open-source affinity diagramming tool for qualitative analysis in the browser, called Splat. You can use it to cluster and organize notes on a board.
It runs entirely in the browser as a single HTML file:
– no install, no build step
– works offline
– optional semantic search with HF Transformers.js and AI assistant with Ollama (local) or OpenAI (for more power)
– JSON export/import for analysis elsewhere
I built Splat while manually clustering 1400+ notes of interview data for a research project. I wanted something I could email to collaborators and use and extend without worrying about accounts or bloat from proprietary services. We're using this internally in our research lab for affinity diagramming qualitative data.
Would love feedback, especially from people doing qual research, UX, or synthesis work. Feel free to build on or extend!
