Splat
Splat is a lightweight, open-source tool for visually clustering ideas and insights. It runs entirely in your browser from a single HTML file — fast, local, and private, with optional AI assistance.
Open a single HTML file and start clustering notes immediately. No installs, no accounts required.
Your data stays in the browser by default. Use AI features only if and when you choose.
Drag, group, color-code, and reorganize notes to surface themes and patterns in qualitative data.
Search notes semantically, highlight concepts, and perform bulk edits with natural language commands.
Ideal for UX research, brainstorming, interviews, and collaborative synthesis sessions.
Free and extensible under GPL-3.0. Inspect, modify, and contribute to the codebase.
