A “murderboard” is just a mind map that doesn’t lie. Muuurder is built for speed, clarity, and dense webs of relationships.
Create cards, edit fast, add attributes, timestamps, and types. Keep the board dense without turning it into spaghetti.
Connections can be typed + labeled, and you can even model conditional display logic when you need “if/then” structure.
Classic board view for precision. Sphere/3D view for exploring your web from a different angle.
Use the tool for free. Create a cloud account when you want your boards to persist, travel, and collaborate.
Perfect for quick thinking, drafting, and single-session obsession.
For serious projects: saving, sharing, and collaboration.
If it has entities + relationships, it belongs on a board.
Characters, motives, timelines, plot logic, clues, red herrings, worldbuilding, lore continuity.
Sources, claims, contradictions, provenance, evidence webs, interview notes, and “what’s missing?”
Product discovery, incident analysis, stakeholder maps, investigations, planning, and collaborative thinking.
