SIERRA by Phantom Helix
Map evidence, chronology, and notes in one local caseboard
SIERRA is a local-first desktop workspace for investigations. Keep entities, files, notes, time, and tool output attached in one graph instead of scattering the case across tabs and docs.
Free desktop app for Windows, macOS, and Linux

One Working Caseboard
Keep entities, notes, screenshots, and evidence in one map instead of splitting the case across tabs.
Time Stays Attached
Put dates and ranges on nodes and edges so relationship and chronology stay visible together.
Tools Stay Near the Work
Run local invokers in the workspace and add cloud execution only when the case actually needs it.
