SIERRA

SIERRA is a local-first desktop investigation workspace for OSINT, cyber, and research work.

Instead of scattering a case across notes, screenshots, tabs, and whiteboards, SIERRA lets you map entities, evidence, chronology, and tool output in one connected caseboard. Keep relationships visible, attach time directly to nodes and links, and run investigation tools close to the graph instead of jumping between separate apps.

• Build case graphs with notes, media, evidence, and links in one place
• Keep chronology attached to entities and relationships
• Run local invokers and optional cloud tools from inside the workspace
• Export diagrams for reporting or sharing, with privacy-friendly redaction options
• Works on Windows, macOS, and Linux

Built for investigators, analysts, researchers, and anyone working cases that need structure, context, and traceable connections.
