FirstHand reconstructs real-world events from photos, video, witness accounts, maps, and open-source evidence.
Place every camera. Synchronize every angle. Rebuild the timeline. Compare what changed before and after. Then trace every conclusion back to the evidence that supports it.
Reconstruct the Event
FirstHand brings scattered evidence into one interactive workspace.
Plot photos and videos on a 3D map. Determine where each camera was located and what direction it was facing. Synchronize multiple videos to a shared event clock. Mark important moments and watch the event unfold across every available viewpoint.
See It From Every Angle
Click any camera on the map to see what it could see.
Compare several cameras side by side. Isolate the views that matter. Scrub through time frame by frame. Tag moments manually or let AI identify possible matches across multiple sources.
When the same flash, sound, vehicle, or movement appears in different recordings, FirstHand can help align them to the same moment.
Understand What Changed
Compare imagery from before and after an event directly on the map.
Swipe between dates, flip back and forth, move around the scene in 3D, or examine the environment from a reconstructed camera position.
AI That Works With the Evidence
Ask FirstHand questions while you investigate.
Find additional evidence. Identify landmarks. Compare viewpoints. Locate important moments. Detect contradictions. Suggest synchronization points. Explain why a camera was placed where it was.
AI assists the investigation without hiding the reasoning behind it.
Evidence, Not Just Answers
Every observation can retain its source, time, location, confidence, and history.
AI suggestions remain distinguishable from human conclusions. Corrections do not erase earlier work. Findings can be reviewed, challenged, and traced back to the underlying evidence.
From Evidence to Reconstruction
Investigate. Reconstruct. Verify. Publish.
FirstHand turns disconnected media into a spatial and temporal reconstruction of what happened.
