Stage 02 · Discovery

Review it all, on the clock.

Hundreds of hours of footage and thousands of pages, reviewed in hours.

  • Ask plain-language questions across the entire file
  • Build a cited timeline of the case in minutes
  • Nothing sits unwatched on hour 80 of the footage
Stage 03 · Trial

Walk in on solid ground.

Every fact you rely on traces back to the evidence it came from.

  • Pull every statement from a witness across all interviews
  • Cited summaries you can check line by line
  • Find the moment, jump straight to the source
Trust, and verify

One click from AI findings to admissible evidence.

Longeye is built so every answer carries a citation. Click it and you land on the exact line of the transcript, second of the video, or row of the spreadsheet it came from.

You verify before you rely on it, and the record is right there when the finding is questioned.

  • One click from any statement to the underlying evidence
  • Summaries and timelines you can audit line by line
  • A full log of every query run against the file

By early 2026, Longeye had worked through 25 million files across 35 agencies, turning roughly 34 years of detective work into a few months.
