“Longeye has already proven its value, cutting months off of investigations, surfacing leads we might have missed, and even closing gaps in a cold-case homicide. Every hour Longeye gives back to my detectives is an hour invested in solving cases, supporting victims, providing closure and strengthening community trust.”

  • Overlay GPS, call records, and plate reads at once
  • Timeline slider across thousands of points
  • Raw coordinates resolved to street addresses

Follow the money. Surface the pattern.

Drop in a spreadsheet of bank records, tolls, or commissary logs and ask in plain English. Longeye reads it natively and hands back the chart, the table, or the pattern, no formulas, no manual sorting. Ask for any chart of any data, and combine multiple spreadsheets into a single analysis.

  • Charts and summaries from plain-language questions
  • Cross-reference transactions against the rest of the case
