At a glance

The brief, up front.

Problem

Deposition review loses behavioral signals when teams work from transcripts, and partners cannot attend every first read.

What we built

A multimodal platform on Aletheia and Thalamus that reads video, audio, and transcript as one record.

The challenge

What stood in the way.

Deposition review is one of litigation's most resource-intensive tasks. Even skilled reviewers process video one moment at a time, and a modern matter can involve dozens of hours of testimony. Partners set the analytical standard but cannot attend every first read, particularly the early-case reviews where litigation strategy gets shaped. The result: inconsistent quality across matters, days of associate time spent on manual review, and behavioral signals lost entirely when working from transcripts alone.

What we built

The system we shipped.

Levitate built Cognition Legal from the ground up as a multimodal AI platform. At its core is Aletheia, our proprietary behavioral intelligence engine, processing deposition video, audio, and transcript as a unified record: behavioral analysis, sentiment analysis, and AI-produced transcripts from a single upload.

Thalamus powers the AI chat layer: attorneys query the full deposition in natural language, with every response cited to the verified transcript and timestamp-linked to the corresponding video segment. Attorneys can define the strategic objectives a deposition was intended to address, and the platform tracks coverage, reporting what was established and what remains open.

What was delivered

Outcomes you can point to.

  • Multimodal deposition analysis: video, audio, and transcript processed as a unified record
  • Behavioral and sentiment intelligence with severity-graded flags across the synchronized timeline
  • AI-generated diarized transcripts with speaker identification and frame-accurate video sync
  • Conversational Q&A with every response cited to the transcript and timestamp-linked to video
  • Deposition goals management with automated coverage tracking and gap reporting
  • Court-ready exports from a single upload: litigation brief, case update, and discovery memo
