The Tour

The whole record, every angle.

Each view is a different read of the same source of truth: signal, citation, chronology, behavior, structure, and strategy. Cognition reads them all from a single deposition.

Multimodal
cognitionlegal.app / Flagged Moments
Flagged Moments: prioritized list of behavioral and verbal signals surfaced from the deposition, with High/Medium severity counts and category breakdowns.

The moments that decide the case, surfaced.

What an experienced litigator catches on careful review, surfaced automatically and ranked by impact. Each flag is grounded in the source record, so review starts from a triage list rather than a blank page.

  • Five signal categories, each with a defined detection signature
  • Prioritized High / Medium / Low with quantified confidence
  • Every flag links to its source: line, timestamp, and frame when available
Ask Depo AI
cognitionlegal.app / Ask Depo AI
Ask Depo AI: chat interface returning answers with transcript quotes, page-line citations, and timestamps into the source video.

Ask anything. Get a citation.

A natural-language interface to the entire deposition record. "Where did the witness get defensive?" returns the actual moments, each one quoted from the transcript, page-line referenced, with a timestamp into the source video.

  • Every answer cites page, line, and timestamp
  • Quoted excerpts open the synced viewer at the exact frame
  • Send any finding straight to a Litigation Brief, Case Update, or Discovery Memo
  • Built for trial work: verifiable evidence, not optimistic summaries
Behavioral
cognitionlegal.app / Sentiment Analysis
Sentiment Analysis: tone-tracked ribbon across the deposition with quantified Key Emotional Shifts and triggers.

Where the witness turned.

The full sentiment ribbon of the deposition, second by second, across positive, neutral, and negative tone. Below it, the Key Emotional Shifts: the specific moments where demeanor changed, the magnitude, and what triggered them.

  • Tone-tracked across the entire reel
  • Quantified shifts with directional scores
  • Each shift tied to a transcript moment and video frame
Strategy
cognitionlegal.app / Deposition Goals
Deposition Goals: strategic objectives defined against a loaded deposition, with auto-linked transcript segments and a coverage summary.

Strategy, made visible.

Once a deposition is loaded, add the objectives it was meant to answer. Cognition reads the full transcript, links every segment that addresses each goal, summarizes what was actually said, and tells you which objectives weren't covered. "6 of 7 covered" stops being a feeling.

  • Goals defined against any loaded deposition
  • Cognition auto-links every segment that addresses each goal
  • Coverage summary identifies what was established and what wasn't
  • Upcoming Cognition-inferred goals read directly from the questioning pattern, alongside any you define
Entities
Upcoming
cognitionlegal.app / Relationship Map
Relationship Map: parties, counsel, deponent, and exhibits laid out as a graph with dashed lines marking contradictions between testimony and exhibits.

The case, as a graph.

Every party, deponent, counsel, entity, and exhibit named in the deposition, laid out as a network with the relationships between them. Contradictions between testimony and the exhibits that controvert it surface as dashed lines, so the structure of the case is legible at a glance instead of buried in pages.

  • Parties, counsel, deponents, organizations, and exhibits as a single graph
  • Dashed lines connect testimony to controverting exhibits
  • Click any node to open its transcript references and source citations
Reports
Upcoming
cognitionlegal.app / Export Report
Export Report: choose-audience picker offering Litigation Brief for the internal team, Case Update for the client, or Discovery Memo for opposing counsel.

Same case. Three reports.

One deposition produces three deliverables, each written for the audience that's reading it. The internal team gets the full analysis. The client gets a plain-language update. Opposing counsel gets a formal memo. No copy-paste between drafts, no scrubbing of methodology.

  • Litigation Brief: for the internal team. Full analysis with AI annotations, sentiment, contradictions, and the annotated transcript.
  • Case Update: for the client. Two-page executive summary in plain language with key findings and next steps.
  • Discovery Memo: for opposing counsel. Formal memo with contradictions cited to the transcript, no AI methodology disclosed.
Exhibits
Upcoming
cognitionlegal.app / Exhibits
Unified Exhibits tab showing preloaded deposition exhibits alongside counsel-added records like travel logs and billing statements, each linked to its page-line citation in the transcript, with a chat panel returning answers cited to both the exhibit and the testimony.

Every exhibit, cited to the line.

Exhibits often decide cases as much as testimony does, but they're usually tracked separately from it. Cognition keeps the documentary record next to the testimony it speaks to, growing with the case as more comes in.

  • Opens preloaded with every exhibit referenced in the deposition, indexed by page and line.
  • Add external records into the same tab: travel logs, billing, prior statements.
  • Every exhibit, preloaded or added, links to the testimony it contradicts or confirms.
  • Chat across the full set with citations to both the document and the page-line.
Reconstruction
Upcoming
cognitionlegal.app / Event Timeline
Event Timeline: case chronology reconstructed from testimony, with conflicts between two events flagged inline.

The case chronology, reconstructed.

Cognition extracts every event from the testimony and arranges the chronology. Conflicts where two events can't both hold get flagged inline on the timeline. Broader contradictions, statement against statement or testimony against exhibit, are gathered in the dedicated Contradictions view.

  • Events reconstructed with date, actor, and transcript reference
  • Conflicts between two events flagged inline on the timeline
  • Every event opens its source segment
Impeachment
Upcoming
cognitionlegal.app / Contradictions
Contradictions: paired statements grouped by self, record, and cross-witness, with page-line cites and Bates IDs.

The record, paired and cited.

Every conflict in the record surfaces here, paired side by side and cited to the line. Cognition cross-references every answer against every other answer, every exhibit, every prior sworn statement. Self against self. Testimony against the documents. Witness against witness. The kind of impeachment a partner catches on the fourth read of a cold transcript, surfaced on the first.

  • Three groups: self conflicts, record conflicts, cross-witness conflicts
  • Every card pairs two statements with page:line cites, Bates IDs, and a status of Verified, Probable, or Flagged for review
  • Keep, dismiss, or flag any card, write a note, and send it to designations or the brief in one click
Structure
Upcoming
cognitionlegal.app / Topic Summaries
Topic Summaries: testimony partitioned into discrete topics with AI-written summaries and an Export PDF action.

The deposition, indexed.

A deposition is rarely about one thing. It's about ten things, across fifty digressions. Cognition partitions the testimony into discrete topics, writes a summary for each, and exports the whole index as a prep-ready PDF.

  • Topic partitioning with AI-written summaries
  • One-click PDF export for prep memos and co-counsel
  • Each topic links to the source transcript range
