Catch the Contradiction While the Witness Is Still Talking
During a deposition — in the room, from a recording, or over Zoom, Teams, or Meet — ProvaLens listens in real time and flags possible admissions, conflicts and follow-up questions, and the conflicts against your case file. Each one cited to a timestamp and speaker, so you can act on it before the witness moves on.
For any civil litigator — business, real-estate, employment, family, bankruptcy, and PI.
The Best Follow-Up Is the One You Ask in the Moment
You already know the file. But a witness can say something that quietly contradicts the contract on page 12, or the answer they gave in a prior deposition — and three questions later, the moment's gone. Reconciling live testimony against the whole case file, in real time, is more than any one person can hold in their head while they're also running the questioning.
Live Cross Copilot does that watching for you. It is capacity, not substitution — the copilot surfaces and cites; your litigator decides which question to ask, and always verifies against the certified transcript. The court reporter's transcript governs; this is leverage for the attorney holding the floor.
From Live Testimony to Cited Leverage in Three Steps
No plugins for browser-tab meetings, no new workflow. Start the session and ProvaLens works the rest of the matter alongside you.
Start a Live Session
Use a microphone in the room, play a recording, or share the audio of a Zoom, Teams, or Meet deposition through your browser. Remote capture mixes the meeting audio with your mic — no plugins or drivers to install.
Watch the Cited Stream
The transcript scrolls in real time, and suggestions stream alongside it — admissions, contradictions, follow-up questions, and conflicts against your case file — each one cited to a timestamp and speaker you can confirm on the spot.
Save to the Matter
When you're done, save the session to the case. The recording and transcript become documents that feed your timeline, contradiction reports, and the case-file checks for your next deposition — the work compounds.
What It Surfaces — As It's Said
Four kinds of cards stream as the testimony unfolds. Every one points to a timestamp and speaker so you can confirm it before you decide what to ask — and verify it later against the certified transcript.
Admissions
The favorable concession the witness just made — flagged and cited, so you can lock it in before the moment passes.
Internal Contradictions
Where the live testimony conflicts with itself — flagged with the timestamp:speaker on each side, so you can impeach with their own words.
Follow-Up Questions
Suggested lines worth pursuing while the door is open — a prompt, not a script. Your litigator decides which to ask.
Conflicts Against Your Case File
Where the live answer conflicts with the contract, the prior depositions, or the expert reports already in the matter — cited to both the testimony and the document.
Checked Against the Whole File
Every card points to a source you can open and confirm. A few of the kinds of things it surfaces, live:
"[01:14:22 — Witness] just testified the contract was never signed — conflicts with the executed copy in their own production."
"[00:42:09 — Witness] answer contradicts [00:18:51 — Witness] earlier in this session."
"Admission: witness conceded no direct knowledge of the events — consider locking it in now. [00:55:30 — Witness]"
"Follow-up: the damages timeline still hasn't been established on the record — worth pinning down here."
Illustrative examples. Suggestions depend on the testimony and the contents of your own case file. Always verify against the certified transcript.
Live Trial Mode: Flag Possible Conflicts With Their Own Deposition
Same live engine, a different moment. Put a witness on the stand and switch Live Cross into Trial mode: ProvaLens checks what they're saying right now against what they swore to at their own deposition — not the whole case file, just their own prior testimony — and flags it the moment it conflicts.
Checked Against Their Own Words
Retrieval is scoped to that one witness's own prior testimony — not a general search of the file — so what is flagged is a possible self-contradiction, not a stretch.
Page:Line Cited, Every Time
Each conflict is tied to the exact page and line of the prior transcript. A citation that doesn't match a real line in the deposition is dropped — never shown.
A Question Ready to Ask
Alongside the conflict, ProvaLens builds the impeachment question — "Isn't it true that on page X, line Y, you testified …?" — ready for you to ask or adapt.
Same discipline as the rest of Live Cross Copilot: the copilot surfaces and cites, your litigator decides which question to ask, and the certified transcript governs.
They Stop at the Transcript. We Catch It as It's Said.
Post-hoc tools start working after the deposition ends — you read the summary the next morning, when the witness is gone and the questions you wish you'd asked are gone with them. Live Cross Copilot watches the live testimony against your whole case file while it's happening, so a possible conflict is flagged while you can still do something about it. The window to follow up closes fast; this keeps it open.
Live, Not After the Fact
Suggestions stream as the witness speaks — not in a report you read once the deposition's over and the chance to follow up has passed.
Checked Against the Case File
Live answers are reconciled against the contract, prior depositions, and expert reports already in the matter — not just against the words spoken today.
Cited, Attorney in Control
Every card cites a timestamp and speaker. The copilot surfaces and cites; your litigator decides which question to ask. The court reporter's transcript governs.

Common Questions
Does Live Cross Copilot replace the court reporter or the official transcript?
No. Live Cross Copilot is a preparation and leverage tool for the questioning attorney — not a transcription or record product. The court reporter's certified transcript governs. ProvaLens surfaces and cites in real time so you can act on what you hear, but you should always verify against the certified transcript.
How does it capture a Zoom, Teams, or Meet deposition?
For browser-tab meetings, Live Cross Copilot uses your browser's built-in screen-share to capture the meeting audio, mixed with your microphone. There are no plugins or drivers to install. You can also point it at a microphone in the room or at a recording.
Is every suggestion cited?
Yes. Admissions, contradictions, follow-up questions, and conflicts against the case file are each tied to a timestamp and speaker reference so you can confirm them in the moment. The copilot surfaces and cites; your litigator decides which question to ask — and always verify against the certified transcript.
Do I need to follow consent or recording rules?
Yes. Recording and capturing testimony are governed by the rules of your jurisdiction and the deposition's ground rules. You are responsible for obtaining any required consent and following the applicable rules before capturing a session. Live Cross Copilot is a tool you control.
Why not just run a live deposition through ChatGPT?
A live deposition is privileged work product. Capturing it is exactly why you use lawyer-grade AI that is built for HIPAA workflows, signs a Business Associate Agreement, and never trains on your firm's data — not a consumer chatbot. ProvaLens also reads the matter's whole case file, so the live testimony is checked against the contract, prior depositions, and expert reports.
How much does it cost?
Live Cross Copilot is included in the ProvaLens Practice tier at $499 per month — one flat price for your whole firm, not per seat. See the pricing page for all tiers.
How is Live Trial Mode different from Live Cross at a deposition?
Same real-time engine and the same session, switched to a different comparison. At a deposition, Live Cross checks testimony against your whole case file. In Live Trial mode, it checks a witness's live testimony against that same witness's own prior deposition — the classic impeachment comparison — and cites the exact page and line where they said otherwise.
