Legal professionals—especially paralegals who bill by the hour—know the drill: reviewing a single deposition transcript can take hours, even days. It’s tedious but necessary work, and yet it’s often the first thing attorneys or clients try to cut from the budget. For defense-side paralegals, meeting billable quotas while balancing heavy caseloads can feel like an impossible race.
What if you could automate the first pass?
With Microsoft Copilot, you can.
This post kicks off my 7-part blog series: “Powerful Ways Law Firms Can Use Microsoft Copilot—Responsibly.” And we’re starting with one of the most practical use cases in litigation: summarizing and analyzing deposition transcripts stored in OneDrive or SharePoint.
What Copilot Can Do
Microsoft Copilot can help you:
Summarize long transcripts quickly
Extract testimony relevant to specific legal issues (e.g., damages, liability, timeline)
Present the results in a clean, searchable table
Save time and reduce cognitive overload for your legal team
Whether you're prepping for depositions, mediation, or trial, Copilot gives you a faster way to locate what matters—without skipping the details.
Copilot in Action: Summarizing Deposition Transcripts
There are two ways to run the prompt:
✅ Option 1: SharePoint Copilot Agent
If your firm has Microsoft 365 Copilot and a SharePoint Agent scoped to a matter site or document library, you can ask the agent directly to summarize the PDF—no need to open or convert the file to Word.
✅ Option 2: Word Online via OneDrive
If you're not using a SharePoint agent, open the OCR-enabled PDF in Word Online. It will convert to editable text, where Copilot can run the prompt directly inside the document.
💡 Try This Prompt:
“Summarize the key testimony in this deposition transcript and extract all references to [insert topic, e.g., financial damages, timeline of events, medical treatment, etc.]. Present the output in a table format with the following columns: Page, Line, Testimony, Objections (if noted), and Notes. Be as concise as possible while preserving key context from the testimony.”
👉 Pro Tips for Input:
Upload or link the clean transcript text (PDF, DOCX, or pasted content into Word).
Make sure the document formatting is clean (e.g., page and line numbers are intact and easy to parse).
Save the transcript with date/time metadata: YYYYMMDD-FileName.pdf.
Example of What You’ll Get Back:
Page | Line | Testimony | Objections | Notes |
---|---|---|---|---|
32 | 12–22 | “The plaintiff stated she first noticed pain after the second injection…” | None | Describes onset of symptoms |
47 | 6–10 | “Dr. Smith acknowledged he did not review the full MRI report before making a diagnosis.” | Relevance | Potential credibility issue |
Ethical Tip: Don’t Skip the Human Review
Copilot is smart—but it's not a lawyer. Use it to jumpstart your review, not to replace your judgment. Always verify the output, compare against the original transcript, and add your notes and nuance before relying on the summary in a legal document. AI can miss nuance.

Whether you're a paralegal trying to meet billable expectations or a firm looking to reduce burnout without compromising quality, summarizing deposition transcripts with Copilot can be your behind-the-scenes assistant—when used ethically and strategically.
