How long to summarize a deposition on Mac: real hours, costs and fixes for lawyers

How long does a deposition summary take?

The figure most people quote is 8 to 12 hours for a 3-hour deposition, done by a paralegal. It comes from a legal AI vendor's blog, and that vendor sells deposition analysis. The post cites no source for its numbers. We found no independent study that times deposition summaries. Use the range to plan, and treat it as a starting guess until you time your own work.

Turn transcript pages into hours

Start with the page count. Open the transcript, go to the last page, and write down the number. Then divide by a reading speed. The same paralegal blog gives 20 to 25 pages an hour as an industry average. That average has no named source, so measure your own speed on one section before you trust it.

Those hours cover reading and summarizing only. They leave out the slow parts. A transcript full of exhibits takes longer than a clean one. Objections, errata sheets and cross-talk add minutes on many pages. Add a buffer to your estimate, and say so in your plan.

Why the calendar takes longer than the work

A 10-hour job rarely fits into a busy day, so it waits in a queue. Most of the delay happens before anyone reads a line. The same blog puts standard transcript turnaround at 7 to 14 business days. A deposition taken on a Monday can sit for a week or longer before a reader opens the file.

Ask your court reporter about turnaround when you book. Ask what delivery options exist and what they cost. Options vary by reporter and by case, so confirm them before you set the summary date.

Mistakes that make summaries take longer

• Starting without a template. Every reader invents columns, so the draft gets rebuilt once it arrives.
• Reading the full transcript before writing a word. Write notes as you go, page by page.
• Summarizing from memory. Memory drifts, so check each entry against its page and line.
• Letting exhibits slip. Log each exhibit mention on the same row as the testimony that cites it.
• Passing the whole job to one reviewer. Split reading from checking so the second person can start sooner.

A simple template avoids most of these problems. Use columns for Page, Line, Topic, Testimony, Exhibit and Follow-up. Save it once in Word or Pages. Reuse it for every deposition, so the format never needs rebuilding.

What AI summary tools can and cannot promise

Several deposition products run as web services. Check each vendor's site for Mac support, pricing and data terms before you trial one. A long feature list does not prove the tool handles your transcript format.

AI can speed up a first draft. It cannot tell you what a witness meant. Accuracy is the risk that matters most. In a 2024 study, leading legal research tools hallucinated between 17 and 33% of the time. That study tested research tools, not deposition summarizers, so the rate for summary tools is unknown.

The ABA's 2024 survey points the same way. Of the attorneys surveyed, 75% named accuracy as their top AI concern. Plan for checking time. A fast draft that needs a full re-read saves very little.

Protect client data before you paste a transcript

A transcript is client data. Your firm or employer sets the rules on which tools may see it. Follow those rules before you paste, upload or dictate case facts into any app. No article can make that decision for you.

Data privacy is a common worry too. In the ABA survey, 47% named data privacy or security as an AI concern. Ask IT whether a tool is approved. Ask whether it stores audio, text or screenshots. Read the vendor's policy, not the homepage.

Lazur listens and looks at the screen only while you hold the shortcut. Audio and the screenshot go to AI providers so they can answer. They are not stored. Content is never used to train AI models. Those are Lazur's stated terms, and they do not replace your firm's rules.

Where Lazur fits in a deposition summary

Lazur is a voice assistant for the Mac that lives in the notch. Hold ⌥ ⌘ to ask about anything on screen, and it answers out loud. Ask where a button is, and Lazur draws a circle and a label around it. Ask how to do something, and Lazur guides you one click at a time.

That covers three jobs in a summary. It explains a Word or Pages screen when you forget where a setting lives. It drafts a template or a follow-up note and types it at your cursor. It answers questions about what is on screen. See the Word page for the details.

Lazur works from the screen you have open when you ask. It does not read a 200-page file in one pass. Treat any summary it gives you as a draft, and check it against the transcript before you rely on it.

Dictate your notes while you read

Reading and typing at once slows most people down. Dictate instead. Hold fn to dictate clean, formatted text at the cursor in any app. Say the page, the line and the note, in that order. Dictation is unlimited on both Lazur plans.

Pages has its own dictation. Go to Edit > Start Dictation, speak, and click Done below the microphone to finish. Apple's guide describes live dictation into a document. It does not say Pages transcribes an audio file, so do not count on that.

Voice Memos can transcribe recorded speech on a Mac where transcription is available. Apple notes that it is not available in all countries or regions. Use it for your own voice notes. Check the recording rules for depositions and client calls before you record anything.

Edge cases that add days

• Speakers who talk over each other. Mark those lines and check the audio before you cite them.
• Errata sheets. A correction can change an answer. Log it on the same row as the original line.
• Exhibits referenced but missing from the file. Log them as missing, so no one assumes they are attached.
• Multi-day depositions. Keep one template across all days, and label each day's pages clearly.
• Objections with instructions not to answer. Note who objected, what was said, and whether the witness answered.

Check the summary before it leaves your desk

Spot-check, do not skim. Pick a handful of entries at random and open the transcript to each page and line. If one cite is wrong, check the rest of that section. Wrong names, dates and exhibit numbers do the most damage.

Use the Find bar. In Word or Pages, press ⌘F, type a name, and step through each mention. This takes minutes. It catches the errors a quick read misses.

What the research says about time savings

Research on AI and lawyers is early. A randomized trial of law students found productivity gains of 50 to 130% in five of six legal tasks. The abstract gives no sample size. It does not show how much time a deposition summary would save. Read the study as a sign that tools can help, not as proof for your desk.

Begin with the template and the page count. Once you have a real reading speed, the math tells you how far ahead to start.
