How I had my Claude agent record and narrate pre-call demovideos in my voice (and 3 steps for your next review call)

Yesterday and today, I stopped doing live screen-share demos on review calls. Instead, I had my Claude agent click through the app on test data, record the walkthrough, and narrate a 6-to-8-minute demo video in my own cloned voice before we met.

Why a pre-call video augments a live meeting instead of replacing it

It started yesterday before my call with a coaching founder building a daily habit app. Today I did the same for a founder building a family budgeting app.

We still met live on both days. Whether you are showing work to a client, your boss, or colleagues on your team, why make a video if you are already meeting live?

Because the video is not there to replace the meeting. It is there to augment it.

When you demo software live on a call, two things usually go wrong:

• You risk something breaking in front of the room. A test account expires, a screen hangs, or you click the wrong tab while everyone watches.
• The walkthrough eats up most of the clock. By the time you finish clicking through every screen and explaining how the pieces fit together, there is barely any time left for the features and decisions that matter most to the client, your boss, or your team.

Making a polished walkthrough video by hand would take hours of recording, re-recording when you stumble over a sentence, trimming pauses, and editing slides. Instead, my Claude agent clicked through every screen on its own, recorded its work, and stitched the whole story together in my voice.

I sent a 6-to-8-minute video before each call so they arrived already knowing how the app worked. That left the live meeting open for their questions.

What happened on both client review calls

Both times, the result was way better than I expected.

Yesterday, the coaching founder watched his 6-minute-40-second walkthrough before our 4:00 PM check-in. When he joined our call, he told me he walked over to his boss, showed the video to him, and said:

"This guy's crazy. Look at this."

His boss asked: "He already did that?"

Today, 90 minutes before our 4:30 PM review call, the founder building the family budgeting app watched his 8-minute-03-second walkthrough and emailed back:

"The video was extremely well done. I especially appreciated how you walked through the app from an actual user's perspective while also explaining the technical and security concerns behind the scenes. It made everything much easier to understand."

When we got on the call, his first comment was: "The unlisted YouTube video, I love that." Instead of spending 30 minutes explaining screens from scratch, we went straight into his priorities and decisions.

The 4 steps my Claude skill runs to build a demo video

After the first video landed well yesterday, I turned that workflow into a reusable Claude skill. Here are the basics of how my method works:

1. Run on safe fake data

Before recording a single frame, the agent spins up a local test copy of the app with live records and external services blocked. Every name, family, and number on screen is invented for the demo, so no real customer data is ever touched or shown.

2. Click through like a real user

Instead of clicking randomly through a menu bar, the agent rehearses and records one complete user journey from sign-in to finish. It holds each new screen for at least two seconds so a viewer can follow along, logs the exact timestamp when app sounds play, and runs a script that trims idle stretches longer than 2.6 seconds down to 2.2 seconds.

3. Narrate in my own voice over "Before" and "Now" cards

For each screen, the agent pairs the phone recording with clean "Before" and "Now" cards built from the project's actual bug list and pull requests. It explains what the user saw before and what happens now in plain English, sets an instrumental music track underneath that automatically ducks 13 to 24 dB whenever the voice speaks, and ends with a numbered card of questions that need a decision on the call.

Secret tip: ElevenLabs has an Instant Voice Clone feature. You only need to upload a minute of yourself talking and the resulting voice is surprisingly good. It adds a personal touch when the walkthrough speaks in your own voice instead of a stock announcer.

4. Check its own video before I watch it

Before handing the video to me for review, the agent runs an automated quality check on its own output:

• Audio transcription check: It transcribes the finished audio track and compares it word-for-word against the script to catch mispronounced words, initials, or product names.
• Dead-air and loudness check: It scans the voice track to make sure there is no unplanned silence longer than two seconds and normalizes loudness to -16 LUFS so the voice sits clearly above the music.
• Frame contact sheet: It grabs one frame from every scene into a contact sheet and scans for clipped text, system pop-ups, or any private data before I ever hit play.

3 steps to try before your next review call with a client, boss, or team

Even if you record a quick screen share yourself before automating it, you can use the same structure ahead of your next review meeting this week:

1. Send a 5-to-8-minute video two hours before the call. Give your client, boss, or colleagues a short unlisted link ahead of time so they can digest how the product works at their own pace before joining the room.
2. Follow one user journey from start to finish instead of clicking through a menu. Walk through a single person's day in the product, and pair each screen with one sentence on what was broken before and what works now.
3. End with the 2 or 3 decisions you need, so the call starts at the decision line. Put your numbered questions on the final screen and say what each decision unblocks. When the live call starts, you can skip the lecture and start right at question one.

Do you demo live or send a video first?
