How to Run a Product Demo in Loom
The best product demo is one your stakeholders can watch on their own time, pause, rewatch, and share. Loom makes async demos possible — a PM can record a 5-minute walkthrough that replaces a 30-minute meeting with a 15-person calendar invite. Done well, a Loom demo is more persuasive than a live demo because you control the narrative and eliminate the "let me just find that screen" fumbles.
This guide covers setting up, recording, and sharing high-quality product demos in Loom — from a quick feature update to a full stakeholder presentation.
Step-by-step guide
Set up your Loom recording environment
Before recording, open Loom's desktop app and select "Screen + Cam" mode so stakeholders can see your face in the corner, which increases engagement by 30% compared to screen-only recordings. Set your screen resolution to 1920x1080 and close all non-essential apps to declutter your desktop. In Loom Settings > Video, select your best camera and confirm your microphone input. Use a dedicated USB mic or AirPods rather than a built-in laptop microphone.
Prepare your demo script and flow
Write a three-part structure: (1) Context — one sentence on the problem this feature solves. (2) Demo — walk through the feature in the order a user would encounter it, not in the order you built it. (3) So what — state the specific outcome for the viewer: "This means you can now onboard a new workspace without creating a support ticket." Keep the total runtime under 7 minutes. Attention drops sharply after that.
Start recording and nail the first 15 seconds
Click "Start Recording" in the Loom toolbar. Open with energy: state what you will show, why it matters, and who it is for. Example: "Hey team, I want to show you the new bulk import feature — this directly addresses the feedback from the Acme customer call last week." If you stumble in the first 15 seconds, stop and restart. Loom lets you trim the beginning and end without re-recording.
Use Loom's drawing tool during the demo
During recording, press D on your keyboard to activate the drawing tool. Circle or highlight the UI element you are talking about. This replaces "and if you look over here to the left" narration that leaves remote viewers lost. For important steps, use the Click to Highlight feature in Loom Settings which automatically adds a yellow highlight ring around every mouse click.
Trim and add chapters before sharing
After recording, click Edit in Loom's video editor. Use the Trim tool to cut any fumbles, long pauses, or accidentally visible Slack notifications. Then click Add Chapters to create timestamp markers: "0:00 — Context", "0:45 — Demo walkthrough", "4:30 — Q&A placeholder." Chapters allow viewers to skip to the part they care about and create a professional structure.
Add a CTA and share with the right audience
In the video settings, add a Call to Action button that appears at the end: label it "Give feedback" and link to a Notion page or Google Form. Copy the video link and paste it into Slack, email, or your Confluence page. In Loom Settings, require viewers to enter their email before watching — this tells you who actually watched vs. who just clicked through.
Common mistakes
Recording in a browser tab instead of the desktop app
The Loom browser extension records at lower quality and cannot capture other applications. Always use the Loom desktop app for product demos. It records at full resolution and allows switching between apps during the demo.
No editing after recording
Raw Loom recordings have long pauses, fumbles, and accidental screen clutter. Even 5 minutes of editing — trimming the start, cutting one stumble, adding chapters — makes the recording dramatically more professional. Loom's built-in editor requires no external software.
Demoing in production with real user data
Never record demos showing real customer data. Use a staging environment with synthetic seed data. Loom videos get forwarded and shared unexpectedly. A demo that accidentally shows a customer's email address or usage metrics creates a data breach.
Recording without a clear viewer
A demo "for the team" is for no one. Write the target viewer in your script notes: "This is for the AE team to understand the feature before the Acme call." Specificity changes your narration and makes the demo more useful.
Tips
Record at 2x the pace you think you need — you will speak slower when nervous and the final cut will feel natural
Use Loom's Background Blur feature if your home office is cluttered — it keeps focus on the screen content
Create a Loom workspace library organized by product area so demos are findable months later
Track Loom view analytics in the dashboard: if fewer than 40% of viewers finish the video, the demo is too long or poorly structured
How Vantage helps
Vantage generates user journey maps and prototype walkthroughs that you can use as a script for Loom demos. Rather than improvising a demo narrative, export your user journey from Vantage, use it to structure your Loom recording, and attach the Loom link back to the Vantage project as context for future team members.
