Can you add voice narration to an interactive demo?

Yes. Narration is recorded alongside the demo so each step plays its own portion of the audio, and microphone and webcam are independent — you can record a voice without appearing on camera. It is on Demorta's Growth plan at $39.99 a month.

Should every demo have narration?

No. Narration suits a flagship demo, where trust matters and the viewer is already engaged. Feature demos, help-centre demos and anything sent cold are better silent, because those viewers are scanning and often have sound off.

What is the downside of narrating a demo?

It removes skimmability and ages faster. A viewer wanting to check one screen now has audio playing at them, and re-recording a single screen means matching the voiceover around the edit rather than just swapping an image.

Interactive Demos With Voice Narration

August 20, 2026

Narration over a stepped demo is the hybrid between a video and a clickthrough: a person explaining each screen, while the viewer keeps control of the pace.

It is the strongest format available for a flagship demo, and the wrong choice for most of the others.

What a voice actually adds

Trust. A person talking reads as a company with people in it, which matters most in founder-led sales.
Emphasis. Tone carries which part of a screen matters in a way a caption cannot.
Context between steps. Explaining why you are about to click something is awkward in a tooltip and natural in speech.

What it costs you

Skimmability. A viewer who wanted to check one screen now has audio playing at them, and many people watch with sound off, in an office or on a train.

It also ages faster. Re-recording one screen in a silent demo is minutes; re-recording it in a narrated one means matching the voiceover around the edit.

Use it on one demo, not all of them

The homepage demo, the flagship walkthrough, the one you send to a prospect who has already had a call. Those earn a voice.

Feature demos, help-centre demos and anything sent cold are better silent — those viewers are scanning, and captions serve them better than audio they will not turn on.

How it works and what it costs

You record narration while recording the demo, so each step knows where it sits in the audio and plays the right portion. Webcam and microphone are separate — you can record a voice without appearing on camera.

Narration is on the Growth plan at $39.99 a month, alongside branching, quiz steps and drop-off analytics. Free and Starter do not include it, so if a voice is the reason you are here, Growth is the plan.
