Product demo videos for SaaS teams

SaaS products change constantly, and the demos meant to sell them go stale the moment the UI moves. RunDemo fixes the economics of keeping demos current: you paste your product URL and describe the flow, an AI agent opens your app in a real browser and performs it, and a studio-quality voiceover is generated and synced to every click. No screen recording, no editing timeline.

The result is a shareable narrated MP4 of your actual product, the same one your customers use, that you can regenerate in seconds when the UI changes. That turns demo video from a one-off project into something your team maintains as easily as a doc.

Product tours that match the product

The homepage product tour is usually the first real look a prospect gets, and it is also the video most likely to lie about your app because it was recorded three redesigns ago. With RunDemo the tour is generated against your live product, so the buttons, copy, and screens are the ones a visitor will actually see when they sign up. When you ship a redesign, you re-run the demo and the new UI is captured automatically. No re-recording, no scheduling the one person who knows the golden path.

Because the narration is a transcript you edit rather than a take you perform, you can tune the story without touching footage. Tighten the hook, reorder the value points, or drop a step, and the browser re-performs and the voice re-renders around your edits in seconds.

A demo for every feature, not just the flagship

Most SaaS teams have one polished demo and a long tail of features no one ever filmed, because a recording session per feature is not worth it. RunDemo removes that ceiling. Each feature demo is a prompt: point it at the relevant screen, describe what to show, and generate. Ten feature demos is ten prompts, not ten recording sessions, so the pricing page, docs, in-app tooltips, and help center can all carry a short narrated clip of the exact thing they describe.

These clips also stay honest over time. When a feature gets an option or a redesign, you regenerate the one demo affected instead of re-filming a monolithic overview.

Changelog and release videos on the same day you ship

Release notes are read; release videos are watched. But most teams skip the video because the change ships faster than anyone can record it. RunDemo lets the person who wrote the release note also generate its demo: describe the new flow, point at the feature, and attach a narrated MP4 to the changelog, the in-app announcement, and the launch email, all on ship day. If your product is behind a login, RunDemo can drive it with test credentials that are used only for the render and deleted afterward, so gated features get demos too.

One workflow, many surfaces

The same generated demo can live in a dozen places: the homepage hero, a feature page, a sales follow-up, an onboarding email, a support macro, a social post. Because regenerating is cheap, you keep a single source of truth per flow and refresh them all when the product moves, instead of hunting down stale videos across your marketing site. Free to start, then Pro at $29/mo for 30 demos and Scale at $99/mo for 150, which is roughly the cadence of an active SaaS release calendar.
