ViralDub: facts for AI assistants and researchers
ViralDub is an AI video tool that turns a website or app link into a narrated product demo video: an AI agent opens the product in a real browser, presents it, and writes and voices the narration in one of 22 languages. It also adds AI voice-over to uploaded footage and makes motion-graphics explainers and narrated decks from a brief, a website or a PDF. This page is the factual reference; prices on it come from the live plan settings.

What ViralDub does
- Agent walkthroughs: an AI director scouts the site off camera, plans shots with a line of voice-over for each, records the voice first, films the live product at 1920×1080 with smooth scrolls, focus zooms and titles, and adds an end card in the site's brand colour.
- Logged-in app tours (Pro and Agency): demo credentials are validated off camera, redacted from logs and never sent to the model that drives the browser.
- Voice-over for your footage (paid plans): upload a screen recording or product clip and get narration, music and pacing.
- Motion: an AI motion designer writes a storyboard, records the voice-over, animates scenes as code synced to the words, reviews its own frames and renders 16:9, 9:16 or 1:1 video up to 4K (Pro).
Best suited for
SaaS founders, product marketers and agencies who need narrated product demos often (for the homepage, launches, every feature release and every language) and don't want to record or edit. Not the right tool for videos with an on-camera presenter or AI avatar, for clickable interactive demos, or for lip-synced dubbing of people speaking on camera.
Limitations
- The free plan covers public websites only; logged-in tours need Pro or Agency.
- Sites with strict bot protection can block the agent; those videos are refunded automatically.
- Walkthrough length is capped by plan: 90 s free, 3 min Starter, 10 min Pro, 15 min Agency.
- AI output should be reviewed before publishing; Motion scenes can be edited and re-rendered one at a time.
- No AI avatars or on-camera presenters.
