Product demos that make themselves
Describe what to show in plain English. An AI agent navigates your app, records pixel-perfect walkthroughs, and narrates every step — polished video documentation without a single screen recording or video edit.
Powered by the tools teams already trust
Three steps. Zero editing.
From a demo login to a published video in minutes — no screen recorder, no video editor, no voiceover artist.
Drop in a demo login
Paste your app URL and a demo account. LazyDemo signs in, crawls every page, and maps out your product — no extension, no install, no source code required.
Optional: connect a GitHub repo to deepen the AI’s understanding of your features. Most teams skip this and still get great results.
Direct in plain language
Tell the AI what to demonstrate — "show the onboarding flow" or "walk through invoice creation." It plans the recording, rehearses it live, and you approve before it rolls.
Everything a production team does,
without the production team
Script writing, screen recording, voiceover, video editing, cursor highlighting — handled.
AI voiceover narration
Natural-sounding narration generated from your product context — not generic scripts. Every word is timed to match on-screen actions.
Cloud browser recording
Pixel-perfect capture in a real browser environment. No extensions, no desktop recording software, no resolution issues.
Smart cursor & highlights
Custom cursor overlays and visual highlights draw attention exactly where users should look. Built into the rendering pipeline.
Say it. See it. Ship it.
You describe the walkthrough. The AI handles everything else.
Show how a new user creates their first invoice, adds line items, and sends it to a client. Keep the narration friendly and concise.
Planning 3 segments: Dashboard overview → Create invoice flow → Send & confirm. Estimated runtime: 2m 15s.
