Demosmith

Demosmith is an AI agent for creating product demos: you give it your web app's URL and a prompt, and a browser agent walks through it like a real user to produce an edited demo video, an interactive demo, matching documentation, a product film and social clips. The company says more than 3,000 founders and product teams use it.

What is Demosmith used for?

It means no more recording and editing demos by hand. The agent clicks, types and scrolls on its own, understands your product's context and, if it needs something only you can provide, such as a login, it asks. It then applies smart editing: cutting dead time, zooming into key actions and polishing the pacing. A walkthrough of about ten minutes becomes six reusable assets for sales, onboarding and launches.

What does each Demosmith demo include?

Demosmith writes the script, adds natural-sounding voiceover and synced captions, and can include an AI presenter in a corner of the video. Everything is generated in 31 languages, including Spanish, applying your brand kit with logo, colors, fonts and intro. Docusmith turns the demo into a guide in Markdown, HTML, plain text or PDF ready for your help center, and the editor lets you tweak narration, captions, zooms or blurs.

Who is Demosmith for?

• SaaS startups shipping product updates weekly.
• Sales teams needing demos for each use case.
• Support teams maintaining guides with screenshots.
• Marketing teams publishing launch videos in several languages.

Demosmith pros and cons

Pros: several assets from one walkthrough, localization into 31 languages and unlimited seats. Cons: it works with web products reachable in a browser and, by the company's own account, about 5% of outputs need manual touch-ups.
