Demosmith

Demosmith is a web-based AI demo generation tool. Using a browser agent, it automatically navigates your product UI to record, edit, add voiceovers, and insert subtitles—turning a single product URL into demo assets in multiple formats.

The Problem It Solves

Manually recording and editing demo videos is time-consuming, and frequent product updates quickly make existing demos obsolete. Demosmith eliminates manual recording and editing, producing multilingual, multi-format demo content in a single run.

Key Capabilities

• Autopilot Capture: A browser agent autonomously clicks, types, and scrolls, understanding context from the URL and prompts to operate the UI. It pauses to ask for user input when encountering steps that require intervention (such as two-factor authentication codes), then continues.
• Smart Editing: Automatically trims dead air and applies UI-aware zooms to key actions—no timeline or editing software required.
• AI Script & Voiceover: Generates narration scripts from prompts and provides voiceovers in 31 languages.
• AI Presenter: Adds an AI presenter video in the corner while keeping the product interface full screen.
• Dynamic Captions: Auto-generates captions synced with on-screen actions, supporting 31 languages and custom styles.
• Brand Kit: Apply your brand logo, colors, fonts, and custom intros/outros.
• Global Localization: Generate subtitles, on-screen text, and voiceovers in 31 languages in a single run.
• Fine-Tune Anything: Manually adjust details like narration, captions, zoom effects, blur effects, background images, and audio.
• Docusmith: Automatically generate help docs from your demos in Markdown, HTML, plain text, or PDF format.
• Interactive Demos: Turn recordings into clickable, interactive walkthroughs with embed and share link support, plus step-by-step funnel analytics.

Output Assets

Enter a URL and describe the workflow, and in about 10 minutes you get: MP4 demo videos (16:9), clickable interactive demos, Markdown/HTML/PDF help docs, blog posts, and upcoming 9:16 vertical videos.
