Demo Maker

Auto-generate narrated product demos from your codebase — locally, privately, across 7 platforms.

The Problem

You ship features every week, but making a product demo takes longer than building the feature itself. Screen recordings are shaky and unscripted. Editing video is a separate skill. And every platform needs different dimensions, timing, and tone. Most developers just... don't make demos. Their work goes unseen.

The Solution

Demo Maker is a free IDE plugin (Cursor and Claude) that reads your codebase, generates a narration script, captures your UI with Playwright, narrates with a consistent AI voice via ElevenLabs, and renders platform-optimized MP4s with Remotion. One command produces 7 videos — Full, Twitter, Product Hunt, GitHub, Instagram, TikTok, and GIF. Everything runs locally on your machine. No uploads, no accounts, no SaaS dependencies.

Free and open source. Install in your IDE and ship your first demo in minutes.
