FSMB AI Script Tools

Automatically inject scripts into HeyGen AI avatar video projects with multi-tab workflow support.

HeyGen AI Avatar Video Automation Extension What does it do? This is a Chrome browser extension that works with HeyGen (an AI avatar video creation platform). Its main purpose is to automate the manual process of injecting scripts and rendering videos — saving time for creators who make videos at scale. How it works, step by step: 1. Script Injection When you open the HeyGen video editor in Chrome, the extension automatically injects your pre-written script directly into the editor — no manual copy-pasting needed. 2. Render Detection The extension silently monitors network requests in the background. The moment HeyGen finishes rendering your video, the extension detects it instantly — no need to keep refreshing the page. 3. Auto Download As soon as rendering is complete, the video is automatically downloaded to your computer without any extra clicks. 4. Side Panel A side panel opens alongside the HeyGen editor so you can control the extension while working — everything is visible in one place without switching tabs. 5. Access Verification The extension checks that only authorized users can access and use it, connecting to a verification endpoint for that purpose. Who is it built for?
