About this extension

CapScript Web turns any YouTube video into something you can search and talk to. Find every mention of a keyword, phrase, or topic in a transcript and jump to the exact second with one click, using Smart, Exact Phrase, or Contains search and a timeline that marks every hit on the progress bar. New AI chat lets you ask a video for a summary, key points, or action items, with clickable timestamp citations on every answer, using Gemini, ChatGPT, Claude, or local models through Ollama or others with your own API key. Save transcripts to a local library, export results as CSV, JSON, or TXT, and work in any caption language YouTube offers, all without creating an account. Search and storage stay in your browser, and AI chat sends transcript text only to the provider you choose, or nowhere if you run Ollama locally.
