About CapScript Web
CapScript Web: Search and Chat With Any YouTube Video
YouTube has no search inside videos. CapScript fixes that. Find any word, phrase, or topic in a transcript and jump to the exact moment, or ask an AI to summarize the video for you.
NEW: AI Chat With Any Video
Chat with any video you've fetched. Ask for a summary, key points, or action items. Every answer cites exact timestamps, and one click takes you straight there.
Works with Gemini, ChatGPT, Claude, or local models via Ollama
