YouTube Smart Video Search

Semantic search inside YouTube videos — jump to the exact moment.

YouTube Smart Video Search lets you search inside any YouTube video by meaning — not just keywords — and jump instantly to the exact moment you're looking for. How it works: Click the extension icon while watching a video, scan it once to index the transcript, then type anything in plain English. Instead of scrubbing through the timeline or skimming comments, the extension finds the relevant segment and takes you straight there. Why it's useful: Watching a long tutorial and need the part about a specific concept? Just ask. Reviewing a conference talk and want to find where a topic was mentioned? Type it. Rewatching a video and trying to locate that one moment? Done in seconds. Features: 🔍 Semantic search — understands the meaning of your query, not just exact word matches ⏱ Clickable timestamps — click a result to jump directly to that point in the video ⚡ Instant re-search — scan once per video, then search as many times as you want 🔒 Fully private — everything runs locally on your device, nothing is sent to any server
