🚀 Add to Chrome – It’s FreeInfoCaptor AI isn’t just a simple transcript grabber — it’s a complete end-to-end intelligence engine that transforms raw YouTube content into a connected, visual knowledge system. Here’s exactly what happens, step by step:
As soon as you launch the Chrome Extension while watching a YouTube video, InfoCaptor AI detects the active video and accesses the platform’s caption data (where available). Using a secure, non-invasive method, the transcript is extracted in full — no matter if it’s a short 5-minute clip or a 3-hour podcast.
Once retrieved, the transcript is stored instantly in your browser’s local storage — meaning it’s available even offline. If you’re logged in, it’s also synced securely to your InfoCaptor Cloud Dashboard, where it becomes part of your searchable personal archive.
With a single click on the “Summarize” button, InfoCaptor AI’s language model processes the transcript to produce a structured, human-readable summary. This isn’t a generic one-paragraph summary — it’s intelligently formatted into sections with clear, concise points.
Alongside the summary, InfoCaptor AI identifies all notable entities mentioned in the video — people, brands, locations, events, and key concepts. Each entity becomes clickable and filterable within your dashboard.
Based on the video’s content, InfoCaptor AI assigns relevant tags and places it into pre-defined or auto-created categories. This creates an organized taxonomy for your knowledge base without manual input.
To give you a quick visual snapshot of the video’s focus, InfoCaptor AI builds a word cloud showing the most frequently used terms. Larger words represent higher frequency, allowing instant recognition of core topics.
Every new summary, entity, and tag updates your personal Knowledge Graph — a living network that maps how your videos, topics, and ideas are interconnected. This makes your learning visible and navigable.
With all data stored in structured form, you can search your entire library — by keyword, entity, tag, category, or even exact phrases. This turns passive watching into an active, reference-ready knowledge system.
