InfoCaptor AI is a Chrome extension with a companion dashboard that turns YouTube videos into organized, searchable notes. For each video it creates a TL;DR summary, a full timestamped transcript, extracted entities, tags, categories and a word cloud.
What separates it from a basic summarizer, according to the vendor, is the visual layer. Summaries feed a force-directed knowledge graph that links videos, entities, tags and categories, so a library of watched content becomes something a user can explore rather than a list of text files.
The company describes the product as a second brain you can see. It is aimed at students, researchers, creators and professionals who spend time on long interviews, lectures and podcasts and want to retain and revisit what they learn.
The process starts when a user opens a YouTube video, clicks the InfoCaptor AI icon and selects Summarize. The extension detects the active video and retrieves the transcript from the platform's caption data, where captions are available. Both official and auto-generated captions are supported.
The transcript is saved in the browser's local storage immediately, so it can be viewed offline for previously processed videos. A language model then produces a summary formatted into sections, while the tool also identifies entities such as people, brands, locations and concepts, and assigns tags and categories.
Logging in is optional. An account syncs transcripts and summaries to a cloud dashboard, builds dashboards by channel, tag and entity automatically, and enables the knowledge graph and global search. The site states that data transfer is encrypted.
Each processed video gets its own page with the TL;DR, a timestamped transcript and the embedded video. Entities and tags become clickable filters, and dashboards can be grouped by channel, tag or entity for browsing a collection.
Analysis tools include keyword frequency and density, interactive word clouds where larger words indicate higher frequency, and a bubble pack view that shows how tags and keywords relate to each other.
The knowledge graph ties these outputs together. Users can filter it by summaries, entities, categories or tags and zoom into clusters to spot patterns. Local dashboards work without an account, while cloud dashboards add cross-device continuity and shareable links for tag and channel collections.
