| Hi HN, I’m a founder/developer who spends way too much time on YouTube lectures, tutorials, and conference talks. Most of the time, I just need a few key insights — but I end up watching hours of video to get them. I built InfoCaptor AI
to scratch my own itch. It’s a free Chrome extension that: Transcribes(unlimited) and summarizes(limited) any YouTube video in seconds Extracts key entities, tags, and categories Builds word clouds and knowledge graphs so you can see connections between ideas Lets you save transcripts and summaries into a personal knowledge base The idea is to make YouTube as scannable and searchable as text — turning it from a time sink into a “second brain” for research. Why I built it:
As someone who dives into multiple subjects, I was frustrated that my notes from videos were scattered and inconsistent. I wanted a way to see the key concepts, link them across videos, and revisit them quickly. How it works: Install the Chrome extension → Open any YouTube video One click → Transcript + AI summary + entity extraction It automatically saves to local storage and into the cloud → Organize by channels, tags, or categories Visualize it → Dashboards, word clouds, and knowledge graphs Demo:

Thanks for checking it out — and if you try it, I’d be grateful for your honest thoughts and criticism. — Nilesh (creator of InfoCaptor AI) |
