TubeLens — AI layer for YouTube: summaries, mind maps, transcript & comment insights

Hey PH 👋

Honest origin story: we were doing a lot of research through YouTube — online courses, industry talks, foreign language content — and kept running into the same frustration.

The information is there. It's just locked inside a 40-minute video with no way to extract it without actually watching the whole thing.

So we built TubeLens. It's a Chrome extension that sits inside YouTube and gives you a full toolkit for actually processing what you watch — not just playing it.

What's inside:

⏱️ AI Summaries — Timestamped key points so you can decide what's worth watching before you commit. Also handy for revisiting content you've already seen.

🧠 Mind Maps — Converts the video structure into a visual map. Weirdly useful for lectures and long-form explainers where ideas build on each other.

💬 Chat with video — Ask specific questions, pull out exact answers, or compare two videos side by side. Saves a lot of re-watching.

🌍 Bilingual Transcripts — Side-by-side translations with search and loop features. We built this one specifically for language learners but it gets used for a lot more.

💡 Comment Analysis — Surfaces sentiment trends, common questions, and audience signals from thousands of comments. Useful if you're a creator or doing any kind of research.

🔍 Smart Search — Find the right video across a topic without watching ten of them to figure out which one's actually good.

Everything lives inside YouTube. Nothing to configure. Took us a while to get the UX right on that part.

We launched today and we're genuinely trying to figure out which parts people find useful versus which parts are just "nice to have."

If you've ever felt like YouTube has way more useful information than you can realistically consume — we'd love to know what you think.

→ Which feature would actually change how you use YouTube?

→ What's the one thing that would make this a permanent part of your setup?

Appreciate any feedback — good or rough. 🙏
