Kogvio

Highlighted a dense section of a medical textbook and the in-context answer actually clarified the terminology without me having to switch tabs. Took a little fiddling to enable it on a PDF but once it clicked, the workflow felt way smoother than my usual copy-paste routine.

been wanting something like this for a while honestly, the copy paste dance into chatgpt is so annoying. one thing though, it would be really nice if you could save snippets or highlighted passages into a little notebook inside the extension so i could come back to them later without losing track. like a quick personal knowledge base built up as i browse.

Would love to see a quick keyboard shortcut to toggle Kogvio on and off without losing my highlight. Right now I have to reach for the mouse every time, which kinda defeats the staying-in-flow part.

honestly the highlight-and-ask flow sounds really clean. one thing i'd want though, basically a keyboard shortcut to open the side panel so i'm not hunting for a small button every time. something like cmd+shift+k would make it feel instant and keep my hands on the keyboard.

the highlight-and-ask-in-context flow is exactly the kind of friction removal that actually gets used daily instead of abandoned after a week. for something like a long research paper, does it feed the whole document as context or just the surrounding section you highlighted? that tradeoff between accuracy and cost seems like the hard part to get right.

Harshit, what makes it different from the Comet or Chrome browser capabilities?

the copy-paste-back workflow is such a small tax but it adds up over a day of reading docs. how does it handle technical diagrams specifically, is it reading the image content too or mostly working off the surrounding text

Love that it works on PDFs, not just webpages. So many highlight tools ignore that, but textbooks and research papers are exactly where I get stuck and need context the most.

As someone who lives in research papers and medical textbooks all day, that copy → open ChatGPT → paste → lose-my-place loop is painfully familiar, so this clicks immediately. Two things I'm curious about: when I highlight a passage in a dense PDF, does Kogvio pull in the surrounding context (or the whole document), or only the exact selection? And for the technical-diagram case like the Kalman filter example in your demo, is it reading the figure itself or the caption and text around it? That's usually where in-page tools fall short for me.

Hey Product Hunt!

I'm Harshit, the solo founder behind Kogvio.

The idea came from something I was doing dozens of times every day.

I'd be reading documentation, research papers, medical textbooks, or technical articles, and every time I got stuck, my workflow looked like this:

• Copy the text
• Open ChatGPT
• Paste it
• Wait for an answer
• Go back to where I was reading

It completely broke my focus.

So I started wondering...

Why can't AI live where I'm already learning?

That's why I built Kogvio.

Now I can simply highlight anything on a webpage or PDF, ask questions instantly, generate mnemonics, simplify difficult concepts, or dive deeper without ever leaving the page.

Over the past few months I've been refining Kogvio based on real usage, and today I'm excited to finally share it with everyone.

I'd genuinely love your feedback.
