Kogvio

Kogvio is a Chrome extension that puts an intelligent overlay on your screen. Point it at a complex diagram, a page of advanced mathematics, or a block of technical documentation, and it explains what you're looking at without making you switch tabs. It's built for people who need to understand dense material quickly — students wrestling with textbooks, engineers reading architecture diagrams, or researchers scanning messy handwritten notes.

The extension works by analyzing whatever is on your screen using its own vision model. It can read bad handwriting, parse LaTeX equations, and even handle color-coded code blocks. If something isn't clear, you can ask follow-up questions through a contextual chat panel that appears right next to the scanned content. There's no need to set up API keys or juggle separate accounts — you just log into Kogvio and start scanning. The free plan gives you five scans per day, which is enough to test it out, while the Pro plan (₹199/month) removes limits and adds a more advanced reasoning engine.

Kogvio is most useful for students and professionals who regularly work with technical or visual material. If you've ever squinted at a whiteboard photo from a lecture, struggled to read a colleague's handwritten diagram, or needed to quickly understand a formula in a PDF, this tool saves you the hassle of manually transcribing or searching for explanations. It's a focused utility, not a general-purpose assistant — it does one thing (explain what's on your screen) and does it well.
