Highlight the handwriting, diagram, or dense paragraph you're stuck on. Kogvio explains it right there on the page — no new tab, no copy-paste.
Two features do the heavy lifting. The rest quietly makes every scan faster.
Add several images to the tray at once — pages of handwritten notes, a diagram and its caption, three screenshots of the same error — and ask one question across all of them. Kogvio reads them together instead of one at a time.
Save the questions you ask over and over — "explain like I'm reviewing for finals," "convert to pseudocode," "summarize in three bullets" — and fire them off with one click instead of retyping them every time you highlight something new.
Board formulas, scrawled notes, and photos of physical pages come through cleanly.
Math and syntax-highlighted code appear formatted, right next to what you highlighted.
Flowcharts, pathways, and architecture diagrams get explained node by node.
Ask a follow-up in place — Kogvio remembers exactly what you were just looking at.
Kogvio runs on its own backend. Log in once and start scanning immediately.
Chrome, Brave, or Edge — on any webpage, PDF, or local file you open.
You settle yourself down to finally read that complex research paper and tell yourself that you will concentrate and stay focused. By the time you reach the third paragraph you come across a wall of dense and unfamiliar terminology.
What you do is highlight the text, open a new browser tab, go to ChatGPT, paste the paragraph, and then request a simple explanation. You read the summary, go back to the PDF and take ten seconds to look for the place where you had left off.
Once two minutes have passed, it occurs once more—another confusing concept, another new tab, and another instance of copy-and-paste.
By the time you realize it, forty-five minutes have gone by. You check your browser and see that six different AI chat windows are open, and you find out that you haven't even completed the first page of the paper. You never intended to spend all that time—you had only been trying to understand what you were reading.
The issue goes beyond the difficulty of research papers; the actual problem is that your reading workflow is flawed. Each time you leave the page to look for an explanation, you disrupt your context and lose the progress you've made. The mental energy you use from constantly managing multiple tabs is consumed more quickly than the energy used actually reading.
A better method of reading online material that is difficult to understand does not require having a dozen tabs open.
The style used in academic and technical writing is quite particular and is seldom tailored to the reader. Reading a paper is not simply about taking in words; it involves struggling with long and complicated sentences and coming across a great deal of technical jargon which the authors suppose that you already understand.
As for the visual elements, there are dense tables, complicated diagrams, and acronyms which were defined twenty pages earlier. The amount of information presented calls for your full attention. Whenever you come across a concept that you don't understand, your concentration is ruined. You can't simply move on by skimming it, since the rest of the document depends on you grasping that particular point.
In order to cope with dense writing, most people have resorted to the copy-and-paste method: they locate a difficult paragraph, copy it, and then paste it into a different AI tool in order to work out what it means.
But as soon as you stop using your source material, you lose a lot of focus. You cease to have a physical position on the page; when you read the explanation and then go back, you usually forget the original context of the paragraph and have to reread the section in order to get back to the point where you left off.
The issue is not simply understanding since you also have to break your concentration. You're making your brain continuously context-switch between reading the paper carefully and keeping an active control of your browser tabs.
We generally attempt a number of different workarounds in order to overcome this friction, but they usually don't work.
The lack of context is the missing element in the entire process. When you are reading a paper, the explanation should be included in the paper and placed right beside the text which you are having difficulty with.
That is precisely the reason why I developed Kogvio.
Rather than opening a new tab, you remain in your current location. As soon as you come across a section of dense text, you simply highlight it and press a keyboard shortcut. A neat and simple window then appears directly on top of your page.
You are free to ask a question, after which you will receive a straightforward explanation in plain English about the specific paragraph that you highlighted and then be able to read the answer. Once you have finished, just close the section and then read the following line in your PDF.
You never switched to another tab, you never lost your position on the page, and you maintained your state of flow entirely.
This on-screen workflow alters the way you interact with nearly any difficult content available online. Below is an example of how it appears in ordinary situations:
Reading becomes a lot faster if you cease to use your browser as if it were a copy-and-paste machine. You suffer from less mental disruption since you're not having to manage windows and as a result your brain can remain completely concentrated on the topic in question. This in turn causes you to understand the material more quickly and results in much better long-term memory. Rather than merely organising the content you actually spend your time learning it.
Kogvio is a Chrome extension that is native to the browser and is designed to explain complicated text and diagrams while keeping you in the same context. It functions as an intelligent on-screen overlay which works directly on webpages, online PDFs, and local files that are opened in your browser.
This workflow is designed for anyone who reads difficult content daily:
It is simple to switch to this workflow.
The internet provides us with unlimited access to information, but proper understanding shouldn't demand that you break your concentration. Learning is most effective when you remain in the state of flow. If your daily activity involves reading online material that is dense and difficult, then Kogvio is designed to fit your workflow.
Essential AI vision for individuals and quick daily tasks.
Unlimited scans, the Context Tray, and Custom Prompts for the heaviest reading days.
Yes. Kogvio is a Google Chrome extension. As long as you're using Chrome, Brave, or Edge on your computer, it works regardless of your operating system.
A single highlight only sees that one image. The Context Tray holds several images at once — multiple pages, diagrams, or screenshots — so you can ask a question that depends on all of them together, like whether two pages of notes agree with each other.
Yes. Our vision model is built to read bad handwriting, scanned photos of physical notes, and messy equations.
No API keys required. Kogvio runs entirely on our own dedicated backend servers. You just log in to Kogvio and start scanning immediately.
We support all major payment methods securely. You can upgrade using debit/credit cards, netbanking, or mobile payment apps.
