Screenova

Screenova is a browser add-on built around one simple loop: grab it, read it, understand it. You take a screenshot of any part of a web page, and the extension uses optical character recognition to lift the text out of the image, then hands that text to an AI model that can explain concepts, produce a summary, or turn a messy block of text into a short list of action items. It is the kind of tool that quietly removes friction from research, studying, and inbox triage.

Because the extension lives in the browser toolbar, it works across almost any site — documentation, lecture slides pasted into a chat, a scanned receipt, a thread you want condensed. The listing advertises model selection among well-known chat models (ChatGPT 3.5 and 4 are named), so you can pick the level of reasoning you need for a question versus a quick gist. Everything runs from a single capture flow rather than a dashboard, which keeps the learning curve near zero.

The project is small and independently maintained, offered by the Screenova.app team, with a stated policy of not selling user data and limiting collection to website content. It has a modest install base and no rating history yet, so it is best treated as a handy utility rather than a heavy-duty enterprise tool. Version history is short, but the listing remains published and installable in the Chrome Web Store.
