The fastest way to summarize an article with AI is to not leave the page it is on. Lensia is an AI assistant that lives in Chrome, and its main surface is a sidebar chat that opens right next to whatever you are reading. Paste in a long article, or point it at the page, and ask for the key points. A few seconds later you have the gist, and because the chat stays open, you can ask "what did it say about pricing?" or "give me this in three bullets" without starting over. No copying into another tab, no losing your place. Install Lensia free and try it on the next wall of text you hit.
Read less, get more
Most things you read online are longer than they need to be. A report buries three useful numbers in ten paragraphs. A documentation page spends a screen explaining what you already know. Summarizing by hand means skimming, second-guessing whether you missed the important part, and scrolling back up twice.
Handing that job to an AI sitting beside the page changes the rhythm. You ask for a summary, read it, and decide in a few seconds whether the full thing is worth your time. Often it is not, and you have saved ten minutes. When it is, you already know what to look for.
The sidebar chat is where you summarize
Open the sidebar from the Lensia icon in your toolbar and a chat docks next to the page. Drop in the text you want condensed, or ask it to summarize what you are looking at, and it comes back with the main points.
What makes it more than a one-off is that the conversation stays open:
- Ask for a shorter version, or a longer one with the details you actually care about.
- Ask a follow-up without re-pasting anything: "what were the counterarguments?"
- Bookmark a summary you will want later, and scroll back to one from last week.
- Switch models mid-chat when a dense technical piece needs a sharper read.

Quick summaries with the floating panel
When you just want the gist of one section and do not need a back-and-forth, the floating panel is faster. Press Ctrl+Shift+X, drag a box around the paragraphs, and a summary appears on top of the page. Flip on Ask Mode to type your own instruction instead ("summarize this as a checklist") and attach an image or two if the page is part screenshot.
Pull in a page the AI cannot see
Some things you want summarized are behind a link you have not opened yet, or reference a source that is not on the page. On a paid tier, the sidebar can fetch a URL you give it and search the web, so you can say "summarize this article" with a link and let it do the reading. It is the difference between summarizing what is in front of you and summarizing something you have not opened.
What it is good at
- Long articles and blog posts — the three-sentence version before you commit to the full read.
- Reports and PDFs open in the browser — pull the findings out of the filler.
- Documentation — "just tell me how to do X" instead of reading the whole guide.
- Dense pages you half-understand — ask for a plain-language version, then ask why.
This is the same core habit that makes Lensia useful for research and for writing: read faster, ask better, stay on the page.
Plans
Sign in with Google to activate — that is the whole setup. Free covers the sidebar chat, the floating panel, Ask Mode, and the everyday models, which is plenty for summarizing on the fly. Stepping up adds fetch URL and web search so the AI can read pages you link, the stronger models for heavier documents, and more usage. If you want the AI to chain a few steps on its own, the top plan handles that too. For a broader look at where it fits, read the best AI tool for getting through your reading.
Start summarizing
Next time a page is longer than your patience, open the sidebar and ask for the short version. Install Lensia from the Chrome Web Store, sign in with Google, and get the point of anything you read in about the time it takes to scroll.
