5 Best Chrome Extensions for Research

Doing your research for seminar at uni, work presentation or just for personal learning? Sometimes it can take ages. Luckily not only we can skip going to the library these days but also there are tools to cut down on some manual and monotonous tasks. Today we're going to speak about Chrome Extensions that are best for research. Chrome add-ons have a very easy set-up and can do wonders for your work! They cut the slowest parts: watching long videos, retyping text from images, saving sources, and keeping highlights in one place. Our list covers five research tools that work right inside your browser, from AI YouTube summaries to a citation manager.
How we picked these extensions:
Saves real time on a common research task
Has a free version or a free plan to start
Fits a research workflow: find, understand, save, cite
Whether you are a student writing a thesis, a marketer doing competitor research, or a developer reading documentation, these productivity extensions will help you research faster.
1. Clarify AI: Screen Answers - screenshot AI and OCR extension
Clarify AI: Screen Answers lets you ask AI about anything you see in your browser: a chart, a paragraph, an error message or an image. Select an area of the screen, and the extension reads it, explains it and answers questions about it, without copying text into another app.
This matters for research because a lot of useful information is locked in images: charts in reports, tables in scanned PDFs, slides in webinars, screenshots in forums. Screen Answers uses OCR (text recognition) to unlock it.
Key features:
Extract text from images and screenshots (OCR)
Explain or answer what's on the screen in one click
Summarize and translate captured content
Follow-up chat about the same capture
Keyboard shortcuts that work on any website
Best for: reading charts and data in reports, understanding diagrams, translating foreign-language sources, and decoding error messages during technical research.
Price: free version with limits; subscription up to about $4 per month.
Why it stands out: most AI assistants only read text you paste. Screen Answers works with what you see, which makes it the missing piece for visual research. Also available on Opera, Mozilla, Edge and Brave.
2. Zotero Connector - free citation manager for Chrome
Zotero is a free, open-source tool for collecting, organizing, annotating, citing and sharing research. Its Chrome extension, the Zotero Connector, saves any article, paper, book or web page to your library in one click, with the author, title and date filled in automatically. It recognises sources on sites like JSTOR, arXiv, news outlets and library catalogues. Later, Zotero builds your bibliography for you.
Key features:
One-click saving of articles, PDFs and web pages with full metadata
Collections and tags to organize sources by project
Automatic citations and bibliographies in Word, LibreOffice and Google Docs
9,000+ citation styles, including APA, MLA and Chicago
Shared group libraries for team research, at no cost
Best for: academic research, theses, literature reviews, and anyone who needs to cite sources correctly.
Price: free; optional paid cloud storage for large file libraries.
Why it stands out: it is run by a non-profit and is open source, so your research data stays under your control.
3. Clarify AI: YouTube Summaries - YouTube Video Summarizer
Clarify AI: YouTube Summaries turns any YouTube video into a short, structured summary, so you can decide in a minute whether a one-hour lecture is worth watching. For video research, it is the fastest way to get the key points without scrubbing through the timeline. Clarify AI is a full YouTube AI assistant that helps you analyze content, not just a summarizer.
Key features:
Video Summary: the main ideas of a video in a few seconds
'Ask about the video': chat with the video and get answers based on its content
Timestamps: jump straight to the part you need
Bookmarks: save important moments for later
Comment summaries: see what viewers agree, disagree or ask about
Custom prompts: create your prompts to make the most of the summary
AI Models choice: choose the model that suits your needs best
Customise summary length, translate it and more.
Best for: students watching lectures, researchers reviewing conference talks, and anyone who learns from tutorials or podcasts.
Price: free version with daily limits; paid plans (from $2.99 to $4.99) unlock more summaries and features.
Why it stands out: most YouTube summary extensions stop at a summary. Clarify AI lets you ask follow-up questions and analyse the comments, which makes it a real research tool rather than a shortcut. Also available on Opera, Mozilla, Edge and Brave.
4. Google Scholar Button: tool for finding academic sources
Google Scholar Button is Google's official extension for looking up scholarly articles from any web page. Select a paper's title, click the button, and it finds the full text on the web or in your university library. The add-on turns any web page into a starting point for academic research, without opening a new tab.
Key features:
Find full text of a paper by selecting its title on any page
Search Google Scholar from your toolbar: see the top three results in a pop-up
Formatted citations in common styles, ready to copy into your paper
Save articles to your Scholar library to read or cite later
Library links to your university's subscriptions, including off-campus access
Best for: finding peer-reviewed sources, checking whether a claim is backed by research, and getting the full text of papers.
Price: free, published by Google.
Why it stands out: it connects everyday browsing with academic databases.
5. Readwise Highlighter - web highlighter and read-it-later tool
Readwise Highlighter is the official browser extension for Readwise Reader. It lets you save articles to read later and highlight or annotate any web page, so your best findings don't get lost in open tabs. Every highlight syncs to your Readwise account and, if you like, to note-taking apps such as Obsidian, Notion, Roam Research, Evernote and Logseq.
Key features:
Highlight and annotate any web page
Save for later: articles, newsletters, RSS, PDFs and EPUBs in one reading app
Sync highlights to Notion, Obsidian and other note apps
Daily Review that resurfaces old highlights so you remember them
Best for: literature reviews, long-term research projects, and building a personal knowledge base.
Price: paid subscription, with a free 30-day trial and no credit card required (Readwise). A Readwise account is needed to use the extension.
Why it stands out: it connects reading and note-taking. Highlights don't stay in the browser; they flow straight into the app where you write.
