Instant definitions, summaries, and maps in browser tooltips




ftak is a browser add-on designed to help readers understand text without breaking their reading flow. When reading articles, documents, or study materials online, encountering unfamiliar vocabulary or unfamiliar names often forces users to open new search tabs, copy terms, and jump between windows. This constant tab switching fragments focus and slows down comprehension.
The extension solves this problem by displaying dictionary definitions, Wikipedia-based factual summaries, and interactive location previews directly next to selected text inside a lightweight tooltip. Readers get immediate context on the active webpage without copying text or leaving their current task.
Unlike traditional dictionary extensions that only display single-word lexical definitions, ftak combines vocabulary lookups with broader topical summaries and map cards, functioning across both standard web pages and PDF files inside the browser.
ftak is built for anyone who spends significant time reading long-form text or technical material online, including:
A university student reading a research document in PDF format encounters technical terms and obscure references. Instead of toggling between search engines and the PDF viewer, the student highlights the terms to see instant definitions and contextual summaries directly on the document.
A news reader reviewing international reporting selects an unfamiliar city name. The tool provides a concise background summary and an interactive map showing the location without navigating away from the article.
A non-native English speaker reading long-form essays uses the tool to look up vocabulary definitions on the fly, keeping the reading pace uninterrupted.
ftak is completely free to install and use. It does not require a paid subscription, trial period, credit card, or user registration.
What platforms does ftak support?
ftak runs as an extension for Google Chrome and functions on standard web pages as well as PDF documents opened in the browser.
Does ftak require an account or sign-up?
No. The extension requires no registration, login, or personal profile to use.
Where does the summary and map data come from?
The extension retrieves factual overviews of people, places, and concepts using summaries from Wikipedia, alongside standard definitions and interactive map previews.
Can I use ftak on PDF files?
Yes, ftak includes built-in support for reading and highlighting text within PDFs directly inside your browser window.
