Yes. The extension is free to install and use from the Chrome Web Store, and the source code is open on GitHub under the GPL-3.0 license. The only potential cost is if you choose to connect a large-language-model provider, which bills you directly for your own API key.

Do I need an API key to use it?

Only for LLM-powered translation. Dictionary lookups and classic engines work without one, but to translate through OpenAI, Gemini, Moonshot, or DeepSeek you must paste in your own provider API key.

Is lingo link an official product of Youdao, Google, or OpenAI?

No. It is an independent, third-party browser extension built by a single developer. The service names you see listed simply refer to the engines the extension can call; none of those companies publishes or endorses it.

Is the project still being updated?

According to the project's own GitHub README, development has stopped and the author recommends looking at a newer project instead. The published extension still installs and works, but it should be treated as unmaintained software.

What is lingo link's monthly traffic and growth trend?

lingo link currently receives 0 monthly visits, with a month-over-month traffic change of +0 (0.0% growth rate). Its primary source market is Global (— share), including 0 direct visits/mo and 0 organic search visits/mo.

Is lingo link free? What is its pricing model?

lingo link operates on a Freemium pricing model. Free to download from the Chrome Web Store and to use; the project is open source. Using large-language-model translation requires your own paid API key from a provider such as OpenAI, Gemini, Moonshot, or DeepSeek, billed directly by that provider. There is no paid tier sold by the extension itself. Supported billing and checkout platforms include: not listed.

About lingo link

Highlight-to-look-up dictionary

Select a word on any page and get concise and Collins-style dictionary entries without leaving the article you are reading.

Multi-engine translation

Translate selected text with classic engines (Youdao, Google) or route it through large language models like OpenAI, Gemini, Moonshot, and DeepSeek using your own API key.

Vocabulary bookmarking with notes

Collect unfamiliar words into a personal list and attach your own notes so you can review context and meaning later.

Re-highlighting of saved words

Words you have already saved reappear marked on pages you visit, so repeated exposure to the same vocabulary reinforces memory.

Flexible vocabulary sync and accounts

Keep word data locally, sync it to a Eudic dictionary account, or store it server-side via the built-in account system.

lingo link approaches language learning from the reading side: instead of pulling you into a separate study app, it lives in your browser and reacts to the text you are already reading. Selecting a word or phrase opens a compact panel with dictionary lookups and translation, so the flow of reading is interrupted as little as possible.

The extension supports several translation backends. Simpler lookups rely on dictionary-style and Google-style services, while advanced translation can be routed through large language models such as OpenAI, Gemini, Moonshot, and DeepSeek — these require you to supply your own API key, since the extension does not bundle model access. Saved words can be stored locally, synced to an Eudic (Oulu) dictionary account, or pushed to a server through the built-in account system.

One thing to know before installing: the developer has publicly stated on GitHub that lingo link is no longer maintained and has pointed interested users toward a newer project. The published extension still installs and runs, but you should not expect new features, updated integrations, or timely bug fixes. As with any extension that can read page contents, review the permissions before adding it.

High-Impact Use Cases for lingo link

Language learner

Read native-language articles without breaking flow

Work through news, blog posts, or social threads in a foreign language, looking up only the words you do not know instead of switching to a separate dictionary tab for every sentence.

Student

Build a vocabulary list from real reading

Collect words you meet in textbooks, papers, and online articles into one list, add short notes about how each word was used, and review them after the reading session.

Power user

Choose your own translation engine

Point the extension at a self-supplied LLM key when you want nuanced, context-aware translations, or fall back to classic engines when you only need a quick gloss.

Open-source enthusiast

Self-host or inspect the code

Because the extension is GPL-licensed and published on GitHub, you can read the source, build it yourself for Chrome, Edge, or Firefox, and verify how your reading data is handled.
