Immersive Translate alternative: free and private bilingual translation

Twinread does one thing Immersive Translate does: it shows a web page in two languages, with the translation under each paragraph. The difference is where the translating happens. Twinread hands the text to the translator built into Chrome, so it runs on your computer, with no account. Immersive Translate does a lot more, and this guide says where.

Needs Google Chrome 138 or later on desktop. No account, no API key.

Which one to pick

Pick Twinread if you read web pages in Chrome on a desktop, want the text to stay on your computer, and want translation with no account and no limit on pages or length.

Pick Immersive Translate if you want to choose between AI models and translation services, translate PDFs or video subtitles, use Firefox, Safari or Edge, or read on a phone.

The two side by side

Immersive Translate details come from its home page (immersivetranslate.com/en/), pricing page (immersivetranslate.com/en/pricing/) and privacy policy (immersivetranslate.com/docs/PRIVACY/), read in September 2026. Its terms change, so check them before you decide.

Where the text goes

A translation extension has to read the text it translates, so the question is what happens next. In Twinread the text goes from the page to Chrome's translator, which runs on your computer, and the result comes back to the page. The only thing Twinread sends anywhere is your licence key, when a Pro pass is activated or checked.

Immersive Translate lets you pick an engine, and its privacy policy says: "When using webpage translation, your translation content will only be sent to the translation engine you select." So a translation service or an AI model receives the text you translate. That is how a multi-engine tool works, and the policy says it plainly. The safety guide goes through it line by line.

Limits, account and price

Twinread's free plan translates pages, selections and single paragraphs, in both display modes, with no limit on pages or length. Pro adds sites that translate as they load, translation of what you type, a glossary and custom styles. New installs get 7 days of Pro. After that Pro costs €12 for a month or €79 for a year, as a one-time pass. Nothing renews.

Immersive Translate can be used free. Its pricing FAQ says "daily translation requests are subject to a reasonable limit (higher quota after registration)".

Where Immersive Translate is better

• More engines. It lists over 20, including ChatGPT, DeepL, DeepSeek and Gemini. If you want an AI model's phrasing or a particular service, Twinread cannot do that. It has one engine.
• Documents and video. It handles PDF, ePub and subtitle files, and bilingual subtitles on video sites such as YouTube and Netflix. Twinread translates web pages only, and Chrome keeps its own PDF viewer off limits to extensions.
• Other browsers and phones. It runs in Firefox, Safari and Edge, and has apps for iOS and Android. Chrome's built-in translator does not work on mobile, so Twinread does not either.
• More language pairs. It lists more than 100.

What Twinread does on a page

Press Alt+A or the toolbar button. The translation appears under each paragraph and the original stays as it was. A small bar switches between Bilingual, Translation only and Show original without translating again. The side by side guide shows the steps.

Try it

Install Twinread, choose your two languages on the welcome page, and let Chrome download the language model once. After that translation works without a connection.
