1、The world is so big, I'll check it out first
But, but, unfortunately, my English reading level has regressed to around the sophomore year level, and it was probably at its peak in the senior year. As for other languages like French, Japanese, German, ..., I can't even read a single word. In the era of the Internet as a global village, language barriers still exist strongly, and have you ever encountered the following situations that I often struggle with:
- Seeing a well-filled foreign language webpage, technical blog, or document, but being discouraged by long segments of English?
- Writing papers or reports and downloading some foreign language PDF documents or reports, using some translation software results in a complete mess in terms of formatting, making it uninteresting and causing a headache?
- Wanting to follow updates from YouTube gurus, but finding it too difficult to digest the raw content, and machine-translated subtitles are awkward and wrong?
- Anyway, when we encounter non-Chinese scenarios, we feel lost and regret not having studied foreign languages more seriously?
After trying over 15 translation apps, I finally found this one that's getting rave reviews all over the internet! Bilingual comparison! Bilingual comparison! Bilingual comparison! The strongest free translation tool 【Immersive Translate】. Trust me, uninstall other translation apps, you won't be disappointed!

3、Free software
Nothing to say. I am a poor person from Hunan, only can afford free software. Of course, 【Immersive Translate】has paid features, but I haven't used it, so I won't comment.
4、Bilingual comparison, immersive web translation
I'm a half-baked programmer, occasionally going to foreign websites to learn excellent projects and gnaw on English documentation. My previous approach was to use the full-page translation feature in Chrome, Quark or Edge browsers. But I found that the translations often didn't convey the meaning well.
For example, the function Function was often translated as "feature".Library code library was frequently translated to "book library". The translation quality was quite poor, sometimes it was even worse than switching back to the original text, which was very inefficient to switch pages back and forth.
But the Bilingual comparison ability of 【Immersive Translate】displays the translation directly under the original text without popping up a window, not interrupting the flow of thought. Reading the original and translated texts side by side is very friendly, and reading is basically unobstructed.

4.1 Translation Style Settings
By default, the translation text by【Immersive Translate】are displayed in the same style as the original text, making it seem completely natural so much that I sometimes can't tell which is the translation and which is the original text.
So I usually suggest setting the display effect of the translation. After clicking the "Settings" button of the plugin, find "Translation Display Style", set the translation color to a prominent red, or choose effects like highlighter, dotted underline, etc., so the difference between the translation and the original text is very obvious.

4.2 Advanced English Learning Tool - Study Mode
My general steps for browsing foreign language content are:
- First, skim the summary, translate the entire article or page at once, which can quickly get the main idea of the content.
- Second step is progressive intensive reading paragraph by paragraph. Tackle the original text on your own, understanding as much as you can, and then refer to the translation for parts you don't understand.
The "fuzzy effect (learning mode)" in "Immersive Translate" is truly an advanced English Learning tool. After setting "learning mode," the translation does not immediately appear but is instead blurred.
With this feature, you can force yourself to read English content first, and only refer to the Chinese translation when you indeed can't understand it, make it very suitable for training reading skills.
As shown in the figure below, first translate the entire text and then blur it:

Directly read the original text....Emm, can't understand? Then hover your mouse over the blurred translation below the original text and read the translation:

Wow, after training in this reading mode, I can now usually understand the original text directly most of the time.
I strongly recommend you don't read the bilingual comparison translation fistly, your English won't improve much and you might become a bit lazy and dependent. Let's start learning mode, only translate the parts you indeed can't understand, and your English reading skills will improve dramatically!
4.3 Translate the part you don't understand
After training like this for some period, you will truely be an English reading expert, a full text in English is no problem for you, there might be a few obscure parts. At this point, you can set it so you don't have to translate the entire text every time, just translate the parts you don't understand. After enabling the "Mouse hover + Translate this paragraph directly" in the settings, hover your mouse over the text, and you can translate a specific paragraph individually, point and click, it's really convenient.
4.4 Press space three times to translate immediately
Sometimes we want to search for high-quality English materials, in any search engine's search box, input Chinese content, then press three consecutive spaces, it will trigger the input box translation ability of immersive translation, and it will translate the Chinese we input into English, helping us to search more richer, propriet content.

6、Video subtitle translation
Webpage, PDF, EPUB translation is just three of the main useful features of this plugin. The most explosive feature is Immersive Translate supports translating subtitles on videos.

7、Freely Switch AI model
【Immersive Translate】supports switching between various translation engines. For example, if you are in a domestic environment and cannot use Google Translate, you can switch to free Microsoft Translate and Tencent Translate. If you want more accurate translation results, you can use the recently added free translation model: chatglm and siliconflow.
Each AI provide a certain amount of free translation quota in characters. It is recommended to set up "enable mouse hover + Ctrl translation for this paragraph" for single segment translation to save tokens and prevent over-quota which could result in charges!!!

8、Multi Client

For example, you can download the 'Immersive Translate Browser' from the app store, which comes with an immersive translation plugin. I often use it to read Hacker News and watch videos on Douyin during my commute, making the most of my fragmented time. Also, recently, isn't there a surge of foreigners on RedBook? There are a lot of English contents. By opening RedBook in the 'Immersive Translate Browser', you can read RedBook and comments in both languages!
