Why Use AI for Translation
Traditional translation software has two old problems: either the whole-page machine translation reads like "alien language", or it can only translate single sentences and chokes on long PDFs. The difference with AI translation is—it understands context, preserves tone, and can conveniently polish, summarize, and cross-reference the original for you.
- Bilingual comparison: original + translation side by side, so reading foreign text no longer "loses the context after translating";
- Handles long documents too: feed in a whole paper, contract, or e-book and get key points and extracted tables;
- More than just translation: also polishes your English emails, explains long difficult sentences, and rewrites the tone.
Two Types of Scenarios, Two Ways to Use
Method A: Immersive Translate, Bilingual Webpages / PDFs
Install the extension (5 min)
Install the browser extension in Chrome / Edge / Firefox / Safari; mobile app and desktop versions are also available. On first launch it guides you to pick a translation engine (the built-in free Chinese translation is enough to start, or you can connect DeepL / your own API key).
Open a foreign webpage, automatic bilingual comparison
Open any English site and it shows "original + translation" by default. If it's cluttered, switch to modes like "translation only / bilingual / show original on hover"; select text to translate instantly.
Translate PDFs / e-books / subtitles too
Upload a PDF to generate and download a bilingual version; convert EPUB e-books into bilingual paragraph-by-paragraph reading; show real-time bilingual subtitles on YouTube, Netflix, TED, etc., so you don't wait for subtitle groups.
Method B: Chatbot for Precise Translation and Polishing
When what you need isn't "reading" but "writing a passage of Chinese into natural English" or "explaining a difficult English sentence in plain words", this is the most stable approach: you give the original + requirements, and it returns a translation and explanation.
Paste the original, state the purpose and tone (1 min)
Say whether this is an email / paper abstract / product copy, formal or casual, and whether to keep technical terms (like product names, person names).
Apply the prompt for the translation (10 sec)
Send the whole block below, replacing the bracketed content.
Follow up on difficult sentences, finalize (2 min)
Ask directly "what does this sentence actually mean" for anything unclear; copy and use once confirmed. Don't upload the original for confidential content.
Prompt You Can Copy Directly
A Real Example
The original you provided (product copy tone, English to Chinese):
AI's two versions (excerpt):
- Literal: Our free plan lets you generate up to 50 images a month, with watermarked exports. You can upgrade any time to unlock HD and a commercial license.
- Polished (social-media tone): The free plan gives you 50 images a month, downloads come with a small watermark; want HD or commercial use—just upgrade anytime.
- Difficulty note: "commercial license" means "commercial-use authorization", not "business license"—don't write the latter in your copy.
Three Pitfalls to Avoid
- Verify critical content yourself: translation quality depends on the engine and source difficulty; for contracts, papers, medical, and other serious texts, review sentence by sentence—don't copy directly.
- Don't let it "translate" facts: AI sometimes conveniently fills in or rewrites the original meaning. For translation tasks, just have it translate—don't let it "summarize on the side" and distort the information; ask for a summary separately.
- Redact privacy first: for originals with personal info, trade secrets, or unpublished data, redact before translating; for sensitive content, prefer local / self-hostable solutions—don't upload to the cloud bare.
