Immersive Translate
Immersive Translate is a widely used bilingual web-translation browser extension. Backed by 爱玩Ai, it produces translations far beyond ordinary machine translation.
Step 1: Install the extension
Section titled “Step 1: Install the extension”Install from the official site: https://Immersive Translate.com
Step 2: Configure a custom API
Section titled “Step 2: Configure a custom API”Click the extension icon →Settings→Translation Services
Open OpenAI (or “Custom AI translation service”)
Fill in:
APIKEY: sk-your-api-key
Model: choose “Custom” and enter a model name (a light, fast model such as gpt-4o-miniis ideal)
Custom API endpoint: https://api.aiwanai.cc/v1/chat/completions
Step 3: Tune concurrency and cost
Section titled “Step 3: Tune concurrency and cost”Whole-page translation fires many small requests, so:
Max requests per second: lower it to 5–10 to avoid rate limits (429)
Max paragraphs per request: raising it reduces request count and cost
Pick a cheap model — translation doesn’t need a frontier model (prices on the Pricing page)
Step 4: Verify
Section titled “Step 4: Verify”Open any foreign-language page and enable translation from the extension icon. Translated text appearing means success; details are in Usage Logs.
Troubleshooting
Section titled “Troubleshooting”401: is the APIKEY complete (starts with sk-)?
Frequent 429: lower max requests per second, or see Error codes & troubleshooting.
Empty translations: try another model; a few models handle translation prompts poorly.
