Frequently Asked Questions#

General troubleshooting: Press F12 to open DevTools, check the Network tab and inspect the Response. Most errors can be located there.

Why is the translation result empty, showing only the original text, or displaying as null?#

This can happen for several reasons:

• The API Key or related settings are incorrect.
• The available credits/tokens for your account have been used up.
• The translation rate is set too high, or the API itself is temporarily unstable.
• The selected AI provider (e.g., OpenAI, Gemini, Claude) may not support access from mainland China IPs. Please verify your network environment or use an access method allowed by the provider.

If only some content failed to translate, simply try clicking the "Translate" button again. When the translation cache is enabled, the system will skip already translated content, avoiding duplicate charges or requests.

What if AI translation quality isn’t ideal?#

Troubleshoot in this order:

• Reset to defaults: In “Translation Settings”, reset and retest with a short sample.
• Tune temperature (default 0.7):
  • 0–0.3: technical/strict terminology (stable/consistent)
  • 0.4–0.7: general content (balanced)
  • 0.8–1.0: more creative (marketing/paraphrasing)

Note: Most mainstream online 70B+ models are fine; issues are commonly due to inappropriate temperature.

Why is translation slower? Why does free GTX feel faster?#

The key is the “translation rate,” which is essentially the concurrency (how many requests are sent at once).

• GTX feels faster: Higher default concurrency and shorter responses, so it runs faster overall. But it’s more strictly rate‑limited, so large/long runs may get throttled.
• AI interfaces are safer by default: Lower default concurrency to reduce 429 (rate limit) and “context/token limit” errors, so beginners are less likely to hit failures.

Want it faster? Increase the “translation rate” from 20 to 30/50 gradually; if you see 429 or empty results, step back a bit.

Tips:

• With translation cache enabled, repeated content is skipped; subsequent runs are faster.
• Network conditions and the chosen model also affect speed; try a different model or time window if needed.

Why does this use a third-party interface to access DeepL?#

Because DeepL's official service does not allow direct calls from a webpage, we use a "proxy channel" to send the requests for you.

This proxy interface is only used to transmit data and will not collect any of your information, so you can use it with confidence. If you have higher stability requirements, you can also set up this channel yourself.

Will my API Key be saved?#

No! Your API Key and other settings are only saved in your own browser. We do not upload or record any of your information.

Why isn't the GTX Web interface enabled?#

The GTX Web interface puts significant pressure on the server, so it is not enabled by default.

If you are using this tool on your own computer, you can enable it manually. Please avoid using this interface in a network environment with a global proxy enabled, as it may cause translation anomalies.
