Our billing standard is very clear and is mainly divided into two types based on the service:
Before you submit any task, the system will clearly estimate and display the credits this operation will consume. You can also check your detailed consumption history in the 'Personal Center' at any time.
We use OpenAI's latest GPT-4 model, the most powerful AI translation engine in the industry. Unlike traditional 'word-for-word' machine translation, GPT-4 understands context, cultural differences, and linguistic habits. We also offer an 'Expert Mode,' deeply optimized for professional fields like medicine, law, and technology. In tests, user satisfaction with translation quality reached 98%+, and many couldn't even distinguish it from human translation.
We support translation between 100+ languages, including all major languages (Chinese, English, Japanese, Korean, Spanish, French, German, etc.) and most minor languages (like Thai, Vietnamese, Indonesian, Turkish, etc.). Whatever language you want to translate into, we can handle it.
We charge by character count, with 1 credit being approximately 2 characters. For example: a 10-minute video has about 3,000-5,000 characters, consuming 1,500-2,500 credits, which costs $0.12-$0.20. The Starter Plan's 100,000 credits can translate about 40-60 ten-minute videos, which is very cost-effective. Plus, the credits never expire.
Our cloud GPU cluster is very powerful. Generally, a 10-minute video subtitle translation takes only 1-2 minutes, and a 1-hour video takes about 3-5 minutes. If you purchase a Professional or Enterprise plan, you'll receive priority processing for even faster speeds. If it's truly urgent, you can contact our technical support for special handling.
This is our top priority! We use bank-level AES-256 encryption for storage and are ISO 27001 certified for information security. Your uploaded files are only temporarily stored during the translation process and are automatically destroyed immediately after completion. Our engineers cannot view your content, and the AI model will not use your data for training. We protect your trade secrets and personal privacy as if our lives depend on it.
Of course! You can process up to 10 files at once. Select the same translation settings, and the system will automatically queue them for processing. When finished, you can download them all with a single click, saving you a great deal of time.
Absolutely! The downloaded files are in standard SRT or VTT format, which you can open and modify with any subtitle editor (like Aegisub or Subtitle Edit). If you're not satisfied with a particular term or want to adjust the timeline, you are free to edit it. We are also developing an online editor that will soon allow you to make changes directly in your browser.
We offer a 7-day no-questions-asked money-back guarantee. If you are not satisfied with the service within 7 days of purchase and have used less than 10% of your credits, you can apply for a full refund. We are very confident in our product, but we also respect your choice. The refund process is simple and fast, with the funds returned within 3 business days.
