Anyone who needs to localize video captions—whether for YouTube, TikTok, e‑learning platforms, or internal training—can benefit from its bulk translation and editing features.

How do I start a translation with AI Subtitle Translator?

First, drag and drop or upload a supported subtitle file (e.g., SRT, VTT, ASS). The system auto‑detects the source language, you then select one or more target languages, and click Translate. After processing, preview the result in the built‑in editor and download the translated file.

How fast does AI Subtitle Translator process files?

The platform is optimized for speed, typically completing a standard subtitle file within a few minutes. Processing time varies with file size and the number of target languages, but the cloud infrastructure ensures rapid turnaround even during peak usage.

What makes the translation quality reliable?

AI Subtitle Translator leverages advanced large‑language models that understand context, idioms, and domain‑specific terminology. Continuous model updates and language‑specific fine‑tuning help produce natural‑sounding translations that closely resemble native‑speaker output.

Can I edit subtitles after they are translated?

Yes. Every translated file opens in the integrated subtitle editor, where you can modify text, adjust timestamps, and customize styling before exporting. This hybrid AI‑human workflow ensures final captions meet precise brand or style guidelines.

Which subtitle file formats are supported for import and export?

The service accepts a wide range of formats, including .srt, .vtt, .sbv, .sub, .ass, .lrc, .smi, and plain .txt. Export options mirror the input formats, preserving compatibility with platforms like YouTube, Vimeo, and custom video players.

AI Subtitle Translator offers translation into more than 100 languages, with strong performance for widely spoken languages such as Spanish, Chinese, Japanese, French, and German. Each language model is regularly refined to capture regional nuances and idiomatic expressions.

Are there any limitations or usage caps on the free plan?

The free tier provides 10 free credits (≈1,000 characters per credit) and caps each file at 500 KB, with a 14‑day storage limit. Larger files, higher character counts, or multiple target languages require a paid subscription.

How does the pricing structure work and what credits represent?

Plans are subscription‑based (Free, Starter $9.90/mo, Pro $19.90/mo, Ultra $49.90/mo) and include a monthly credit allowance (e.g., 300 credits for Starter). One credit equals 1,000 characters of translated text; unused credits do not roll over, but higher‑tier plans reset credits each month.

What is the data privacy policy for uploaded files?

Uploaded subtitle files are encrypted in transit and stored temporarily only for processing and optional 14‑day access. Files are never used to train the AI models, and the platform complies with standard privacy regulations to protect intellectual property.
