What is AI Subtitle Translator?

AI Subtitle Translator is a translator tool that translates subtitle files into 50+ languages with AI. A focused web tool that translates SRT, VTT, ASS and other subtitle files into more than 50 languages, with automatic source detection, batch uploads and a free queue for light use.

AI Subtitle Translator is a browser based service for converting subtitle files from one language into another. It accepts the common formats used in video workflows, including SRT, VTT, SBV, SUB, ASS, LRC and SMI, so editors do not have to convert files by hand before starting. Source language detection is automatic: the user uploads a file, picks one or more target languages and runs the translation. The tool is aimed at video editors, localization freelancers, course creators and small media teams that need subtitles in several languages without hiring a translator for every version. A single file can be rendered into up to 10 languages in one pass, while multiple files can be batched toward one shared target language, with a limit of five files per submission. Two model tiers are offered: Basic, which is free and runs in a slower shared queue, and Plus, which costs more credits and is positioned as producing higher quality output. An optional translation configuration panel is available for users who want more control over the request. The main constraint to understand before paying is the output format. Whatever goes in, translated files come back as SRT, so styling held inside ASS or similar rich formats is not carried over. The site points users to a separate Subtitle Converter page to turn the SRT result into VTT, ASS or another format afterward. Uploaded and translated files are stored for seven days, which is enough for most jobs but means the download step should not be postponed. Very long subtitle files can fail because of model processing time limits, even though no strict word limit is advertised. Against alternatives, this is a narrow, single purpose tool rather than a full localization suite. It does not claim review workflows, terminology management or human post editing. What it does offer is broad language and format coverage at a low entry price, with a credit system that scales from occasional one off jobs to regular monthly use.

How do you use AI Subtitle Translator?

  1. 1Open the translator and upload your subtitle file
    Go to the homepage and drag your file into the upload area or click to browse. SRT, VTT, SBV, SUB, ASS, LRC and SMI files are all accepted, and you can add up to five at once if they share a target language.
  2. 2Choose the target languages
    Pick from the language presets or add a specific language. The source language is detected automatically. A single file can be sent to as many as 10 languages in one run, which covers most multi-market releases.
  3. 3Select a translation model
    Basic is free, runs in a separate slow queue and processes one task at a time with a daily limit. Plus costs credits but is described as higher quality. Choose according to how much the job matters versus how fast you need it.
  4. 4Run the translation and download the SRT
    Start the job and wait for the queue to clear, then download the translated files from the results or the My Subtitles page. Download promptly, because stored files are removed after seven days.
  5. 5Convert the SRT if you need another format
    Because output is always SRT, use the companion Subtitle Converter to turn the translated file into VTT, ASS or another format before importing it into your video editor.
  6. 6Check plans before scaling up
    Compare the credit pack, Pro and Pro Plus options on the pricing page if the free queue is too slow or you need more monthly credits. Credit multipliers for the paid models can change over time.
