About DST
DST is a web tool for translating and editing subtitle files in SRT, VTT, ASS and SUB formats. It can translate files in bulk into any language using AI models such as GPT, Gemini, Claude, Grok and DeepL, or using Google Translate. The homepage states that timing and formatting stay intact after translation. A built-in editor lets users review and adjust translations before use.
Access is freemium. Google Translate is available at no cost, and most AI models can be tried through free demo trials. Premium AI translation is pay-as-you-go. Signing in is described as giving ad-free use, plan discounts and no payment fees. The number of files that can be translated at once depends on membership tier: 20 for Free, 50 for Basic and 100 for Pro, according to the September 24 update. For privacy, the site states that subtitle files are processed securely and are not used to train public AI models. Anonymous uploads are removed after the session ends, while files from signed-in users are stored for up to 30 days for re-downloading. These are the site's own stated policies, and the entry does not guarantee them.
