AI Subtitle Translator

Description

AI Subtitle Translator is an online tool that translates subtitle files into 50+ languages using AI for context-aware accuracy. Users upload a subtitle file, choose target languages, and download the translated result, with the source language detected automatically.

The tool supports multiple subtitle formats for input, including SRT, VTT, SBV, SUB, ASS, LRC, and SMI, and can process several files at once, with up to five files per batch sharing the same target language. Translated output is delivered in SRT format, so style information from formats such as ASS may not be preserved, and a bundled Subtitle Converter can convert results into other formats. Two model tiers are available: a Basic model with faster, lower-cost translation and a Plus model that uses more advanced AI for higher quality.

Alongside translation, the service includes free browser-based utilities. The Subtitle Converter batch-converts subtitle files between formats with a ZIP download, and the SRT Cleaner removes HTML tags, SDH elements, watermarks, speaker labels, and fixes uppercase text, all processed locally in the browser without uploading files.

New users receive free credits on registration, and a limited Basic free mode runs in a slow queue with daily limits. Paid options include a one-time 200-credit pack and auto-renewing Pro and Pro+ subscriptions, with subscription credits refreshing each cycle and not carrying over.
