SubAI for Stremio

Subtitles in your language on every Stremio device. When a title has no subtitles in your language, SubAI translates the best available track with an LLM the first time you select it. Later viewings are instant.

Stored only inside your personal addon URL. Never shared with other users.

Second line (dual subtitles)

Both lines always show. If the first language already exists for the title, that track is line 1 and line 2 is translated from it (one translation). Otherwise both are translated from the source (two translations). "Original" shows the untranslated source as line 2 at no extra cost.

Preferred source language

Which subtitle SubAI translates from. English has the best coverage on OpenSubtitles.
