Sublo — AI Subtitle Translator for Streaming

Sublo is a Chrome extension that translates subtitles in real time on Netflix, Disney+, HBO Max, Amazon Prime Video, Apple TV+, Crunchyroll, YouTube, and more. It displays dual subtitles — original and translated — powered by Gemini AI, so you can watch any show in any of 40+ supported languages without leaving the streaming service.

How it works
Install the extension, open your streaming platform, and hit play. Sublo automatically overlays a translated subtitle line beneath the original. There is no account to create, no configuration required, and no separate app to open. Pro users activate with a license key.

Key features

• Real-time AI translation via Gemini — noticeably better on natural dialogue, slang, and regional speech than machine-translation alternatives

• Dual subtitles on every major streaming service, including platforms competitors do not support (Apple TV+, Crunchyroll, HBO Max)

• 40+ target languages including Hindi, Bengali, Tamil, Vietnamese, Thai, Tagalog, Arabic, Hebrew, and all major European languages

• Free plan with 10 minutes per day, no sign-up required

• Pro plan at €2.89 / month (billed yearly) with unlimited subtitle minutes

Who it's for
Sublo is built for casual viewers who want to understand content in a foreign language, expats watching home-country programming, language learners who want immersion without complex tooling, and anyone who has ever watched a show with bad auto-generated subtitles and wished for something better.
