Get started

Get started

Install FluentAI and pin the extension

Install FluentAI from the Chrome Web Store or Firefox Add-ons, then pin it in your browser toolbar. Pinning makes it easier to confirm the extension is active before you open Netflix, YouTube, Prime Video, Disney+, or HBO Max.

Open a supported video with subtitles

Choose a video that has subtitles or captions available. FluentAI works best when the streaming page exposes subtitle text clearly, because that gives you useful dual subtitles, word lookup, and saved vocabulary from the scene you are watching.

While watching

While watching

Turn on dual subtitles

Use dual subtitles when you need meaning and target-language text at the same time. Beginners can keep native-language support visible, while intermediate learners can replay the same scene with only target-language subtitles after they understand the context.

Click a word for context-aware help

Click an unfamiliar word or phrase in the subtitle overlay to see a translation and explanation in context. The goal is not to save every unknown word; pick words that affect the scene meaning or that you expect to hear again.

Playback modes

Replay short scenes instead of full episodes

A strong FluentAI session is usually one short scene repeated several times. First watch with dual subtitles, then target-language subtitles, then audio focus. This turns passive watching into listening practice.

Notebook & lists

Notebook & lists

Save useful vocabulary for review

Save 5 to 10 useful words or short phrases from each session. Keeping the source scene attached makes review feel like remembering a moment from the show instead of memorizing an isolated list.

Review after the episode

After watching, open your saved vocabulary and review the words that came from the scene. Short review sessions after real video keep the learning loop tight: watch, understand, save, review, then return to another scene.

Troubleshooting

Troubleshooting

If subtitles are missing, check the track first

If FluentAI does not show the subtitles you expect, check whether the streaming service has a matching subtitle or caption track enabled. Some titles have translated subtitles, some have captions, and some require a different title or fallback workflow.
