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.
