A complete learning flow
Understanding is the start. Remembering is learning.
From opening a video to your next review, LogTuber connects every step in one continuous learning flow.
01 Read subtitles
Subtitles that follow the video without interrupting it.
Original and translated subtitles update with playback, and the current line is highlighted automatically. Use the panel to check context, or switch to floating subtitles for immersive viewing.
- Display multilingual subtitles in sync
- Highlight and follow the current line automatically
- Choose between panel and floating subtitle modes
02 Understand context
Not just a word. Understand the sentence.
Select a word, phrase, or full sentence. LogTuber uses the current subtitles to explain its meaning, tone, and usage—bringing the translation, breakdown, and examples together.
- Understand the current context, not just a dictionary definition
- See translations, usage, explanations, and examples together
- Understand expressions without leaving the video
03 Save automatically
Every lookup becomes a note you can return to.
Once an explanation is ready, LogTuber automatically turns the selection, full original sentence, video timestamp, translation, and breakdown into a note. When you review it later, the original reason you looked it up is still there.
- Keep the selection and full original sentence
- Record the source video and exact timestamp
- Skip copying, pasting, and manual organization
