The Pain Points of Extracting Subtitles

As a real Japanese learner, I found it very inconvenient when using YouTube videos to learn Japanese.

The problem of inaccurate YouTube subtitle recognition

First, various bilingual plugins based on YouTube's built-in subtitle feature are actually very difficult to use, because YouTube's built-in subtitle feature recognizes completely inaccurately and can't break sentences properly.

Videos with built-in subtitles don't have the above problems, of course, but built-in subtitle plugins can't recognize them and require screenshots to be put into ChatGPT. But even taking screenshots is already troublesome, and then we have to ask AI specific questions. Moreover, this way the video and sentences can't be linked together, making it very inconvenient to review later.

Bunn's Solution

To solve the problems above, I created Bunn to optimize the entire workflow of YouTube Japanese learning.

Bunn turns any YouTube video into study material in 3 steps:

Step 1: Paste Your Video URL

Simply copy any YouTube video link and paste it into Bunn, and you can watch it in Bunn.

Step 2: Extract Subtitles with One Click

Bunn automatically detects Japanese subtitles from the currently watched video and generates memory cards with one click.

Step 3: Create Interactive Study Cards

Each subtitle becomes an interactive study card with:

• Japanese subtitle text with pronunciation standards
• Translation
• Dictation and shadowing

The Difference Between Bunn and Bilingual Subtitle Plugins

The difference between Bunn and bilingual subtitle plugins is very clear: Bunn is not a tool, but a solution.

Bunn is completely based on built-in subtitles, providing complete context recording and sentence collection functionality. Bunn fundamentally avoids the problems that bilingual subtitle plugins cannot avoid—inaccurate subtitle recognition and poor sentence segmentation—and focuses on linking videos with sentences and learning and reviewing at the sentence level.

This is a completely different learning experience from bilingual subtitle plugins. If you also find bilingual subtitle plugins difficult to use, come try Bunn. I believe you'll have a completely different and new experience.
