针对外语的转写能力还是不行，能添加日语转写的功能吗？

Yukidoh Satoru2026年3月1日

有些视频本来就带字幕，这里能否搞个区分，就不用转录了，直接用自带的字幕识别率还是差点意思，而且断句不行，既然支持Bilibili，就需要一个中文支持好的model

AI product read

Video-to-text transcription using local AI model

Extracts subtitles or transcribes audio from YouTube and Bilibili videos into text without uploading data to external servers

1. Install extension and Native Host. 2. Open YouTube/Bilibili video page. 3. Click extension icon to open sidebar. 4. Click 'Create Task' to start transcription. 5. Extension downloads audio via yt-dlp, sends to local Native Host for Whisper AI transcription. 6. Download result as TXT file.

Target users: Content creators / Researchers / Students / Anyone needing video transcription

The welcome page and side panel UI are bundled in minified JS files, making it difficult to verify all UI elements without runtime execution. However, no login or payment code patterns were found in the static analysis.
The Native Host binary is not included in the source package, so local service behavior is inferred from the extension code.
Cookie usage for accessing restricted content on YouTube/Bilibili was identified but does not constitute a login requirement for the extension itself.

Monetization

No paid features detected

The extension is explicitly described as '免费无限制' (free without limits) in the store listing. No payment platforms, subscription APIs, upgrade prompts, or paywall UI were found in the source code. The extension uses local Whisper AI model via Native Host, with no cloud API calls that would require billing.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension does not implement any login UI or account creation flow. It operates entirely locally via a Native Host (127.0.0.1:8001) and uses a local token for SSE communication with the native service, not for user authentication. The destination services (YouTube/Bilibili) require the user to be logged in to those platforms to access certain videos (e.g., age-restricted content), which the extension handles by reading cookies via chrome.cookies API, but this is not an extension-level login requirement. The core workflow (transcription) can be initiated without any extension-specific account.
