What it solves

VideoAdGuard is a browser extension designed to detect and skip integrated advertisements (sponsored segments) within Bilibili videos. It helps users avoid promotional content by automatically identifying the specific time intervals where ads appear.

How it works

The tool analyzes video content using a combination of text and audio analysis powered by Large Language Models (LLMs). The process follows these steps:

1. Content Extraction: It retrieves video subtitles, titles, and pinned comments. If no subtitles are available, it downloads the audio stream and uses the Groq Whisper API for speech-to-text conversion.
2. Cache Check: It first checks a local 24-hour cache and a community-driven cloud cache to see if the ad segments for that video have already been identified.
3. AI Analysis: If no cached result is found, the subtitles or transcribed audio are sent to a configured LLM (such as DeepSeek, OpenAI, or local Ollama models) to determine the exact start and end times of the advertisement.
4. User Interface: Once identified, the extension adds a "Skip Ad" button to the player and marks the ad segments in red on the video progress bar.

Who it’s for

Bilibili viewers who want to save time and avoid sponsored segments in videos, as well as users who prefer using their own AI API keys for content filtering.
