What is this?
Honest Dousha Bao (诚实豆沙包) is a Chrome extension that checks Bilibili review videos for hidden sponsorships: click the floating bun on a video and in about 20 seconds you get an S/A/B/C sponsorship index with timestamped callouts.
Is this a website or something I install in my browser?
It's a browser extension, not a website or a standalone app: once loaded in Chrome, it adds a draggable bun widget to Bilibili video pages, and its toolbar icon opens a side panel for reading the full verdict.
How do I get the extension into Chrome?
Download the release zip and unzip it to a permanent folder (deleting it breaks the extension), open chrome://extensions, enable Developer mode, click 'Load unpacked' and select that folder; the bun then appears on Bilibili video pages.
Do I need my own API key to use it?
Yes - the open-source build includes no shared key, so you bring an API key from an LLM provider: DeepSeek by default (pay-per-use, very cheap per check), or OpenAI, Anthropic, Google Gemini and Alibaba Qwen.
Can I actually trust its verdicts?
Every verdict is AI analysis of the video's subtitles, offered for cross-reference only - misjudgments are inevitable, and a low grade is not an accusation of any uploader or brand.
What do the S/A/B/C grades mean?
C is clean (a genuine review that covers pros and cons), B is basically trustworthy with a minor lean, A means the stance hugs the vendor's line, and S means sponsorship maxed out - stealth comparisons, rigged rankings, scripted moments.
Can I post its verdicts in comment sections to warn others?
No - the README explicitly asks you not to use results as evidence to criticize uploaders in comment sections, nor for personal attacks or commercial disputes. Treat them as personal reference, not ammunition.
