官方常见问题
- Where is Face Search AI available?
- Search is not available in every region. If it is unavailable where you are, you will see a notice on the search page — the rest of the site works normally. Our Terms of Service set out what is and is not allowed here.
- How accurate is it?
- On clear, front-facing photos, strong matches (90+ confidence) are correct the overwhelming majority of the time. Accuracy drops with heavy blur, extreme angles, or very low resolution, which is why every match carries a confidence score instead of a flat yes.
- What do you do with the photo I upload?
- It’s converted to a numeric code and matched against public web images by the search providers we use. On our side the photo is deleted automatically within about 15 minutes. It is never added to a searchable collection and never used to train models.
- Can I remove my own face from results?
- Yes. Free and available to everyone whether or not you have an account. Verify that the face is yours, and matching results are suppressed across all plans, including paid ones.
- What sources do you search?
- Millions of public websites: news archives, public social profiles, forums, company pages, event galleries, and the open web at large. Never private or logged-in content, and never surveillance or government databases.
效率与决策 · 常用提示词
下面这些都能直接复制，把里面的变量换成你自己的情况就能用。
- 学习法选择：这个方法适合什么材料对比费曼、间隔重复、刻意练习、主动回忆的适用边界。
- 状态低迷：先分清是累、是乱、还是怕三种低迷对应三种处理方式，避免用「休息」一刀切。
- 情绪记录：记触发点，不记感受日记用结构化字段记录情绪事件，找出可干预的模式。
