The best AI search engines
The whole value of an answer engine is that you can check it. An unsourced answer is a rumour with good typography.
We look at whether citations point at the sentence that supports the claim, how the engine behaves when the web disagrees with itself, and whether it says so when it does not know.
What we look at
- Citations point to the passage that supports the claim, not the homepage
- Says when sources disagree instead of averaging them
- Admits the gap when there is no good source
- Recent events reflected within hours, not weeks
- Shows what it searched, so you can search it yourself
Helps if you have it: Ten answers to contested questions with every citation resolving to a supporting passage.
