-## Definitions
+## FAW
 
-- **AI.** An automated process using the web on behalf of an LLM.
+### Why are AIs distinct from bots and crawlers?
 
-## Clarifications
+AIs process information differently than web crawlers:
+
+* The goal of a crawler is to build a web index, so web developers are incentivised to return **more** rather than **less**: more keywords, more re-phrasings, more elaborations.
+* The goal of an AI is to answer acute questions, so web developers are incentivised to return **less** rather than **more**: short, specific sentences written in such a way that an LLM can make the most use of them.
 
 ### What does "isai" do?
 
+Isai approximates whether the originator of a web request is an AI Bot. It does this by looking at the User Agent string.
+
 ### What doesn't "isai" do?
 
+Isai does not provide a perfectly accurate prediction:
+
+- Some companies, such as Google and Apple, use ambiguous User Agent strings, meaning that the `AI, not AI` decision is, at best, a guess.
+- No company is required to divulge whether their bot is an AI, so false negatives are virtually guaranteed.
+
 ### Why would I want to identify an AI?
 
+You may want to identify an AI if you wish to inject additional and/or different information into your web page for the AI to consume.
+
+For example, you may wish to:
+
+- Provide an overview of the key points of a page in such a way that would be odd for human consumption.
+- Provide a slightly different set of information for the AI to build up context that it might not otherwise have.
