introduced 7 0 ai context from page content many applications need an assistant that understands the page the user is looking at its labels options and visible text not just a generic chatbot the idea is simple wrap page content in a custom tag read the rendered html from the tag body turn that into plain text pass it to createaisession as the system message or as part of it for ai configuration and core functions see ai overview flowchart lr a page template b custom tag body renders b c tag reads generatedcontent c d clean html to text d e createaisession with context e f user asks via inquiryaisession at end execution a custom tag with a body can read thistag generatedcontent everything that was output between the opening and closing tag that string is your page context step 1 wrap the page in your layout or template wrap the main content cf_pageai pagetitle product settings cfoutput h1 product settings h1 p configure shipping and tax options for this store p form label tax rate input type text name taxrate value 8 5 label form cfoutput cf_pageai place the tag file where lucee resolves custom tags for example a mapped custom tag folder lucee calls it as cf_pageai when the

you can add optional metadata page id product name user role the same way as extra lines before page content step 5 ask questions send user input with inquiryaisession the session keeps conversation

set thistag generatedcontent tag merge output the widget itself content after the widget use a marker in the page body for example ai location or split after a known intro block marker ai location

custom tag capture content build system message render widget separate request handler load stored session call inquiryaisession save serialized session again keep serialized data out of the cfml
