100-word summary
Microsoft just made it easier to build AI chatbots that actually know your company's policies. Its new Retrieval API lets developers pull answers from SharePoint and other Microsoft 365 sources without building custom search tools. The catch: results cap at 25 documents per query, and files can't exceed 512 MB. What makes this different from dumping files into ChatGPT? Built-in permission checks mean your expense bot won't accidentally quote HR documents you're not supposed to see. Pricing switched from requiring a Copilot license per user to simple pay-per-call. The real test is whether SharePoint's notoriously messy folder structures will surface the right answers or just the most recent PowerPoint deck.
