Writing Assistance Apis

Teaches Claude how to wire up the browser's built-in Summarizer, Writer, and Rewriter APIs in your JavaScript or TypeScript web app. You'd reach for this when you want on-device text generation without sending data to the cloud: checking availability, handling model downloads with progress UI, creating sessions with the right options, streaming or batch output, and dealing with permissions-policy constraints in iframes. The procedures walk through feature detection, choosing the right API surface for your task, building guarded session wrappers, and wiring up fallback UX for unsupported devices. It's opinionated about keeping these APIs for their intended purpose and switching to Prompt API when you're really building a chatbot. Includes a find-targets script, reference docs, and explicit TypeScript templates.
