It looks like your query "#withai @extract = browser@zip" might be a shorthand or command-style prompt related to AI-assisted web data extraction (scraping) using browser-based tools, possibly outputting to a ZIP archive. Based on current tools and trends, I'll interpret this as a request for guidance on extracting website data with AI—no coding required—and packaging it (e.g., as a ZIP of CSVs or spreadsheets). If that's not what you meant, clarify!
