Honestly, not automagically. CookTrace’s bulk importers today handle JSON, HTML, schema.org Recipe markup, and full-backup zips from Mealie / Tandoor / Paprika. Plain text, RTF, and PDF aren’t on that list yet, and there’s no “point at a folder and import everything” mode.

What works today for the same end goal:

• Photo Import — point Trace AI at an image of any recipe (including a PDF you’ve screenshotted) and it extracts it. Fine for a handful, probably painful for hundreds.
• Trace AI chat — paste the recipe text into the assistant and ask it to create a recipe. Same idea, no image step.

A proper “scan this folder/file(s), let the AI structure each one, dedupe, drop them in” is a reasonable feature… I will consider for a future enhancement if not too complicated to incorporate.
