RecipeSage turns bookmarks, screenshots, PDFs, and cookbook photos scattered across a household into one searchable cookbook on a server you run. Paste a link, drop in a photo of a cookbook page, or upload a document, and a complete recipe with ingredients and steps appears, ready to edit. Drag dinners onto the calendar for the week, repeat the regulars on a schedule, and print the plan for the fridge door. Send a planned recipe to the shopping list and its ingredients land sorted by grocery aisle, near duplicates merged, quantities added together. Cook mode puts ingredients and steps side by side in big type, ticks steps off as you go, rescales servings mid-recipe, and keeps the tablet awake through the sauce. Nutrition panels track calories, macros, vitamins, and minerals per serving, filled automatically when you paste a label. Collections move in from Paprika, Mela, Tandoor, Pepperplate, Evernote, and Notion, and leave again as PDF or JSON-LD whenever you ask. Share a cookbook with family, plan meals together, and take the whole library offline into the grocery store, where it syncs again when the signal returns. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.
