New to this? What's a prompt?

A prompt is the message you send to the AI tool. Copy the one on this page, put your own details where it asks, and read the answer before you act on it.

Prompt

Recreated prompt

The source didn't share its exact prompt, so we wrote one from what it describes. The result shown is the source's, not ours.

What the prompt labels mean

The person didn't share their exact words, so we wrote this from what they described. We haven't tested it, and they didn't use this exact version.

Read this photo of a handwritten recipe card and return a structured recipe: title, ingredients with quantity and unit as written, numbered steps, prep, cook and rest times, oven temperature and equipment. If anything isn't on the card, leave that field empty instead of guessing, and tell me how confident you are in the reading.

Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish.

Goal: Digitize my family's recipe cards so I can plan meals and build shopping lists from them.

Questions to ask me first:
- What formats are your recipes in?
- Which fields matter most to you?
- How do you want the shopping list delivered?

Inputs (fill in or confirm):
- Recipe images: [PHOTOS OR PDFS]
- Fields to capture: [INGREDIENTS, STEPS, TIMES, OVEN TEMPERATURE]
- Week to plan: [NIGHTS AND RECIPES]
- Shopping list format: [BY AISLE, TEXT OR PRINT]

Rules:
- Leave a field empty rather than inventing a value.
- Keep quantities as numbers with separate units so they can be combined.
- Flag any card you can't read clearly.
- Save nothing until I've reviewed it.

Checkpoint: Show the first two recipes for review before processing the rest.

If you get stuck: If a card is unreadable or isn't a recipe, flag it and move on.

Verify before you finish: Every saved recipe matches its card, and the shopping list totals add up.

Output: Structured recipes plus a combined shopping list grouped by aisle.

Done when: My recipe cards are searchable and next week's shopping list is ready.

Outcome

Ben McOsker's family recipes were scattered across index cards in a drawer, including decades-old handwriting and cards from defunct meal services, and typing them in was never going to happen. Using Claude Code, McOsker built Trivet, a recipe box for one household: a photo of a card, printed recipe or PDF goes to Claude in a single call and comes back as a structured recipe with ingredients, quantities and units, numbered steps, times, oven temperature and equipment. The instructions tell Claude that a missing cook time should come back empty rather than invented, a confidence field flags blurry cards or pages that aren't recipes, and nothing saves until McOsker reviews and submits it. After planning a dinner for each night, the app combines quantities across meals, groups the shopping list by aisle and texts it to McOsker's phone.
