Claude Code showed they didn't need a €100/month supplement
Recipes from photos, nutrition from the USDA, a weekly plan and shopping list. Their meal data showed they already get most vitamins, and 2 weeks of symptom logs point to tomatoes as a first suspect.

Result First suspect for their symptoms: tomatoes
“I was recently researching whether I needed to invest €100/month in AG1, but after analyzing my current meal plan, it turns out I'm already getting most of my vitamins.”
Spotted: found in the wild. Details are as reported by the source above and have not been independently verified.
What they did
Adds meals to a folder from cookbook photos, PDFs or websites, and the agent pulls nutrition data from the USDA API. Each week it plans meals, generates a shopping list by category and reports protein and micronutrients. They also log digestive symptoms and eczema flare-ups for it to analyse.
How it went
The analysis showed they already get most of their vitamins, so they skipped a €100/month supplement and made small tweaks such as adding seeds and a kiwi. From 2 weeks of symptom data, the first suspect is tomatoes, and they’ve started a structured elimination diet. They stay in the loop: it’s no good at the analysis without them.
Try it yourself with Claude Code
Here are my recipes: [folder]. For each one, get the nutrition data from [USDA API or another source] and save it. Then plan next week's meals from these recipes, [number] servings a day, and give me a shopping list grouped by aisle plus a report of my daily protein, fibre and key vitamins and minerals against recommended amounts. Suggest the smallest changes that would close any gaps.

Days or months after highlighting a line, it appears on the display on their dresser. Claude Code wrote the backends for the e-ink screens, showing a random quote with its book cover, 100% local.
The Android apps for their old Brother printer were terrible and ad-ridden. With Claude Code in the browser on their phone, they built their own print page, one of dozens of little family apps.
The recovered files were malformed. Claude Code helped work out that each was a metadata header, a thumbnail and the real image stuck together, then wrote a script that split them, metadata intact.
About 15k pages of discovery stood between a solo practice and a summary judgment motion. Claude ran OCR, built embeddings and search scripts, then found evidence for each assertion, with traces to check.
Markdown files should just open, so they asked Claude Code for a viewer. It opens instantly: faster, they say, than any other macOS app, and faster than Bitwarden's Chrome extension shows its fill menu.
Migrating a password reset flow, Claude Code and Opus produced code on par with a mid level developer. It needed close supervision throughout, and cost roughly 2 months of Pro subscription for about half a day's work.
