Researched, hands-on test pending
Our top pick: ChatGPT. This write-up is based on research from public sources; we haven't tested it hands-on yet and will update this page when we do. Prices were checked on 31 October 2026 and can change.
Top pick: ChatGPT
- Official site: chatgpt.com
- What it does: Builds a 7-day meal plan around your budget, what's already in the cupboard and fussy eaters, then turns it into a shopping list grouped by aisle.
- Rough UK price: Free; Go £7/month; Plus £20/month (web prices seen 18 Oct 2026)
- Free tier: Yes. Everyday chat is unlimited on Free (fair use), which is plenty for meal plans.
- UK caveats: Supermarket prices it quotes can be out of date or guessed. Check against Tesco, Aldi or Sainsbury's before you trust a total.
- Don't use it if you are: Anyone with serious allergies who needs guaranteed-safe ingredient checks.
Alternative: Google Gemini
- Official site: gemini.google.com
- What it does: Same idea, and handy if you already live in Google Keep and Docs for lists.
- Rough UK price: Free; Google AI Plus £4.49/month; AI Pro £18.99/month
- Free tier: Yes, with a Google account.
- UK caveats: Same caveat on prices: treat costs as rough estimates.
- Don't use it if you are: People who don't want another Google service holding their data.
