ChatGPT vs Gemini for groceries: which AI assistant to choose?
There is no single assistant that suits everyone for groceries: it depends on what you need. On 9 November 2026 the Swiss App Store shows ChatGPT Go at CHF 7.00 and Plus at CHF 20.00, Claude Pro at CHF 18.00, while Google lists Gemini AI Plus at CHF 5 and AI Pro at CHF 17 a month. Here you find plans, receipts, data and availability of the four assistants, with sources.
There is no single assistant that suits everyone for groceries: it depends on what you need. For a list or a menu, the free plans of ChatGPT, Gemini, Claude and Copilot are enough; a paid plan adds more usage, more memory and extra features, not this week’s promotions. In November 2026 the Swiss prices in CHF are: ChatGPT Go 7.00 and Plus 20.00, Claude Pro 18.00 (App Store), Google AI Plus 5 and AI Pro 17, Microsoft 365 Single with Copilot 9.95 per month. Rappn’s connector for ChatGPT and Claude is coming soon: join the waitlist to be among the first to try it.
Updated November 2026. Sources: ChatGPT plans and the Swiss App Store listing (OpenAI); pricing, the Swiss App Store listing and supported countries (Anthropic); Google AI plans, usage limits and countries and languages (Google); Copilot for individuals, Copilot free and Microsoft 365, prices in the Swiss Microsoft Store and the Copilot privacy FAQ (Microsoft), all read on 9 November 2026.
ChatGPT vs Gemini for groceries: what really changes?
For everyday tasks (a list, a menu, a comparison of two recipes) the four assistants do similar things, so the choice depends on something else: where your data already sits, how much you use the assistant and which plan you need. Gemini works closely with Google services, ChatGPT and Claude have their own apps and connectors, and Copilot is built into Windows and Microsoft Edge. None of the four knows this week’s promotions in your canton on its own: they only find them if they open pages that show them, and the guide to ChatGPT and grocery deals explains why that needs checking.
Whichever assistant you choose, here is what the app already shows: the current promotions of seven Swiss retailers, your list and alerts for products you follow. Tap the tabs.

How much does ChatGPT cost in Switzerland, and the others?
| Assistant | Free plan | First paid plan (9 November 2026) |
|---|---|---|
| ChatGPT (OpenAI) | Yes, with limits | Go: CHF 7.00; Plus: CHF 20.00 (Swiss App Store, in-app). The plans page we read shows no amounts. |
| Claude (Anthropic) | Yes, with limits every 5 hours and every week | Pro: CHF 18.00 per month (Swiss App Store); on the website USD 20 per month, or USD 17 per month with an annual payment of USD 200, tax excluded. |

According to OpenAI’s Help Centre, ads appear on the Free and Go plans, not on Plus, Pro, Business, Enterprise and Edu: the details are in the guide to ads in ChatGPT. If you pay for one, note the renewal date: the guide to forgotten subscriptions shows how.
Do you need the paid version for groceries?
Almost never for a list or a menu. The providers describe the paid plans as being for other things:
- ChatGPT: Go offers more uploads, images, voice and longer memory than Free; Plus adds features such as projects and scheduled tasks (OpenAI’s plans page).
- Claude: the free plan already includes web search, memory and connectors; Pro has more usage every 5 hours and every week (Anthropic).
- Gemini: AI Plus offers double the free limits and AI Pro four times as much; the context window grows from 32,000 to 128,000 and to 1 million tokens (Google).
- Copilot: the free plan answers with web search; with a personal account you add history, images and voice (Microsoft).
How many free messages you get each day is not a fixed number: Google says the limits depend on complexity, models and chat length, and that it can change them without notice. Try the free plan for two weeks first.
Which one reads a receipt best?
| Assistant | What it says about images | Source |
|---|---|---|
| ChatGPT | You can take or upload a photo, for example to transcribe a handwritten recipe | Swiss App Store listing |
| Claude | Analyses photos, PDFs and screenshots and extracts the text | Swiss App Store listing |
| Gemini | Lists the analysis of large files among the tasks that use the most of your allowance | Google’s help page on limits |
| Copilot | Vision: visual help from your screen or camera, with different limits per plan | Microsoft’s Copilot page |
Run the test yourself: upload the same receipt to two assistants and compare lines and total with your card. Cover your name, loyalty card and card digits first (more in the guide to analysing grocery spending with AI).
Which one protects your data best?
There is no winner: the settings are what count, and each provider has its own. For personal accounts:
- ChatGPT: chats can be used to train the models until you switch off “Improve the model for everyone”; there is a temporary chat (guide to personal data).
- Claude: on Free, Pro and Max, chats can be used for training unless you switch off the option to help improve the AI models (guide to Claude’s connectors).
- Gemini: with activity saving on, chats stay in your Activity; with it off, they are kept for 72 hours and do not train the models, except for feedback (guide to connected apps). In Switzerland Google asks for a minimum age of 18.
- Copilot: if you are signed in you can decide whether conversations are used to train Microsoft’s models; when signed out, under 18, or with Copilot inside Microsoft 365 Personal and Family, Microsoft says it does not train on the conversations (Copilot privacy FAQ).
Do they work in Switzerland and in English?
- Gemini: Switzerland and English are on Google’s list (9 November 2026).
- Claude: Switzerland is on Anthropic’s list of countries.
- ChatGPT: the app is in the Swiss App Store, and OpenAI’s Help Centre names Switzerland among the markets where ads appear (9 November 2026).
- Copilot: Microsoft sells the Microsoft 365 plans with Copilot in Switzerland and says features and availability vary by region: check the language in the app’s settings.
Which one to pick if…
- …you already use Gmail, Calendar and Keep: look at Gemini and its connected apps.
- …you want to connect other services: ChatGPT and Claude have apps and connectors, with different plan rules in the dedicated guides.
- …you work on Windows or with Edge: Copilot is already there.
- …you just want to try it: start with a free plan.
- …you need this week’s shop: none of the four is enough without a dated source: look at the current promotions and use the assistant for the rest.
How to check an answer about prices
- Ask for the source and the date of every price.
- Check the canton and the validity period of the promotion.
- Compare the price per kilo or per litre: see the guide to unit prices.
- Open the promotion page before you go to the shop.
