Control your mobile app from ChatGPT or Claude

You write a sentence in ChatGPT or Claude — “add a Recipes section with five entries” — and the section appears in your app. That’s what the MCP server enables, available from the entry-level plan at €19 per month. Here is how it works, what you can ask for, and what AI will not do.

The real bottleneck for an app is almost never technical. It’s content. An app launches in a few days and dies in three months, for lack of someone to update it on a Tuesday evening.

This is the problem solved by the AI features introduced at Maymoune. They are not there just to look modern : they make sure the app has something fresh to showcase, without spending your evenings on it.

The three content sources, which combine

A Maymoune app is populated in three ways, and there is no need to choose : all three work at the same time.

• What you already have, connected — your website, your store, your channel, your podcast feed, your calendar. You publish there as usual, and the app follows.
• What you create in the back office — sections, items, photos, news, products. You do it yourself, without an external provider.
• What AI produces — texts, translations, entire sections, and content generated directly inside the app.

The third is the new addition : it didn’t exist at Maymoune before, and it is the one that changes the publishing pace.

An MCP server, in plain English

MCP is a standard that allows an assistant like ChatGPT or Claude to act on an external tool, instead of just chatting. Without it, the assistant drafts a text that you then copy manually. With it, it places the text in the right spot itself.

In concrete terms : you connect your app to your assistant once. Then, you talk to it normally. “Create an Our Commitments section with three pages”, “translate the entire menu into English and German”, “write the product sheet for this item from these three lines”. It does it, and you check it in the back office.

What disappears is the back-and-forth : writing in one tab, proofreading in another, pasting into a third. That is where time was lost.

What you can specifically ask it to do

• Create an entire section — with its pages, headings, and texts, from a single-line prompt.
• Write listings and descriptions — products, services, dishes, courses: the descriptions no one ever has time to write.
• Translate — an entire section, all at once, for an international clientele.
• Prepare notifications — the short weekly message, in three versions to choose from.
• Repurpose existing content — turn an article into a short card, a long text into a mobile-friendly summary.

You remain the editor-in-chief: nothing is published without you seeing it first.

The AI extension builder

The other aspect happens inside the application. The AI extension builder generates unlimited content and interactions: games, tools, questionnaires, calculators, mechanics that you describe and it builds.

This is what gives people a reason to reopen the app. A weekly quiz for a club, a simulator for a broker, a calculation tool for a craftsman, a game for a brand: these are precisely the things that used to cost a four-figure quote item, and now become a request written in a single sentence.

You can see what the back-office and these features look like in the back-office presentation.

Available from the very first plan

Managing your app from ChatGPT or Claude is not a feature reserved for large accounts : it is available starting from the €19 per month plan for the PWA web app. The €59 plan adds iPhone and Android apps published on the stores, and the €1,999 plan gives you lifetime access to everything.

Compared to the budget for custom development — a French median of €30,000, detailed in the article on the cost of a mobile app — the difference is not just financial : it is also in how quickly you can change your mind. View the three plans.

What AI will not do

It will not decide for you what deserves to be published. An app filled with correct but generic text interests no one : what retains your customers is what only you know — your products, your habits, your way of working. AI writes fast ; the judgment remains yours.

Nor does it know your numbers, inventory, or business constraints unless you provide them. And it makes mistakes : a miscopied price, date, or allergy needs to be proofread. For regulated content — health, safety, legal information — proofreading is not optional.

Finally, connecting an assistant requires a one-time initial setup. It is not difficult, but it is not magic : the back-office documentation explains it step by step, and support is there to help if you get stuck.

Next step

First, look at what you would need to fill in. Open an app that is already live in your industry, list the sections you would like to have, and count the ones you would never write yourself. These are exactly the ones AI will save you time on.

Frequently Asked Questions

What is an MCP server?

It is a standard that allows an assistant like ChatGPT or Claude to act directly on an external tool instead of just answering questions. Applied to a mobile app: the assistant creates the section, writes the entry, and places the text in the right spot, without any copy-pasting.

Do I need to be subscribed to ChatGPT or Claude?

You use the assistant of your choice, with your own account with its provider. Maymoune provides the integration on the app side; the subscription to the assistant depends on the provider’s offering.

Which plan is this available on?

Starting from the very first plan, at €19 per month, the PWA web app one. It is not an option reserved for higher-tier plans.

Does the AI publish to my app all on its own ?

It prepares and places the content, while you maintain full control over what gets published. That’s the rule to follow : review before publishing, especially prices, dates, and anything related to health or safety.

What can the AI extension creator generate ?

Unlimited content and interactions inside the app : games, quizzes, tools, calculators, and mechanics you describe in a single sentence. This is what gives users a reason to reopen the app every week.

Do you need technical skills to connect your assistant ?

No, but there is a one-time initial setup required. The back-office documentation explains it step by step, translated into 16 languages, with an AI assistant answering questions and human support ready to step in.

Can I translate my entire app with AI ?

Yes, section by section or all at once. It is one of the most cost-effective use cases for a business in a tourist area : the menu or catalog in three languages, completed in an evening instead of waiting for a translation quote.
