Chatbot or ChatGPT assistant: which one for your app?

Two AI assistants can answer your customers in your app: the ChatGPT assistant and the chatbot on your content. One follows your instructions, the other reads your pages. Here’s how to choose, depending on your business.

Both look alike on screen: a conversation area, a question, an answer. But they don’t work the same way, and they don’t do the same job. I show them side by side, with two real conversations in our demo.

The difference in one sentence

The ChatGPT assistant knows what you write in its instructions. The chatbot knows what’s published in your app, and keeps it up to date on its own.

What they have in common

• They answer at any hour, even when you’re closed.
• They usually answer in the customer’s language.
• They take on your app’s colours and fonts.
• They remind users that AI can make mistakes, and each customer can report a conversation.
• They’re added as a section, which you place wherever you like in the menu.

In both cases, you stay in control: you decide what they say, and you can remove them from the menu at any time.

Choose the ChatGPT assistant if…

• You want an adviser who guides, reassures and suggests, with a very personal tone.
• Your key information fits in a few lines: hours, prices, offers, rules.
• You already have an OpenAI account, or you’re ready to open one.

It’s all covered in the article on the ChatGPT assistant.

Choose the chatbot if…

• You publish a lot: treatments, products, news, events, addresses.
• You want every answer to link to the right page in the app.
• You sell a subscription and want different answers for your subscribers.

Why not both?

Both can live in the same app. The chatbot answers precise questions about your content, the ChatGPT assistant plays the adviser. Give them clear names in the menu, for example “Find information” and “Ask for advice”.

Three real-life examples

• A spa: the chatbot for the treatment menu and lengths, the ChatGPT assistant to suggest a ritual based on today’s mood.
• A tourist office: the chatbot for places and events, the assistant to build a tailor-made day.
• A store: the chatbot for product pages, the assistant to find a gift idea.

How much it costs

Your app stays on one of the three plans, detailed on the pricing page:

• Starter, €19 a month: your web app, installed from a link or a QR code.
• Ultra, €59 a month: the same, plus the iPhone, iPad and Android app on the stores.
• Ultra lifetime, €2,999: a one-time payment, with publishing on the App Store and Google Play included.

My advice: start with the ChatGPT assistant if your content is still light, then add the chatbot once your sections are well filled. Plan details are on the pricing page.

Also worth reading: the MCP protocol made simple. Other questions are answered in the FAQ.
