The custom GPT alternative for when the assistant has to live on your site
Building a GPT with your documents is the fastest and cheapest way to prove the idea works, and plenty of people rightly stop there. The problem is that this assistant lives inside ChatGPT: your customers would have to go and find it, with their own account, away from your site and your brand.
The same knowledge, but on your site, with your brand, citing sources and with analytics on what people ask you.
For internal use — your team consulting manuals, procedures or technical documentation — a custom GPT is an excellent solution and you probably need nothing more. The moment the person talking to the assistant is a customer, the model breaks: it is not on your site, it does not carry your brand and you never find out what people are asking.
Why teams start looking for a ChatGPT custom GPTs alternative
It lives in ChatGPT, not on your site
Your customer would have to leave your page, go into ChatGPT and search for your GPT to ask you something. Nobody makes that journey, least of all from a phone at eleven at night.
Your brand disappears
The conversation happens in someone else’s interface, with their logo and their design. At the exact moment the customer is deciding whether to buy from you, you are not on the screen.
You have no idea what people are asking
There is no dashboard with the most repeated questions, or with what the assistant could not answer, or with which conversations ended in a sale. You lose the most useful part of having an assistant.
Getting it onto your site is a development project
It can be done through the API, of course. But at that point you are no longer configuring a GPT: you are building and maintaining a product, with its widget, its indexing, its cost control and its monitoring.

|---|---|---|
| Where the conversation happens | Inside the ChatGPT interface | On your site, on your domain and with your design |
| What the customer needs | Their own account and to know your GPT exists | Nothing. They open your site and ask |

| Business analytics | Not designed for this | What people ask, what it could not answer and which conversations led to contact |
| Verifiable answers | Depends on the instructions you wrote | Always cites the source. If it is not in your documentation, it says so |
| Industry knowledge | Whatever you put in the instructions | Verticals configured for ecommerce, technical support, clinics and restaurants |

When to switch and when not to
Stay with ChatGPT custom GPTs if…
- The assistant is for internal use and your team already works with ChatGPT daily.
- You are validating whether the idea adds value before investing in anything.
- Your documentation rarely changes and you do not mind re-uploading it by hand.
- You do not need to know what gets asked or to measure whether conversations turn into business.
Switch to Soamee if…
- The person who needs to talk to the assistant is your customer, and your customer is on your site.
- You want the conversation to happen under your brand and on your domain.
- You need data: what people ask, what fails and what ends in contact or a sale.
- You want answers to cite their source because there are customers or patients on the other side.
