What NEXBot is
NEXBot is a platform for building customised chatbots. You construct your own GPT model without paying a subscription, and the site states you get 500 free messages to work with. Files can be added to give the bot knowledge, and that upload step is the main lever over what it knows and how it answers. Once a bot is built it can be shared with other people, who can reach it without holding an account of their own, or embedded directly into your application. The examples the site gives are customer service bots answering common questions, shopping assistants on an e-commerce site, and learning companions inside an education app. The free tier is the headline feature, but the site was not responding when this entry was checked.
What you can do with it
- Build a custom GPT model with no subscription fee
- Upload files to give the bot its knowledge base
- Test it against your 500 free messages
- Share a link, or embed the bot in your own app
Who it is for
- Anyone who wants a FAQ style bot without a subscription
- Site owners who want a chat widget trained on their own material
- Small teams testing whether a custom bot reduces support load
What to watch out for
The site was returning an error when this entry was checked, so availability is uncertain and you should confirm it is live before planning anything. Even when it works, 500 free messages is a testing allowance rather than a production quota, and heavier use will need a paid plan. Answer quality depends entirely on the material you upload, so a thin knowledge base produces thin answers. Because the bot runs on someone else's platform, changes to their terms or their model can alter how your bot behaves with no notice to you.
