Worth knowing before you start

A custom chatbot sounds ideal, but most teams assume it needs engineers and weeks.

The takeaway

1. Setup is genuinely no-code

Frequently asked questions

Can you really build a chatbot without code using CustomGPT.ai?

Yes. We built a working chatbot on our own docs in under an hour: upload documents or point it at your sitemap, and it answers from your content with citations. No engineering required.

How accurate is CustomGPT.ai?

Strong on content that exists in your uploaded sources, and it cites where answers come from. Like all RAG chatbots, it degrades when your docs are outdated — the bot is only as good as the knowledge base.

Who is CustomGPT.ai best for?

Businesses that want a support or docs chatbot without hiring developers. If you have engineering resources and need deep customization, building in-house on an LLM API gives more control.
