What is CustomGPT.ai?
You upload or connect your content, such as websites, help centres, PDFs, Office files, YouTube videos and audio, and CustomGPT.ai builds an AI agent that answers questions based only on that material. It supports 1,400+ document formats and 90+ languages.
Key features
Train on your own content
Add sitemaps, knowledge bases, helpdesks, documents and media. The agent keeps its answers grounded in what you provided.
Citations and anti-hallucination
Each answer links to the source it came from. The company promotes its anti-hallucination technology as a core feature on every plan (a vendor claim worth testing with your own content).
Deploy anywhere
Embed the agent on your website, use it internally for staff knowledge search, or connect it to other tools through integrations and API.
Multilingual answers
Customers can ask in 90+ languages and get answers drawn from your content.
