Overview

CustomGPT and Chatbase are platforms that allow you to build chatbots powered by large language models. Both tools let you customise your chatbot using your own documents or knowledge base so that you can provide accurate answers to your users.

CustomGPT

• Enables you to upload PDF files, websites and other documents to train a custom GPT chatbot.
• Focuses on privacy and data control — your training data stays in your account.
• Offers multi‑channel deployment, including web widgets and API access.

Chatbase

• Allows you to build AI chatbots using your website content or uploaded files.
• Provides a simple interface to customise responses and manage user questions.
• Integrates easily with websites via an embed script, making deployment quick and straightforward.

Which Should You Choose?

Both platforms help you create bespoke chatbots that answer questions based on your content. If you need fine‑grained control over training data and plan to integrate across multiple channels, CustomGPT offers more flexibility. If you value rapid deployment and an easy embed, Chatbase is a great option. Your choice depends on the depth of customisation required and where you plan to deploy the chatbot.
