CustomGPT lets you build an AI chat assistant that answers from your own documents and website content, not only from the model’s general knowledge. It is a practical way to turn existing material, such as a guide, knowledge base or course, into an assistant that answers questions without building your own system.
Key features
- Trained on your content: Upload documents or add your site URL for the assistant to learn from.
- Source-grounded answers: Answers focus on the content you added, reducing made-up information.
- Embeddable widget: Put the assistant on your site with a short snippet.
- API: To bring the assistant into your apps and workflows.
- Analytics: To see which questions users actually ask.
Pricing
The base plan starts around $89 to $99 a month, with higher tiers priced by number of assistants, content volume and usage.
Prices can change, so check CustomGPT’s official pricing page before you subscribe.
Pros and cons
| Pros | Cons |
|---|---|

Use cases
- A course assistant: Turn your course materials into an assistant that answers learners around the clock.

Who it’s best for
Trainers, creators and teams with well-documented content who want to turn it into an AI assistant without coding.
Skip it if you only want personal experimentation. General assistants are enough and cost less.
How to get started
Gather organized, up-to-date content first, then build one assistant and test it with real questions before publishing.
