When CustomGPT.ai is the right choice
CustomGPT.ai's strength is capacity: 5,000 documents per agent on Standard and 20,000 on Premium, with up to 300 million words of storage and 10–25 agents. If you're indexing a very large internal document library across many separate agents and only expect modest question volume, that trade-off can make sense.
When a website AI agent is better value
If your agent sits on your website answering customers, question volume is usually the constraint, not storage. CustGPT gives you several times more questions per dollar, plus built-in actions, human handoff, lead capture and a choice of premium models. Compare them in detail in CustGPT vs CustomGPT.ai.
How to pay less for CustomGPT.ai
- Pay yearly — Standard drops from $99 to $89 a month and Premium from $499 to $449.
- Estimate real query volume first — the jump from 1,000 to 5,000 queries is a jump from $99 to $499.
- Consolidate knowledge where you can, so fewer agents cover more questions.
