What CustomGPT is better at
Larger knowledge bases and bigger organisations: it is built to sit on top of document libraries and internal content, not only a small business's website.
Stay with CustomGPT if
you are training on a large document library, need features built for a bigger organisation, or the bot is not for a customer-facing website.
Questions
Is this a drop-in replacement for CustomGPT?
Not in every respect, and it would be dishonest to say so. Larger knowledge bases and bigger organisations: it is built to sit on top of document libraries and internal content, not only a small business's website. What it replaces is the part that answers customers' questions from your own pages, at a flat price.
What does CustomGPT cost?
$99 a month for 1,000 queries, $499 a month for 5,000. Checked October 2026 against their published pricing — worth confirming, since prices move.
What does this cost?
$49 a month for 1,000 replies, with lead capture included, no per-seat or per-resolution fee and no branding fee. Yearly is 12 months for the price of 10, and new monthly plans get 30% off the first 3 months. Every account starts with a 3-day free trial of every Growth feature, no card.
How long does moving take?
One script tag before the closing body tag, and the addresses of your shipping, returns and FAQ pages. Most shops are answering within a few minutes, and you can leave the old one running while you try it.
