ChatWidget vs CustomGPT.ai

Last verified 27 August 2026

CustomGPT.ai and ChatWidget both show where an answer came from. The difference is what happens when the answer is wrong: ChatWidget also shows the passages it rejected, sells from a live WooCommerce catalogue and hands the cart to your checkout. CustomGPT.ai has SOC 2, named customers and larger plan limits, and is the safer choice for a documentation assistant that is not a shop.

What CustomGPT.ai does better

  • They make our argument, and they shipped it first. Every answer carries a link to its source, and Anti-Hallucination and Citations and Sources are listed as features on every plan, not as an enterprise add-on.
  • Proof at a scale we cannot match: Trusted by 10,000+ organizations worldwide, with the United Nations, Adobe, Dropbox and Medtronic among the named logos. We name no customers, because we do not yet have ones we can name.
  • SOC-2 Type II and GDPR compliance. We hold neither, and our security page says so.
  • Headroom, if you need it. Premium carries 5,000 monthly queries, 25 agents and 300M words of storage, well past what this product's published plans allow.

Where this one is stronger

  • A citation names the passage that was used. A trace also shows the passages that were not: every chunk retrieval considered, the score on each, and the reason each rejected one fell out. When an answer is wrong, what you need is almost always in the chunks that did not make it.
  • A measured loader size, published on the widget page and held under an 8 KB budget the build enforces, and no layout space reserved on your page.
  • Published plan limits, including tool timeout, rate limit and version-history depth, and a named storage region with the hop out of it disclosed.
  • A lower entry price. Their smallest paid plan is $99 a month for 1,000 queries; ours is on the pricing page, which prints the live figure rather than one copied into a comparison.

This is the closest comparison on the site, and the one where we are least able to claim the argument as ours. CustomGPT.ai’s headline is “Every AI answers questions. Create one you trust.” That is the same sentence we would write, and they are writing it to ten thousand organisations while we are writing it to you.

So the useful question is not who says trust. It is what each product actually shows you when an answer is wrong.

A citation is a link on the answer. It tells you which document the assistant drew on, which is genuinely useful and is more than most of this category offers. What it cannot tell you is anything about the passages that were not used, and that is where a wrong answer usually lives. Retrieval returns candidates and scores them. Some clear the threshold and reach the model; the rest are dropped. A citation only ever describes the survivors.

A trace is the whole set. Every chunk retrieval considered, the score on each, which were selected as context, and a reason on every rejection. That is what separates two failures that look identical from the outside: the right document was never retrieved, or it was retrieved and misread. The first is a chunking or indexing problem and the second is a prompt or model problem, and no citation on earth distinguishes them, because in both cases the answer cites something.

One claim of theirs we could not stand up: their site describes third-party verification as the number one product for anti-hallucination technology, and we could not find the third party named on the pages we read. That is not an accusation, the verification may well exist somewhere we did not look, but a comparison page should say which claims it checked and which it could not, and this is one it could not.

Pick CustomGPT.ai if you want a mature product with a large installed base, formal certifications, and a source link on every answer, and if 1,000 queries a month at $99 fits the shape of your traffic.

Pick this one if you expect to spend time on why an answer was wrong rather than where it came from, and if you would rather read the retrieval than trust it.

Pricing: Standard $99/month for 1,000 monthly queries, 10 agents and 3 team members; Premium $499/month for 5,000 queries, 25 agents and 5 members; Enterprise on application. Annual billing brings the first two to $89 and $449., checked 27 August 2026.

Questions people ask when choosing between the two

Is CustomGPT.ai better than ChatWidget for an online store?

For a store, ChatWidget: it reads live price and stock from a WooCommerce catalogue and puts a cart in the chat, which CustomGPT.ai does not do. For a documentation or support assistant with no shop behind it, CustomGPT.ai is more mature and holds certifications we do not.

Does CustomGPT.ai show why an answer was wrong?

It links each answer to its source document. It does not show the passages that were retrieved and rejected, which is where most wrong answers are explained. ChatWidget shows both.

Which is cheaper?

ChatWidget's smallest paid plan is ₹999 a month, and the Trial plan is free and does not expire. CustomGPT.ai's smallest paid plan was $99 a month for 1,000 queries when we checked, and the page states the date.
