Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
1.8
GPA, above 3 of the 66 other help desk and live chat tools we grade
CustomGPT.ai builds AI agents that answer questions from a company's own websites, documents, help centers and media files, with citations to the source. It is aimed at support, internal knowledge search and onboarding, and it also exposes the same agents through a RAG API. Pricing is by agent, query and document limits rather than per seat.
To get you started, here are 9 things to know about CustomGPT, taken from its own pages and our grades.
- 1
Best for a chatbot that answers from your own docs
CustomGPT.ai builds chatbots that answer from your own content, from $89 a month for 1,000 queries.
- 2
Paid plans start at $89 a month
As its pricing page puts it: $89 per month, billed annually ($99 billed monthly).
- 3
You can try it first
7-day free trial of Standard or Premium
- 4
It runs on Web
Web.
- 5
Agents trained on your content
Feed an agent websites, PDFs, Office files, YouTube videos and audio, or sync from a help center or knowledge base. The page lists more than 1,400 document formats.
- 6
Citations and anti-hallucination controls
Answers cite the sources they came from, and the vendor describes the agents as built to answer only from the content you supply.
- 7
RAG API
Agents can be called from your own code through a RAG API with an SDK, available from the Standard plan.
- 8
A 1.8 GPA, above 3 of 66
That is against the other help desk and live chat tools we grade, on value, the free plan, features, ease of use and platforms.
- 9
Keep it
To replace CustomGPT you would be making an AI model answering your customers from your own help articles. That is not a weekend's work, with an AI app builder or without one.

The report card
Best for a chatbot that answers from your own docs
CustomGPT.ai builds chatbots that answer from your own content, from $89 a month for 1,000 queries. It is not a ticketing inbox or live-chat tool, and white-labelling needs the $449 plan.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | D | $89 a month billed annually for 1,000 queries and 3 team members, which is where the dearest tenth starts. |
| Free plan and trial | D | A 7-day trial on each plan, with no word on a card. No free plan. |
| Features | C | Answers with citations, a RAG API and connectors. It does the chatbot job but is no inbox or live chat, so a smaller job. |
| Ease of use | C | No store rating on record. Content to load and a widget to deploy. |
| Platforms and integrations | B | Web, with Zendesk, HubSpot, Slack, Zapier, Shopify, WordPress, Confluence and Notion plus an API. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who CustomGPT is for
- Fits if you want a chatbot answering from existing docs and help articles
- Works for developers who want a hosted retrieval API over their content
Who it is not for
- Pricey if you are small: 1,000 queries a month at $89, and 5,000 at $449
- Skip it if you need a ticketing inbox or live chat for human agents
- Watch out: white-labelling, website auto-sync and PII removal need Premium
- Watch out: the page doesn't say what happens past your query limit
Good to know
Good for
- Teams that want a chatbot answering from existing docs and help-center articles
- Developers who want a hosted retrieval API over their own content
- Organizations that need citations and SOC 2 Type 2 on the vendor's side
Worth knowing
- There is no free plan; each plan starts with a 7-day trial.
- Standard allows 1,000 queries a month and Premium 5,000. The pricing page does not say what happens beyond that.
- White-labelling, website auto-sync and PII removal need Premium; the AI model selector, priority queries and SSO need Enterprise.
- It answers questions from your content; it is not a ticketing inbox or live-chat tool for human agents.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace CustomGPT you would be making an AI model answering your customers from your own help articles. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 52 of the 66 other help desk and live chat tools grade higher. It costs $1,068 a year.
What you could not
- An AI model answering your customers from your own help articles.
- A search engine with an AI model behind it.
- A chatbot builder hooked into the messaging apps.
- It plugs into other products, Zendesk, HubSpot and Slack among them, and has an API.
What this rests on. CustomGPT’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
