📅 Updated October 2026 Prices, limits and terms come from CustomGPT.ai's official pricing page and home page, read on October 13, 2026, in US dollars. Details marked as carried (the query-cost rules for smart actions, payment methods and the trial-support remark) come from an and were not re-read.

You have a website, a help center or hundreds of PDF files, and your visitors ask the same questions every day. That is the problem CustomGPT.ai sells a fix for: a no-code platform that builds an AI agent that answers from your own content, attaches a source link to every answer, and lets you put it on your site or connect it to your tools.

In short: it is worth a trial for a site or support team with documented content that expects up to 5,000 questions a month, and it does not suit people who want a free plan or a fixed cost that does not change as visitors grow. The number to calculate is not $99: the Standard cap is 1,000 queries a month, and every extra query after that costs about 50% more.

What is CustomGPT.ai and who is behind it?

CustomGPT.ai is a platform run by CustomGPT Inc., a US company, with Alden Do Rosario listed as founder in the site's structured data. The home page says it is trusted by 10,000+ organizations, SOC 2 Type II compliant and GDPR compliant, and the company says it does not train any model on your data (carried). These are the company's own claims, not independent measurements.

⚠️ Do not confuse it with custom GPTs: the name suggests the GPTs feature inside ChatGPT, but CustomGPT.ai is a separate platform with its own account, subscription and limits. It builds agents from your content and publishes them on your site or in your tools, and your visitors do not need a ChatGPT account.

CustomGPT.ai features: what do you actually get?

1. Wide data sources with no code

You feed the agent your sitemap, PDF, Word and PowerPoint files (the site claims 1,400+ supported file types), YouTube videos, and audio files and podcasts. The Standard cap is 5,000 documents per agent and 60 million words of storage; the company estimates that 10 million words are about 50 MB, which makes roughly 300 MB of text on Standard.

2. Answers from your content, with a source link

The agent relies on what you indexed and attaches to each answer a link to the source it came from, so a visitor or your team can check it. The home page calls the company #1 in accuracy and anti-hallucination, a claim it does not back with an independent source, so treat it as marketing and test your agent on your real questions before you rely on it.

3. Publishing and integrations

You embed the agent in your site as a widget or LiveChat, or call it through an API, and Standard includes access to the RAG API. The home page speaks of dozens of integrations in one place and of over 100 in its FAQ; an earlier check listed WordPress, Wix, Shopify, Zapier, Google Drive, Notion, Zendesk and Confluence, with Slack on Standard and Premium. If your site runs on WordPress, the connection is ready with no coding. The plans differ in syncing: automatic site sync is listed for Premium and Enterprise, and Standard offers sitemap sync instead.

4. More than 90 languages

The company says it supports more than 90 languages for reading and writing (92 in its FAQ). The agent answers in the language of the question using your content, so the quality of answers in a given language follows the quality of the content in that language that you indexed. Review them yourself before launch.

5. Security and privacy

The company lists SOC 2 Type II, GDPR compliance and SSL encryption, and says in its FAQ that it does not use your data to train any model (carried). The pricing page lists personal-data (PII) removal and logo removal from Premium, and custom single sign-on only on Enterprise.

6. Smart actions that use extra queries

Besides the ordinary answer, the platform offers actions such as document analysis (Document Analyst), answer verification, web search and lead capture. According to the company's documentation as cited in an earlier check, each action is counted on top of the base query, which changes your plan's maths, as the usage section below shows.

💰 CustomGPT.ai prices in 2026: plans, limits and add-ons

According to the official pricing page, paying yearly saves 10% ($89 and $449 a month), and the company accepts credit and debit cards through Stripe and does not accept PayPal or prepaid cards (carried):

Spec	Standard	Premium ⭐	Enterprise
Monthly price	$99	$499	Custom
With annual billing	$89 a month ($1,068 a year)	$449 a month ($5,388 a year)	Contact sales
Agents	10	25	As needed
Queries per month	1,000	5,000	As needed
Documents per agent	5,000	20,000	As needed
Word storage	60 million	300 million	As needed
Team members	3	5	As needed
Logo removal	Not available	Available	Available
Automatic site sync and SharePoint	Not available	Available	Available
Analytics history	7 days (carried)	Full (carried)	Full (carried)

If you need more than your plan's limits, monthly add-ons are paid with the subscription and work immediately:

Add-on	Monthly price	Equivalent
2,500 extra queries	$375	about $0.15 a query
300 million words of storage	$300	about $1 per million words
100,000 extra documents	$100	about $0.001 a document
25 extra agents	$100	$4 an agent
5 extra team seats	$100	$20 a seat

⚠️ Work out the real price of a query: inside the plan a query costs about $0.10 ($99 for 1,000 on Standard and $499 for 5,000 on Premium), and outside the plan about $0.15 through the add-on. Premium gives you no discount on the query price: you pay about five times the price for five times the queries, and the real difference is the logo, the sync and the higher caps.

When does the maths flip in favor of Premium?

Standard with one extra query pack costs $474 a month ($99 + $375) and covers only 3,500 queries, which is $25 less than Premium, which gives you 5,000 queries, logo removal, automatic sync and more seats. So if you clearly expect more than 1,000 queries a month, or need the logo removed, price Premium from the start. If you stay under 1,000 queries, Standard is enough.

What uses up queries, and what happens when you hit the cap?

The company's FAQ says every user message counts as one query, including follow-ups in the same conversation, so a five-message conversation uses 5 queries (carried). Queries and stored words are shared across all the agents in your account, not per agent.

Smart actions count on top of the base query according to the company's action-cost documentation as cited in an earlier check: analyzing one document with Document Analyst adds 14 queries on Standard (15 with the base query) and 9 on Premium (10 with the base query), so 1,000 queries on Standard cover only about 66 document analyses. Answer verification adds 9 queries on Standard and 1 on Premium, and web search adds 3 on Standard, with at most one search per query.

⚠️ The agent stops at the cap: the company says the system stops answering questions when the query limit is reached, and stops indexing new data when the word limit is reached (carried). Your visitors see a temporary unavailability message until capacity renews or you upgrade, so do not put an agent on a busy site without monthly usage monitoring.

⚖️ CustomGPT.ai vs the alternatives: where it wins and where it falls behind

Tool	Published price (monthly)	Counted unit	Free plan
CustomGPT.ai ⭐	$99 (Standard) and $499 (Premium)	1,000 and 5,000 queries a month, 10 and 25 agents	No, a 7-day trial with a card
Chatbase	$40 (Hobby), $150 (Standard) and $500 (Pro), and 20% off yearly	700, 4,000 and 15,000 message credits a month	Yes per an earlier check: 50 credits, and agents deleted after 14 days of inactivity (not shown on the page text read)
SiteGPT	$59 (Starter), $129 (Growth) and $429 (Scale), and $39, $79 and $259 billed yearly	4,000, 10,000 and 40,000 messages a month	No, a 7-day trial with a card

The units differ, so do not compare the numbers directly: CustomGPT.ai counts a single query (and smart actions add to it), Chatbase counts message credits whose use depends on the model, and SiteGPT counts messages with the GPT-4.1-mini model or fewer messages with GPT-4.1 (any mix; GPT-4.1 messages count about ten times as much). CustomGPT.ai wins on source capacity, number of agents and security documentation on the first plan, and falls behind on the query cap, the lack of a free plan and logo removal being limited to Premium.

🎯 Who is CustomGPT.ai for, and who is it not for?

✅ It suits you if you:

Run a site or help center with documented content visitors want to ask about
Are a support team that wants fewer repeated questions, with answers that cite sources
Have many internal documents and want your team to ask them in natural language
Have no developer and want an agent that works without coding
Expect a question volume below 5,000 a month

❌ It does not suit you if you:

Want a permanent free plan or a very small budget
Expect thousands of questions a day from site visitors
Want to choose the AI model yourself without Enterprise
Usually pay by PayPal or a prepaid card

✅ Is your content ready and your question volume known?
Try the agent for a week on your visitors' real questions before you pay the first dollar

🛒 How to start with CustomGPT.ai, step by step

Open an account and start the trial. You need your name, email, password and a payment card, and the 7-day period starts with the features of the plan you chose; the chosen plan is charged automatically after it ends.

Create an agent and add knowledge sources. Add your sitemap, files or YouTube videos, and wait for indexing to finish before testing.

Test the answers and check the sources. Ask the most frequent questions your visitors ask, and check the links attached to each answer.

Publish the agent. Place it as a widget or LiveChat on your site, whether it is on traditional hosting or on a website builder, or call it through the API.

Watch the usage and decide before the trial ends. If you do not want the plan, open the billing page in your account and press “Cancel Subscription” before the seven days end, otherwise the subscription is charged.

🏆 The verdict: is CustomGPT.ai worth it in 2026?

It is worth a trial for a site or support team whose content is documented and whose question volume is known and under 5,000 a month, and it is not worth it for people who want a free plan or expect unpredictable traffic. Its real strength is an agent that answers from your content with sources and enterprise-style security without writing a line of code, and a first plan with 10 agents and the RAG API.

But the drawbacks are plain: a 1,000-query cap at which the agent stops, extra queries about 50% more expensive, logo removal at $499 a month, a trial that converts automatically after 7 days, and a refund limited to the current subscription charge. Start with the trial, watch the usage in its first week, and compare the result with Chatbase and SiteGPT pricing before any annual payment.
