Looking for a CustomGPT alternative?
CustomGPT.ai is a capable platform — most people comparing it are really comparing three things: whether there is a free plan, what the paid plans cost, and how much room they include. Here is AgentoGPT on exactly those points, side by side.

Why people switch
A price that starts lower
Both platforms do the same core job — AI agents trained on your content, with citations. AgentoGPT's paid plans start at $19/mo instead of $99/mo, and the top published plan is $299/mo instead of $499/mo.
A real free tier — no card, no countdown
CustomGPT.ai offers a 7-day trial of its paid plans and asks for a credit card up front, then charges when it ends. AgentoGPT's free plan is free forever: 1 agent, 5 sources, 100 messages a month, citations included.
Answers that stay inside your sources
Set an agent to “My Data Only” and it answers strictly from the content you gave it, cites the source for every claim, and politely declines anything your sources don't cover — no drifting into general knowledge or unrelated tasks.
CustomGPT alternative — common questions
Is there a free CustomGPT alternative?
Yes. AgentoGPT has a free plan that costs $0 forever — 1 agent, 5 sources per agent, 100 messages a month and citations included, with no credit card required. CustomGPT.ai has no free plan; it offers a 7-day free trial of its paid plans, and its FAQ states a credit card is required to start the trial.
How much does a CustomGPT alternative cost?
AgentoGPT's paid plans are Starter $19/mo, Pro $79/mo and Enterprise $299/mo, with lower per-month rates on yearly billing ($15, $63 and $239). For comparison, CustomGPT.ai's paid plans start at $99/mo for Standard and $499/mo for Premium, with custom pricing for Enterprise.
Can I migrate my content from CustomGPT.ai to AgentoGPT?
There is no one-click importer, so you re-add the same sources you used before: upload your files (PDF, DOCX, TXT, Markdown, HTML, CSV, JSON and XML), paste text, point at individual page URLs, or hand over a sitemap.xml and AgentoGPT crawls and indexes every page it lists. Most agents are rebuilt in a few minutes.
Will my AgentoGPT agent answer only from my content?
Yes, if that's what you want. Set the agent's Data Source Control to “My Data Only” and it answers only from your sources, shows a citation for each answer, and politely says it doesn't have that information yet when your sources don't cover the question. If you'd rather it also use general knowledge, that's a per-agent setting too.
Can I embed AgentoGPT on my website and use an API?
Yes. Paid plans include an embed widget that drops onto any site with a single script tag, every agent can be shared through a public link, the REST API uses scoped keys you control, and each agent can also expose its own MCP server endpoint for AI tools.
