Final Verdict: Onyx Point AI vs CustomGPT.ai
Onyx Point AI suits an association that wants a vendor to build and run the whole thing. CustomGPT.ai suits one that wants to test on its own content now, see the price before a sales call, and show IT a security attestation.
When to choose CustomGPT.ai
- Your IT review needs SOC 2 and a written statement on how your content and members' questions are used.
- You want to start this month, not next quarter, with a 7-day free trial on your own documents.
- You want the assistant on your website, with API access for other tools.
When to choose Onyx Point AI
- You have no staff time for setup and want a vendor to run it.
- You want a product built exclusively for associations, including the Resell option for monetizing your content.
Migration & Switching Considerations
Before you sign with any vendor, ask for its security documentation and its data-use terms in writing. Include whether your content and members' questions are used to train models. CustomGPT.ai's 7-day free trial lets you load the same publications and compare answers and citations before you commit to an implementation project.
Pricing Comparison Summary
Onyx Point does not publish prices, so a side-by-side number is not possible until you book a demo. CustomGPT.ai starts at $99 a month, with Premium at $499 a month and a custom Enterprise plan. Ask every vendor what the first-year total includes, and compare it with the plan you would actually need. See customgpt.ai/pricing for full CustomGPT.ai prices.
Our Recommendation Process
- Pick 20 questions your members really ask. Include at least 10 that are answered only inside a journal, standard or handbook.
- Run them on both tools. Start a CustomGPT.ai trial with your own documents, and request a demo from the other vendor on the same content.
- Check the citations. For each answer, can the member see which document it came from?
- Ask both vendors for security documentation and data-use terms in writing. Ask for the attestation, and ask whether your content and members' questions are used to train models.
- Ask for the full cost. Get each vendor's first-year total, including setup, and compare them for the plan you need.
For most associations, the deciding check is step 3: whether members can see which document an answer came from.

Frequently Asked Questions
Is CustomGPT.ai a good alternative to Onyx Point AI?
Yes, for an association that wants to start on its own content and see prices up front. CustomGPT.ai starts at $99 a month, has a 7-day free trial and holds SOC 2 Type 2. GEMA’s member self-service on CustomGPT.ai handled 248,000+ queries at an 88% success rate. Onyx Point suits an association that wants a vendor to run everything, which takes a typical 8 to 12 weeks.
Do I need technical staff to set up CustomGPT.ai?
No. CustomGPT.ai’s website says no coding or technical expertise is required: you upload documents or enter your website and build the agent yourself. A 7-day free trial on Standard ($99 a month) lets you try it on your own publications.
What should an association test before choosing an AI assistant?
Write 20 questions your members really ask, with at least 10 answered only inside a journal, standard or handbook. Run them on each tool, check that each answer shows its source, and ask each vendor for security documentation and data-use terms in writing. CustomGPT.ai’s 7-day free trial lets you do this on your own documents before any commitment.
How long does Onyx Point AI take to launch, and what does it cost?
Onyx Point’s site says a typical implementation takes 8 to 12 weeks, with its team managing setup, integration, deployment and ongoing support. It does not publish prices, and its site invites you to book a demo. CustomGPT.ai starts at $99 a month, with a 7-day free trial.
Does Onyx Point use our content to train AI?
Its privacy policy (effective 12 November 2024) says it “may use Customer Content and Usage Data to train and refine our AI models.” Its homepage says “Your content stays yours.” Ask any vendor for its data-use terms in writing before you load your content. CustomGPT.ai’s security page says “No training or sharing your data.”
Can't we just use ChatGPT or Claude for our members' questions?
ChatGPT and Claude are general assistants. Building a member-facing assistant on top of them means designing and maintaining the document retrieval, the source links and the “I don’t know” behavior yourself. CustomGPT.ai provides those: by default, responses come only from your own content and link to their source. GEMA’s member self-service on CustomGPT.ai handled 248,000+ queries at an 88% success rate.
What would an association use this for?
A member asks “Which of our standards covers this process?” and the assistant answers from your standards library and links the source. At GEMA, member self-service on CustomGPT.ai saves more than 6,000 staff hours a year.
Is Onyx Point AI the same as Onyx (onyx.app)?
No. Onyx Point Systems makes an AI product for associations. Onyx at onyx.app, formerly Danswer, is a separate open-source enterprise search tool.
