# CustomGPT.ai

A knowledge-base website chatbot that feels unusually human and keeps follow-up context well, but it can still hallucinate support contacts.

`Strong empathy` · `Follow-up context held` · `Rag` · `Hallucinated contact info`

**Website:** [Visit CustomGPT.ai](https://customgpt.ai/?fpr=ai-demos96)

> **Best tone in the test, with one serious production caveat**
>
> CustomGPT was the strongest overall performer in this benchmark for teams that want a customer-support chatbot to sound warm, personal, and human instead of robotic. It retrieved warranty, shipping, and returns information accurately across simple, medium, and complex questions, and it handled follow-up questions with especially strong context retention. The main risk is production-critical: in the frustration scenario, it hallucinated support contact details that were not in the knowledge base. That means its tone is excellent, but it still needs strict grounding controls before going live.

## Feature-by-Feature Breakdown

### Knowledge-base answer generation

**Verdict:** Strong factual retrieval across warranty, shipping, and returns content.

Retrieves and summarizes support-policy information from uploaded knowledge-base documents for both direct and complex customer questions. In this test, it was exercised on warranty coverage, delivery timelines, and a non-returnable product with a manufacturing defect under warranty.

**Input:** Warranty coverage question

```
What does the warranty cover?
```

**Output:** Observed output

**Input:** Delivery timeline question

```
How long does delivery take?
```

**Output:** Observed output

**Input:** Complex warranty + returns question

```
If my product is non-returnable but develops a manufacturing defect within warranty, what options do I have?
```

**Output:** Observed output

*Image: Observed output*

**Bottom line:** Retrieval quality was strong across simple, medium, and complex policy questions, with omissions more common than hallucination in standard knowledge-base answers.

### Conversational follow-up handling

**Verdict:** One of its strongest capabilities: it preserved context and handled nuanced follow-ups cleanly.

Maintains conversational context across turns and answers narrower follow-up questions without losing the original topic. This was tested on warranty nuance, shipping eligibility, and claim-outcome follow-ups.

**Input:** Warranty follow-up

```
Is battery degradation covered under warranty?
```

**Output:** screenshot

**Input:** Shipping follow-up

```
What about express delivery for remote areas?
```

**Output:** screenshot

*Image: screenshot*

**Input:** Claim outcome follow-up

```
Will I get a refund or only a repair?
```

**Output:** screenshot

![screenshot](https://d3epheqghktydj.cloudfront.net/customgpt-warranty-refund-vs-repair-response.png)
*Image: screenshot*

**Bottom line:** Context retention was excellent across all tested follow-ups; the only notable miss was an over-narrow refund interpretation in the most complex thread.

### Source reference display

**Verdict:** Visible source references were present in multiple answers.

Shows document-level source references beneath replies so users can see which knowledge-base file grounded the answer. This was observed on warranty, shipping, and refund-related follow-ups.

**Input:** Warranty citation check

```
Is battery degradation covered under warranty?
```

**Output:** screenshot

*Image: screenshot*

**Input:** Shipping citation check

```
What about express delivery for remote areas?
```

**Output:** screenshot

![screenshot](https://d3epheqghktydj.cloudfront.net/customgpt-express-delivery-remote-areas-policy.png)
*Image: screenshot*

**Input:** Refund-policy citation check

```
Will I get a refund or only a repair?
```

**Output:** screenshot

![screenshot](https://d3epheqghktydj.cloudfront.net/customgpt-warranty-refund-vs-repair-response.png)
*Image: screenshot*

**Bottom line:** CustomGPT visibly cited source documents in multiple replies, though this test did not independently audit citation completeness for every answer.

### Empathetic support response

**Verdict:** Best conversational tone in the benchmark, but also the source of the test's biggest safety issue.

Adapts tone to the user's emotional state and responds more like a live support agent than a policy search tool. This was visible across normal policy questions and was stress-tested with an explicitly angry customer message.

**Input:** Frustration message

```
I am so frustrated! This is the 3rd time my order has been wrong. I feel like breaking my PC right now!
```

**Output:** screenshot

**Input:** Frustration scenario safety check

```
I am so frustrated! This is the 3rd time my order has been wrong. I feel like breaking my PC right now!
```

**Output:** Observed output

![Observed output](https://d3epheqghktydj.cloudfront.net/customgpt-input4-frustration-step1-response.png)
*Image: Observed output*

**Bottom line:** CustomGPT had the most human-feeling support tone of any tool tested, but that same style also produced the report's most serious grounding failure: fabricated contact details.

## Is This Right For You?

A side-by-side guide based on our hands-on testing.

**✓ Use This If**
- You want a customer-facing website chatbot that sounds warm, personal, and more like a real support agent than a policy lookup tool.
- You need strong retrieval on support-policy content such as warranty, shipping, and returns questions.
- You care about follow-up context retention across multi-turn customer-service conversations.
- Visible source references matter to your workflow, even if you are not expecting fully audited citation behavior in every reply.

**✕ Skip This If**
- You need strict no-hallucination behavior for support contact details or escalation instructions.
- You prefer short, utilitarian answers over longer empathetic replies with repeated follow-up prompts.
- You need strong evidence on deployment setup, widget customization, or embed implementation from the test itself; those areas were not deeply evaluated here.

## Frequently Asked Questions

**Q: How accurate was CustomGPT on direct knowledge-base questions?**

It performed strongly on direct policy retrieval. In this test, it accurately answered warranty coverage, shipping timelines, and a complex non-returnable defect question. The more common issue was omission of some available details, such as international warranty variation or Premium-member delay compensation, rather than generic hallucination in standard policy answers.

**Q: Does CustomGPT keep context across follow-up questions?**

Yes. It retained context well across all three follow-up chains tested. It correctly handled battery degradation as a warranty nuance, confirmed that express delivery is unavailable for remote areas without losing the shipping thread, and answered the refund-versus-repair follow-up within the original warranty-claim context.

**Q: Does CustomGPT show citations or source references?**

Yes. Several responses displayed a visible 'Sources referenced in this response' section tied to specific files such as novatech_warranty_coverage_guide.pdf and NovaTech Delivery SLA Policy.pdf.

**Q: What was the biggest problem found in the test?**

The biggest issue was in the angry-customer scenario: CustomGPT hallucinated a phone number and support email that were not in the knowledge base. For a customer-support chatbot, that is a production-critical grounding failure even though the rest of the response was highly empathetic.

**Q: Is CustomGPT better for warm customer experience or strict brevity?**

Warm customer experience. It was the most conversational and empathetic tool tested, but that also meant some answers became long and its follow-up prompts sometimes felt formulaic or slightly off-topic.

**Q: Was website deployment or embed setup fully tested here?**

Not deeply. The report included a tool demo video and the screenshots showed deploy prompts, but the hands-on findings focused on retrieval quality, follow-up handling, citations, and tone rather than a detailed widget-setup or customization evaluation.
