The Exact AI Connect connector works with both ChatGPT and Claude. That raises a logical question: which one should you choose? The answer depends on what you want to do with it and how much you are willing to pay.
We use both tools every day and we see where they excel and where they fall short. This is not a marketing story but an honest overview based on our experience.

The connector requires MCP support, and that is only available in paid subscriptions. The prices are comparable at the moment.
Please note: on top of the AI subscription you pay for the Exact AI Connect subscription (Essentials or Analytics). So the total cost is the AI tool plus our connector.
This is where the biggest difference lies. Accounting questions are about exact numbers, the right tables and correct calculations. No room for interpretation.
Claude is generally stronger at:
- Logical reasoning for complex questions (multiple steps, comparisons)
- Consistently using the right tables and fields
- Clearly indicating when data is incomplete
- Fewer "hallucinations" with financial calculations
ChatGPT is generally stronger at:
- Speed with simple lookup questions
- Versatility (text, images, code in one conversation)
- Familiarity: many users already know the interface
- Broader integration options beyond accounting
MCP (the technology behind the connector) works in both tools, but the implementation differs.
Claude:
- MCP is an Anthropic standard; Claude implements it natively
- The connection is usually more stable
- The tool is automatically available in every conversation (no manual activation)
ChatGPT:
- MCP support is newer
- The tool has to be activated manually for each chat
- Occasional connection issues, especially during longer sessions
In practice both tools work well. With Claude the experience is a little smoother, with ChatGPT it sometimes takes an extra step.
| Situation |
Recommendation |
Why |
| You already use ChatGPT every day |
ChatGPT |
Low threshold, no new tool to learn |
| You do complex financial analyses |
Claude |
Better reasoning logic, fewer errors |
| You want the connector to be as simple as possible |
Claude |
No manual tool activation needed |
| Your team already works with ChatGPT Team |
ChatGPT |
Consistency in tooling |
| You want the lowest risk of hallucinations |
Claude |
Stronger in factual accuracy |
| You combine accounting with other tasks |
ChatGPT |
More versatile beyond financial questions |
If you use the connector mainly for your accounting and you have no preference, we recommend Claude. The reasoning logic is stronger for financial questions and the MCP integration is more stable.
Do you already use ChatGPT every day for other tasks? Then the connector works well there too. Most questions produce the same result, regardless of the tool.
And the best part: you can switch. The Exact AI Connect connector works with both tools at the same time. You can use Claude for analyses and ChatGPT for quick lookup questions, with the same subscription.
During the free trial period you can test the connector with both tools. Ask ChatGPT and Claude the same question and compare the answers. That way you can find out for yourself which tool suits your way of working best.
