Which AI tool is best?

I've been getting this question since years, in almost every training I run: which tool is the best?

So, tomorrow - to help you answer this - I will give you the specific workflow I give CFOs to decide which tool is best. Based on the tools you are using already.

Plus, you'll see 7 AI use cases and tricks my community of 3,551 members is using to become the go-to AI expert in Finance.

On top - you’ll get My 100 AI in Finance tips handbook delivered straight after registering.

November 2022

With AI there was a time where I could not sleep and I stayed in front of my computer (and my phone) all night.

It was November 2022 when I got access to ChatGPT - like the first day when it arrived - and I just kept trying everything because I thought, this thing... it cannot be that this exists. This is going to get taken away, or they are going to charge €10,000 for this!

But a lot has changed since then.

ChatGPT is not the only tool, and it’s really confusing on how you should be using all of them as there is a new release every month.

But think of it like this.

Imagine you need to drive from New York to Boston. In your driveway you've got a truck, a Ferrari, a Tesla, and an old beater. Which one gets you there fastest?

If you've never learned to drive, it doesn't matter which car you take. You're not arriving anywhere. If one of you is an experienced driver and the other just started, the experienced driver wins in any of the four cars. And if you're driving alone versus driving with a family of five, you need two different cars to do the same job well.

So to help you decide which car (or cars) you should be driving. I’ve put together this complete 90-page PDF comparison guide for you.

Inside, you'll find:

• The five questions you need to answer when deciding on a tool.
• The real context-window numbers (not the marketing ones).
• The permissions problem nobody warns you about.
• What a twelve-person finance team looks like, priced four ways.
• The three cost mistakes finance teams keep making (including the one buried in Microsoft's current Copilot discount).
• The split that actually predicts which tool wins at which tasks.

Read it, and the next time someone in your team asks "which AI should we buy?" you’ll be the one with the answer ;)
