When Should You Use AI? Here's How We Pick the Right Tool
AI is only as good as the job you give it, so here is how we match tool to task.
Which AI Should Your Business Actually Use?
Use Claude when you are writing something and ChatGPT for nearly everything else. That covers most of the decision, and the rest of this explains why, along with a few things worth knowing before you start.
Claude is the better writer
Claude sounds like a person wrote it. It holds a tone, it does not pad sentences with filler, and it takes direction well. Tell it to stop using a word or to match how you write, and it actually will.
That makes it useful for the writing most business owners put off. Replying to a difficult customer email, getting a first draft of a proposal out of your head and onto a page, turning rough notes into something readable. It gets you past the blank screen, which is usually the hard part.
The catch is that Claude cannot make images. If you need a picture, you are in the wrong place.
ChatGPT is the better all-rounder
Image generation is the obvious one, and it is genuinely good now. If you need a quick graphic for a social post or a rough visual to show someone what you are thinking, that is where we go.
It also handles data work, quick research, spreadsheet questions and voice conversations when you would rather talk than type. If you are not sure which tool fits a task, ChatGPT is the safer default.
Install the desktop apps
This is the tip we give most often, because almost nobody knows it.
Both ChatGPT and Claude have proper desktop apps for Mac and Windows, separate from the website. They are free, and they change how often you actually use the tools. Instead of opening a browser, finding the tab and logging in, you hit a keyboard shortcut and the window is there. That sounds minor. In practice it is the difference between using AI a few times a week and a few times an hour.
The desktop apps also work with files on your computer, so you can point one at a document and ask questions about it instead of copying and pasting.
A few things worth knowing
Give it more information than feels necessary. The most common mistake we see is a one-line request. Say who the audience is, what tone you want, how long it should be and what you do not want. A paragraph of instruction gets you something usable. Four words gets you something generic.
Tell it what to avoid. Naming the words and phrases you dislike is one of the fastest ways to make AI output stop sounding like AI output.
Check anything factual. Both tools will state something wrong with complete confidence. Names, dates, prices and anything about your own industry needs verifying before a customer sees it.
Never publish the first draft. Treat it as a starting point. The businesses getting real value out of AI are the ones using it to move faster on the boring parts, not to replace the thinking.
Keep your passwords out of it. We have seen people paste login details into a chat window without a second thought. Treat these tools like any other website you do not control.
Our Recommendation
If you can only justify one subscription, get ChatGPT. If writing takes up a real part of your week, pay for both. Either way, start on the free versions for a couple of weeks and see which one you actually open.
We use both every day across client work, so if you want a straight answer on where AI fits in your business and where it does not, talk to us.
