What it is
ChatGPT is an AI assistant you use in a chat window, a mobile app, or through an API. You type or speak a request and it responds with text, images, data analysis or code.
It is the most widely used tool of its kind, which matters practically: every tutorial, integration and workflow guide assumes it, and most other software that has added AI features has built them on the same underlying models.
I have paid for it continuously for over two years alongside Claude, and I use them for different jobs.
What it does
The breadth is the point. In a normal week I use it for research framing, brainstorming, image generation for internal mockups, spreadsheet formulas, quick data analysis on a CSV, and turning rough notes into something structured.
Custom instructions and projects let you set context once so you stop re-explaining your business in every conversation. That is the feature most people never configure and the one that most improves the output.
Data analysis is genuinely strong. You can upload a spreadsheet and ask questions about it in plain English, and for a small business that removes a real skills barrier.
Where it is weakest is finished prose. It writes fluently and generically, and it drifts back to its own voice over a long piece however detailed your brief.

Pros and cons
Pricing
| PLAN | WHAT YOU GET | WORTH IT FOR |
|---|---|---|
| Free | Access to current models with tighter limits. | Deciding whether the output suits you. |
| Individual paid | Higher limits, image generation, data analysis, custom GPTs. | Most people. This is the tier that does real work. |
| Business or Team | Shared workspace, admin controls, data excluded from training. | Any business handling client information. |
| API | Pay per token for use in your own software. | Building it into a product or workflow. |
Prices and tier names change often. Check the pricing page, and use the free tier for a week before paying.
The individual paid tier if you work alone, or the Business tier the moment client data is involved, because that is the plan where your inputs are excluded from training. Do not pay for the API unless you are building something.
Alternatives
My verdict
ChatGPT is the safest single AI subscription for a small business, because breadth beats depth when you only have one. It is not the best writer of the group and it is the most capable all-rounder, and for most people that is the more useful property.
What changed my use of it was configuring custom instructions properly and building three custom GPTs for jobs I do weekly. Unconfigured, it is a clever chat window. Configured, it removes a few hours a week.
If you write for a living, pair it with Claude and use each for what it is good at. If you do not, this alone covers almost everything.
