The best ChatGPT alternatives for a business, by why you are looking

People look for a ChatGPT alternative for different reasons, and each reason points somewhere else. Some want the same kind of help from a different vendor. Some want the assistant already built into Google Workspace, Microsoft 365, Notion or Slack. And some have noticed that a chat window only helps while somebody is typing into it. This list is for a business, and it is sorted by which of those is yours.

The short answer

If ChatGPT does the right kind of job and you want it from somewhere else, pick the assistant that lives where your company already works: Gemini if you run on Google Workspace, Microsoft 365 Copilot if you run on Microsoft, Claude Tag if you standardize on Claude and live in Slack. If the reason is that the chat only helps while somebody drives it, that is a different purchase: agents you build, like Lindy, or an employee you hire and give a job, like Sanaf. For one person who wants a personal chatbot, the vendors’ own consumer apps are the place to start, and this list does not rank them.

Where we stand: We make one of the products on this list. Sanaf AI Solutions is ours and it is not at the top. If what you want is a better chat assistant for each person on your team, we say plainly that the entries above ours are the better buy, and plenty of businesses run one of them alongside us.

How this was put together: This is not a hands-on test. Nothing here was trialled, scored or benchmarked against ChatGPT. Each entry comes from our comparison page for that product, written from the vendor’s own live pages on the date shown against it, and each comparison links the pages it was read from so every claim can be checked. Only products with a comparison behind them are listed, so a chat app not yet covered is missing rather than judged. No competitor price is quoted; each comparison describes the pricing model and points at the vendor for the current figure.

Questions

Is there a ChatGPT alternative that costs nothing extra?
Some come with a plan you may already pay for: Gemini is included with most Google Workspace plans, according to the Google pages our comparison was written from. Sanaf starts free and charges for work done rather than per seat. Other vendors’ prices are not repeated here because they change, so check each vendor’s page for the current figure.
Why is ChatGPT not on its own list of alternatives?
Because it is the thing being replaced. Our comparison of Sanaf and ChatGPT sets out where ChatGPT is the better choice, and it links to this page, so the case for staying sits one click from the case for leaving.
Should a business replace ChatGPT or add to it?
Often add. A chat assistant for each person and an employee that holds a job answer different problems, and many businesses run both. Replace it when the tool you move to lives where your team already works and does the same job there.
What can an alternative do that a chat window cannot?
Keep working when nobody is asking. The chat assistants keep adding agent modes, so read each comparison for where the line falls today. The question to ask of any of them is whether the work carries on when nobody on your team is at the keyboard.
