ChatGPT vs Claude vs Grok for answering customer messages
Any of the big AI assistants can answer your customers once it has access to your chats. The differences that matter for a business are mostly practical: how you connect it, which plan you need, and which one your team already uses. Here is how each connects to Spaces, with the steps checked against each company's own documentation.
How each one connects
| Assistant | Where you add Spaces | Sign-in |
|---|---|---|
| Claude | Customize, then Connectors, then Add custom connector | Sign in to Spaces in the browser |
| ChatGPT | Settings, then Apps & Connectors, with Developer mode on | Sign in to Spaces in the browser |
| Grok | grok.com/connectors, then New Connector, then Custom | Sign in to Spaces in the browser |
What is the same whichever you pick
- The same Spaces account, channels and limits.
- The same tools: reading chats, replying, sending files, scheduling and more.
- The same safety rules: limits, pacing, warm-up and no blasts.
- You can switch assistants later without reconnecting your WhatsApp or Instagram.
How to choose
- Use the assistant your team already pays for and is comfortable with.
- Check that your plan allows custom connectors. Menu names and plan rules change, and each company's help pages have the current details.
- Try it on real questions from your customers, and pick the one whose answers you would be happy to send.
