What people ask us.

Which Calenzy plans include it?

Every plan, at no extra cost, including the free trial.

Which ChatGPT or Claude plan do I need?

Claude: every plan, including Free, which allows one custom connector. ChatGPT: today a Business, Enterprise or Edu workspace, on the web, until Calenzy is in ChatGPT's directory. Grok: every plan.

Can it publish my site or send a campaign on its own?

No. It prepares the change, you see it on your draft or in a test email, and publishing or sending stays a click in your dashboard.

What can it not do?

It cannot buy anything, take a payment, publish your site, send a campaign, change your team's access or see a password. Those stay in your dashboard.

Where does my clients' data go?

Only what you ask about goes to your chat app, under your own account with OpenAI or Anthropic and their terms. We send nothing else, and we never use your data to train AI.

Can my team use it?

Yes. Each person connects with their own Calenzy login and gets their own access. The owner can disconnect any of them from Settings.

Which languages does it understand?

Ask in your own language. Your chat app answers in it.
