Comparison

AddSync AI vs using ChatGPT or Claude on your own

Your people probably use ChatGPT or Claude already. The question is what happens when the question is about their mailbox.

The short answer

AddSync AI does not replace ChatGPT or Claude. It sits between the AI and the mailbox so that IT sets the rules, people approve actions and every question is recorded.

What changes

The AI can be the same. The way it reaches the mailbox is different.

Vendor products change. The statements about other products are based on their public documentation in October 2026, so check the current terms before you decide.

The problem with "just use ChatGPT"

When people paste mail into a chat window, nobody sees it. There is no filter, no record and no way to answer an auditor. Banning it rarely works, because the tools are useful.

What AddSync adds

  • A guard that checks each request against your rules.
  • Data filters that hide what the AI should never read.
  • Approval for anything that changes something.
  • A journal without message text.

People keep using the AI tool they like. IT gets control.

Questions

Do I still need a ChatGPT or Claude plan?

If you use your own AI tool with AddSync, yes. You need a plan that supports connecting external tools. Alternatively, AddSync chat can be used. Ask us which suits you.

Does AddSync store my mail?

No. Mail stays where it is, and the journal does not keep message text.

Is my data used to train AI?

AddSync does not train AI models on your mailbox or calendar. Check the terms of your chosen AI provider as well.

Can AddSync block certain mail from the AI?

Yes. Data filters let IT hide folders, senders or items from the AI.

Try it on your own mailbox

A 14-day pilot with a few mailboxes shows more than any comparison.
