AI for Gmail: Claude and ChatGPT with your rules
Your people ask Claude or ChatGPT about their Gmail and Google Calendar. You choose who may ask, what the AI may read and you see every question.
They sign in with their Google account. Nothing is copied to another place, and nothing is sent without a click.
Already using Gemini? What AddSync adds
Google Gemini works inside Google Workspace. AddSync AI gives you a second choice, and the same rules for every assistant.
Your choice of assistant
Your people use Claude or ChatGPT if they prefer it. You do not force one tool on the whole company.
One set of rules
The guard and the data filter work the same way for Gmail, Microsoft 365 and Exchange Server. You write the rules once.
A journal you own
You see who asked, when and which button. When an auditor asks, you open the journal.
How your people connect
No new mail app and no move of mail.
- 1You add the personYour administrator adds people one by one or from a list, up to the number of licenses.

Gmail next to Microsoft 365 and Exchange Server
Many companies run more than one mail system. Sales may use Gmail, the office Microsoft 365 and the finance team an Exchange Server. AddSync AI covers them with one guard and one journal, so you do not manage three tools.

Gmail questions
Do I need Gemini?
No. AddSync AI works without Gemini. You can use both, and the AddSync rules apply to the assistants that go through AddSync.
Is my mail copied out of Gmail?
No. The AI reads a message to answer a question and does not store it. The journal keeps who asked, when and which button, without the text.
Will my people need a new app?
No. They keep Gmail. They ask in Claude, ChatGPT or the AddSync chat, and drafts appear in their Gmail drafts.
Can I switch AI off for one person?
Yes. You switch AI off for one person, for a group or for everyone, at any time.
