GMail AI Replier

What if AI could draft replies to all your emails, so all you have to do is skim through your drafts, make some changes, and click send? This is what this Google Sheet does for you, if you use Google Mail.

How it works

The Google Sheets script

1. fetches your emails using the built-in Gmail API
2. then uses the GPT-4 language model API to draft replies.
3. and saves the replies as drafts in your GMail account, so you can review them before sending them.
