How it works

The problem: email takes too long

The average professional spends 28% of their workday on email. Most of that time isn’t thinking — it’s typing. You already know what you want to say. The bottleneck is turning that into a well-written reply.

Chatbots like ChatGPT can help with writing, but they can’t see your inbox. You have to copy the thread, paste it in, explain the context, generate a reply, copy it back, and paste it into the compose box. That’s not saving time — it’s adding steps.

How dassi handles email

1. Open dassi on any email

Click the dassi icon in Chrome’s sidebar while viewing an email in Gmail, Outlook, or any webmail. dassi instantly reads the full thread — sender, subject, previous replies, everything visible on the page.

2. Tell it what to write

“Draft a polite decline.” “Say we can meet next Tuesday.” “Ask for the invoice and cc accounting.” Plain language instructions, no templates needed.

3. Review and send

dassi drafts the reply and places it in your compose box. Edit if you want, then send. You stay in control — dassi never sends anything without your approval.
