The problem

Most AI email tools are copy-paste exercises

They can write a decent email, if you feed them every piece of context yourself. What if the AI could just go get the context on its own? What if it can truly be of assistance?

Capability & Features

An AI assistant with real access to your inbox

Search your emails

Ask "what did we quote this client in January?" and the assistant searches across all your connected email accounts.

Check your calendar

Need to suggest meeting times? The assistant reads your calendar, checks for conflicts, and proposes meeting times.

Draft replies in your team's voice

Set instructions for tone and style once, and every AI draft follows them across your whole team.

Find canned responses

The assistant searches your team's template library and uses the right one as a starting point for its draft.

Look up contacts

Ask about a contact and the assistant pulls their name, email, phone, and company from your contact book.

Customize with instructions & prompts

Set tone and style guidelines once, create reusable one-click actions, and they apply to every AI session across your team.

“The ability to put in MCP servers that I use, like Granola and Affinity, has made a pretty dramatic impact on my work. The quality of the AI responses feels like they've gotten a lot better, particularly the ability to look up calendar and bring in insights there.”

Go beyond email with MCP integrations

Ask the assistant to look up a customer's billing history in Stripe, create a Linear issue from a bug report email, or pull context from a Notion doc or your CRM/TMS, before replying. It all happens in the sidebar, in the same conversation.
