Tell your inbox what to do.
Cortex Mail sits on top of Gmail and reads it for you. Type what you want in plain language — the app finds the thread, opens the right view, drafts the reply — and nothing goes out until you say so.
Opens the Today briefing
Every email gets a status before you open it.
As your inbox syncs, a model classifies each message from the sender's intent, not from a Gmail label. The Today view groups what needs a reply and what you're still waiting on, so the first screen answers “what do I deal with?” instead of listing 128 messages.
- Needs reply
- The sender is explicitly asking you for something.
- Waiting
- You’re waiting on them — a reminder or status check.
- Follow up
- A thread went quiet and probably needs a nudge.
- Important
- High-signal, no reply expected. Account and security notices.
- FYI
- Newsletters, receipts, notifications.
- Handled
- Already resolved. Nothing left to do.

Open a thread and the ask is already pulled out.
Each opened email gets a one-line reading: what they want, by when, and a reply drafted in your voice that lands in the compose window with one click. Below it, four one-click actions and a free-text box that already knows which email you're looking at — ask “what is she waiting on?” without pasting anything.
How a sentence becomes a click
- Your message goes to a ReAct agent on Groq (GPT-OSS 120B). Relevant emails are pulled from a Pinecone index first, so the model reasons over what matters, not your whole inbox.
- The agent picks from a small set of tools —
search_emails,get_email_body,reply_to_email,filter_emails— and every output is validated against a Zod schema before it's trusted. - Tool results become Redux actions. That's why “draft a reply” opens the actual compose drawer instead of printing text into a chat.
- Anything that leaves your account — sending mail — stops at a confirmation you can edit or cancel.
