echo

email that sounds like you

echo is an AI assistant for the part of work that quietly eats your day: email. Connect a gmail account and it studies how you actually write — your tone, your go-to phrasings, your sign-offs — and builds a private style profile from your own sent mail. Then, for every email that needs a reply, it drafts one or two options that sound like you wrote them, drawing on the thread and a personal knowledge base you control.

It's built for founders, freelancers, and anyone managing high-volume email. echo only ever drafts — every reply opens in an editor to review, edit, and approve, and it sends through your own gmail only when you press send. A one-tap good-draft / needs-work signal sharpens it over time. The wedge is email; the goal is an assistant that learns your whole communication style.

how it works

  1. 01

    connect gmail

    Link one account; echo learns your voice from the last few months of mail.

  2. 02

    open an email

    For anything needing a reply, echo drafts 1–2 options in your style, using your knowledge base.

  3. 03

    review & send

    Edit anything, rate the draft, and send straight from gmail — nothing goes without your tap.

growth pricing question

PSPriya Shah2m ago

loved the demo — could you confirm what Growth includes vs Starter, and any flexibility on annual? we'd start with ~12 seats.

Hi Priya — happy to lay it out. Growth adds more seats, advanced attribution and priority support, and there's room on annual. Best, Alex

Hi Priya — so glad the demo landed. Happy to lay out Growth vs Starter, and we can set you up to trial on your own data first…

I take investor calls Tue–Thu afternoons (PT). Otherwise I prefer async over a meeting.
