email that sounds
like you wrote it.

echo learns your voice from your own mail, then drafts replies you just review and send.

connect gmail, and echo studies how you actually write — tone, phrasing, sign-offs. open an email, get two drafts in your voice, edit, send. nothing leaves without your tap.

three steps to a quieter inbox

set up once, then just review and send

01

connect gmail

link one gmail account with google sign-in. echo reads the last few months of mail to learn how you write — read and send scopes only.

02

echo learns your voice

it builds a private style profile from your sent mail — tone, phrasing, sign-offs — and a knowledge base you can edit by hand.

03

review, then send

open an email that needs a reply and echo drafts 1–2 options in your voice. edit anything, then send straight from gmail.

style learning

drafts that sound like you

echo studies your own sent mail to learn your tone, your go-to phrases, your sign-offs — and reuses how you've answered similar emails before.

every draft is a starting point, not a send. you review and edit before anything leaves your inbox.

personal knowledge base

  • fact

personal knowledge base

facts it can reference

add the things echo can't infer — your availability, pricing, links, how you like to handle common asks. plain text, edited by hand.

echo pulls the relevant entries into each draft, so replies are accurate, not just on-tone.

private by design

your inbox stays yours

one gmail account, connected over google's official oauth with read and send scopes. nothing is posted on your behalf without your tap.

feedback is a single signal — good draft, or needs work — so echo gets sharper the more you use it.

questions, answered

how does echo learn my writing style?

when you connect gmail, echo reads your recent sent mail to build a private style profile — your tone, common phrasings, and sign-offs — plus a knowledge base you control. it never sends anything without you reviewing it first.

does echo send emails automatically?

no. echo only drafts. every reply opens in an editor for you to review, tweak, and approve. it sends through your connected gmail account only when you press send.

which email providers are supported?

the mvp supports a single gmail account, connected with google's official oauth. outlook and other providers, plus slack and messenger, are on the roadmap — email is the wedge.

is my email data private?

echo connects one account over oauth and only uses your mail to draft your replies and build your style profile. you can disconnect at any time, and you review every draft before it sends.

what does it cost?

echo is in early access as part of ogbuilds — built in public. the mvp is free to try while we learn with our first users.

get your evenings back.

connect gmail and let echo draft your replies in your own voice. you stay in control of every send — echo just gets you 90% of the way there.
