I spent 6 months building features nobody asked for.
What finally got me out of that loop? Talking to customers every week.

Your reply

I wonder if talking to customers is actually the fix — or just talking to them earlier.

How often do you think you need to hear the same problem before it’s worth building for?

We shipped a feature last week that I was convinced people would use.

Almost nobody did.

Today I’m removing it. Building in public also means deleting in public.

How an audience grows

A reply is the beginning of the relationship.

People notice a useful reply, visit your profile, and read what else you have to say. Give them a reason to follow, keep showing up, and let trust develop over time.

01—03 A reason to discover you

  1. 01

    See a useful reply

    A relevant idea adds something to a conversation they already care about.

    Replies
  2. 02

    Visit your profile

    They look for the person, experience, and perspective behind the reply.

Build a body of original writing that gives new readers a reason to follow and familiar readers a reason to return.

Scheduled posts publish automatically. You can edit or reschedule.

03 / Voice

The more you write, the more Echo sounds like you.

See how Echo writes in your own voice →

Set your voice once. Then keep writing and editing normally — Echo learns from your changes and gets closer to how you actually write.

  • Start with your voice. Writing samples, topics, style controls, and your own guidance shape the first drafts.
  • Every edit teaches Echo. Change a generated reply or post, or write one from scratch — future drafts adapt.
  • You stay in control. Echo learns your style, not your opinions. The ideas, judgment, and final word stay yours.

Writing guidance

Be specific. Write like a founder sharing what they learned. Skip the hype.

How an edit can shape later writing

“Here’s what I learned from shipping too early.”

“Shipped this too early. Took me about a day to realize it.”

Every edit teaches Echo. The next draft sounds more like you.

Getting started

Set up once. Start growing.

Connect X, teach Echo how you write, choose who you want to engage with, and set your posting schedule.

    Connect X

    Authorize your X account so Echo can learn from your writing and publish scheduled posts.

    Build your Voice

    Choose your topics and shape how Echo should sound. Your existing posts give it a starting point.

    Choose reply authors

    Pick the people whose conversations you want to join. Echo checks their latest posts every day for reply opportunities.

  4. 04

    Set your posting schedule

FAQ

A few things worth knowing.

Which platforms does Echo support?

Echo currently supports X.

Does Echo publish replies automatically?

No. You review and edit a reply, then choose Reply in X to open a prefilled composer. You complete publication in X. A reply handoff in Echo is not confirmation that the reply was published.

Can Echo publish posts automatically?

Yes. Schedule a reviewed post for your next recurring slot or a specific date and time, and Echo publishes it through your connected X account. You can also publish immediately, reschedule posts, or pause autoposting.

How does Echo learn my voice?

Echo uses recent original posts, your topics, writing guidance, and four style controls. Your edits to generated posts and replies inform later drafts. Your current settings remain in control, and you review the final writing.

What if I do not have enough posts?

You can paste representative writing samples or retry the analysis when you have more posts. You don’t need an established audience or a minimum follower count.

Can I use more than one account?

Yes. Scale lets you connect up to three X accounts. Starter and Growth support one. Each account has its own Voice, settings, and content, while all connected accounts share the plan’s monthly usage allowance.

What does monthly usage mean?

Your plan includes a monthly allowance shared across discovery, generation, and publishing. Echo shows how much remains as a percentage. Editing drafts and opening a reply in X do not use the allowance. It renews after each successful monthly payment, and unused usage does not carry over.

Can I include links?

Echo currently supports link-free posts and replies. Keep product links in your X profile or other places you manage outside Echo.

Will Echo guarantee followers or sales?

No. Echo helps you publish useful ideas consistently, but growth still depends on what you say, who it reaches, and how people respond. Reach, trust, followers, and sales are never guaranteed.
