Building was the fun part. Nobody is reading your changelog. Kōlea writes the launch email in your voice, sends the sequence, and shows you which message made the sale on your Stripe.

If you'd rather not leave the terminal, your AI can run all of it over MCP.

See how it works

One bill

It does the job of four apps, and tells you what to send next

Kit sends your email, Ghost publishes it, Shopify sells your stuff, and testimonial.to collects the kind words. None of them know the others exist, and none of them tell you what to do next. Kōlea does all four on one list, and it comes with a plan.

  • Kit or Mailchimp Newsletter and sequences Broadcasts, a welcome series, launches, and after-sale follow-ups that stop the moment someone buys.
  • Ghost, WordPress, or a CMS Your site Every email can go up as a post on your own domain. Bring your Ghost theme if you have one.
  • Shopify or Gumroad Shop on your Stripe Downloads and memberships through your own Stripe account. Kōlea takes nothing from a sale.
  • testimonial.to Wall of love Asked for a week after the sale, each letter with proof of who wrote it and what they bought.

What the four apps don't have

  • Intelligence An editor's read of your own story that finds the parts worth telling. A Ghostwriter that writes in your voice and leaves your stories for you to tell. A council of readers who review the draft before you send.
  • Strategy Twelve sequence starters that each explain why they work. Three launch plays and five sales page frameworks. A plan for what to send next, and the reason behind it.
  • Care Readers can leave one thing and keep the rest. The AI can't send. Opens never count. Every dollar of your sales stays yours.
  • Numbers It's one list, so the numbers connect. Which email made each sale, in dollars. What each post earned next to how many people read it. Whether the letters help, tested with a holdout. Who left what, and why.
Your terms An MCP server with 132 tools, so your own AI runs all of it: Claude, ChatGPT, Cursor, or something you built. It can't send until you switch that on, and every call is written down, the refused ones too.

Kit knows what you sent. Shopify knows what you sold. Neither knows the other exists. One list does.

01 Write

Help writing it, when you want it

Every week there's a newsletter to send, and some weeks there's nothing in your head. Kōlea gives you a first draft to argue with, a meter that catches prose that sounds like a machine wrote it, and a council of readers who review it before you send.

The Ghostwriter

Say it your way, every time

  1. 1 A topic and your take One line for the topic, then whatever you think about it: a story, a link, what the reader should walk away with.
  2. 2 Your voice, tuned once Six writers' styles on sliders and up to six voices of your own. Paste something you wrote and Kōlea describes how you sound.
  3. 3 A draft in your editor About a minute later, with three subject lines and a slop score. One undo brings back what you had.

What comes back. The note in double brackets is where Mara's own story goes.

A ghostwriter with rules

A ghostwritten email is the easiest place for machine prose to slip out under your name. So the Ghostwriter is held to the same rules as the slop meter, and to a few of its own.

Voices on the sliders

  • Direct storyteller
  • Bare bones
  • Wry and humane
  • Cool observer
  • Curious explainer
  • Plain reasoner
  • + up to six of your own

  • No invented facts

    Every number, name, quote and result has to come from your notes. If it isn't there, it isn't in the draft.

  • Your stories stay yours

    Where a moment from your life belongs, it leaves a note in [[ double brackets ]] saying what goes there.

  • Checked for slop

    Scored on the way back. If it isn't clean, it revises once with the meter's findings and you get the better draft.

  • Nothing saved, nothing sent

    The draft lands in the editor unsaved. You read it, change it, and send it yourself, or don't.

The slop meter

A slop meter with no AI in it

Readers can tell when a model wrote something, usually by the second sentence, and that's where they stop reading. So I wrote down the habits that give it away.

The slop meter scores every draft from 0 to 100 as you type, yours or the Ghostwriter's, underlines what it finds, and tells you why each one reads badly. It runs in your browser. Your draft isn't sent anywhere to be scored, and no model is asked what it thinks.

  • Here's the thing:

    "Here's the thing" An announcement that a sentence is coming. Delete it and say the sentence.

  • It's not about syntax, it's about thinking in processes.

    "It's not X, it's Y" Knocking down a claim nobody made, to make the real one sound deeper. Say Y once.

  • Faster. Cleaner. Smarter.

    Staccato run Fragments lined up for a drumbeat. Join them into one sentence that says something.

  • Let that sink in.

    Mic drop A line telling the reader how to feel about the last line. Trust the last line.

  • In today's fast-paced landscape

    Grand opening Opening from orbit. Start with the specific thing that happened to you this week.

  • Those notes are the ones Kōlea shows you, word for word. Quotes and code are left alone. More about the slop meter

The reader council

A rigorous review from a council of readers, before you send

Tell Kōlea who reads you with four choices: what they do, how much they know, why they read, and how patiently. Then ask for a review.

A fan, a skeptic, and someone in between each read the draft on your screen and say what they think. An editor reads it last and tells you what to keep and what to cut.

Then fix it, right there. Every note has a Fix it button, and Claude makes the change in a copy of your draft, marked up like tracked changes in Word. Accept it, reject it, or dismiss the note and move on. Your draft stays exactly as it was until you say so.

Your readers

  • Software developers
  • Doing it every day
  • To learn how
  • Skims on a phone

The fan

The bakery is the bit I'll remember. I built a to-do app first too and never finished it.

The skeptic

Fine, boring first. But some people learn by building the fun thing. Say who this advice is for.

In between

I'd like one line on what a context is before the paragraph that leans on it.

The editor

Fill in the morning your sister texted you. That's the whole email. Keep the chat room as the setup, and cut the second half of the last paragraph.

An example review of the draft above, so you can see the shape of it.

Act on every note, without leaving the page

The review opens next to your draft, like comments in a shared doc. Click a highlighted line and its note lights up. Claude's fixes show up in place, crossed out and underlined, so you can see exactly what changed before you keep it.

The review desk: a draft with Claude's suggested changes marked up on the left, and the editor's verdict, three readers, and notes with Fix it and Dismiss buttons on the right

  • Fix it

    Claude makes the smallest change that answers the note. Where only you know the story, it leaves a [[ placeholder ]] for you.

  • Dismiss

    Read the note, decide it's wrong, and move on. Dismissed notes wait under Done in case you change your mind.

  • Fix everything

    One click sends every open note to Claude. You still accept or reject each change on its own.

  • Review again

    The readers read the copy with Claude's changes in it, so you find out if the fixes landed.

Nothing in your draft changes until you click Accept all and save. More about the reader council

Kōlea's AI, included

Every plan comes with a monthly AI allowance and nothing to set up. You see what each call cost, and it stops at the limit instead of surprising you.

Or bring your own key

Paste an OpenRouter key and pay OpenRouter directly, with no limit from us. Either way the writing is done by Claude, and your prompts and its answers aren't kept.

Why Kōlea

Why not Ghost, Kit, or Drip?

They're all good at what they were built for. But most people end up paying for two or three of them, plus a testimonial widget and an AI writing tool, none of them talk to each other, and none of them tell you what to send next. Kōlea is one place with a plan in it, built for people who write and sell what they make.

Only in Kōlea

  • A first draft in your voice From a topic and your take, with your own stories left for you to tell.
  • A slop meter with no AI in it 34 rules that catch machine-sounding prose, scored in your browser as you type.
  • A council of readers before you send A fan, a skeptic, someone in between, and an editor. Claude fixes what they find, and you accept or reject each change.
  • Dollars next to every email Each sale traced to the email the buyer clicked. Opens never count.
  • Leave one thing, keep the rest Readers can drop a launch and keep your newsletter, checked right before every send.
  • A wall of love with receipts Testimonials that show what the writer bought, and a test of whether they sell.

Your site runs Ghost themes, your sales go through your own Stripe, and Kōlea takes nothing from them.

02 Set up

It remembers who you are and what you do, and helps you get where you want to go

Nine steps, one question at a time, and each one comes with an answer already filled in from what you've told it so far. Stop whenever you like. It keeps your place.

  4. 4 Your list Bring it from Kit, Ghost, Mailchimp, Drip, beehiiv, or a CSV, or start fresh with a signup form.

About the AI bit: setup tells you what the writing helpers do before any of them run, then asks whose AI to use: the allowance on your plan, or your own OpenRouter key. Nothing you do in setup sends a single email.

03 Sell

From an idea for an offer to a happy customer

Launch Studio walks you through it in seven steps on one screen. Every step reads from the brief you write in the first one, so you only have to explain your offer once.

Launch Studio: seven steps down the left, and three launch plays to choose from, with The Big Sale picked and its plan laid out day by day

Three plays

  • Product Launch Formula Teach first, then open the cart for a few days.
  • The Big Sale Announce it, remind people, last call.
  • Evergreen funnel A free thing first, the offer a week later.

Three ways to write the sales page

  • Hook, Story, Offer
  • Person, Problem, Plan
  • Problem, Agitate, Solve

AI can draft an outline from your brief if you want one. The words on the page are yours.

Before the sale, and after it

The emails that lead up to a sale and the ones that follow it are wired together, so nobody gets pitched a thing they already own.

Testimonials

A wall of love, built in

You've probably seen the testimonial tools: a page full of hearts, a widget for your site, and another monthly bill. Kōlea has one built in. And because it knows your readers, every letter on your wall comes with proof of who wrote it.

I'd bought three Elixir courses before this one and quit every one of them by week two. I finished this one. The job queue chapter alone paid for it.

Said on Bluesky · 12 Sep 2026

Example letters, so you can see the receipts. Kind words people said somewhere else can go up too, with where and when they said them.

Three ways to ask

The hard part of testimonials is asking at the right moment without making people fill in a form. Kōlea already knows who they are, so they only have to write.

  1. A week after they buy

    Launch Studio's last step is one short note, a week after the sale. Is it working for you? If it is, here's a link to say so. Put the same link in any after-sale sequence you write.

    And if you're enjoying it, would you tell other people? Tell me how it went

  2. A link in any email

    Type {{testimonial_link}} into a broadcast or a sequence mail. Every reader gets their own link. There's no name or address to fill in, because Kōlea already knows who's writing.

  3. A link you can share anywhere

    One public page for your whole account, or one per offer. Put it in a video description or a social post. A letter counts once the writer confirms their email, and it's marked a verified buyer only if that address actually paid.

Put it anywhere

  • A wall at /testimonials on your own site
  • One script tag shows it on any other site
  • Drop letters into an email or a post from the editor
  • On an offer's sales page, where buyers decide
  • Star ratings marked up so search engines can read them

Nothing goes up unless the writer ticks the box saying it's OK, and they can take it back from their preferences page whenever they like. You approve, feature, and order the rest.

Do the letters sell? Kōlea checks.

A share of the people who visit an offer's page don't see the letters. Kōlea compares the two groups and tells you whether the letters help, hurt, or it's too close to call. It won't say anything until each side has 100 visitors and there are 10 sales between them.

04 Know

Know which email made the money

Most email tools stop at opens and clicks, and your shop, your site, and your testimonials each keep their own numbers somewhere else. Kōlea runs all of it on one list, so the numbers connect. Which email made each sale, in dollars. What each post earned, next to how many people read it. Which sequence is sending and which one has people sitting idle. Who left what, and why. Every percentage shows the two numbers behind it, and everything that happens on your account is written down where you can search it.

What you usually get

Open rate
61%
Click rate
4.8%

Apple opens mail on its own, so that first number is mostly a robot being polite. Kōlea never counts an open toward anything.

What Kōlea tells you

"The Elixir course is open" earned $2,086 from 14 sales.

Every one of those buyers clicked that email within 7 days of paying.

How the credit works

I got tired of tools that estimate. These are the rules, and you can check every one.

Join the waitlist Sales attribution

  1. The last click wins

    Inside a window you set: 7 days for a broadcast, 30 for a sequence or a form. A campaign named on the sale outranks the click.

  2. Opens never count

    Apple Mail opens everything it receives. An open tells you about a mail server, not a person.

  3. Credit is fixed when the money lands

    Change your windows next month and last month's sales stay where they were.

  4. Goals you can watch move

    Set one for a month, a quarter, or a year, and see which mail moved it. Every percentage shows the two numbers behind it.

Everything that happens is written down

I've spent too many hours asking a tool what happened and getting a shrug. If something happened on your account, it's a row, and you can read it, search it, or ask your AI to.

  1. An event log you can search

    Everything that happened on your account, in plain words, kept 90 days. On the Logs page and over MCP.

  2. Every message, and why

    Every email Kōlea meant to send is a row: sent, bounced, or held, and the reason if it was suppressed.

  3. Each reader's timeline

    What a person signed up for, clicked, bought, and left, in order, on one page.

  4. Every API and MCP call

    Logged with its arguments, its outcome, and how long it took. The refused ones too.

  5. Webhooks and Stripe

    Every delivery attempt to your app, and every Stripe event, whether it was applied or ignored.

  6. The send, as it happens

    Watch a broadcast go out: delivered, bounced, clicked, live on the broadcast page.
