how it works

Three steps. Under a minute. No copywriter calls.

  1. 01

    Paste your source.

    An article, a transcript, a long essay. Anything past 200 words. Or paste a URL — we’ll fetch the body.

  2. 02

    Pick your formats.

    Tap seven, tap one. Each runs in parallel. Define your own format if the built-ins don’t fit.

  3. 03

    Ship in your voice.

    Train a voice profile with 5 past posts and the output stops sounding like a model — it sounds like you.

what you actually get

Output that doesn’t sound like AI.

Per-platform prompt engineering kills the AI tells. Voice profile training takes care of the rest. Below: an actual Twitter thread from a single short article. Unedited.

1/ I built a great product for two years and made roughly $0.

The fix wasn't a better product. It was 90 days of one short post per day, on the platform my buyers actually used.

By day 60, three companies had emailed me.
By day 90, I quit my job.

2/ Distribution is the moat.

In a market where anyone can build, the audience you patiently earn before you need them is the only durable advantage.

faq

Questions, answered.

Why do I need my own Anthropic key?+
Because it's the most honest model. You pay Anthropic directly at wholesale (about $0.01 per generation). No markup, no mandatory subscription, no surprise bills. We just provide the prompt engineering.
How much will my Anthropic bill be?+
Tiny. $0.005–$0.02 per run. A creator posting five sources a week spends $1–$3/month on Anthropic. New accounts get ~$5 of free credit to start.
Where is my API key stored?+
Only in your browser. It's sent with each generation request and used to call Anthropic on your behalf. We never persist it server-side and never log it. Clearing your browser clears it.
Does it sound like AI?+
We engineer prompts to mirror the source voice and ban the obvious AI tells (em-dash spam, generic openers, fake stats). Voice Profile takes 5 of your old posts and the output starts sounding like you, not a model.
What languages are supported?+
Any language Claude speaks well — English, Russian, Spanish, German, French, Portuguese, Polish, Ukrainian, Japanese, and more. Output language matches the source.
What if I clear my browser after upgrading to Pro?+
Pro is tied to your signed-in account, persisted in the database. Sign in on any device, your Pro window restores automatically.
Is my source content stored?+
No. It's processed in-memory and forgotten as soon as the response is sent. We don't train on your input. Voice profile and history live in your browser (or your account when signed in).
