Subject lines 1. 48-hour sale on our coffee subscription 2. A modest discount on coffee deliveries for two days 3. Coffee subscription sale ending soon Email (120 words) Hi there, Just letting you know about a 48-hour sale on our coffee subscription. It's a modest discount available for a couple of days if you want to start or change your plan. We roast coffee in small batches from beans we select carefully. Deliveries come as often as you like, which many find convenient for keeping a good supply at home. No rush, but the sale is only for 48 hours. You can find more on our site or just reply to this email with questions. We hope you find something you like. The beans are roasted to order so they arrive at their best. Let us know how we can assist. We appreciate your interest in our coffee.

How it works

  1. 1

    Write the brief

    Say what you need, for whom and how long. The same brief goes to every model.

  2. 2

    Read the drafts

    The drafts arrive side by side, each with its time and cost.

  3. 3

    Keep or refine

    Copy the one you want, or send a follow-up to every model at once.

Same brief, different drafts.

In the run above, all three models wrote three subject lines and an email. Claude Sonnet 5 also added a 20% discount and a Sunday end date that the brief did not give.

What it costs

A run on the 3 models above costs 7 credits, about $0.28 on the $20 bundle. Credits never expire, and your first 20 are free.

You pay for questions you ask. That is the whole model.

No plan, no seat, no monthly minimum, nothing to cancel. You buy credits once and they never expire, every model shows its cost before you run it, and we refund any run that does not finish.

Most model responses cost 1 to 5 credits · A very long prompt or answer costs 1 credit per $0.035 of model cost · The synthesis is priced separately

Priced before you run

Every model carries its credit cost in the picker and its real input and output price per million tokens on the panel, and the total for the lineup you have built sits under the Run button. We meter nothing after the fact.

Or bring your own key

Add an OpenRouter key in Settings and every model response runs on your own account and costs you no credits at all. Only the synthesis, which reads every answer and lists the claims, stays on ours.

Questions

Which models write?

Claude Sonnet 5, GPT-6 Sol and Grok 4.6 by default. You can swap them or add up to six models before a run.

Can I give the models my brand voice?

Yes. Add a system prompt in the workspace and every model gets it with each brief.

What kinds of copy work well?

Anything with several good answers: hooks, subject lines, emails, ad headlines, product descriptions, product names and rewrites for a new audience.

Try it on your own brief.

Write the brief once and compare what several models make of it.
