Plans

Two plans. Half the price comes back as test credit.

Pay by the month and cancel when you like. Each paid month adds half its price to your account as credit for running tests. Prices are in US dollars and exclude tax.

Basic

$49 a month

Includes $24.50 of test credit each month

The Prompt test, for working on a prompt yourself.

  • Test cases and checks drafted from your prompt
  • Models side by side on the same cases
  • Cost shown next to quality
  • A rewrite of your prompt from what failed
  • Your own examples, imported
  • Results you can share with a link
  • A coding agent connected over MCP, for use while you work

Pro

$200 a month

Includes $100 of test credit each month

Everything in Basic, plus the heavier work and tests that run without you.

  • Evolve it: a longer search that tries many versions of a prompt, for when one rewrite is not enough
  • The API, for starting tests and reading which model each one points to from your own servers
  • Pull-request checks, so a prompt or model change is tested before it merges
  • Scheduled rechecks, which rerun a saved test when a model or a price changes and once a week, within a spending limit

How credit works

When a month is paid, half its price is added to your account as test credit: $24.50 on Basic and $100 on Pro.

Running a test spends credit. Each model call costs what the lab charges for it, plus 20%. You see an estimate before a test runs and pay what it really cost.

Credit that comes with a plan does not expire while the plan is active. If you need more in a month, you can add credit on top, from $10.

The free trial

A new account starts with $10 of test credit for 7 days. The trial includes every feature, the Pro ones too. No credit card needed.

When the trial ends, running more tests needs a plan. Your results stay there to read, with or without one.

Questions

What happens when my credit runs out?

Tests stop until there is more. You can add credit from $10 at any time while you have a plan, or wait for next month's credit. We never take an extra payment unless you ask for one.

Can I cancel?

Yes, at any time, from the credit page in your account. No further payment is taken, and you keep the plan until the end of the month you have paid for. Credit you have left still works after that, until it is spent.

Can I change plan?

Yes, from the same page. The features of the new plan start straight away. The monthly credit of the new plan starts with your next paid month.

Is tax included?

No. Prices are in US dollars and exclude tax. VAT is added at checkout where it applies. This will show on your card statement as INCREMENTO.

Do I need a plan to read my old results?

No. Reading results never needs a plan.

I already bought credit. Does it still work?

Yes. Credit you have paid for keeps working until it is spent, with or without a plan.
