Terms of use

What the service offers you, what is expected of you, and what happens if something goes wrong. Written to be read, not to put you off reading it.

About this translation

This is a translation provided for convenience. The Spanish version is the legally binding one; in the event of any discrepancy, the Spanish text prevails.

What this service is

Prampt rewrites the prompt you give it so a language model reads it better: it pins down what was vague, orders what you are asking for and flags what is missing. The rewriting is done by a language model, through the Anthropic API. The result may be longer than the original: what is optimized is the clarity of the instruction, not its size. It is a text tool, not an advisory service, and it makes no promises about the results a model will give you with the optimized prompt.

Your account

You need a valid email address and you are responsible for keeping your credentials and API keys confidential.

API keys are personal. They are shown once when created and only their hash is stored, so we cannot recover or look them up. If you suspect one has leaked, revoke it from the panel and create another.

Acceptable use

By using the service you agree not to:

  • Automate requests against the site's public endpoints outside the documented API.
  • Use the service to process unlawful content or to infringe third-party rights.
  • Resell access or share your keys with third parties.

Usage limits and anti-abuse protection

Each plan includes a number of AI optimizations per month — 5 on Free, 150 on Pro, 400 on Power and 1,000 on Team — enforced on the server and reset on the 1st of each calendar month. Deep rebuild mode counts as three. When the credits run out, AI optimization stops until the following month.

Each account allows three sessions open at once. Opening a fourth closes the oldest. It is a security measure and does not depend on your plan.

What does have a ceiling is the RATE, not the volume. The internal endpoint the site uses for the exact token count is limited by IP address, and the API is limited to 120 requests per minute per key. You can make as many optimizations as you want; what you cannot do is make them all at once.

The reason is that the exact count is computed by the model's tokenizer, and that capacity is shared across all customers. Without this limit, a single misconfigured integration would leave everyone else without service. If your legitimate use case needs a higher rate, write to us and we will adjust it.

Payments, renewal and withdrawal

Paid plans are taken out monthly or yearly through Stripe, which acts as the payment provider. Prices are shown excluding VAT, which is added according to your country at the time of charge.

The subscription renews automatically at the end of each period until you cancel it. You can cancel at any time from your account: you keep access until the end of the period you already paid for, and it is not renewed again.

If you subscribe as a consumer in the European Union you have fourteen calendar days to withdraw. As this is a digital service with immediate access, by subscribing you agree that performance begins straight away and you acknowledge that you lose the right of withdrawal once the service has been fully provided.

The price of a subscription already taken out is never raised. Any change in rates applies only to new sign-ups and is announced in advance.

Your content

The text you optimize is yours and stays yours. No rights over it are claimed and it is not used to train anything.

The result of the optimization is also yours, with no restrictions on use.

Warranties and liability

Every result comes with a word-by-word diff so you can check the change before using it. The decision to use the optimized prompt is yours.

The rewriting is done by a language model, so the same prompt may give different results on two runs. The engine is forbidden from inventing information and leaves bracketed gaps where the original did not say something, but there is no guarantee that intent is preserved in every case, especially in deep rebuild mode. Check the diff.

No liability is accepted for damage arising from service interruptions, from the loss of data held in your browser's local storage, or from the use you make of the optimized prompts.

Cancellation

You can delete your account at any time from Settings, with no process and no justification. Deletion is immediate and irreversible.

The service may suspend an account that breaches these terms, giving the reason unless doing so would compromise the security of the system.

Governing law

These terms are governed by Spanish law. If you are a consumer, you keep the rights granted to you by the rules of your country of residence and you may go to the courts of your domicile.
