Frequently asked questions

Questions fréquentes.

What is a Claude-optimized prompt?+

Claude (Anthropic) responds better to prompts that include an explicit role, ordered instructions, a defined output format, and clear constraints. PromptPro restructures your prompt according to these principles.

Are my prompts stored?+

Your optimizations are saved in your personal history. They are never shared or used to train models.

Which Claude models are targeted?+

Optimizations target Claude 3.x and 4.x (Haiku, Sonnet, Opus). The principles apply to the entire Claude family.

Can I use my credits on multiple devices?+

Yes. Your balance is linked to your account, accessible from any device.

Do credits expire?+

No. Your credits are valid indefinitely.
