Upgrade Your Prompt Index Plan

Collections allow you to organize your prompts into folders for better management. You can create separate collections for different projects, topics, or purposes. Free users get 1 collection, while paid plans get unlimited collections with additional features like private sharing.

All subscriptions are billed monthly. You can upgrade, downgrade, or cancel your subscription at any time from your account settings. If you cancel, you'll maintain access to your paid features until the end of your current billing period.

The AI Humanizer helps make AI-generated content sound more natural and human-like. The Prompt Optimizer helps improve your prompts for better results with AI systems. Free users get limited access, Basic subscribers get 20 uses of each tool monthly, while Pro users get unlimited access (subject to fair usage).

Yes! You can upgrade or downgrade your plan at any time. When upgrading, you'll get immediate access to your new features. When downgrading, you'll maintain access to your current features until the end of your billing period.

We accept all major credit cards including Visa, Mastercard, American Express, and Discover. All payments are securely processed through Stripe.

If you downgrade from a paid plan to the free plan, you'll be limited to one collection. We won't delete your additional collections, but you won't be able to access them until you upgrade again. The system will automatically keep your most recently used collection active.
