Built around your account

Your plan should know who you are.

Clerk secures identity. Stripe or the App Store handles payment. ChatUp’s backend remains the source of truth for verified access—so a browser return page never grants Pro by itself.

Identity

Sign in once

Clerk keeps account identity separate from billing credentials and AI content.

Billing

Choose where you pay

The Stripe template attaches the trusted Clerk identity; mobile purchases stay with Apple.

Entitlement

Verify before access

Every account view asks the server for fresh subscription state and fails closed if sync is unavailable.

Thoughtful by default

Know what leaves the conversation.

ChatUp’s policy explains what is stored, which AI provider receives a prompt, how subscriptions are handled, and how to delete your data.

Your next idea is waiting

Bring your whole AI world together.

A faster, calmer way to explore models, use creative tools, and keep access tied to you.
