# Pro vs Free

Canonical page: `https://nanthai.tech/features/pro-vs-free`

Everything you get for free — and what Pro unlocks.

The free tier is a complete multi-model AI chat. Pro is a one-time $4.99 purchase that unlocks personas, memory, scheduled jobs, advanced search, integrations, and more.

## How it works

1. **Start free — no credit card needed** — Create an account and start chatting immediately. Multi-model chat, folders, themes, basic web search, and BYOK are all included at no cost.
2. **Use it as long as you like** — There's no trial period and no artificial limits on the free tier. You pay only for the AI tokens you use through your OpenRouter account.
3. **Upgrade once, own it forever** — When you're ready for personas, memory, scheduled tasks, integrations, and deep research, unlock Pro for a one-time $4.99 payment. No subscriptions.
