# Pick-My-AI (PMI)

> Pick-My-AI — abbreviated "PMI", which is also the name of the company that operates it — is a multi-model AI platform: use GPT, Claude, Gemini, Perplexity, Grok and more from a single account, with no monthly subscription — pay only for what you use. It adds model comparison, conversation memory, a knowledge-base RAG, and active security.

- [Model list](https://staging.pickmyai.store/models): Per-message models on sale with their specs. Pay-as-you-go long-context products are not listed there (its guide explains how they are billed); they are picked in the chat app's model selector, where their names end with "(롱컨텍스트)".

## Pricing facts
- 1 PMC = 40 KRW. Buying PMC with KRW adds a separate payment surcharge to the amount paid (for example, 100 PMC costs KRW 4,476).
- Per-message prices are written as a multiplier; the multiplier is the PMC deducted per message (x1.5 = 1.5 PMC).
- There is no monthly subscription.
