All AIs in one place — including ChatGPT

Pay per use — not per month

ChatGPT Plus costs $20/month whether you use 10 messages or 10,000. With OneAIPass, you pay only for the tokens you actually consume. Most casual users spend $2–8 per month. Heavy months cost more; light months cost less. Your bill matches your usage. See the math →
