Every plan has a monthly allowance. Pay once for 30 days and renew when you like. No card on file, no automatic charges.
AI-generated images use the same monthly and daily AI allowance as chat. Each plan has its own number of successful images per day across all chats (Free 2, Simple 10, Pro 20, Business 30, Vast 40, Developer 30; the Pro Trial 3 in total), resetting at midnight Bangladesh time. Uploading your own images does not use the generation quota.

One person can use all Duplibot API features on any paid plan, Simple, Pro, Business, Vast or Developer. No extra fee and no separate API plan is needed to get started: create a personal API key in your account and use it in Claude Code, Cline, Roo Code or any tool that speaks the Anthropic API.
Every chat shows the credits one reply used. A normal reply costs the credits below; long files, images and Research use more. All models draw from the same monthly credits, so the numbers show roughly how many replies a plan gives on each one.

Pro includes 2.2 times Simple's AI allowance. The reply estimates for Haiku, Sonnet and Opus are alternatives from one shared allowance, not separate model quotas. Long documents, big files, images, deep thinking and Research use more. Smaller models go further, and you see each model's cost before choosing it.
bKash, Nagad and Bangladeshi cards in taka, or PayPal, international cards and crypto in dollars, depending on what is switched on. Taka prices are fixed and do not move with the exchange rate.
Renew the same plan to add another 30 days and allowance on top. Switching plans starts the new one straight away. Your chats stay yours either way.
