In short: Duplibot is an AI chat workspace where you chat with Anthropic's Claude models (Haiku, Sonnet and Opus) in Bangla or English. It has a free plan, and paid plans that you pay for once, for 30 days, in taka (bKash, Nagad, Rocket, local cards) or in dollars. Nothing renews automatically. It is an independent product and is not made by or affiliated with Anthropic.
What can you do with Duplibot?
- Chat with Claude in Bangla or English, with your history saved.
- Write documents and export them to Word or PDF.
- Research the web and get answers with sources you can open.
- Analyse files: PDFs, spreadsheets and documents, including running Python on your data in the browser (Cowork).
- Keep projects with knowledge files, instructions and memory, so you do not repeat yourself.
- Use it where you work: in the browser, on Android, and on Windows with the desktop app.
Who is it for?
Students, professionals, small business owners, writers and developers in Bangladesh, and Bangla speakers anywhere, who want Claude without needing an international dollar card.
Which AI models does it use?
Claude Haiku (fast and cheap), Sonnet (the best all-round choice for writing, assignments and code) and Opus (for the hardest work). Which models you can use depends on your plan. See Claude Haiku vs Sonnet vs Opus.
How much does it cost?
There is a free plan with no card. Paid plans last 30 days and are paid once. Prices in taka and dollars are always on the pricing page. Each paid plan comes with a monthly allowance, and you can see roughly what a reply costs before you send it.
How do I pay?
In taka with bKash, Nagad, Rocket or a Bangladeshi card, or in dollars with a card, PayPal or crypto. You can also send money to the number shown at checkout and your plan is switched on after we check it. There is no automatic renewal, so you never pay by surprise.
Is it safe? Who can see my chats?
Your chats live in your own private account. Plans are never shared between people. You can export your data and delete your chats from Settings, Privacy. Read the privacy policy for the details.
Can I try it first?
Yes. Start with the free plan, or take the one-time 24-hour Pro Trial, which unlocks every model for a limited number of replies.
