Frequently asked questions

Duplibot is an AI workspace. You chat with Anthropic's Claude models (Haiku, Sonnet and Opus), write and export documents, research the web with sources, and work on your files, all in one place. It is an independent product and is not affiliated with Anthropic.

Yes. The Free plan includes the Haiku model and a small monthly allowance. You do not need a card to sign up.

Yes. Ask in Bangla, English or a mix of both, by typing or with your voice. For very formal or technical Bangla, read the result before you send it on.

No. Duplibot runs in your web browser on a phone, tablet or computer.

In taka through bKash, Nagad and Bangladeshi cards, or in dollars through PayPal, cards and crypto, depending on which methods are switched on. You pay once for 30 days.

No. Plans never renew by themselves and no card is saved. When 30 days end, your account moves to the Free plan until you pay again.

Each plan includes an allowance for 30 days. Short answers on small models use very little; long documents, big files, deep thinking and Research use more. You always see roughly what a reply costs and how much is left.

Yes, within 7 days if you have used less than 10% of the allowance, and always for double payments or payments that did not activate your plan. See the Refund Policy for details.

You pay for what you use. Most people do not need unlimited access to the biggest model every day, so a plan sized to your use costs far less, and paying in taka avoids international card fees.

Start with Haiku for quick questions, translation and summaries. Use Sonnet for writing and coding, and Opus for hard problems and careful long documents. The model picker shows what each one is best for and its cost per reply.

Research mode searches the web many times, reads the most useful pages and writes a report with numbered citations you can check. It is part of the Pro plan and above.

Cowork works on your files step by step. Upload a spreadsheet or document and describe the task; the AI writes Python, runs it in your own browser and gives you the result files.

PDF, Word, Excel, PowerPoint, CSV, text, images, code and many more: 84 file types in all, up to 20 MB each.

Yes. Documents export to Word (.docx), PDF and Markdown, and you can export a whole chat or share a read-only link.

No. Every account belongs to one person, with its own login and private history. Nobody else can see your chats or files.

Your chats are visible only to you. Messages are sent to the AI model provider to produce answers. We do not sell your data or use it for advertising, and we do not use your chats to train AI models.
