Everything in one place
More than a chat box
Five ways to work, built around the things you actually need to finish: documents, answers you can trust, and files you can hand in. See every feature.
Deep Research
Searches the web many times, compares sources and writes a cited report you can check.

Cowork on your files
Upload a sheet and ask. It writes and runs Python right in your browser and hands you the result files.
Projects that remember
Add files and instructions once. Every chat in the project uses them without uploading again.
Talk in Bangla or English
Dictate with your voice, hear answers read aloud, and switch languages whenever you like.
Code that runs
Build small apps and calculators, preview them live, run JavaScript and Python, and download the files.
See the cost before you send
Every model shows roughly what a reply costs and how many you have left, so you can pick the cheapest one that does the job.

What is Duplibot?
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.
Is there a free plan?
Yes. The Free plan includes the Haiku model and a small monthly allowance. You do not need a card to sign up.
Can I use it in Bangla?
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.
Do I need to install anything?
No. Duplibot runs in your web browser on a phone, tablet or computer.
How do I pay?
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.
Will I be charged automatically every month?
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.
How does the monthly allowance work?
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.
Can I get a refund?
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.
Why is it cheaper than an official AI subscription?
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 free in under a minute
No card needed. Upgrade only when you need more.
