About OneBrain / Built by DigitX
Imagine what you could learn, make or build if powerful AI felt possible to use every day. OneBrain brings efficient models for the ordinary moments and frontier models for the big ones into one app—so the cost of getting started does not decide how far you can go.
Our mission01 / Our mission
Too many people see what AI can do, then feel the door close when they see the cost.
We built OneBrain because curiosity, ambition and good ideas are not limited to people with the biggest budgets. Our mission is to make a powerful AI app experience more accessible: a free place to begin, efficient models for everyday work, and a path to flagship models when the task calls for them.
OneBrainA new chapter
Development support through Anthropic’s Claude Startups program.
Built in Bangladesh. Accepted into Claude Startups. OneBrain AI by DigitX is taking another step toward making powerful AI accessible to more people.
The initiative provides development resources and guidance to support the people building OneBrain—and the work we want to make possible for you.
OneBrain customer access continues to follow the terms of each OneBrain plan.

02 / Our vision
We want a student with a question, a creator with an idea and a small team with too much to do to feel the same thing: I can start here. As their work grows, OneBrain should grow with them—from a simple conversation to creation, connected tools and real work they can review and trust.
03 / Why Bangladesh, why now
The world is racing toward more capable AI and already talking about superintelligence. But progress elsewhere does not automatically become opportunity here. If access is expensive, confusing or built around payment methods people cannot use, too many promising ideas never get a chance to begin.
OneBrain is our contribution to closing that distance: an AI app built in Bangladesh, with a free place to start, efficient models for everyday needs, a path to frontier models and local ways to pay. No single product can solve a country's AI-readiness gap. We can make today's powerful tools easier for more people here to actually use.
Rooted in Bangladesh. Open to what comes next.

04 / The experience
Use the capability the moment calls for, without having to leave your work behind.
Ask the question, understand the hard thing, write the first draft. Leo uses smaller, faster models for the everyday moments that move you forward.
Open ChatWhen a decision, research task or piece of code needs more depth, Atlas can route to flagship models on eligible plans. Your work stays in the same place.
Choose in ChatMove from answers to plans, files, creative work and connected agents. OneBrain helps carry the work forward, with your review before sensitive actions.
Explore Work05 / Access that grows with you
You should not need the most expensive model to write a quick note. And when the work truly needs more, you should have a clear way to reach it. Start free; paid plans range from Leo's smaller, faster models to Atlas's flagship routing and direct model choice. Work, Creation and agent access vary by plan, and media generation uses separate credits.
Built in Bangladesh by DigitX, OneBrain supports plans in BDT and local payment options. Because access is also about being able to pay in a way that works where you live.
