How brainsto works
Several leading AI models examine your dilemma independently. In about a minute, you get an initial recommendation. You respond, the panel debates with you too, and you leave with one decision and practical next steps. No model agrees with you just to please you.
How it works: four steps
1
Each model thinks independently
Each model examines your dilemma on its own, chooses a direction, makes a strong case against it and looks for a better solution than the one you proposed.
2
An initial recommendation, without a long wait
The facilitator weighs the arguments without knowing which model wrote what, then forms one clear recommendation. If a missing fact could change that recommendation, it asks up to two questions.
3
Now it’s your turn
Answer the questions, fill in the gaps or simply confirm. A new fact can change the recommendation. A preference alone cannot.
4
Challenge, then decide
One model challenges the leading direction, while another looks for what’s missing from the picture. You leave with one recommendation and practical next steps. The full analysis is a click away.
Who weighs in on your dilemma

Each company’s flagship AI model joins the discussion and assesses your dilemma independently. You pay per discussion, rather than for a separate subscription to each model.
The facilitator insists they challenge you, not tell you what you want to hear.
Each participant answers separately and never sees the others. The facilitator does not know which model wrote what, so it judges arguments, not names.
More than a single chatbot answer: several leading AI models examine your dilemma from every angle, debate each other, and challenge you too. You leave with a clear decision: which way to go, why, and what to do first.
Leave with a clear decision, on one card
An example from a real dilemma, with identifying details removed.
The decision
The dilemma: A wedding gift: give a potted herb plant I grew myself, or just give money?
The recommendationA creative solution
Give the potted herb with a modest cash gift and a short, personal card.
The steps
- Choose a hardy herb today that can survive a week without care.
- Decide on the amount before the wedding, not on the day itself.
- Write in the card why you chose this particular plant.
Why
This makes the gift personal and memorable, without making it look like a way to save money.
What you give up
You give up the simplest option: giving cash alone.
What would change the recommendation
If you know the couple expects only cash, give cash and save the plant for another occasion.

Frequently asked questions
What is brainsto?
A service where several leading AI models examine your dilemma independently. They debate each other and challenge you, too. The facilitator brings it all together into one recommendation and practical steps.
What does it cost?
Your first discussion is free. After that, $1.99 per discussion, or $1.20 per discussion with a bundle. No subscription. You only pay when the discussion gives you an answer.
How is this different from a regular AI chat?

How long does a discussion take?
You'll get an initial recommendation in about a minute. Then you respond, and the models keep going until there's a decision and practical steps.
Who sees what I write?
Your text is sent to model providers only for the discussion, under their API terms. No ads. No tracking. Only you decide whether anything from the discussion is shared.
