Leading AI models debate your dilemma. You decide.

⁦GPT⁩, ⁦Gemini⁩, and ⁦Grok⁩ each think independently—and challenge you, too. Claude leads the discussion. You leave with one recommendation and a first step.

What's your dilemma?

A sample discussion, in brief

Summary

Here each stage is shown in a single line. In a real discussion, each model writes a full analysis, the facilitator asks you a few questions, and you end up with a detailed decision card.

  1. You1The dilemma

    I’ve been offered a role at an early-stage startup. Should I leave a stable job I’ve held for six years?

  2. GPT2The models

    Go for it. What you’ll learn is worth more than the security.

  3. Gemini

    Not before checking how many months of funding the company has left.

  4. Grok

    There’s a third option: ask for a part-time trial before quitting.

  5. Claude · Facilitator3Facilitator’s question

    Initial recommendation: don’t leave yet. One question: how long could you manage without a salary?

  6. You4Your take

    About six months. And I can’t work two jobs at once.

  7. Gemini5The challenge

    Without a trial, waiting effectively means saying no. You need a deadline to decide.

  8. Claude · Facilitator6Facilitator’s decision

    Take the role, provided the company has enough funding for at least a year.

    First step
    This week, ask to see the company’s finances.
    What would change it
    If the company’s cash won’t last a year, stay in your current job.

Here’s what your discussion will look like: models disagreeing, your turn to respond, a real challenge, and a decision with a first step. Your first discussion is free.

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.

How is this different from a regular AI chat?

A regular AI chat gives you one perspective and tends to agree with you. Here, several models think independently, one challenges the leading option, and the recommendation changes only when there's a new fact.

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.

Dilemmas users chose to share without identifying details, alongside the recommendations they received.

  • Career

    Should a software engineer specialize in machine learning, deepen infrastructure skills, or pursue management?

    They chose to build on their software and infrastructure experience by moving toward machine-learning infrastructure, collaborating on systems work while taking on mentoring and technical leadership.

    The recommendation:

    Go deeper into backend and infrastructure, steering toward ML infrastructure: partner with your company's new ML team on serving or pipelines as a senior engineer, and take tech-lead mentoring duties.

  • Business

    Should a freelancer quit social media, cut back, or delegate it?

    A freelancer relies on social media to attract clients but finds it draining. They are considering a minimal posting schedule, directing inquiries to email and a portfolio, and relying more on referrals from past clients.

    The recommendation:

    Go with one batched weekly post on a fixed schedule, routing inquiries to email and your portfolio, and lean on past-client referrals so Instagram stops carrying 60% of your pipeline.

  • Business

    Should they seek funding or hand over an open-source project?

    A maintainer is burning out and weighing funding options against handing over a popular open-source project. They plan to stay involved while limiting issue reports to contributors and asking organizations that rely on the project to help with triage or provide paid support.

    The recommendation:

    Keep the project but offload the issue queue: close issues to non-contributors, and ask the two heavy corporate users for triage help or a paid retainer.
