Real boards cost $50K+/year. SynthBoard starts free.
Choose your experts
Watch a hard call move through the room — assembled, argued, recorded, learned.
Drop your brief — a question, a tension, a call you're trying to make. SynthBoard assembles the experts most likely to disagree on it. No prompting, no setup — just a board built for the question.
AI is built to please. Synths are built to argue — engineered to hold position under pressure.
Should we expand into the European market?
Connect Stripe, HubSpot, Calendar, Gmail. After every call, your board watches what actually happens — a customer signed, a deal stalled, a hire onboarded — and quietly learns. Six months in, your board knows what works for your business — and what doesn't.

Most AI tools give you chat. SynthBoard gives you a strategy stack.
Forget reading transcripts. After each round, SynthBoard extracts ranked ideas, key disagreements, action items, or confidence-weighted recommendations — adapted to your decision type.
Don't see the perspective you need? Create it. Describe how they think, tune their personality, upload your strategy docs — you've built a permanent advisor for any future decision.
Every synth, summary, and insight — generated natively. RTL-perfect for Hebrew and Arabic. No translation layer.
Tell synths who you are and what you're working on. Upload PDFs, briefs, screenshots — synths reference them throughout the debate.
Slack, Stripe, HubSpot, Calendar, Gmail, Notion, Linear, GitHub — 60+ tools your synths can read from and write to. Full audit trail on every action.
Deep-dive with any single expert. Or fire up the Session Assistant — a research analyst that's read the entire debate and answers in structured insights, with web search and citations.
Drive sessions from your stack. Or let your stack drive sessions.
Pivot calls. Hiring decisions. Career moves. The question you've been avoiding. A team of real experts for anything that matters.

ChatGPT gives you one perspective — and it tends to agree with whatever you say. SynthBoard gives you a full team of AI experts, each with real personality, cognitive reasoning frameworks, and genuine domain expertise. They bring different stances, challenge each other's thinking, and then our consensus engine synthesizes everything into a clear recommendation with confidence scores. It's the difference between asking one person for advice vs. having a team of experts think it through together.
