SynthBoardvsCrewAI

CrewAI is a kit.
SynthBoard is the room.

CrewAI gives developers the parts to build their own crew of agents. SynthBoard is the finished product for one job: bringing a hard call to named experts who argue it, and keeping what you decided.

What it’s good at

Build any multi-step workflow in code
Full control over prompts, tools and models
Open source

SynthBoard runs from code too: the REST API and the MCP server.

What a board adds

Named experts who hold a position, on different AI models
On a decision, two are assigned opposite sides
The call, how sure the board is, and who disagreed and why
Your world on file, work and home apart, and a first step with a date

24 named experts on the bench

One call, side by side

Same question.
A different kind of answer.

A business call, typed the way a person types it: the board’s run, next to the shape of what CrewAI would hand back. An example, trimmed for length.

Build our own support agents, or buy?

Work · Board of 3

Support gets 1,200 tickets a month. We could build our own AI agents on an open-source framework with our two backend engineers, or buy a support AI at about $1 per resolved ticket. Which?

Chief of staff

Your board is seated: The Engineer, The CFO, The Security Chief. They read the brief first, then research, then argue it out.

The board’s call

Buy for now. Run the vendor on a quarter of your tickets for a month, and build only what it can’t handle in your top three ticket types.

At about $1 per resolved ticket, even all 1,200 tickets cost about $1,200 a month — far less than two engineers building an agent stack and keeping it running. The pilot shows what the vendor can’t do before you build anything.

Confidence67 · Moderate

The Security Chief disagreed

“A vendor reads every ticket, with your customers’ data in it. No pilot until their data-handling terms are signed.”

Can developers use SynthBoard from code?

Yes. The same boards run from the REST API and the MCP server, with signed webhooks when a room lands.

Why not build this with CrewAI?

You can build agents that talk to each other. What takes longer is what sits around them: experts that hold a position, seats spread across model families, a memo that keeps the dissent and caps its confidence, a memory of your decisions, reads and confirm-first writes in your tools.

Is every question a board?

No. Your Chief of Staff answers the everyday herself. A question that needs one expert becomes a consult; only the biggest calls go to a board. Talking to your Chief of Staff is free within a daily allowance. A consult or a board shows its price on the card before anything runs, and nothing runs until you tap.

What if the experts are wrong?

They can be: the experts are AI. That is why every memo shows how confident the board is, what would flip the call and who disagreed, and why the call stays yours.
