# SynthBoard vs Claude

> Claude is one of the best single AI assistants and is one of the providers SynthBoard uses internally. They are not direct competitors — but if you are using Claude alone to make strategic decisions, you are leaving structural disagreement on the table.

## TL;DR

| | Claude (Pro / direct) | SynthBoard |
|---|---|---|
| Architecture | Single AI (Anthropic only) | Multi-LLM, multi-agent (OpenAI + Anthropic + Google) |
| Optimization | Helpfulness, safety | Structured disagreement |
| Personas | One assistant | 24 expert Synths, 6-layer persona stack each |
| Memory | Per-conversation | Cross-session, decision-aware |
| Outcomes | None | Inferred from connected tools |
| Action governance | None at product layer | Approval-gated, 30s undo, full audit |

## What Claude does well

- Long-context reasoning (200k+ tokens).
- Careful, well-calibrated answers.
- Code review and refactoring.
- Long-form writing.
- Following complex instructions.

We use Claude inside SynthBoard — it is one of the best models for several Synth personas, and our routing layer assigns Claude to the Synths whose reasoning style fits it best. Outside SynthBoard, Claude direct is excellent for any of the use cases above.

## Where Claude alone falls short for decisions

Even Claude — which is more conservative than other models about agreeing with users — runs into the same structural failure mode for strategic decisions. A single AI cannot disagree with itself. You can prompt it to "play devil's advocate" but the underlying gradient still pulls toward the user's framing. The output is one perspective, smoothed.

For decisions where the cost of being wrong is high, you want:
- Multiple agents with different priors.
- Multiple model providers (so you are not exposed to any single provider's blind spots).
- Persona-level position integrity (so an agent does not collapse to agreement under pressure).
- A synthesis layer that preserves disagreement.

These are structural properties Claude alone cannot provide. They are what SynthBoard is for.

## What SynthBoard adds

1. **Multi-LLM, multi-agent.** Synths assigned to OpenAI, Anthropic, and Google based on persona fit. Frontier reasoning models matched to each Synth's cognitive style — no single provider's blind spots dominate the board.
2. **24 expert personas.** Each with a 6-layer persona stack including position-integrity rules.
3. **Cross-session memory.** Past decisions inform future ones automatically.
4. **Outcome inference.** The board learns from what actually worked in your tools.
5. **Action governance.** Approval gates, audit trails, 30-second undo on every action.
6. **10 session modes.** Each shaping the board's behavior for the decision type.

## Pricing

- Claude Pro: $20/month — single user, single AI, ~5x rate limit increase, access to Sonnet and Opus.
- SynthBoard Pro: $20/month — 5 Synths per session, multi-LLM (including Anthropic Sonnet via Synths), all 10 modes, integrations.

Same price, different category. Claude is a chat product. SynthBoard is a decision product.

## Use both

If you make any meaningful number of strategic decisions, the right configuration is both:
- **Claude** for long-context analysis, code, and writing.
- **SynthBoard** for the calls where you need structured pushback.

SynthBoard's API and MCP server let you invoke a board *from inside* Claude Desktop. Convene a board on a question without leaving the Claude app.
