Clavero brings structure to your thinking so that your AI agents can build with complete clarity.
See it in action — watch a belief change cascade through your reasoning
One assumption questioned. Two commitments flagged. Your reasoning just got more honest.
State what you believe. Link evidence for and against. See when your logic breaks down. Clavero enforces the reasoning disciplines used by the world's best decision-makers — falsifiability, calibration, evidence quality — as a natural part of your workflow.
One command connects Claude to your beliefs, your reasoning, your constraints. Your agents don't just know what to build — they understand why. Generate implementation specs grounded in your full strategic context.

Log every decision with reasoning and assumptions. Reflect on them 30 days later. Over time, Clavero reveals your patterns — where you're sharp and where you consistently get it wrong.

Your beliefs, your evidence, your strategic position — all connected.
Every layer connects to the next. When you change a belief, you see the impact on every decision. When you learn from an outcome, that learning updates your beliefs.

Not a framework. Not a course. A tool that enforces the reasoning disciplines used by the world’s best decision-makers — Kahneman, Tetlock, Munger, Annie Duke — as a natural part of how you work.
Every belief must answer: what would prove this wrong?
Clavero nudges you toward specific, testable beliefs. "We should focus on enterprise" isn't a belief — it's a preference. "Enterprise companies with 500+ employees will pay $50K+ within 6 months" is a belief. The difference matters.
Not all evidence is equal. Clavero knows the difference.
One anecdote from one customer is weaker than a pattern across ten. Clavero scores your evidence base: source diversity, recency, direction balance. You see where your reasoning is grounded and where it's thin.
Are you sure? Your evidence says otherwise.
When your confidence exceeds your evidence, Clavero tells you. When you're being overly cautious despite strong data, it tells you that too. Over time, it tracks your calibration — helping you understand your own biases.
It's six months from now and this failed. What happened?
Before you commit, Clavero generates plausible failure scenarios grounded in your actual evidence gaps and untested beliefs. You see the risks before the money is spent.
What's the strongest case against your position?
Before you dismiss an alternative, Clavero constructs the best possible argument for it. If you can't engage with the counter-argument, you haven't actually thought it through.
These two commitments are working against each other.
Clavero continuously monitors your reasoning for inconsistencies — beliefs that conflict, commitments that pull in opposite directions, decisions that contradict your stated position. Not a quarterly review. Continuous.
Clavero connects to Claude Code via MCP. One command. Every session has access to your beliefs, your design principles, your decision context. When you generate a spec, the agent receives reasoning that no other tool provides.
You can also capture insights from any Claude conversation directly into Clavero. Mid-conversation, say “save that to Clavero.” The insight becomes evidence, linked to your beliefs. Your thinking gets richer as a byproduct of conversations you’re already having.

> What are my current beliefs about the enterprise market?
You hold 3 beliefs about enterprise:
[HIGH] Enterprise buyers need SSO before procurement approves
[MEDIUM] Enterprise deals require champion + executive sponsor
[UNTESTED] Enterprise will pay 10x mid-market pricing
> That insight about SSO from today’s call — save it to Clavero
Captured: “SSO confirmed as procurement blocker in 4th consecutive deal”
Evidence linked: supports “Enterprise buyers need SSO” (pattern)
