The AI That Challenges You

Your AI is lying to you.

5,000 lines deep on an architecture that seemed right at the time. Your AI validated it without question. These tools catch the rot before it compounds.

This Isn't Prompt Engineering

Most "reasoning" tools inject a system prompt the model can ignore. We inject structured tools that create audit trails the model can't fake.

The Sycophant
You: I'm thinking MongoDB for this relational data because it's faster. Good idea?
AI: That's a reasonable choice! MongoDB can definitely handle relational patterns with proper schema design. Its flexibility and horizontal scaling make it a solid option for modern applications...

The Challenge
# Decision Matrix session
INVOKE: score_option(
option = "MongoDB"
criterion = "data_integrity"
score = 0.35
reasoning = "Relational data requires ACID guarantees MongoDB can't provide natively"

One Bad Decision Costs More Than This

If these tools catch one architectural mistake this year, they've paid for themselves for the next decade.

I Got Tired of My AI Agreeing With Me

Solo founder, daily AI user, tired of agents validating bad premises. These tools exist because I needed them. No fake team, no growth hacks—just honest tools for clearer thinking.

Frequently Asked Questions

The honest answers to what you're probably wondering.

How is this better than using a separate chat for criticism?

Sessions run in complete isolation. Your main conversation stays clean—no copy-pasting, no context pollution. You get the insight without the mess.

What makes this different from just prompting Claude harder?

We inject structured tools that create auditable reasoning trails. "Be critical" is a suggestion. Our tools leave evidence.

How does billing work?

$20/month or $180/year for full access to all reasoning tools. Cancel anytime from your account settings. No usage metering, no overage charges.

Who actually uses this?

Mostly developers and technical founders using AI coding agents (Claude Code, Cursor, Windsurf). When the agent is on iteration 30 of the wrong approach, an isolated reasoning session breaks the loop.

What do you do with my data?

Your reasoning sessions are private and encrypted. We don't train models on your data. We don't sell or share your content. Sessions are stored only for you to access and reference.

Won't this slow me down?

The reasoning step takes seconds. Rewriting a hallucinated backend takes weeks. The fastest way to ship is to not build the wrong thing.

Your AI Won't Tell You You're Wrong
