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.

Why does ChatGPT always agree with me?

AI models are trained to be helpful and avoid conflict, leading to sycophantic behavior. They validate your ideas instead of challenging them. Our tools use structured tool calls that force systematic evaluation, preventing the AI from simply agreeing.

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 do not train models on your data. We do not 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.
