Which problem are you solving?
Your AI Validates. These Tools Challenge.
One conversation breaks the loop. The other structures the decision. Both run in isolated sessions so your main workflow stays clean.
Works With Your AI. Not Instead Of It.
Claude Code, Cursor, Windsurf, Copilot—bring your own. One Reasoning Services account adds structured thinking to ALL your AI workflows. No lock-in."My Agent Is Stuck in a Loop"
Your coding agent (Claude Code, Cursor, Windsurf) is on iteration 30 of the wrong approach. Each attempt builds on the last, sinking deeper into a flawed mental model. The agent's context is polluted.
What you need: A fresh context session to articulate the actual problem. The bug becomes obvious when you explain it out loud.
Break the Loop →"I Can't Afford to Get This Wrong"
Database choice, vendor selection, hiring decision. Multiple stakeholders. Expensive to reverse. Your gut has a favorite, and your AI validated it in seconds. But you need more than agreement—you need justification.
What you need: Weighted criteria, sensitivity analysis, documented reasoning that survives scrutiny.
Structure the Decision →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.
Four Tools. Four Failure Modes Your AI Won't Catch.
Your agent validates. These tools challenge. Each targets a specific way AI-assisted thinking goes wrong.
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
