The decision workbench
you steer.

KOU is a structured workbench for decisions. Give it one question, and Claude drafts an answer, Gemini reviews that draft for errors, gaps, and overconfidence, and Grok checks the claims against a live web search. Three models, three distinct jobs, working on one answer.

A single model tends to agree with you. Having it critique its own answer doesn't help much either — the same model tends to repeat the same blind spots. KOU hands the critique to a different model, and grounds the result in an actual web search. That's not a conversation. It's a verification process.

Most multi-model tools sell breadth — modes for debate, summarizing, collaboration, and more, a general-purpose toolbox. KOU is built for one job: decisions. It has a fixed sequence (draft, verify, evidence) and a human who steers every round.

Not access to Claude, Gemini, and Grok themselves — subscribing to all three separately runs close to $60/month. What KOU provides is the pipeline that connects them in the right order, and the part that turns the discussion into a single decision memo you can grow, edit, and take with you.

Research shows that having multiple AI models critique each other's answers improves factual accuracy and reasoning over a single model (Du et al., 2023, among others). But the same research shows limits: weaker models tend to conform to the majority, and debate without new information tends to go in circles. That's why KOU uses distinct models, lets you intervene every round, and lets you invite a real person into the debate. The loop never stays closed — there's always a way to bring in a new perspective.
