Question 1

What is Marbl Delphi?

Accepted Answer

Marbl Delphi is a cross-vendor AI oracle. Three independent AI models (OpenAI, Google, Anthropic) review the same code, plan, or architecture decision and reach consensus. Unlike a linter, Delphi answers questions rather than flagging lines. It is built for founders and technical leads who want genuine oversight before they ship.

Question 2

How is Marbl Delphi different from other AI code review tools?

Accepted Answer

Most AI code review tools use one model. Delphi uses three, from three different vendors, and surfaces disagreements rather than hiding them. It also has institutional memory - past rulings become precedent - and environment awareness, factoring in the tools and skills you actually have installed.

Question 3

Who are the three voices?

Accepted Answer

Lucian runs on OpenAI (GPT-5.4). Vera runs on Google (Gemini 3.1 Pro). Ratio runs on a strict code specialist model with Anthropic Claude Mythos planned as the replacement when available. Each has its own voice, biases, and scoring style. They argue in public so you can see the reasoning.

Question 4

When does Marbl Delphi launch?

Accepted Answer

The waitlist is open now. MVP launches in April 2026. Early waitlist members get priority access and founding-member pricing.
