As answered by people managing TribunalOfIdeas.com.br and Diffyn.
TribunalOfIdeas.com.br's answer
Most AI validators give a fast, flattering score from a single model. Tribunal of Ideas puts your idea on trial before a courtroom of 25 different AI models: prosecutors attack it, defenders respond, deliberately biased witnesses testify for and against, 12 jurors score it across 9 equally weighted criteria, and a judge delivers a verdict calculated by a formula, not decided by any model. Every score is anchored in real market evidence with linked sources.
Diffyn's answer:
Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.
TribunalOfIdeas.com.br's answer
Because the verdict is adversarial, evidence-based and calculated, not one model's opinion. A market search surfaces documented pain points and named competitors with sources before any argument, multiple different models debate to cut down on hallucination, jurors cross-review each other anonymously, and every trial includes a free appeal. You get a defensible verdict and an action plan, not a number meant to make you feel good.
Diffyn's answer:
Diffyn is the platform that specializes on both change management and multi-model analysis.
TribunalOfIdeas.com.br's answer
A modern web app that orchestrates multiple frontier LLMs in parallel, one per seat of the trial, on top of a market-search evidence layer and a calculated scoring engine.

TribunalOfIdeas.com.br's answer
Founders, indie hackers and product people who want an honest read on a startup or product idea before investing time or money, and who are tired of AI tools that agree with everything.
Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
TribunalOfIdeas.com.br's answer
It was built to fix a real problem: most AI tools flatter your idea instead of stress-testing it. Tribunal of Ideas turns idea validation into an adversarial trial, so the weak points surface before you build.
Diffyn's answer:
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
