How it works

How BestAnswersAI works: 4 AI agents and a judge

BestAnswersAI is built on an idea called mixture of agents. Instead of trusting a single model's first draft, several agents answer the same question, critique each other, and a final step combines what survived. The goal is fewer blind spots than any one response would have.

The mixture of agents idea

A single chatbot gives you one confident voice, with no way to tell a careful answer from a fluent wrong one. When several independent drafts exist, the disagreements between them become a signal: they point to the parts of an answer that deserve doubt. BestAnswersAI turns that signal into a process you can see.

The four agents

Each agent is a persona with its own system prompt, modelled on the answering style of a well known assistant. All four currently run on Google Gemini, so the diversity comes from prompt design rather than different vendors.

Agent Gemini

Breaks the question into facets and covers each one systematically, grounded in concrete facts, with tables for comparisons.

Agent ChatGPT

Works out what you most likely need, explains it clearly with analogies, and ends with a natural next step.

Agent Groq

Answers in the style of xAI's Grok: gives the blunt bottom line first, calls out the common misconception, and optimises for what you should do.

Agent Claude

Answers the real intent behind the question, weighs trade offs openly, and states uncertainty instead of overclaiming.

From question to verdict

1. 01Ask. Type any question once. Deep mode sends it to every agent you have switched on; Quick mode asks a single agent for a fast answer.
2. 02Agents answer in parallel. Four agent personas draft their answers at the same time, each in its own style: structured and factual, direct and practical, friendly and explanatory, or careful about trade offs.
3. 03Peer review. Each agent reads the other drafts and votes for the best one, so weak or unsupported answers lose before you see them.
4. 04Judge synthesizes. A judge tallies the votes, breaks ties, and writes one verdict that merges the strongest points and credits what each agent contributed.

Peer review and the judge

In peer review, every agent sees the other drafts and votes for the strongest one. The judge then tallies the votes and breaks any tie, and writes a single master answer. It does not simply pick a winner: it merges the best supported points from every draft and credits what each agent contributed, so you can see where the verdict came from.

What you see with each answer

• Response time and estimated tokens and cost for every agent
• Follow up question suggestions after each verdict
• Copy, download as Markdown, share, and read aloud
• History saved in your browser, plus dark and light themes
• Bring your own Gemini API key in Settings

Limits

Agreement between agents is not proof. Because all four agents currently share one underlying model family, they can share the same blind spot, and every answer can still contain mistakes.
