Show HN: Tab Council – turn your AI tabs into a model council (github.com)

Tab Council, a new Chrome MV3 extension, enables users to transform their existing AI tabs into a structured model council to collaboratively evaluate prompts across multiple AI platforms like ChatGPT, Claude, and Gemini. Users create a tab group named "tab-council," input their AI provider tabs, and execute a multi-round process involving independent answers, critiques, and synthesizing final outputs. Notably, Tab Council operates completely locally without requiring any API keys, enhancing privacy while facilitating collaborative decision-making in various contexts such as product reviews and policy drafting. This tool is significant for the AI/ML community as it emphasizes a more rigorous approach to evaluating AI-generated responses, allowing direct comparison and critique among different AI models. By assigning explicit roles like Member, Judge, and Validator, Tab Council ensures a structured debate, which can uncover nuances in AI reasoning and improve the reliability of the synthesized conclusions. The extension's innovative JSON repair feature and strict output handling enhance the quality of the interaction, making Tab Council a valuable resource for anyone looking to leverage AI capabilities critically and collaboratively.
