BiasChecker.ai

BiasChecker for Chrome

It reads along with you. One click, and a panel beside the article or YouTube video you are on gives you an expert reading of it: the slant and what is left out, whether the argument and the science hold up, the legal and moral angles, the background, and a synthesis of it all. Highlight a passage to analyse just that. Nothing to copy or paste.

    15 models from 7 makers, all current and all strong, and each notices different things. Pick one for everything, or one per analysis.
    The model picker open in the side panel, listing models from several makers, each with its cost multiplier

  • See where the AIs agree, and where they do not.

    Compare runs the same analysis on several models and shows their verdicts side by side, for you to weigh. Consensus runs them too, then merges them into one result.

  • One merged result.

    Consensus keeps what two or more models found, and shows what only one saw under its name. Offered on Bias, Persuasion, Legal, Moral and Science.
