Meatbags suck at spotting lying LLMs, so let AI narc on itself
LogicLens uses AI to review articles, social media posts and other content for factual inaccuracies, weak reasoning and signs of polarisation. Its creators say it provides context and cited sources so users can make their own judgements, rather than acting as an arbiter of truth.
The service is available as a Chrome extension and as an iOS app called Receipts. LogicLens does not name the models behind it, but says its system is designed to outperform general AI models and trained experts. A 2024 study found AI-generated misinformation more convincing than human-written material; the service is free with limits of 15 analyses a day and 100 a month, or $4.99 monthly for unlimited use.
In short
- LogicLens uses AI to flag possible errors and flawed reasoning.
- It is available on Chrome and iOS.
- Free users get 100 analyses a month; unlimited use costs $4.99 monthly.
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Tools such as LogicLens could help people assess claims more carefully by flagging weak reasoning, possible inaccuracies and polarising language, while giving them sources to check for themselves. If its creators’ performance claims hold up, it may offer a useful, accessible first review of content that readers would otherwise struggle to evaluate unaided.
The case against
An AI system can make mistakes or reflect biases in its training and design, so presenting its analysis as a check on misinformation may give users misplaced confidence. The service does not identify its underlying models, and its claims of outperforming experts need independent scrutiny; readers may be better served by treating its assessments as one fallible input rather than relying on AI to judge AI.
