AI detection startup Pangram has secured $9 million in funding, led by Menlo Ventures with participation from Haystack, ScOp, Script Capital, and Cadenza. The investment coincides with the launch of Pangram's enhanced AI text detection model, Pangram 4, and a new AI image detection model, Pangram Image. Pangram 4 reportedly achieves over 99% accuracy in identifying AI-assisted writing and mixed human-AI content. The Pangram Image detector is currently in a research preview phase, with broader availability expected soon. Co-founders Max Spero and Bradley Emi established Pangram in response to the surge of AI-generated content following ChatGPT's release. Spero emphasized the value of knowing content origin to influence reader perception and trust, distinguishing journalistic work from potential AI hallucinations or disinformation. Pangram's detection system is trained on millions of human documents and synthetic mirrors generated by LLMs to learn stylistic differences. The company's technology also aims to distinguish varying degrees of AI assistance. Instances like a Canadian politician reading an AI prompt aloud and lawyers using AI-generated fake citations highlight the need for such tools. Institutions are also implementing policies, such as arXiv's one-year submission ban for authors failing to review LLM output. Pangram faces competition from startups like Winston AI, Originality.ai, Copyleaks, and GPTZero. Pangram's technology is accessible via a $20 monthly subscription, a Chrome extension, and an API for partners like Substack and Quora.
