Show HN: Free text classification piece for Activepieces (jeffyclassify.com)

Activepieces has introduced "Jeffy," a new text classification tool that enhances its functionality by offering 70 pretrained classifiers without relying on large language models (LLMs). Unlike traditional LLM approaches that require prompts and parsing of varied outputs, Jeffy utilizes logistic regression on frozen embeddings to deliver consistent, deterministic results. This allows users to classify text inputs for a range of applications including sentiment analysis, topic classification, and customer support routing, with outputs that are always valid JSON. The significance of Jeffy lies in its reliability and efficiency for AI/ML practitioners. By providing a straightforward integration within Activepieces, Jeffy enables quick categorization of incoming messages through a set of dropdown classifiers, making it particularly useful for businesses handling customer inquiries. With minimal latency (~15 ms locally) and the ability to self-host, users can maintain data privacy while cutting down on costs associated with LLM API calls. Additionally, if users need custom classifiers, they can easily train their own with a few labeled examples, which can be done swiftly on standard CPUs. This advances the capabilities of AI-driven text classification in practical applications, streamlining workflows and enhancing productivity.
