PromptFold

PromptFold was built to help teams cut LLM input costs without sacrificing quality, for free. It’s completely lossless, fast, and achieves up to 30% reduction in input tokens — benchmarked on open-source chat dialogue datasets. What makes it unique among prompt compression tools: 1. Lossless: PromptFold doesn’t alter meaning or task intent at all, so it’s safe for production use across agents, chatbots, and RAG pipelines. 2. Low-latency: achieves >60ms response time averages at scale. To make it accessible to anyone using LLMs, it is completely free. Would love your feedback!
