ProPrompt Purse
A local proxy that sits between your IDE and any LLM API (OpenAI, Anthropic, Groq). It caches repeated prefix prompts, compresses context by summarizing older messages, dynamically switches to cheaper models when confidence is high, and provides a real-time cost dashboard per project. Also auto-generates weekly waste reports.
Target Audience
Freelance full-stack developers who pay out-of-pocket for AI coding tools like Copilot, Cursor, or direct API usage, spending $200+/month on tokens while building client projects, and lack visibility into what queries are expensive.
Why Now
HN front-page post 'I burned all my tokens researching how to save tokens' and Dev.to 'I burned through thousands of AI tokens. Then a friend did it for free' this week. GitHub trending 'airllm' (compression) and 'ktransformers' (efficiency) show the technical feasibility of optimizing token consumption.
