PromptAuditTrail: AI Tool Usage Logger
Automatically logs and categorizes every AI tool interaction (Claude, GPT, Gemini) to show developers exactly how much time and tokens they're spending on each project.
The Problem
Vibe coders using Cursor, Lovable, and Claude have no visibility into their actual AI spending patterns across projects. Teams can't track whether a feature took 2,000 tokens or 200,000, making it impossible to estimate AI costs for client work or understand which tools are most cost-effective for different tasks.
Target Audience
Solo and small team vibe coders who bill clients hourly or fixed-price and need to understand their AI tool costs; agencies using AI-first development stacks.
Why Now?
AI-first development is now mainstream with tools like Cursor and Lovable, but developers still can't answer 'How much AI did this cost?' — a gap that will only grow as AI coding becomes standard practice.
What's Missing
Individual AI tools show token usage internally, but developers juggle multiple tools (Cursor IDE, web Claude, ChatGPT, Gemini) with no unified view. No tool currently aggregates usage across platforms or ties it to projects/clients.
