AI Prompt Cost Profiler

Derivation Chain

Step 1 OpenAI's astronomical operating costs raise profitability warnings
→
Step 2 Prompt engineering inefficiencies in AI SaaS
→
Step 3 Developer tool that profiles per-prompt token consumption and response quality correlation

Problem

AI SaaS development teams iteratively refine prompts to improve quality but lack systematic tracking of the trade-off between token consumption and response quality per prompt version. System prompts silently bloat, doubling or tripling input tokens per request without anyone noticing, resulting in hundreds of dollars in unnecessary monthly token costs.

Solution

Add a single-line wrapper to existing LLM API calls to automatically log token consumption, response time, and quality scores (user feedback or auto-evaluation) per prompt version, then visualize the cost-quality Pareto frontier. Also provides prompt compression suggestions for token savings.

Target: Prompt engineers and AI SaaS backend developers at teams of 3–20 people building LLM-based services
Revenue Model: Usage-based: up to 10,000 requests/month free, then $0.75 per 1,000 requests. Team Plan (5 users, shared dashboard) at $37/month
Ecosystem Role: Supplier
MVP Estimate: 2_weeks
