Scope = what workloads the tool touches. AIUsage covers any Claude API workload. Pruner/rtk/Autocache/ShadowGit/Smooth are narrower.
Mechanism public? Whether the tool explains how it cuts costs. AIUsage keeps it private — the proof is the testable audit number, not the explanation. Every other tool publishes its algorithm.
Free audit? Whether you can see your savings number before committing. AIUsage's audit is free, two-minute, and requires no signup for the number itself.
