| What makes it different | - Achieves 25-50% token reduction on typical Claude Code sessions without requiring model subscription upgrades
- All compression runs locally on your machine with no data sent to servers
- Reversible compression preserves output quality and allows retrieval of original content on demand
- Works transparently with existing IDE extensions and agent runners without workflow changes
- Built on open-source Headroom CLI engine available free on GitHub
| - Eliminates 95% of LLM token overhead through deterministic compiler verification instead of probabilistic inference loops
- Operates locally with strict Zero Code Retention policy—no code logging, storage, or model training usage
- Sub-microsecond repairs in CPU L1 cache without garbage collection pauses via native Rust FFI
- Engineered as M2M sub-cortex infrastructure for autonomous agents, not consumer chatbot utility
