TokenShrink compresses LLM prompts before they hit the API — stripping filler, hedges, and bloat without changing meaning. 100+ regex rules run in under 2ms. No API calls. No cost. Never touches code blocks or URLs.
Works as CLI, MCP server, and browser extension. English + Turkish. Optional Groq upgrade for LLM-quality compression (14,400 free req/day).
Opus 4 costs $15/M tokens — a heavy user spends ~$68/yr on input. TokenShrink cuts that in half. For teams of 10, that's $680/yr saved.

The fix seemed obvious: strip the fat before the message ever leaves your machine. No roundtrips to an LLM, no latency, no cost — just regex that runs in 2ms. What surprised me was how much filler survives editing. Even technical writers...
