defluff runs on your own machine — the client starts it, so there is no endpoint to ping. 90 installs a week from pypi. Last commit 28 Jun 2026.
Deterministic prose linter for LLM text — flags AI slop, filler, buzzwords, hedges, clichés.
Today is the operative word: we check defluff every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
