About Promptive Sentry

Claude cuts you off without warning. I built Promptive Sentry to fix that — a free Chrome extension that shows Claude's invisible usage limit as a live meter so you always see it coming. Plus a prompt enhancer that rewrites your inputs and shows before vs after before anything gets sent. Free. Private. Instant.
