# RedSutra - AI Reddit Replies That Sound Like You, Not a Bot

> Last Updated: 2026-02-05
> Version: 1.0.5
> Category: Chrome Extension / AI Writing Tool / Reddit Tool

RedSutra is a free, privacy-first Chrome extension that generates Reddit replies matching your unique voice and personality. Unlike generic AI tools that produce robotic, detectable output, RedSutra uses your persona settings (profession, interests, writing style) to craft authentic replies that sound like you actually wrote them. No accounts, no servers, no data collection.
