PureFeed is a content quality filter for Reddit, YouTube, X, and LinkedIn. AI scores every post on negativity, sensationalism, usefulness, learning, and opportunity - you set the thresholds, and low-signal posts collapse into a "Why was this hidden?" card. Nothing is silently removed, everything is reversible. You don't have to quit social media - you just stop drowning in junk. Free up to 500 posts/day. Pro adds custom profiles, per-creator scoring, and no limits.
