PureFeed alternative: Smart Filter compared with PureFeed
Smart Filter is a free Chrome extension that hides posts that match rules you write, in your own words or as keywords. PureFeed, also an AI feed filter, scores posts on fixed measures such as negativity and sensationalism and hides those above your thresholds.
Smart Filter and PureFeed in short
Smart Filter and PureFeed 1.3.1 by Nexlr are Chrome extensions that hide posts with AI. PureFeed scores posts on Reddit, YouTube, X and LinkedIn on fixed measures such as negativity and sensationalism and hides those above your thresholds. Smart Filter hides posts that match rules you write: an AI rule of up to 200 characters, such as rage bait, or a free keyword rule. It works on 11 sites out of the box, among them Reddit, YouTube and X, and finds the items on other sites itself. PureFeed classifies up to 500 posts per day for free and costs $4.99 a month for Pro. Smart Filter gives up to 10,000 credits to start, then plans from $5 a month. Facts about PureFeed were checked on 13 October 2026.

Which one fits
PureFeed is the better pick if
You want ready-made scores to tune rather than rules to write, LinkedIn out of the box, or a summary of your feed.
Smart Filter is the better pick if
You know what you want gone and would rather say it, such as election news or spoilers for one show, want free keyword rules, or want it on sites beyond the big four.
Examples of rules on each site: the Reddit filter, YouTube filter and Twitter / X filter pages.
