Algorithm Mirror

How Algorithm Mirror works

Shown
Posts and videos that actually appeared on your screen while you browsed your feeds. The extension notes them as you scroll, including Shorts and Reels you swipe through. Time on screen is capped at 60 seconds per item.
Engaged
Posts you liked or saved. Each post counts once, even if you like and save it. On YouTube, videos from your watch history are counted separately as Watched.
Mismatches
Topics where what the feed shows you and what you engage with don't line up, for example a topic that fills a big share of your feed but rarely gets a like from you.
More data needed
Comparisons only appear once there's enough to go on: at least 10 shown posts and 10 engaged posts on a platform. Until then, keep browsing normally.
AI topic labels
An AI model reads each post's text and assigns it a topic and tone. This runs every 15 minutes, so brand-new posts may show as unlabeled for a few minutes. Labels are usually right but can be wrong on short or ambiguous posts.

Your algorithm, explained

Written by AI from your numbers only (topic shares and counts, never your posts). It can get things wrong, so check it against your charts.
