The difference
Reddit's voting system surfaces consensus and popularity.
FIFI surfaces activity, contention, and where the real conversation actually concentrated.
What FIFI surfaces
A Chrome extension that reads the full comment tree — not just what Reddit renders — and tells you where it actually happened.
You opened a 4,000 comment thread. The exchange worth reading had 3 upvotes and was buried deep in the replies. FIFI found it in seconds. Click any result to jump straight there.
You read the whole thread. Except you didn't. Reddit showed you 12% of it. FIFI shows you exactly what percentage of the total comment tree actually reached your screen.
This thread has 847 comments. Reddit loaded 94. The other 753 exist — real exchanges, real activity — and never appeared on your screen. FIFI shows you the count Reddit never does.
Before you read a word — you already know if this thread is a pile-on, a debate, or a dead end. Deep Chain. Fragmented Burst. Wide & Contested. One label. Eight possible shapes.
Two people went back and forth 23 times. Nobody else saw it. FIFI traces the single most active reply path and renders the whole conversation inside the overlay.
You can see 25 threads. One of them is actually worth your time. FIFI scores every thread on the feed before you open any of them — so you know which one to click.
You found an interesting thread 3 hours ago. Since then, 47 new exchanges appeared. FIFI tells you — without you going back to check. A badge on your toolbar. Nothing to configure.
Every day, one thread worth your attention — surfaced at the bottom of your overlay. Free users get the highest-traffic thread on Reddit right now. No searching required.
After every analysis, FIFI generates a shareable image card — thread title, top escalation find, FIFI branding. No usernames. Export as PNG and keep it or share it.
The core of what FIFI does
"Reddit shows you what people agreed with. FIFI shows you where the conversation actually happened."
