FIFI - Reddit Thread Signal & Escalation Analyzer

A clearer view of where Reddit threads intensify.

Reddit shows you what people agreed with. FIFI shows you where the conversation actually happened. Upvotes surface consensus — the most-liked comment floats to the top, and the rest gets buried. With it goes the back-and-forth that actually mattered: the branch that drew 47 replies while the top comment sat at 2, the exchange buried at depth 5, the moment a thread stopped being a discussion and became an argument. FIFI analyzes the full structure of a Reddit comment thread the moment you arrive and surfaces the escalation points worth reading. Click any result to jump straight there, with context. What you see on every thread — free: -Top escalation points — the comment exchanges where the thread's energy concentrated most, ranked by activity. -Invisible Thread — the percentage of the thread's total comments Reddit actually rendered on your screen. Most readers never know how much they're missing. -The Number Nobody Sees — the raw count of comments that exist in the thread but were never loaded. -Thread Fingerprint — the structural shape of the whole thread in one label: Deep Chain, One-Sided Pile-on, Fragmented Burst, Active Surface, or Wide & Contested. Know what kind of thread you're entering before you read a single comment. -Thread Receipt — a shareable image card of your top find. No usernames, no Reddit content. -Subreddit Intelligence preview — score a thread from a subreddit feed before you open it. -Find of the Day — the highest-traffic thread on Reddit right now, at the bottom of your overlay. -Thread Watch (up to 2 threads) — star a thread and FIFI watches it quietly in the background, alerting you when activity meaningfully shifts. Go deeper with Premium — US$4.99/month or US$49/year: -Unlimited escalation points — every buried exchange FIFI found, fully ranked. -Top Exchange — the single most active reply path traced through each branch. -Full Subreddit Intelligence — score every thread on a feed, filter by fingerprint, signal, or comment count, export to CSV. -Auto-analyze controls, advanced filters, and CSV export. -Thread Revisit, Thread Aging, and NEW badges on every thread you've analyzed. -Personal Intensity Benchmark — see where a thread ranks against everything you've ever found. -Thread Watch for up to 20 threads. How FIFI handles your data: FIFI is read-only. It never posts, votes, replies, or touches your Reddit account, and it never connects to your Reddit identity. Thread content is analyzed for structure only and is never stored. See our full Privacy Policy at https://fifiapp.app/privacy. FIFI provides orientation — it shows you where attention, contention, and escalation concentrate, so you can choose where to read more deeply. It doesn't replace reading a thread. It helps you decide what's worth your time.
