Fihrist Lab by Glidd.io

Fihrist Lab — local-first KDP niche research directly inside Amazon, separating real market signals from noisy result counts.

Fihrist Lab works directly inside supported Amazon marketplaces to separate meaningful signals from ads, duplicates and off-topic listings. It models demand as a range, verifies organic keyword rankings, surfaces recurring complaints, tracks market movement and keeps your research in your browser. CORE TOOLS • Niche Ledger: X-ray any niche to reveal its hidden anatomy—the real competitors, organic vs. sponsored listings, format mix, categories, and the books shaping the niche. • Niche Analyzer: Powered by a carefully engineered algorithm built to get as close as possible to real Amazon search demand, delivering the best possible monthly estimate as a credible range—not a misleading single number. • Keyword Lab: Built to uncover high-intent, book-focused long-tail keywords directly from Amazon, helping you discover the phrases real shoppers are already searching for. • Keyword Spy: Reveals the keywords a competing book genuinely ranks for organically on page one—while filtering out sponsored placements that create a false picture of its visibility. • Opportunity Gap: Exposes where competing books disappoint readers, then turns those hidden weaknesses into strategic opportunities designed to help your book stand out and outrank them. • Category Analyzer: Maps the categories and ranking positions Amazon assigns to a niche or competing book, helping you uncover where the market is concentrated and where easier opportunities may exist. • The Tracker: Monitors daily movement across BSR, estimated sales, price, revenue and category position, giving you a clearer view of how a book or niche is performing over time. • Promo-Aware Pricing: Detects the real price currently shown to shoppers, identifies genuine promotions and prevents temporary discounts from distorting revenue estimates. • The Vault: Keeps your most valuable niche research organized locally, so you can revisit opportunities, compare markets and export your tracking data whenever needed. • Trademark™ Check: Screens title phrases against live USPTO results and publishing-risk signals, helping you identify potentially dangerous terms before they put your book—or your account—at risk. It is a research safeguard, not legal clearance. WHY FIHRIST LAB • One-time purchase; no monthly subscription• Research data stays in your browser• Local relevance analysis• Honest ranges instead of fake precision• Designed for serious KDP publishing decisions• If it saves you from one bad niche, it already paid for itself. IMPORTANT NOTES Fihrist Lab is a research instrument. It does not guarantee rankings, sales, revenue or legal clearance. Amazon does not publish exact search volume, so demand is modeled from observable signals and displayed as a range. Some live checks depend on data rendered by Amazon or USPTO and may change when those sites change. Google Chrome 109 or later is required.
