Herminox is six free Amazon calculators for sellers and buyers. Everything runs in your browser — no signup, no email gate, inputs never leave your device.
Sellers get FBA profit (2026 fees + fuel), ACoS/TACoS breakeven with max CPC, and inventory recovery: units to get PO cash back after fees.
Buyers get unit price, cost per use, and a return tracker with holiday windows and locked capital.
Coaches can embed widgets. Independent — not affiliated with Amazon. Confirm fees with Seller Central.
VeloTools is a free suite of browser utilities: image compress, PDF tools, invoices, QR codes, background remover, and Focus Room.

Built for people who need real tools without giving up document privacy.
Oneirox reads dreams as sleep-physiology events: REM/NREM context, somatic markers, one mechanism-based analysis. No dream dictionaries, no mysticism — paste what you remember and get a structured neurobiology-first reading.
