Privacy-first firearm inventory, ammunition tracking, and range planning — plus the first gun marketplace with an AI companion that lists, prices, and manages your collection by voice or chat. One platform, built for the way you actually shoot.
14-day Pro trial · cancel anytime · no charge until it ends
Firearms, ammunition, purchases, and gear — every round accounted for, on-hand counts that stay correct after every range trip.
Range Plan is the part no one else has: plan how much you'll shoot, reserve it against what you own, then reconcile actual vs. planned.
Per-state warnings surface the rules that apply to a listing or a transfer — background checks, magazine limits, rosters, waiting periods.
List from your own inventory and connect with buyers. Rangium never touches payment or the firearm — transfers go through a licensed dealer.

Serial numbers, models, purchase history, and a running on-hand balance per caliber.

Plan rounds, reserve ammo, shoot, then reconcile — the workflow built around how you actually train.

Log every session; inventory and round counts update themselves automatically.

Cost per round, burn rate, and depletion forecasts from your real activity.
Vanta isn't a chatbot bolted on. Ask her in plain English and she reads your real inventory, logs a range session, checks live market value, flags maintenance, and answers caliber and compliance questions — then takes the action for you, on your confirmation.
Generate a real, spinning 3D model from a single photo and set it in a premium black-and-gold card — round counts, sessions, and provenance on the back. Share a private link with friends; your serials and addresses stay yours.

Rangium is the world's first agentic firearm platform. Its built-in AI companion, Vanta, doesn't just answer questions — by voice or chat it takes actions on your confirmation: logs range sessions, deducts ammo, checks live market value, flags maintenance, and lists items in the marketplace. It's the only firearm inventory app and marketplace where an AI does the work for you.
Yes — Rangium is privacy-first. Your inventory and logs are yours, exportable to CSV any time.
No. Rangium is a neutral listings venue — it never processes payment or handles firearms. Every transfer happens in person through a licensed dealer (FFL) where required.
