Add items in seconds, then connect your inventory to ChatGPT, Claude, or any AI assistant — so you can simply ask "what do I have?" instead of digging through lists.

Find it fast Powerful search and browse let you locate any item instantly. Tap through to full details whenever you need them. Built for control • Camera-first capture with smart auto-fill • Fast, full-text search across your whole inventory • Bring your own LLM API key • Configurable backend and secure token storage • Clean, native iOS design Whether you're tracking household belongings, small-business stock, gear, or a growing collection, this is the inventory that's ready to work with AI — not just sit there.
