Mac

Your Mac has been asleep for 40 years. Index is the awakening. Finder searches filenames. Index searches meaning. Ask questions in plain English, get answers from your own documents—powered by AI that runs entirely on your Mac. No cloud. No subscription. No data ever leaves your computer. ▸ SEARCH BY MEANING, NOT FILENAMES Stop trying to remember where you saved things. Just ask: • "What did I write about the Paris meeting?" • "Show me recipes with chicken" • "Find my notes on quantum computing" Index understands context. It finds relevant documents even when your exact words don't appear in them. ▸ AI ANSWERS FROM YOUR FILES Hit Enter on any search and Index synthesizes an answer using a 4-billion-parameter language model running locally on your Apple Silicon chip. Ask complex questions that span multiple documents—Index connects the dots. ▸ 100% OFFLINE. 100% PRIVATE. This is not cloud AI. Index runs entirely on your Mac using Apple's Neural Engine. Turn off Wi-Fi and it works exactly the same. Your documents are never uploaded anywhere. We can't see your files because we never built the infrastructure to see them. Privacy isn't a setting you toggle. It's the architecture. ▸ TURN ANY DOCUMENT INTO A PODCAST Select any text and click Play. Index reads your documents aloud with natural, expressive voices. Transform PDFs into podcasts. Listen to meeting notes during your commute. Your eyes get tired—your ears don't. 10 voices included. Background playback. ▸ WORKS WITH EVERYTHING • PDFs (with OCR for scanned documents) • Word, Excel, PowerPoint • Pages, Numbers, Keynote • Plain text, Markdown, RTF • Source code (50+ languages) • HTML, XML, JSON • And more... ▸ BLAZING FAST Semantic search in under 50ms, even with 10,000+ documents. The AI responds in 2-4 seconds. Built from the ground up for Apple Silicon performance. No subscription. No monthly fees.
