Lumey

Lumey runs LLMs entirely on your iPhone. No servers. No logs. No telemetry. Chats, voice notes, and documents you import never leave the device.

Pick from open-weight and proprietary models, side by side. A quick reasoner for everyday questions, a heavier model for code or long-form work; simply switch between them in a tap. Every model runs locally on Apple Silicon.

Bring your own knowledge. Attach PDFs, plain text, or markdown directly to a chat. Lumey chunks and embeds the content on-device, so retrieval happens locally. Install curated knowledge packs for specific domains, or mention them mid-chat to scope a single reply.

Organise your data into multiple vaults. Keep work and personal context separate. Turn on Travel Mode and every vault locks behind Face ID the moment the app backgrounds.

WHAT'S INSIDE • Open-weight and proprietary LLMs running locally on Apple Silicon • Curated knowledge packs that plug into on-device retrieval • Manage multiple vaults to compartmentalize chats, documents, and voice notes • Voice notes transcribed entirely on-device • Travel Mode: biometric lock on backgrounding and vault hiding
