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.
