On-device AI
Local speech-to-text and local LLM execution integrated into a real product surface — not a notebook demo. Two distinct AI lanes (transcription on mobile, generation on desktop) running entirely on the user’s hardware.

Platinum AI Notes
A 100% local, no-account AI productivity ecosystem across Android phone, Wear OS watch and Windows desktop. Local voice capture, on-device transcription, a separate Smart Note LLM lane on desktop, private local sync between devices and portable encrypted backup files — designed so the AI runs next to the user’s data, not someone else’s cloud.
The problem
Cloud AI notes apps are not safe enough for real knowledge work.
Most AI note apps ship the user’s most personal material — ideas, meetings, voice recordings — off the device into someone else’s account, behind someone else’s policies, with no real opt-out. Crovyx wanted the opposite: AI assistance that genuinely lives on the user’s own hardware.
- No account, no signup, no cloud profile — the app is usable without ever connecting to a server.
- Voice capture and transcription happen on the device itself.
- Smart Note generation runs through a local LLM on the user’s desktop, not a remote API.
- Sync between phone, watch and desktop is direct and local — not via a vendor backend.
What it does
One ecosystem, three surfaces, zero accounts.
- Android. Native note capture, local voice transcription using on-device speech models, structured storage and search.
- Wear OS. Quick capture from the wrist with the same local-first storage and backup model.
- Windows. Desktop workspace with a separate local Smart Note LLM lane for richer generation tasks.
- Local sync & backup. Direct device-to-device sync with integrity-protected messaging, plus portable backup files for migration and recovery.
Capabilities demonstrated
What this product proves Crovyx can ship.
Cross-device
One coherent product across Android, Wear OS and Windows, with a local sync architecture that doesn’t require an account, a server, or a third party in the loop.
Data ownership
Portable backup format the user controls, integrity-checked sync messages between devices, and a no-account model that makes data ownership a default, not a setting.
If your product needs serious AI but cannot send everything to a third-party cloud — healthcare, legal, internal knowledge, regulated industries, privacy-led consumer apps — Crovyx is built for exactly that kind of local-first system.
