heySaathi is a voice-first agent that operates your phone's screen for you — like Hey Clicky, but 100% on-device, with zero network permission, ever. Built for the 400M+ Indians who own a smartphone but can't confidently navigate it: today they hand their phone, and their UPI PIN, to a shopkeeper, a nephew, a stranger, just to send money or recharge their number. heySaathi replaces that trusted stranger. Say your goal in plain language, and it reads the screen via Android's accessibility tree, plans its next step with Gemma 4 running entirely on-device (LiteRT-LM, no cloud call anywhere), and guides your finger with a spoken, overlay-highlighted walkthrough — or acts itself, with your explicit confirmation. It notices when something goes wrong, an unexpected popup, a relabeled button, and recovers live instead of failing silently. The one constraint everything else serves: your PIN screen is never touched. The moment a secure entry field appears, heySaathi goes hands-off and hands control back to you, by design, not by luck — the app has no INTERNET permission in its manifest at all, provable in ten seconds. That's why this had to be on-device: cloud vision on a payment screen was never an option for the people this is built for. heySaathi is goal-level, not command-level. It doesn't need an app's permission or a pre-built shortcut — it looks at whatever's on screen, the same way a person would, and figures out the steps itself.
