iSureType

A T9-derived iOS keyboard that adapts to how you actually type. Predictive without being noisy. Customisable haptics, gestures, and corrections — all in a system extension currently distributed through Apple TestFlight. It is one of the on-device-ML accelerators a PenDraco engagement can draw on.

What it does

• T9-style disambiguation. Type a word as a single tap-pattern; the engine ranks the right candidate inline.
• On-device adaptation. The model learns from your corrections — no cloud round-trips, no telemetry SDKs.
• System-wide. Works in any app: iMessage, Mail, browser fields, third-party clients.
• Privacy-first. All learning is on-device. The keyboard's only network surface is App Group sync between the host app and the keyboard extension.
