What's New

Current build v1776623871372

iSureType is built around two non-negotiables: privacy by construction and functionality first. Image Description, the T9 engine, spell recovery, and every other recognition path all run on-device using Apple's Neural Engine. Nothing is synced to a server; nothing is sold.

Privacy by construction

Every recognition path — Image Description's Vision ensemble, OCR, NLTagger smoothing, UITextChecker spell recovery — runs on-device using Apple’s Neural Engine frameworks. Photos, typed text, and clipboard entries never leave your phone unless you explicitly share them.

Functionality first

No in-app purchases, no ads, no account. Every feature on this page works offline. The marketing site you’re reading now is itself a PWA — installable and cache-backed so the authoring workbench and template library stay usable without a connection.

Version milestones

A user-facing summary of what shipped when.

  1. v0.6.x Beta

    Omnibus profiles, Image Description, voice shortcuts

    • UITextChecker spelling recovery on every T9 buffer — the intended word still surfaces even when a stray tap clips a neighbouring key.
    • Image Description wizard — pick a photo, review the sentence on step 4, commit to the clipboard, jump to the Clipboard tab. The full Vision ensemble (classifier, OCR, faces, humans, animals, barcodes) + NLTagger smoothing runs entirely on-device.
    • Omnibus profile files — your words, phrases, autocorrect pairs, and tab order travel with a profile snapshot.
    • Import / Export tab owns `.profile.isuretype` / `.phrases.isuretype` / `.words.isuretype` as first-class document types with SHA-256 integrity reporting on every side.
    • Siri voice shortcuts — Add a Word, Save a Phrase, Save to Clipboard, Describe This.
  2. v0.5.x Shipped

    QWERTY layout, live-sync settings, tab reorder

    • Optional QWERTY letter layer alongside the SureType T9 layer. In QWERTY the exact typed string always rides as chip 0.
    • Host-app Settings and the keyboard extension’s tray toggle stay in lockstep in real time via a shared `UserDefaults` observer.
    • Drag-to-reorder the bottom-bar tabs; layout restores on profile switch.
  3. v0.4.x Shipped

    Profiles, Smart Phrases, Custom Words

    • Named profile bundles — save every preference; cycle favourites from the chin bar.
    • Smart Phrases: categorised, bolt-button insertion, per-category accent colour.
    • Custom Words: categorised vocabulary that seeds the T9 suggestion engine.
    • Autocorrect: user-defined replacement pairs (`omw → On my way`).
  4. v0.3.x Shipped

    T9 callouts, haptics, emoji grid

    • T9 long-press callout with thumb-offset positioning + squiggly connector line.
    • Unified haptic-intensity slider (Off / Light / Medium / Heavy) replaces per-event toggles.
    • Dedicated emoji grid with skin-tone modifier picker — no Apple long-press required.
  5. v0.1 – 0.2 Early preview

    Core keyboard + suggestion engine

    • SureType 14-tuple letter layer with ambiguous-T9 DFS disambiguation.
    • Contextual suggestion pipeline on a background queue; inline composition preview in the host field.
    • App Group – shared settings so the keyboard extension and host app stay on the same snapshot.
