iSureType is in Apple TestFlight

iSureType, our flagship iOS keyboard, is live on Apple TestFlight. The early test group is open — sign up at isuretype.com to receive a build.

If TestFlight is new to you: it's Apple's official beta-testing platform. You install Apple's free TestFlight app from the App Store, accept an invite, and the build runs on your iPhone with the same sandboxing and review baseline that App Store builds use.

What's in this build

iSureType is a system-wide iOS keyboard built around T9-style disambiguation, on-device learning, and a few features we haven't seen elsewhere on a keyboard:

• Predictive typing. T9 disambiguation plus contextual suggestions cut the keystrokes per word. In QWERTY mode the literal typing always rides as the first chip, so spelling stays one tap away.
• T9 callouts. Long-press a key, slide to pick the primary or secondary letter for that tuple.
• Smart phrases. Saved-phrase insertion in a single tap.
• Custom autocorrect. Define text-replacement shortcuts (e.g. omw → "On my way!").
• On-device OCR. Apple Vision powers Text and Document modes; on iOS 26+ the wizard upgrades to RecognizeDocumentsRequest so paragraphs, lists, and tables come out as GitHub-flavoured Markdown — exportable to Files, iCloud Drive, or any document provider, with scans able to continue in the background.
• Per-tab Siri shortcuts. "Learn new word" on My Words, "Learn new phrase" on My Phrases, "Scan this" / "OCR" / "Extract text" on the OCR tab. Every shortcut has alternates so iOS suggests the right one however you ask.
• Omnibus profiles + custom tab order. Preferences, custom words, smart phrases, autocorrect pairs, and tab order all auto-save into the active profile. Drag the bottom tabs into any order — restored on profile switch.
• iOS 26 Liquid Glass widgets. A Clipboard widget surfacing your most recent captures with per-row pin / star / delete and a source-app badge; a Scan widget exposing all three OCR modes (Text / Document / Business Card) on one tile in three sizes.
• 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 — no telemetry SDKs.

How to join

1. Visit isuretype.com and tap Join Early Test Group.
2. Accept Apple's TestFlight Terms of Service — beta testing is governed by them.
3. Install Apple's TestFlight app from the App Store, then open the invite on a device running iOS 18 or later (iOS 26 unlocks the document-mode OCR upgrade and the Liquid Glass widgets).

What we'd love feedback on

• T9 callouts. How the long-press → slide-to-secondary feels in your hand at speed.
• OCR accuracy. Real-world signs, receipts, screenshots, and multi-column documents.
• Suggestion ranking. When chip 0 (the literal typing) is what you wanted vs. when one of the predictions wins.

Builds will roll forward as we ship. The "What to test" notes in TestFlight call out what's new each cycle.
