The smartest keyboard
ever built.

The most personal AI ever built into a keyboard. Rev analyses 12 dimensions of how you write — message length, sentence structure, warmth, humour frequency, emoji usage, energy level, directness, reaction time, punctuation habits, vocabulary range, topic patterns, and emotional baseline. After 200 messages, Rev does not just predict what you might say. It knows what you would say. Calibration is entirely on-device. Your writing patterns never leave your phone.

Draw continuous paths across the keyboard to form words. Rev's swipe engine handles 18 languages including Latin, Cyrillic, and Greek scripts. A gradient purple trail follows your finger. Word prediction combines on-device ML with your personal vocabulary built from actual usage. The engine corrects misaligned swipes in real time using a custom Bezier path interpolation algorithm.

As you type, Rev predicts your next word, phrase, or even full sentence and displays it in faded text ahead of your cursor. Press Tab to accept instantly. The ghost engine combines a trigram language model with your personal writing patterns. Over time it learns your specific phrases, shortcuts, and signature expressions.

Tap the Rev spiral to generate a reply to any message. Paste what someone sent you or type a description. Choose from 5 tones: Playful, Gentle, Professional, Casual, or Spicy. Rev generates 3 variations per tone, all written in your calibrated voice. Swipe through the cards, tap to send, or ask Rev to refine any suggestion with a follow-up prompt.

Translate any text you are about to send without leaving the keyboard. 36 languages supported. Tone, punctuation, and emoji are preserved in translation where linguistically appropriate. Long-press the globe icon to access the translation panel. The original and translation are displayed side by side before you send.

Six correction layers working in sequence: contraction expansion, Levenshtein distance correction, undo-last correction, flash mid-word correction, personal dictionary overrides, and contextual disambiguation. The system learns your deliberate non-standard spellings and stops correcting them. You can add words to your personal dictionary by long-pressing any underlined word.

Long-press any AI-generated reply to schedule it. Options include Send in 1 hour, Send tonight at 9pm, Send tomorrow morning at 8am, or custom time. Scheduled messages are stored on-device and sent when the time arrives, even if the app is in the background. A badge shows the number of pending scheduled messages.

Before you send a message that Rev detects as aggressive, passive-aggressive, sarcastic, or potentially hurtful, a subtle warning appears. Rev does not block you — it simply asks if you are sure. You can dismiss, soften with one tap, or send as-is. The emotional tone model runs entirely on-device.

A searchable panel of your 30 most recently copied items appears with a single tap. Items are categorised: links, phone numbers, addresses, and text. Pin important items to keep them at the top. The panel persists across app switches and is available immediately without leaving the keyboard.

Rev detects which app you are currently typing in and adjusts its suggestions automatically. Tinder gets warmer, more playful suggestions. Slack gets concise, professional ones. Gmail gets structured, formal language. The detection uses the app package identifier and requires no configuration.
