MergeKey — the first keyboard that hides the keys you don't need. As you type, MergeKey dynamically removes impossible letters and expands the remaining keys, giving you bigger tap targets and fewer typos.

Everything stays on your device. MergeKey never connects to the internet. The only network activity is the App Store handling the optional tips – that's why iOS shows a Mobile Data switch for MergeKey. The optional clipboard keeps your texts on this device only.

MarAI Keyboard

Your keyboard. Your data. Your choice. MarAI is built with one clear principle: what you type is processed on your device and never sent to us. PRIVACY BY DESIGN • Suggestions, corrections and learning run on your device. The keyboard has no server to send your typing to • No ads, no analytics or tracking SDKs, no account • We never sell or share your data • Learned words stay on your device and, with iCloud Sync on, in your private iCloud. We cannot access either • The keyboard keeps the words, word pairs and typing patterns it learns, not your messages MarAI goes online for a few specific things: downloading language packs from iCloud, syncing your learned words to your iCloud, purchases through Apple, web links you share to train the keyboard, and Apple's Translate feature. iCloud Sync is on by default when you are signed in to iCloud, and you can turn it off at any time. INTELLIGENT TYPING • Smart autocorrect: A custom spell-check engine with fuzzy matching catches typos, restores missing diacritics, and keeps the accents you intentionally type, all on your device. • Multi-language support: Over 30 languages with automatic language detection. Switch languages mid-sentence and the keyboard follows along, weighing the words you've taught it. Language packs download from iCloud. • Context-aware suggestions: Word predictions that adapt to what you're typing, including next-word suggestions based on word pairs. • Personal dictionary: The keyboard learns your words and names over time. With iCloud Sync on, they follow you to your other devices. DESIGNED FOR SPEED • Swipe gestures: Swipe left to delete characters or whole words. • Fast period shortcut: Double-tap space to insert a period. • Clipboard history: Your recent copies, one tap away. Kept on this device only, never synced. Unpinned items expire after 24 hours. Content that looks like a password or one-time code is skipped, though the filter can miss things. • Number row: Optional dedicated number row above the keyboard. • Math expressions: Type a simple calculation and see the result in the suggestions. MAKE IT YOURS • Over 20 built-in themes: Five are free, the rest come with Pro. • Adjustable layout: Fine-tune key spacing, padding, and sizing to match your typing style. • Custom theme creator (Pro): Design your own keyboard theme with full color control and live preview. • Custom accent keys (Pro): Choose which accents appear on long-press for each key. YOU STAY IN CONTROL • Private Mode pauses word learning and clipboard capture • Turn iCloud Sync off at any time in the app • Remove any learned word by long-pressing it in the suggestion bar • Clear recent clipboard items whenever you like If you value privacy, transparency, and performance, this keyboard was made for you. MARAI PRO The core keyboard is free, with up to two languages. Pro unlocks the Layout Builder, unlimited languages, Pro and custom themes, custom accent keys and special characters, text snippets, swipe gestures for uppercase, lowercase and accents, statistics, and Date & Time, Translate and AI Writing in the quick action row. AI Writing and Translate use Apple Intelligence and Apple's Translation framework on supported devices. We never receive your text. • MarAI Pro Monthly: auto-renewable subscription, 1 month • MarAI Pro Annual: auto-renewable subscription, 1 year • MarAI Pro Lifetime: one-time purchase, does not renew Prices are shown in the app before purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel them in your App Store account settings.
