Upket Keyboard: Gõ tiếng Việt

Upket Keyboard is a lightweight Vietnamese keyboard that uses Telex or VNI typing, running entirely on your computer: the application has no internet access and does not collect your typing data.

NATURAL VIETNAMESE TYPING
• Telex and VNI: Type accents in any order (nguoiwf → người), repeat to remove accents, use 'z' to delete accents

• Choose new accent styles (hoà, thủy) or old ones

• Automatically restore English words when you type the wrong accent, use '⌫' to retrieve them

• Telex fast typing: f → ph, j → gi, w → qu; g → ng, h → nh, k → ch
• Swipe the Space key to switch between Vietnamese and English, remember the language for each application
• Automatically capitalize the first letter of a sentence, automatically add a space after punctuation marks, double Space for a period
• Password, email, and phone number fields automatically disable Telex input; Number pad opens the numeric keypad with large keys

SMART SUGGESTIONS
• Suggests words in Vietnamese and English, learn words you use often (saved only on the device)
• Spell check suggestions directly on the suggestion bar, clear typing correction
• Vietnamese spell checker for all applications
• Swipe to type (glide): Vietnamese text without accents, keyboard automatically adds accents
• Shortcuts: ko → không, mn → mọi người, add your own shortcuts

• Personal dictionary for proper names and terms

Android displays a general warning for all third-party keyboards when you turn on the keyboard. Upket Keyboard has no network permissions, so it cannot send your typed content anywhere.

Voice input uses the computer's speech recognition service (usually Google's) and only requires microphone permission.
