Uniboard AI keyboard for Android runs fully on your phone

Uniboard, a new Android keyboard from Wizonlab, corrects typos and answers queries on the phone's own chip, so what you type doesn't have to visit a cloud server.

Your keyboard sees everything you type first: messages, searches, sometimes passwords. Korean company Wizonlab has released Uniboard, an Android AI keyboard that does its smart work on the phone itself instead of sending text to a server.

The company's argument is simple. Some AI keyboards rely on cloud servers for spell correction and sentence suggestions, which means words and sentences travel back and forth, and that data could leak. Uniboard avoids that trip. Its AI runs on the phone's CPU and NPU (the chip block built for AI tasks), so most features also work with no network connection.

How does Uniboard work?

Under the hood is a small language model based on Qwen2.5 0.5B, paired with an offline knowledge cache. Together they handle keyword suggestions, calculations, unit conversion, search, typo correction based on Korean jamo (the letter components of Hangul), on-device knowledge lookup and protection of the user's own vocabulary.

After you finish a sentence, you tap the "SC" key and the keyboard marks what needs fixing. A three-layer output check is meant to catch inappropriate model output and garbled strings. Dialect, abbreviations and new slang are kept as separate vocabulary, so the keyboard corrects them less often by mistake.

Is it safe for passwords and card numbers?

According to the company, the AI switches itself off when it detects a password or credit card field in a website or app form. It also pauses AI processing when the battery runs low or the phone heats up.

Wizonlab's Park Chi-won says the keyboard is where sensitive data enters first, so the goal was to shorten the path data travels. The company plans to follow with a security keyboard for businesses, a meeting-notes assistant and real-time translation, all running on-device. The source does not give a price or a list of supported countries.
