Jonathan Huang, Partner at BITKRAFT Ventures, said Acti is well-positioned to shape the next generation of human-computer interaction. He added that the company is rethinking how people interact with apps and building a platform that could become essential for future AI agents.

Young Wang, Founder and CEO of Acti, said today's AI agents are limited because user data is scattered across different apps. He said Acti solves this by creating a shared context layer across apps, giving AI a better understanding of users without being tied to a single platform.

In a statement on Tuesday, Acti said its AI-powered keyboard acts as a smart assistant that works across all the apps a user opens. The company will use the new funding to hire more engineers and AI talent, improve its on-device AI, and expand its Skills ecosystem and developer community.

Acti aims to build a secure, on-device AI assistant that learns a user's habits, favorite apps, and everyday tasks over time. All this information stays on the user's device, giving them full control over their data instead of storing it on a single platform.

Unlike traditional AI apps that require users to switch between applications and repeatedly provide context, Acti brings AI directly into the keyboard. Users can assign custom functions, called Skill Keys, to any key—for example, translating a message or instantly sharing a meeting link with a long press—without needing to write any code.

Users can also create new Skills simply by describing what they want through Acti's Skill Builder. According to the company, early users created more than 1,000 custom Skills within the first two weeks.
