Use Join-In Pro together with Grid 3 to access mainstream apps while continuing to communicate with your familiar AAC system.
Whether you use text-based or symbol-based communication, Join-In Pro integrates with Grid 3 to support messaging, searching, writing, browsing, AI tools, and more — using the access method and communication system you already know.
Note: If you already use the original Join-In for Grid 3, you can continue using it alongside Join-In Pro on the same device. This allows you to start using Join-In Pro while keeping the Grid 3 pages and workflows you already know, making it easy to transition at your own pace.
