Content for everyone

Grid 3 is designed with AAC users in mind. There are many readymade resources for everyone to explore, from powerful communication tools for text to grid sets for communicating with symbols and developing literacy.

Symbol communication

A range of vocabularies are available with Grid, from Word Power to PODD and Vocabulary for Life.

Super Core, a new research-based core vocabulary, makes it easier for early AAC users to get started and experience success with symbol communication. Core vocabulary sits alongside activity-specific language, with powerful features that make it simpler to form phrases and communicate meaning.

Smart Grammar features in combination with next-word prediction, make it easier for symbol users to quickly build phrases and clearly communicate meaning.

All popular symbol libraries are included with Grid 3: Widgit, PCS, Symbol Stix and Snap Photos.

Text communication

Text Talker is packed with innovative features to make communicating as fast and efficient as possible. You can quickly generate messages in the moment and prepare for conversations in advance. It also includes ready-made grids for Message Banking, enabling people who still have some speech to capture it and recall it from within the app.

In Fast Talker, apps for everything sit alongside your text communication grid set. Making it easy to switch from sending an email to browsing the web or catching up on your work.

The patented Chat History feature will always suggest phrases based on when you last said something and where you are; using our integrated location aware technology. Included in all of our text communication resources, this ground breaking feature makes communicating with text more efficient than ever before.

Designed for all access

You can use Grid 3 with any type of alternative access, from eye gaze and switch to touch and pointing devices. You can even set it up with multiple access options and switch between them to suit your changing needs throughout the day.

Pointing Device

Any device that acts as a mouse to move the pointer can be used with Grid 3.


If you use touch to control your device Grid 3 has settings to make things easier.

Eye Gaze

Grid 3 can be accessed using a choice of eye gaze cameras.


Scanning with switches in Grid 3 is a new experience, with features that have not been available until now.

Alternatives to scanning, when using more than one switch, include using four switches or a joystick to move up, down, left and right.

Voice Activation

You can also control Grid 3 and activate cells with your voice using our Hey Grid 3 voice activation feature.

Edit and create new resources with ease

Personalising resources is simple, or you can even create your own. Whether you prefer larger text, high contrast colours or larger cells to target – everything is possible! And your profile and content can be backed up and stored safely in the cloud.

Remote editing

Remote editing enables anyone to edit resources and get support, from anywhere in the world. This means that parents and professionals can collaborate on personalising content. Any changes you make are automatically updated, so long as your device is online and Remote Editing is turned on.

Accessible apps

Accessible apps enable you to browse the web, use social media and so much more. There are grid sets for everything from making a quick phone call and sending a quick text or email, to updating your Facebook page and watching videos on YouTube.

Tools for home, school and work

Whether you are just starting out with communication, or using AAC while studying or in the workplace, there are tools to support you through your day-to-day life.  Computer control gives you full access to Windows using eye gaze, pointing devices, or switch.

A voice that belongs to you
