Asterics AAC review
A flexible free AAC option for users needing personalized grids and varied input methods.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Asterics AAC is a web-based augmentative and alternative communication tool for people who need supported communication. It is designed for users, families, educators and care teams who need adaptable communication grids rather than a fixed symbol layout. Grids can combine symbols, images, text, keyboards and speech actions, while input can come through touch, mouse, keyboard, scanning, hovering, microphone input, external switches or AsTeRICS Framework events such as eye or head movement. The product is also referred to as AsTeRICS Grid in vendor documentation.
Its strongest fit is breadth of access and customization. Layouts, images, text and grid elements can be edited, with both symbol-based and text-based communication supported. Text-to-speech actions can speak labels or custom text, while self-learning dictionaries and word prediction support text entry. Multilingual grid sets and content languages widen its use across communication needs. Offline operation is available after the initial application load, and the browser-based approach covers Android, iOS, Windows, macOS and Linux. Optional environmental and computer control adds scope for users whose communication setup extends beyond speech output.
Asterics AAC is free and open source, with no paid tiers described in the published product details. Its ecosystem includes the AsTeRICS Framework, ARASAAC API, Matrix messenger and YouTube. That combination suits buyers who value control over layouts, languages, access methods and content without software licensing costs. It may be less suitable for someone seeking a ready-made grid with minimal configuration, since the product’s value depends on tailoring layouts and actions. Users considering environmental or computer control should also be comfortable with the relevant AsTeRICS Framework event support and setup requirements.
