Asterics AAC
Free open-source desktop AAC app for offline communication grids.
Asterics AAC is a robust, free AAC tool for desktop users, offering offline grids, eye gaze, switch scanning, and smart home integration. It's a cost-effective alternative to paid options like Proloquo2Go, but it lacks mobile apps and AI predictions. RAC recommends it for budget-conscious families and educators who value customization and privacy. If you need mobile support or advanced word prediction, consider Proloquo2Go or TouchChat instead.

About Asterics AAC
Asterics AAC is a free, open-source augmentative and alternative communication (AAC) application designed for individuals with speech and language impairments. It runs fully offline on Windows, Linux, and macOS, and includes a web-based grid editor at grid.asterics.eu. The app supports multiple input methods: touch, eye gaze, and switch scanning, allowing diverse users to communicate effectively. You can create custom communication grids with symbols, text, and media, and it integrates with smart home devices and media players, enhancing independence. The tool offers multilingual symbol dictionaries, text-to-speech output, and cloud sync for online users. It is ideal for speech therapists, special educators, and families needing a flexible, cost-free AAC solution. Unlike proprietary apps like Proloquo2Go or TouchChat, Asterics AAC is completely free and open-source, giving you full control and privacy. However, it lacks a native mobile app and advanced AI features like predictive text, so it's best suited for users with desktop access who value customization and offline functionality.
Behind the Verdict
Asterics AAC stands out as a genuinely free and open-source AAC solution, a rarity in a market dominated by expensive proprietary apps. Its strengths lie in its offline capability, ensuring communication works without internet, and its multi-input support, including eye gaze and switch scanning, which are critical for users with severe motor impairments. The integration with smart home devices and media players is another differentiator, letting users control their environment directly from their communication grid. The web-based grid editor is powerful for creating custom boards, and cloud sync allows for sharing across devices. However, Asterics AAC is not without limitations. The absence of a native mobile app is a significant gap, as many users rely on tablets or phones for AAC. There's no AI-powered predictive text or word suggestion, which some users may find helpful. Real-time collaboration is also missing; sharing is limited to cloud sync. Additionally, the interface can feel dated and less polished compared to commercial alternatives, and the learning curve for setting up grids may be steep for non-technical caregivers. Overall, Asterics AAC is an excellent choice for desktop-centric users, especially in educational or therapeutic settings where budget constraints are tight. It's also a great option for tech-savvy individuals who want full control over their AAC system. For those needing a mobile-first experience or advanced AI features, other tools may be more suitable.

Real-world workflow fit
Concrete scenarios for the personas Asterics AAC actually fits — and what changes day-one when you adopt it.
A speech therapist needs to create a custom communication grid for a child with autism.
Outcome: The therapist uses the web-based grid editor to build a grid with symbols and text, then syncs it to the child's Windows laptop. The child uses touch input to communicate during sessions, and the therapist can easily update the grid remotely.
A teacher has a student with limited motor control who uses switch scanning.
Outcome: The teacher sets up Asterics AAC on a classroom desktop, configures switch scanning, and integrates a media player so the student can select music as a reward. The student uses a single switch to navigate and activate buttons.
A caregiver helps an adult with ALS control home appliances using eye gaze.
Outcome: The caregiver sets up Asterics AAC on a laptop with an eye tracker, adds smart home integration, and the user can turn lights on/off and adjust the thermostat by looking at grid items, increasing independence.
Use Cases
- Create personalized communication grids with symbols and text for daily routines.
- Control smart home lights and appliances using AAC grids.
