Asterics AAC
Free, open-source desktop AAC app for building offline communication grids with touch, eye gaze, and switch input.
Asterics AAC is the pick when the budget is zero and the device is a desktop. It is free and open source, runs offline on Windows, Linux, and macOS, and covers the input methods that matter clinically: touch, eye gaze, and switch scanning. The multilingual symbol dictionaries and the separate user-management area of the web editor are exactly what a therapist juggling several clients needs, and driving a media player or smart home device from the same grid is a real independence feature many paid rivals do not ship. Where it loses is mobility: plan on a fixed machine in a classroom, clinic, or home rather than a phone in a pocket. If you need commercial onboarding, look at Proloquo2Go or

Skip Asterics AAC if the person communicates on a tablet or phone, or if you need two therapists editing the same board at the same time — this is a fixed desktop install.
Eye gaze access is not included: you buy and configure the third-party eye tracker yourself, and that hardware typically costs more than the software ever would.
Asterics AAC is free and open source, which puts it below every commercial desktop AAC app you would otherwise quote — Proloquo2Go and TouchChat both carry per-license costs. It fits schools, small clinics, and families spending nothing on software. The cost you actually carry is hardware (a machine plus any eye tracker) and staff time to learn the browser-based editor.

What is Asterics AAC?
Asterics AAC — Free, open-source desktop AAC app for building offline communication grids with touch, eye gaze, and switch input. Best for Individuals with speech impairments who use a desktop, offline AAC setup, Speech therapists building and maintaining custom boards for multiple clients, Special education classrooms with fixed Windows, Linux, or macOS workstations. Free to use.
Asterics AAC is a free, open-source augmentative and alternative communication (AAC) application for people with speech and language impairments. You install it as a desktop app on Windows, Linux, or macOS, and you build and maintain boards through a web-based grid editor at grid.asterics.eu — either by logging in or by working as an offline user. The editor separates the work into distinct areas: a main view, grid management, dictionary management, user management, settings, help, and an about page, so one board library can serve several communicators. Because the grids and symbol dictionaries live on your machine, communication keeps working when there is no internet connection. Input is not limited to a touchscreen: the app supports touch, eye gaze, and switch scanning, so people with very different motor abilities can use the same board. Boards are assembled from symbols, text, and media, with multilingual symbol dictionaries and text-to-speech output for spoken communication. Beyond talking, Asterics AAC can drive media players and smart home devices from the same grid, so a single interface covers communication plus some everyday environmental control. It is aimed at speech therapists, special educators, and families who need a no-cost, customizable AAC setup they fully control. Compared with commercial apps, there is no license fee, and the trade-off is a desktop-first design rather than a native mobile app.

Our long-form take written Jul 23, 2026 is more than 90 days old, so it is being re-reviewed against current data and is not shown.
Limitations
- Asterics AAC is a desktop application, so there is no native iOS or Android version; plan on a Windows, Linux, or macOS machine rather than a phone or tablet.
- Multi-user support is handled through user profiles and per-user accounts in the web editor rather than real-time collaborative editing, so two people cannot edit the same grid simultaneously.
- Grid creation and editing run through the web interface at grid.asterics.eu, which assumes some comfort with browser-based configuration, and the project's own interface text is translated through a language layer.
- Eye gaze use depends on third-party hardware that you provide and configure separately.
- Because the project is open source rather than commercially licensed, you should not expect the support and onboarding rhythm of a paid vendor.

GeneratedReal-world workflow fit
Concrete scenarios for the personas Asterics AAC actually fits — and what changes day-one when you adopt it.
You install the desktop app on the clinic workstation, log into grid.asterics.eu, and create a separate user profile for each client under user management. Each client gets a board built from the multilingual symbol dictionary, with cell sizes set to match their access method.
Outcome: Several clients share one machine and switch between their own boards without reinstalling anything, and boards keep working if the clinic network drops.
You build a grid with switch scanning enabled, so the child moves through cells with one accessible button and triggers text-to-speech to speak. You keep a second row of cells for the media player and a lamp.
Outcome: The child communicates and controls the room from the same board with one button, on a home computer that does not need an internet connection.
You set up a Windows workstation as a shared AAC station, add offline users for each student in the editor, and build a core vocabulary board plus a media control grid students can reach from the main view.
Outcome: Students rotate onto the same machine and pick up their own boards, and lesson-time communication continues even when the school Wi-Fi is unreliable.
Use cases
- Build a personalized communication board for a child's daily routines
- Control lights and appliances from the same grid used for speech
- Let a switch user navigate boards with a single accessible button
- Swap between two languages on one communication board
- Run several clients' boards from one clinic workstation using user profiles
- Keep communication working in classrooms or homes with no reliable internet
- Start music or video from a media control grid
- Set up a shared AAC installation in a special education classroom
Setup time & first value
How long it actually takes to get something useful out of Asterics AAC — broken out by persona, not the marketing-page minute.
Speech therapist: roughly an hour to install the desktop app, create client profiles, and build a first board in the grid editor; reuse of shared dictionaries speeds up each additional client. Parent or caregiver: 30–60 minutes to a working first board with text-to-speech. Classroom: budget a couple of hours for the shared workstation plus per-student profiles. Eye gaze adds separate hardware
Switching to or from Asterics AAC
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From paper or printed communication boards: rebuild the vocabulary as grid cells using the multilingual symbol dictionaries, then layer switch scanning or eye gaze on top.
- →From a commercial desktop AAC app: recreate the core vocabulary grid in grid.asterics.eu, set cell sizes to match the user's access method, and add each communicator as a user profile on the shared machine.
- ↗To a tablet-based AAC app: export your vocabulary layout as a reference and rebuild it in the mobile app, since Asterics AAC has no native iOS or Android build to carry across.
- ↗To a commercial vendor-supported AAC suite: reproduce your grids and symbol sets in the new tool and arrange the training and support contract the closed-source product provides.
