What It Is

Glaaster is an AI document adaptation platform for people with dyslexia and learning difficulties. It mainly serves DYS users, students, families, disability officers, educational institutions, and speech therapists. Users can upload courses, books, or any text, or scan printed materials with a mobile phone. The platform then converts them into versions that are easier to read and review.

Core Capabilities

Its focus is not general-purpose chat, but accessibility enhancements around “reading, understanding, and reviewing.” Users can adjust visual parameters such as font, font size, line spacing, letter spacing, and colors. It supports formats including PDF, Word, PowerPoint, and OpenOffice. It also offers text-to-speech in 5 languages, complex sentence rewriting, word-meaning explanations, exercise hints, and Q&A with an AI teaching assistant. For revision, documents can be turned into podcasts, QCM multiple-choice questions, and flashcards with one click. The page explicitly states that flashcards are based only on the original text and are not invented by AI.

Pricing and Trial

The free plan is fairly appealing: visual document adaptation is unlimited, while advanced features such as speech synthesis, rewriting, the AI assistant, flashcards, and quizzes can process 1 document per day. New accounts automatically receive a 7-day full-feature trial, with no bank card required. However, the main page does not disclose the standard subscription price, so you still need to check the subscription page to assess long-term costs.

Data, Quality, and Limitations

In terms of credibility, Glaaster says it works with the Lyon Neuroscience Research Center and the Laboratory for Cognitive Mechanisms, and its calibration test recommends suitable reading settings. Its privacy statement is also relatively clear: documents are encrypted, hosted by OVH in France, stored in the user’s personal account, and not used to train Glaaster’s or its partners’ models. The limitations are that its dyslexia risk test cannot replace a medical diagnosis; the tool can only supplement speech therapy and human support; and the adaptations apply only to documents inside the platform, not to the entire computer or other websites.

Who It’s For and Access from China

It is especially suitable for learners with dyslexia, dyspraxia, TDA/H, low vision, or stress when reading in a foreign language, as well as schools and training organizations that need to improve course accessibility at scale. For users in China, the main page does not specify whether it supports a Chinese interface, Chinese OCR, Chinese text-to-speech, or local payment methods, and mainland China network accessibility cannot be determined, so china_access can only be marked as unknown. If Chinese-language support is essential, you should test it with the free trial first.
