About

Sentient Studio

Features
Read full description

Sentient Studio makes easy read documents: Stories and Social Narratives, Step-by-Step Guides, Visual Schedules (including Now & Next and First-Then boards), One-Page Profiles, Choice Boards, and Information Pages. If you support someone with a learning disability, autism, or additional needs, this is built for you. Everything stays on your device. No account, no cloud, nothing sent anywhere. You add your own photos, write in plain language, and export a document you can print or share. The app checks your writing as you go. It shows a reading age for whatever you've typed and can simplify a sentence in one tap, cutting jargon, passive voice, and idioms that don't translate well for a literal reader. Exports are properly laid out, not just text dumped onto a page. Pick your paper size, adjust text size, choose a real dyslexia-friendly font if you need one, and control how much fits on a printed page. Every document type and every template is free from the moment you open the app. No sign-up, no subscription, no paywall.
