AccessPortal — make web content more accessible in Chrome

Adaptive web accessibility with Chrome's built-in AI. Private, on-device.

AccessPortal is a companion extension for the AccessPortal progressive web app (PWA). It helps you make web content easier to understand and use by sending page text to the PWA, where Chrome’s built-in AI (Gemini Nano) processes it privately on your device. WHY INSTALL THIS EXTENSION? Many websites are hard to read because of dense language, long articles, or layouts that are not accessible. AccessPortal bridges the page you are reading and a dedicated accessibility workspace in Chrome. You stay in control: nothing is sent until you click the extension and choose what to adapt. HOW IT WORKS Open any article or web page in Chrome. Click the AccessPortal icon to open the floating panel. Choose one of these actions: • Adapt this page — sends the visible text of the current page to the AccessPortal PWA. • Adapt selection — sends only the text you have highlighted. Confirm in the panel when prompted. Switch to the AccessPortal tab and use on-device tools such as key-point summaries, easy-read simplification, translation, image descriptions (Visual profile), or voice-driven notes (Motor profile). All AI processing in the PWA runs locally with Gemini Nano. Your content is not uploaded to AI4Context servers. WHAT THE EXTENSION DOES • Opens or focuses the AccessPortal PWA tab. • Reads visible text or your selection from the active tab after you confirm. • Passes imported text to the PWA so you can summarize, simplify, translate, or continue in other accessibility profiles. • Remembers optional settings (PWA URL, language) in chrome.storage.sync on your Chrome profile. WHAT IT DOES NOT DO • Does not read tabs in the background without your click. • Does not upload page content to developer servers. • Does not autofill forms on external websites. • Does not replace professional accessibility audits or medical/legal advice — always verify important information against the original source. • Chrome-only in v1: requires Chrome’s built-in AI; not supported on Microsoft Edge. REQUIREMENTS • Google Chrome 148 or newer (desktop). • Hardware and browser settings compatible with Chrome built-in AI (Gemini Nano).
