CLARA

Core Logic And Reasoning Assistant · Hacktoberfest Mannheim × Q-Summit 2026

CLARA is a Chrome extension that opens the web to blind, low-vision, deaf and hard-of-hearing people. Talk to her and she opens the page or YouTube video for you, reads it aloud in her own voice, captions videos live, describes images, fixes low-contrast text, rewrites hard text in plain language, and fingerspells names in ASL. Built with Gemma 4 and ElevenLabs.

Open CLARA Live: nothing to install →

Or install the Chrome extension

Download the CLARA extension (.zip) and unzip it.
Open chrome://extensions, turn on Developer mode (top right), click Load unpacked and pick the unzipped folder.
Click the CLARA icon in the toolbar. The side panel opens, already connected.
Press Talk to CLARA (or Alt+Shift+C) and say “open mlh dot com” or “play Hacktoberfest on YouTube”. The first time, Chrome asks for the microphone in a new tab.

Test pages

Control page: built to fail accessibility checks (unlabeled images, low contrast, legal text, names to fingerspell).
Actual site: mlh.com, opened with the extension on.
