Acco - Your Accessibility CoPilot

Acco is a voice-first web safety agent that acts as a guardian for blind and visually impaired users browsing the internet. Users speak a goal like "Pay my electricity bill" and Acco navigates a real cloud browser, detects scams and risky pages in real-time, and guides users with expressive voice — adjusting tone, speed, and urgency based on what it sees. It features a dual-stage risk analysis pipeline (fast Haiku check + deep Sonnet analysis), domain verification to catch brand impersonation, payment confirmation gates with amount readback, and natural conversational voice responses powered by Cartesia Sonic. The agent runs on Browserbase with Stagehand for live browser automation, Claude for reasoning, and supports both push-to-talk and Cartesia Line for real-time streaming voice interaction.
