Brotto

Brotto is an AI browser agent that drives the Chrome tab you are already logged into. Most browser agents run on remote headless instances. They hit sign-in walls, fail CAPTCHAs, and burn through model tokens taking raw screenshots. Brotto executes directly in your active browser session via Chrome DevTools Protocol—inheriting your cookies, SSO, and multi-factor authentication automatically. ━━━━━━━━━━━━━━━━━━━━━ KEY CAPABILITIES ━━━━━━━━━━━━━━━━━━━━━ • Authenticated Automation: Run workflows across authenticated tabs—inboxes, internal portals, and dashboards—without handing over your master credentials. • Semantic Grounding: Reads the browser’s Accessibility (AX) tree rather than sending raw screenshots to vision models. Cheaper, faster, and structurally accurate. • Bring Your Own Key (BYOK): Connect your own provider keys. • In-Memory Key Security: Your API keys are held strictly in temporary session memory and are never written to disk by the extension. • Human-in-the-Loop Approvals: Secure mode alerts you with explicit approval prompts before executing sensitive actions, payments, or leaving trusted domains. • Complete Local Visibility: Step counts, context usage, and full observation audit trails remain accessible directly in your side panel. ━━━━━━━━━━━━━━━━━━━━━ WHAT BROTTO DOES NOT DO ━━━━━━━━━━━━━━━━━━━━━ ✕ Never stores your credentials or API keys on external server disks. ✕ Never executes downloaded arbitrary code or remote evals. ✕ Never sends unprompted ambient page data without explicit configuration. ━━━━━━━━━━━━━━━━━━━━━ REQUIREMENTS & SETUP ━━━━━━━━━━━━━━━━━━━━━ 1. Chromium-based browser. 2. A connected Brotto orchestrator (self-hosted or cloud). 3. An active model provider API key.
