Brotto

Let you ask an AI to perform tasks in your own logged-in browser. Bring your own model key.

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.
