Otto — your browser, on autopilot. An AI side-panel assistant that reads pages, clicks, and types for you. Your key, no server. Otto is a side-panel assistant that operates your real, logged-in browser on your instruction. Ask it to do something "summarize this page", "open my analytics and tell me how traffic is", or "find the cheapest option across my open tabs". It navigates, reads pages, clicks, types, and takes screenshots on its own, then reports back in chat. You can stop it at any moment. Chrome shows a visible banner whenever Otto controls a tab. Bring your own AI: Otto connects directly from your browser to the AI provider you choose using your own API key. There is no Otto server, account, subscription, analytics, or data collection by the developer. Your key is stored only in Chrome's local extension storage and sent only to the provider you picked. Note: Otto requires an API key from a supported AI provider (pay-per-token; some providers have free tiers). A consumer chatbot subscription does not include API access. The full list of supported providers is in the README on GitHub. Otto is fully open source: https://github.com/legisus/otto-ai-sidebar
