Operator.io

Operator.io runs a personal AI agent that works on its own schedule. It is built on OpenClaw, the open source agent framework, and hosted so there is nothing to install and no server to keep alive. You sign in and the agent is already running with web search, a real browser, and persistent memory attached. The agent does the work you would otherwise do across a browser and a terminal. Ask it to research a company or a topic and it reads across the open web, including the sites that expose no public API, then comes back with the sources behind its answer. It drafts and sends email and SMS in your voice, handles the routine traffic on its own, and pulls you in when something needs a decision. Point it at a competitor's pricing page, a subreddit, or an earnings calendar and it checks on a schedule and messages you the moment something moves. On the developer side it manages code through GitHub, ships deploys through Vercel, queries your databases, and runs your social accounts across Instagram, TikTok, X, YouTube, LinkedIn, Reddit, and more. You reach it from Telegram or Discord, the same way you would message a colleague. Hand off a task, ask it to dig into something, or check on a job you set running earlier, and it replies in the same thread. It also reaches out on its own when a scheduled job has something worth telling you, so a morning brief or a weekly report lands without you remembering to ask for it. Every instruction, decision, and preference gets written to memory, so the agent builds real context about you and your work over months and you stop repeating yourself. Each agent runs in its own isolated environment with its own files and browser sessions, and credentials are encrypted at rest and never shown again in the dashboard after setup. Because the agent underneath is unmodified OpenClaw, your skills, identity files, and configuration stay portable, so if you ever want to move to your own server you can take your setup with you. Plans start at $20 a month and bundle the model, web search, and media generation into one invoice, with no separate bill from the model providers. Operator.io is backed by Y Combinator.
