Multion

Multion built its product around a specific bet: that the right interface to a browser agent is your actual browser, with your sessions, your cookies, your logged-in accounts, rather than a sandboxed VM. The Chrome extension lets you describe a task in natural language and watches the agent click through the steps in real time, on the real web, using your own logged-in identity. For everyday personal tasks — finding the cheapest flight on a Tuesday, ordering groceries from the same site you always use, gathering pricing from competitor product pages — that approach is faster and more reliable than spinning up a fresh authenticated session each time. The API is also one of the cleaner ways to embed real browser automation into a custom application.

Where it falls short is the unavoidable fragility of any browser agent right now. Sites change their DOMs, anti-bot defenses get more aggressive, captchas appear, and the agent gets stuck in ways that require human intervention. Multion's reliability has improved noticeably over time but it's still nowhere near "fire and forget" for most tasks. The pricing tier structure also obscures real cost — heavy API usage adds up fast — and the free tier's task quota is consumed quickly during exploration.

Use Multion if you want a browser agent integrated into your real browsing session and you're comfortable supervising it loosely. If you need a developer-grade automation stack with full programmatic control, Browser Use's open-source library gives you that. If you want a polished agentic mode inside a major AI product rather than a separate tool, OpenAI's Operator is the closest analog.
