Manus is an autonomous AI agent that takes a task like researching a topic, building a spreadsheet, or writing code, and works through it on its own, browsing the web and running tools as needed, then hands back a finished result. It's less a chatbot and more a virtual assistant you assign work to. It runs on a credit system, so cost tracks how much work each task actually takes rather than a flat seat price.

Toyo is an AI agent built for non-technical founders and small teams who need an executive assistant but can't hire one. It runs on a cloud computer with browser and app access, so it can triage your inbox, prep you for meetings, research prospects, and draft outreach, all through a normal text or voice conversation. There's no dashboard to learn; you just message it like you would a real assistant, and it asks for your approval before taking any action outside its sandbox.

Sim is an open-source platform for building, deploying, and managing AI agents that automate work across your other tools. You design workflows on a visual canvas, connect them to 1,000+ integrations like Slack, HubSpot, and Notion, and run them with any major LLM provider. It's aimed at technical teams, not casual users, though the visual builder keeps it from feeling like pure code.
