Manus

Manus is an autonomous AI agent that takes a high level goal and executes it from start to finish without constant supervision. You give it a task and it browses the web, writes code, creates files, generates slides, and delivers a finished result, acting more like a junior employee than a chat assistant. Now part of Meta, it runs on a credit based system with a free tier and paid plans from $19 a month. It's best suited for researchers, founders and analysts who need complex multi step work done rather than quick answers.
