Am I too late to this?
No — you're early to the part that lasts. The prompt tricks and tool-hopping of the last two years are exactly what Tomanai makes unnecessary. You're skipping the awkward phase, not missing it.
How long until I'm productive?
Your first request takes about two minutes to write. Most people accept their first finished piece of work within the week. There is no course, no certification, no setup project.
Do I need technical skills at all?
If you can write an email that says what you want and when you want it, you have every skill this requires. The agents handle models, tools, and orchestration — invisibly.
How is this different from a chatbot?
A chatbot answers while you sit there. Tomanai agents take work away, do it over hours or days, keep a live status board, and bring finished work back for your sign-off. You delegate; you don't converse.
