Vorker drafts the workshop designs, decks, follow-ups and invoices trainers write after hours, and checks in with participants 90 days on. You approve it all.

No. Every email, survey and invoice is prepared and then waits for you. You can read it, edit it, reject it, or approve it and schedule it to go out later. The 90-day check triggers on its own, but the send still waits for your press.
It drafts from your own past designs, your exercises and your method, so the first draft is your style, not a generic template. You are the one who knows what works in a room; it just gets you to a full draft before the coffee goes cold.
One-person firms get the most out of it, because there is nobody else to hand the deck, the follow-ups and the invoicing to. Vorker is built for businesses of one to ten people, not for training departments.
Photograph the hotel bill or the train ticket and it is booked with the tax split out and the image attached, filed against the client and the delivery. You can ask what any workshop actually cost you to run.
When the package is approved, Vorker notes the delivery date. Ninety days on it drafts a short survey to the participants and holds it for you. The results go into a summary you can send HR, which is often what wins the next booking.
No. You type or say what you need, the way you would brief a producer, and Vorker works inside the tools you already have: your email, your calendar, your files, your accounting.
