On Business you only get single-file questions and must buy AI units. Ask sales to estimate your AI unit use before signing. | Start on Free for a couple of weeks of real consults. If it saves you time every day, trial the Clinician plan; if you need notes to flow into your practice software or want one bill for the clinic, ask about Practice. | Beginner is fine until you hit the five-project wall. Pro on the yearly plan is the obvious move after that. Business is for teams who want a shared space; it is not a substitute for a real project tool. |
