Pro is for people who need custom fonts or lots of credits. | Pro is the sweet spot for most people because it adds document uploads and the MCP server. Move to Team only when several people need decks on the same brand template. Prices are per user. | Start on the free Personal plan with a real data set. If you use it every week, Pro is enough for most people; move to Business only if you keep running out of AI credits. Monthly billing costs about 10% more than the yearly prices shown. |
