Which plan to pickFree is fine for a document or two a day. Before paying for Plus, try NotebookLM, which is free, or use Claude or ChatGPT if you already pay for one.Free is enough to see if it fits how you work. If you'll put visuals in client decks, Plus removes the branding and adds PowerPoint export for $9 a month on yearly billing. 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.
