| Which plan to pick | Free 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. | Use the free credits to make two or three decks and judge the output. If you'll keep using it, Plus is the sensible step because it removes the badge and refreshes credits monthly. Only move to Pro if you want the API, custom domains or viewer analytics. | 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. |
