Which plan to pickUse 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.Standard covers most individuals; watch the usage dashboard on your first big job. Move to Business when several people need it or you want to run it on your own AI account.Get the lifetime Pro licence if you just need to edit PDFs, since it pays for itself in under two years. Add the AI assistant only if you won't use Claude, ChatGPT or NotebookLM for summaries. There's a 30-day money-back guarantee.
