| Attribute | NotebookLM | Perplexity (Research) | Prompt Cowboy |
|---|---|---|---|
| Plans | FreeOur pick Free Almost everyone. Try this before paying for anything. | Free Free Quick sourced answers and a taste of research mode. | FreeOur pick Free Learning what a good prompt looks like. |
Google AI Plus $4.99/mo People who hit the free limits now and then. | ProOur pick $17/mo billed yearly Anyone who researches most days. | Individual $8/mo People who use it daily and want prompts in their own voice. | |
Google AI Pro $19.99/mo Heavy users who also want Gemini Pro and Deep Research. | Max $200/mo, or $167/mo billed yearly Heavy users who also want the Computer agent and the newest models first. | Team See website Small teams who want shared instructions. | |
Google AI Ultra From $99.99/mo Power users who want the top of everything Google offers. | Enterprise Pro From $40/seat/mo Teams that need admin controls and shared billing. | ||
| Which plan to pick | Stay on Free until it stops you doing something. If that happens, Google AI Pro is the sensible step because it also upgrades Gemini and Deep Research, which you will probably want anyway. AI Plus is a cheap middle step if NotebookLM is all you care about. | Pro is the one. The free plan is too tight to judge research mode properly, and Max only makes sense if you want the Computer agent or you hit Pro limits every day. Businesses with a few people on it should look at Enterprise Pro for the admin controls. | Free is genuinely enough for most people. Pay for Individual only if you are writing prompts all day and the style matching would save you editing time. Check the Team price on the site; it was not shown on the pricing page when we looked. |
