| Plans | FreeOur pick Free Personal use inside Claude Code. | FreeOur pick Free Almost everyone. Try this before paying for anything. | FreeOur pick Free Learning what a good prompt looks like. |
Pay as you go From $4 per 1,000 searches Anyone whose usage outgrows the free credit. | Google AI Plus $4.99/mo People who hit the free limits now and then. | Individual $8/mo People who use it daily and want prompts in their own voice. | |
Enterprise Custom Companies building products on top of it. | Google AI Pro $19.99/mo Heavy users who also want Gemini Pro and Deep Research. | 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. | |||
| Which plan to pick | Start free. The monthly $10 of credit is plenty for one person using it from Claude Code, and if you do run out you only pay for what you use. Enterprise is for software companies, not for a business that just wants better search. | 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. | 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. |
