|---|---|---|---|
| Plans | FreeOur pick Free Personal use inside Claude Code. | FreeOur pick Free Almost everyone. Try this before paying for anything. | Free Free The occasional big question. |

Google AI Ultra From $99.99/mo Power users who want the top of everything Google offers. | Google AI Ultra From $99.99/mo Power users who want the highest limits across all of Google AI. | ||
| 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. | Try the free plan first; it is enough to see the style of report you get. If you want it weekly, Google AI Pro is the pick because the Pro model writes better reports and the same subscription upgrades NotebookLM and Gemini in Gmail and Docs. |
