Pricing

Plans as listed on each vendor's site when we last checked. Confirm before you buy.

Attribute	Kagi	NotebookLM
Plans	Trial Free Seeing the difference.	FreeOur pick Free Almost everyone. Try this before paying for anything.
	Starter $5/mo Light searchers.	Google AI Plus $4.99/mo People who hit the free limits now and then.
	ProfessionalOur pick $10/mo Anyone who searches every day.	Google AI Pro $19.99/mo Heavy users who also want Gemini Pro and Deep Research.
	Ultimate $25/mo Heavy AI users.	Google AI Ultra From $99.99/mo Power users who want the top of everything Google offers.
	Duo and Family Duo $14/mo, Family $20/mo Couples and households.
Which plan to pick	Use the free trial for a week, then take Professional. 300 searches on Starter goes in a couple of weeks for most people. Only pay for Ultimate if you'd otherwise pay for an AI chat subscription, since it bundles the top models. Yearly billing saves 10%.	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.

Pros and cons

Attribute	Kagi	NotebookLM
Pros	No ads, sponsored results or tracking You control which sites show up and where AI assistant with a choice of top models Fair pricing: unused months are credited back	Answers only from your sources and cites the exact passage Free plan is big enough for most small businesses Accepts PDFs, Docs, websites, YouTube and audio as sources Audio Overviews are a clever way to get people to engage with research Simple enough that you can hand it to anyone on the team
Cons	It costs money, and Starter's 300 searches run out fast Top AI models only on the $25 Ultimate plan Local results like maps and shops are weaker than Google's API and MCP use is billed separately from the search plans	Will not research the open web unless you explicitly ask it to find sources Answers can be surface-level on dense material; you still need to read the key parts Audio Overviews take a few minutes and sound alike after a while No way to script or automate it; everything happens in the browser
