Genuinely permanently free with no trial window, credit card, or expiry required
Free tier limits (100 notebooks, 50 sources each) are generous for most individual use
Google Workspace Business Standard and above include Plus-tier access at no additional cost

Cannot be purchased standalone — paid tiers require a Google AI subscription, Workspace plan, or Cloud Enterprise license
Free tier’s 3 Audio Overviews/day and 50 chat questions/day may be limiting for heavy daily use
Recently renamed (July 2026), which may cause some confusion given its long-standing "NotebookLM" branding

Deeply integrated across Google’s broader ecosystem (Search, Workspace, Android)
Ultra tier pricing was reduced from its original $250/month, improving accessibility
API pricing offers genuinely low-cost options (Flash-Lite at $0.10/million tokens) for cost-sensitive applications

Full Workspace integration requires at least Business Standard ($14/user/month), not available on cheaper Workspace tiers
Credit-based system layered on top of tier usage limits adds complexity to understanding real usage capacity
Ultra tier’s $99.99-$199.99/month range represents significant cost for maximum usage limits and Deep Think access
