Kagi - strengths & limits

Strengths

  • No ads means ranking is not shaped by advertisers
  • Personal ranking rules fix the results you keep skipping
  • Reader and summariser features come bundled with search

Watch out for

  • No meaningful free tier: it is a paid product from day one
  • Search quality still varies on niche or local queries
  • Costs are per person, which adds up for a larger team

NotebookLM - strengths & limits

Strengths

  • Answers stay grounded in your sources and cite the passage used
  • Handles long, dense documents that are slow to read end to end
  • Free with an ordinary account and no setup beyond uploading files

Watch out for

  • Uploaded material leaves your machine, so sensitive files are a risk
  • No open-web search: it cannot go beyond the sources you provide
  • Source and usage limits change between tiers without much notice

Which should you choose?

If your priority is privacy-minded research, ad-free search, custom result ranking and reading long pages, Kagi is the stronger pick. If instead you care more about paper reading, report summarisation, study notes and literature triage, go with NotebookLM. For most people, trying both on a free tier is the fastest way to decide - they serve the same AI Search & Knowledge space but differ in workflow and output style.
