Pros and cons

Kagi

Pros

  • No advertising; revenue comes from subscriptions.
  • Site-level raise, lower and block controls let users tune results.
  • Lenses give quick topic-specific filtering such as Academic or Forums.
  • Ultimate bundles access to Claude, GPT and Gemini models in Assistant.
  • Public APIs and an MCP server support developer use.
  • Transparent funding history published by the company.

Cons

  • No permanent free tier: the trial is limited to 100 searches.

  • Reviewers report that lens use and loading more results can count as extra searches.

Gemini Notebook

Pros

  • Answers cite the uploaded sources, so claims can be checked against the original text
  • Free Standard tier with 100 notebooks and 50 sources per notebook
  • Wide range of outputs, including Audio Overviews, Video Overviews, mind maps, flashcards, quizzes and slide decks
  • Accepts PDFs, websites, YouTube videos, audio files, Google Docs and Google Slides
  • Available on web, iOS and Android, and synced with the Gemini app

Cons

  • Works from the sources you add and is not built for live web news search
  • Higher limits require a Google AI subscription; Ultra starts at $99.99 per month
  • The cloud computer for code execution started with Ultra and Workspace AI Ultra Access customers, with Pro rollout still described as upcoming
  • No public API for the consumer product, and the renamed brand can make older guides and app listings confusing
