Pros and cons

Grok

Pros

  • Searches both X posts and the web for current information
  • Free tier available without a subscription
  • Image and video generation in the same app as chat
  • Separate API with long context windows (up to 1M tokens on some models)
  • Real-time voice mode in the mobile apps

Cons

  • Free usage is capped, and xAI does not publish the exact limit
  • Usage limits are given only as multiples of the Plus plan, not as fixed numbers
  • Answers drawing on X posts can reflect unverified social content
  • The App Store rates the app 16+ because of mature themes

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.
  • The $5 Starter plan caps searches at 300 per month, which users report running out of quickly.
  • Reviewers report that lens use and loading more results can count as extra searches.
  • Full AI model access requires the $25 Ultimate plan.
