Pros and cons

Duck.ai

Pros

  • Free tier works without an account.
  • Personal metadata such as IP address is removed before prompts reach providers.
  • Chats are not used for training by DuckDuckGo, and providers agree not to train on them.
  • Several providers' models are available from one interface.
  • Plus ($9.99/month) bundles a VPN and identity protection services.

Cons

  • Free tier is limited by daily usage caps, and the paid limits are not published as numbers.
  • Strongest models are subscriber-only, and the top tier costs $19.99/month.
  • No public API and no standalone mobile app found.
  • Chat history is local by default, so it does not sync across devices without opting into Sync & Backup.

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
