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.

Opera Neon

Pros

  • Combines chat, browser actions, research and content creation in one browser rather than a separate extension.
  • Neon Do shows its plan and actions in real time and can be paused or taken over.
  • Wide model choice across OpenAI, Anthropic, Google, xAI and open-weight models on the Standard plan.
  • MCP connector and CLI let external agents such as Claude Code or n8n use a live browser session.
  • Credentials, passwords and card details are stated to stay on the device, and Opera says it does not train on user data.
  • Free VPN and ad blocker are included in the browser.

Cons

  • Full agentic features need the $19.90 per month Standard plan, higher than many AI add-ons.
  • Windows and macOS only; no Linux, iOS or Android version yet.
  • Neon Do uses cloud LLMs to plan, and page content is sent to Opera and OpenAI servers with 365-day retention.
  • Opera itself calls Neon an experimental agentic browser, so behaviour and plan limits may change.
