Pros and cons

Dia

Pros

  • Free to download, with a $20 per month Pro plan rather than a mandatory subscription.
  • AI chat can use content from open tabs and connected work apps.
  • Frequent releases: Mac v1.52.0 and v1.53.0 shipped in October 2026.
  • Separate profiles keep work and personal tabs and AI context apart.
  • Dia for Work provides SAML SSO, MDM policies and a SOC 2 Type II examination.

Cons

  • Desktop only; no publicly released iOS or Android app.
  • Windows version is new (v1.0 on October 6, 2026) and trails the Mac version.
  • Free-tier AI usage limits are not published, and the site has no public pricing page.
  • Several workflow features depend on connected work apps and a work-focused setup.

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.
