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.

Felo

  • Combines cited search with slides, images, video and agents in one subscription.
  • Pro plan at about $15 per month includes API access.

Cons
