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.

Kimi

Pros

  • International USD plans start at $19/month and include Kimi Code and Agent Swarm.
  • Broad agent toolset: deep research, slides, documents, spreadsheets, website building and scheduled tasks.
  • A separate pay-per-token API with a 1M-token context window on K3.
  • Rated 4.7 out of 5 from 5.3K ratings on the US App Store.
  • Earlier K2-family models were reported to have downloadable weights, which suits self-hosting teams.

Cons

  • Free-tier limits are not clearly published on the help pages.
  • Plan structure is changing: legacy plan names (Moderato, Allegretto, Allegro, Vivace) coexist with Plus, Pro, Max and Ultra, which can confuse buyers.
  • Credits do not roll over, and one shared pool covers chat, agents and Kimi Code.
  • The site interface and several help pages default to Chinese; I found no confirmed Android or Windows client.
