What real users say: Cai vs Locus Robotics

Not marketing copy and not our opinion — a structured sweep of public discussion (reviews, forums, communities and video comments), showing what people praise and what they complain about for each tool.

Cai

60 mentions across 4 sources · 48% positive — mixed (averaged across 4 sources)

Hacker News, Product Hunt, GitHub, Lemmy

What users praise

  • • Local AI runs out of the box with Ministral 3B, no account needed.
  • • ⌥C shortcut is a clever, low-friction trigger next to ⌘C.
  • • MIT licensed, free, and zero telemetry — full transparency.
  • • Action chaining lets you pipe selection through AI, scripts, and apps.

What frustrates them

  • • Mac-only — no Windows or Linux support at all.
  • • Very thin community feedback; reliability and support are unproven.
  • • Custom action creation requires scripting skill (shell, AppleScript).
  • • No visible sync or backup for custom actions across machines.

Who should pick which

  • Solo macOS developer
    Pick: Cai

    Free, local AI actions for quick issue creation, text processing, and automation without leaving the keyboard.

  • High-volume 3PL warehouse manager
    Pick: Locus Robotics

    AMRs with Locus Array boost picking productivity 2-3x, integrate with WMS, and scale via RaaS.

  • Privacy-conscious writer
    Pick: Cai

    All AI runs locally (Ministral 3B) with no cloud; press ⌥C to summarize, translate, or fix grammar.
