Cai (⌥C) is a macOS utility that runs AI actions on anything — selected text, clipboard content, active app context — with a single keyboard shortcut, entirely locally. It ships with Ministral 3B bundled, so it works offline out of the box with no API key, no account signup, and no network requests. For developers who prefer their own stack, it also connects to Ollama, LM Studio, Apple Intelligence, and OpenRouter. Beyond text transformations, Cai acts as a local automation layer: it can open GitHub issue drafts in your browser, create Linear tickets from selected text, run custom shell scripts, and chain multiple actions together. The whole thing is MIT licensed and open source. The UX is intentionally minimal — no chat interface, no persistent window — just a quick invocation overlay that appears, acts, and disappears. The positioning is clear: Cai competes with productivity tools like Raycast AI and PopClip, but wins on the privacy angle. There's no vendor seeing your prompts, no subscription creep, and no dependency on internet connectivity. For developers, writers, and researchers working with sensitive content who want AI assistance without cloud exposure, Cai fills a real gap that bigger AI apps can't — or won't — fill.

Microsoft Copilot Studio now supports autonomous multi-step agent flows that can execute complex business processes end-to-end without constant human intervention. Configurable approval checkpoints let organizations pause execution and require human sign-off before sensitive or high-stakes steps proceed. The update is rolling out to all enterprise tenants, making AI-driven process automation a first-class feature of the Microsoft 365 ecosystem.
Reviewer scorecard
“I set up Cai with a custom action to take a stack trace from my clipboard and open a pre-filled GitHub issue in 10 minutes. The Ollama backend means I can use a larger local model when I'm at my desk and fall back to Ministral 3B on the go. MIT license means I can fork it and add my team's internal tools.”
“Approval gating is the missing piece that makes agentic automation actually deployable in enterprise environments — no sane IT team would ship fully autonomous flows without it. The low-code interface means you don't need to babysit every integration, and hooking into existing Power Automate connectors is a massive time saver. My only gripe is that debugging a failed mid-flow agent step is still too opaque.”
“Ministral 3B is fine for basic text tasks but it stumbles on anything requiring real reasoning or domain knowledge. Most users will hit its limits quickly and need to set up Ollama anyway — which is a non-trivial setup process for non-developers. The privacy story is genuine but the capability bar is lower than what cloud alternatives offer.”
“Microsoft is slapping the word 'autonomous' on what is essentially a glorified Power Automate flow with a chatbot skin — the approval gating is good, but let's not pretend this is AGI for your procurement department. Pricing is buried in enterprise licensing labyrinths, and you'll spend more time negotiating your tenant config than actually building agents. Come back when the observability and error-handling story matures.”
“Cai represents a class of tools that become dramatically more useful as on-device models improve. When Bonsai-scale 1-bit models hit 8B+ quality at 131 tokens/sec locally, Cai's architecture is exactly right — a minimal, composable action layer on top of local inference. The MIT license means the community will build the plugin ecosystem.”
“Human-in-the-loop approval gating isn't just a safety feature — it's the trust scaffolding that will get boardrooms to actually greenlight agentic AI at scale, and Microsoft is smart to ship it now. This positions Copilot Studio as the enterprise on-ramp for the agentic era, directly competing with Salesforce Agentforce and ServiceNow's AI workflows. The org that figures out which checkpoints to automate away next year will have a serious competitive edge.”
“I've been looking for a way to do quick AI rewrites and tone adjustments in any app — not just in a web browser — without pasting things into a chat interface. Cai works in Figma, Notion, Miro, everything. The local privacy angle matters a lot when I'm working on client content that's under NDA.”
“If your work lives in Word docs and Figma files, this update is basically invisible to you — it's laser-focused on back-office process automation rather than anything creative. The Studio UI is cleaner than it used to be, but it still feels like a flowchart tool that got possessed by a language model. Creatives should wait for Microsoft to bring these agent capabilities into Designer or Loop before getting excited.”
