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.

Google Workspace Studio

Google Workspace Studio is a no-code platform that lets business users build and deploy AI agents across Gmail, Docs, Sheets, Drive, Meet, and Chat by describing what they want in plain language. It began rolling out to Workspace Business, Enterprise, and Education customers starting March 2026, with broader general availability through April. The core experience is conversational: describe an automation like "every Friday, ping me to update my project tracker" and Gemini creates and deploys the agent. More complex agents can connect to third-party apps including Asana, Jira, Mailchimp, and Salesforce via prebuilt connectors, webhooks, or Apps Script. No YAML, no flow diagrams, no IT ticket required. Workspace Studio is Google's counter to Microsoft Copilot Studio and OpenAI's Workspace Agents — a recognition that the next wave of AI adoption will be driven by non-technical workers who need automation power without engineering overhead. If it delivers on its "describe it and it's done" promise, it could make bespoke AI workflows a standard expectation for every knowledge worker on a Workspace plan.
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.”
“The Apps Script escape hatch is what makes this actually useful for builders. You can start with natural language for simple automations and drop into code when you need custom logic — that's the right design for a no-code tool. Happy to recommend this to non-technical stakeholders.”
“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.”
“This 'describe it and it's done' framing always sounds better than the reality. Complex multi-step workflows built by non-technical users tend to break in unexpected ways, and support options for debugging a Gemini-generated agent are unclear. Also: you're locked into the Google Workspace ecosystem completely.”
“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.”
“Google distributes Workspace to 3 billion people. When AI agent building becomes a standard feature of every Gmail account, that's not a niche developer tool — it's a civilizational shift in how knowledge work gets done. The long-term implications of every office worker having a personal automation layer are enormous.”
“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.”
“As someone who lives in Google Docs and Gmail, the ability to wire up a 'summarize and reply to client emails' agent without involving a dev is exactly what I've wanted for years. The Jira and Asana connectors mean it fits into actual creative agency workflows too.”
