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.

Glean's Agents Platform is a generally available enterprise AI agent builder that lets teams create AI agents with secure, permissioned access to company knowledge indexed across 100+ business apps. Agents can trigger workflows, answer questions grounded in internal data, and integrate with tools like Salesforce, Jira, and ServiceNow. It's built on top of Glean's existing enterprise search infrastructure, making the knowledge layer the core differentiator.
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 primitive here is a hosted agent runtime that uses Glean's search index as a retrieval layer and exposes workflow triggers — essentially a RAG-grounded agent builder with pre-built connectors. The DX bet is that enterprises want a no-code/low-code surface rather than composable APIs they can wire into their own stack, which is probably the right call for the buyer but makes this nearly useless if you want to integrate it into an existing internal toolchain. The moment of truth — can a developer get an agent running against real company data in under 30 minutes — is entirely gated behind the sales cycle and enterprise provisioning, which means there's no public hello-world to evaluate. The blog post has no repo, no public API docs, no sandbox, and no pricing: three red flags for any tool claiming to serve builders.”
“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.”
“The direct competitors here are ServiceNow's Now Assist, Microsoft Copilot Studio, and Salesforce Agentforce — all of which have massive distribution advantages. Where Glean actually earns its place is the knowledge layer: if you've already got Glean indexing your company's internal content with real permissions, building agents on top of that foundation is meaningfully different from a blank-slate agent builder. The scenario where this breaks is large enterprises with fragmented IT budgets, where Glean has to compete against the existing Microsoft 365 or ServiceNow contract rather than supplement it. What kills this in 12 months isn't a competitor — it's Microsoft bundling Copilot Studio capabilities deeper into M365 E5 licenses and making the 'we already have Glean' argument harder to close.”
“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.”
“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.”
“The buyer here is the CIO or VP of IT, pulling from digital transformation or enterprise AI budget — not a departmental line item. Glean's smart move is that the Agents Platform is an expansion motion inside an existing Glean contract, not a net-new sale, which is the only land-and-expand story that actually works. The moat is real but narrow: it's the indexed, permissioned knowledge graph that takes months to build and tune per enterprise, creating genuine switching costs. The stress test is whether enterprises will consolidate on one platform player — if Microsoft or Salesforce offers 80% of this functionality bundled into existing spend, Glean's standalone value proposition compresses fast unless they keep the knowledge indexing quality visibly ahead.”
“The job-to-be-done is precise: 'help enterprise employees get answers and trigger actions using company knowledge without requiring IT to build custom integrations from scratch.' That's a real, well-scoped problem. The completeness question is where Glean has an edge over blank-slate agent builders — because the knowledge indexing is already done for existing Glean customers, the activation cost for the first useful agent should be low compared to starting from Copilot Studio with an empty SharePoint. The gap I'd flag is that 'over 100 business apps' is a connector count, not a measure of integration depth — the real test is whether an agent can reliably take action in Salesforce or ServiceNow, not just read from them, and nothing in the GA announcement quantifies that reliability at scale.”
