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.

Deploy Hermes is a managed hosting platform purpose-built for Nous Research's Hermes agents—giving anyone the ability to deploy a persistent, private AI agent on Telegram, Discord, or Slack without managing servers. You connect your bot credentials and choose your AI provider (OpenAI, Anthropic, or others via your own API key), and the agent is live in under 60 seconds with encrypted key storage and isolated runtime instances. What distinguishes this from generic cloud functions or Docker deployments is the feature set baked into the managed layer: persistent memory across restarts, scheduled jobs (up to unlimited on the Power tier), browser automation, web search, and custom skill development. Health checks, updates, and restarts are fully automated. You pay for compute, not for the AI calls themselves—bring-your-own API keys means you control the LLM costs directly. Launching on Product Hunt today (April 6, 2026) with a 25% launch discount (code: PHLAUNCH25), pricing starts at $16/month for basic bot hosting, $32/month for automation with scheduled jobs, and $63/month for parallel workloads. This is essentially Heroku for Hermes agents—the platform abstraction that lets builders focus on agent behavior rather than infrastructure.
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 bring-your-own-API-key model is the right call—you only pay for the hosting, not a markup on tokens. Persistent memory, scheduled jobs, and browser automation for $32/month is a genuinely strong deal for a solo builder who wants a capable personal agent on Telegram without managing a VPS.”
“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 is Hermes-specific hosting—if you want to run any other agent framework, it doesn't apply. You're betting on Nous Research's Hermes ecosystem staying relevant, and you're paying a persistent monthly fee on top of your own API costs. For developers comfortable with a VPS, Railway, or Fly.io, the value proposition is thin. The privacy claims also need scrutiny—'encrypted keys' is a marketing statement, not a security architecture.”
“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.”
“Managed agent hosting is a real category forming right now—Maritime, Deploy Hermes, and a dozen others are racing to become the Heroku of the agent era. The winner will be whoever locks in the best developer experience and the most reliable uptime. Hermes has 27k GitHub stars and serious momentum; Deploy Hermes is riding that wave intelligently.”
“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.”
“A persistent AI agent on my Telegram that I can ask to do research, schedule tasks, and browse the web—without me needing to know what Docker is—for $16 a month. I'll try the free tier today. The setup under 60 seconds claim is either exactly right or wildly optimistic; I'll find out soon.”
