"AI app" now covers everything from a chat window to a tool that adds one AI button to a photo editor. That makes most lists of AI apps for Mac hard to use. This guide sorts the AI apps in the Mac Directory catalog by how much of the app is AI: apps that are an assistant, apps that run an agent for you, and established tools that added an AI feature to a job you already do.
What each app does comes from its maker's site. Install details come from the app's catalog page, which for these apps comes from its Homebrew cask. Where the maker's site does not say something, such as a price, this guide does not either.
Which app is a general AI assistant for the Mac?
5ire is the general-purpose pick. Its site calls it "an open source cross-platform desktop AI assistant and MCP (Model Context Protocol) client." It supports a local knowledge base and a custom prompt library. The Homebrew cask describes it as an AI assistant and MCP client.
The MCP part matters if you use more than one model or tool. An MCP client can connect to MCP servers that expose tools and data, so the assistant is not limited to what the chat window can do. Because 5ire is open source and cross-platform, it suits people who want to see how the app works or use the same assistant on more than one operating system.
Which apps run an AI agent for you?
An agent does a task over several steps rather than answering one message. Two catalog apps are built around one.
Amp is a coding agent. Its download page offers "the Amp coding agent beta apps for Mac, iPhone, iPad, and Android." The Mac app requires Apple silicon and macOS 26 or later, updates itself, and can be installed from the site or with Homebrew. You sign in with the same account you use on ampcode.com. The Homebrew cask describes Amp as a coding agent and development environment. Because the apps run on phones and tablets too, you can check on a thread away from your desk.
AirBuild is narrower. Its site says it uses "AI agents to build your app and handle App Review." Specialized agents submit the app, respond to Apple, fix rejection issues and resubmit, the site says, without manual handoffs. The output is a native iOS app, and AirBuild has a macOS download. At the time of writing its site asks visitors to join a waitlist and says early access is limited, so check availability on its page before planning around it.
Which Mac tools added an AI assistant?
Some of the most useful AI on a Mac sits inside a tool you would install anyway.
Almighty is a collection of "over 100 Mac tweaks and utilities in one native app." Its assistant, Zeus, takes a typed or spoken request such as "Turn dark mode on", finds the right tweak and runs it. The site says Zeus can use Apple Intelligence on your Mac, Claude Code, Codex, or any OpenAI-compatible API. That choice is the reason to pick it: you can keep requests on the Mac with Apple Intelligence or send them to a provider you already pay for. Almighty is free to download and says it collects no analytics.
Amore helps developers ship Mac apps outside the App Store, handling Sparkle updates, code signing, notarization and DMG creation. Its home page includes a "Set up with AI" prompt you paste into a coding agent, plus an Amore skill that installs into Claude Code. The AI here is not inside Amore; it is a set of instructions that lets your coding agent drive Amore's command line.
4K Video Downloader Plus downloads video and audio from YouTube and similar services. Its product page lists AI processing to "enhance sound in videos with AI." It is a downloader first, with AI as one feature.
Which app keeps AI agents away from your passwords?
Once an agent can act for you, it needs access to accounts. 1Password markets 1Password for Agents with the line "Give AI Agents access, not your passwords," and its site describes securing AI tools alongside passwords and secrets. For scripts and terminals, the 1Password CLI is also in the catalog; its Homebrew cask describes it as a command-line interface for 1Password.
If you run Amp, 5ire with MCP servers, or any other agent, decide how it gets credentials before you give it work. A secrets manager is a better answer than pasting keys into a prompt.
How should I choose an AI app for Mac?
Pick by the job, then check the requirements:
- Ask questions and use tools from one window. 5ire.
- Write and change code with an agent. Amp, if you have Apple silicon and macOS 26.
- Get an iOS app built and through App Review. AirBuild, once you have access.
- Control your Mac by asking. Almighty.
- Give agents access safely. 1Password.
