Agentastic is a personal AI agent for macOS. It runs quietly in the background and appears on demand, anywhere on your Mac, so you can get intelligent help without switching windows or losing your flow.
More than a chat box
Most AI tools live in a separate browser tab and only know what you paste into them. Agentastic is different in three ways:
- It's everywhere. A single global hotkey opens the launcher over your current app: editor, browser, mail, terminal, design tool. It can read your screen, your selected text, and your open browser tabs when you ask it to.
- It can act, not just answer. In agent mode, Agentastic uses tools: it browses the web, reads and writes files, runs code and shell commands, controls the browser, and calls external services, pausing for your approval on sensitive actions.
- It's model-agnostic. Connect Anthropic, OpenAI, and the Agentastic cloud provider, and switch between dozens of models per request, or let Agentastic pick the best model for the job.
Who it's for
- Developers: scaffold code, run commands, debug, and automate repo chores from your editor.
- Writers & professionals: draft, rewrite, summarize, and research with your documents in context.
- Power users: wire up messaging bots, schedule recurring tasks, and build specialized agents.
- Everyone: ask questions, dictate notes, and get things done faster, in any app.
The pieces
Agentastic ships as a small suite that works together:
- The Launcher: the keyboard-summoned window where you chat, run agents, dictate, and capture your screen.
- Settings: where you connect providers, install skills, configure tools, set up the Gateway, and manage automations.
- The background service: the daemon that runs the agent, executes tools, and powers schedules even when the launcher is closed.
