The Agent

The Agent is a desktop app from Parallax AI that lets you create named agents for different jobs and run them together on your own computer. Each agent has a purpose, instructions, its own reference documents and an ordered list of engines, such as a Claude or Codex subscription, an API key, a local model or Parallax credits. It is available for Windows, macOS and Linux (version 1.0.7) and works without an account.

What It Is

The Agent is a local multi-agent desktop application. You define agents (for example a Coder, Researcher or Writer), call one or several of them in a single message with @ mentions, and each handles its own part. An agent answers with the first engine in its list and moves to the next when it hits a usage limit, runs out of credits or is not running. Per agent, you choose whether it asks first, edits files on its own, or runs everything automatically.

Tools, Skills and MCP

Built-in tools work across every engine: files, terminal, web search, a browser (Chrome or Edge in a separate profile), image and speech generation, memory, and approvals. Skills are short Markdown guides in the open SKILL.md format; they can be added from the Parallax skills gallery, written by hand, or saved from something the agent just did. Users can add up to 20 remote or local MCP servers, and signing in connects the official Parallax MCP server, which exposes Parallax services through three tools.

Messengers, Schedules and Monitoring

Agents can be reached through Telegram, Discord, Slack, Signal or email bots that run on your computer and talk to the messenger directly. Scheduled tasks can run as often as every 5 minutes or at set times on chosen weekdays, even with the window closed to the tray, and report to a desktop notification or messenger. A monitoring timeline shows each agent's tasks as running, done, failed or waiting for approval, with progress saved every 15 seconds.

Data, Remote Control and Cloud

Conversations, agents, memory, skills and schedules are stored locally, while API keys and tokens go in the system keychain. The Claude and Codex engines use the official CLIs that the user signs in to, so The Agent does not see those logins. With a Parallax account and Allow remote control turned on, agents can be commanded from parallax.kr/agent, with risky steps approvable on the web or the computer. An optional Agent Cloud service keeps agents, bots and schedules running on Parallax servers when the computer is off.
