What is it?

AionUi is a desktop app for working with AI agents on your own computer. It includes a built-in agent that can read and write local files, search the web, generate images, and use MCP tools, so it works without installing any CLI tools. You bring your own API key from providers such as Gemini, OpenAI, Anthropic, DeepSeek, or a local Ollama instance.

If you already use terminal agents, AionUi auto-detects installed ones such as Claude Code, Codex, Gemini CLI, and OpenCode and lets you run them side by side in one interface. Team Mode lets a Leader agent split work into subtasks and delegate them to Teammate agents running in parallel, sharing a workspace and a task board.

The app also supports scheduled tasks using cron expressions, intervals, or one-time triggers, plus a WebUI and chat integrations with Telegram, Lark, DingTalk, and WeChat for remote control. A preview panel displays PDF, Office, code, Markdown, and image files. Data is stored locally in SQLite.
