A free, open-source, Cowork app with AI Agents Built-in Agent | Zero Setup | Any API Key | Multi-Agents | Remote Access | Cross-Platform | 24/7 Automation
AionUi is more than a chat client. It's a Cowork platform where AI agents work alongside you on your computer — reading files, writing code, browsing the web, and automating tasks. You see everything the agent does, and you're always in control.
Claude Code, Codex, Qwen Code, Kiro, Hermes Agent, Snow CLI, Cursor Agent and 16+ more — auto-detected, unified interface

Built-in Agent — Install & Go, Zero Configuration
AionUi ships with a complete AI agent engine. Unlike tools that require you to install CLI agents separately, AionUi works the moment you install it.
No CLI tools to install — the agent engine is built in
No complex setup — sign in with Google or paste any API key
Full agent capabilities — file read/write, web search, image generation, MCP (Model Context Protocol) tools
Ready-to-use assistants — 20 built-in professional assistants (Cowork, PPT Creator, Word Creator, Excel Creator, Morph PPT 3D, Pitch Deck Creator, Dashboard Creator, Academic Paper Writer, Financial Model Creator, and more) ready to use immediately
Office assistants — PPT, Word & Excel
These tracks match what the app actually ships: Morph PPT presets and the pptx / docx / xlsx skills (see assistant/ presets and skills/ in the repo). Want document/table output? AionUi’s built-in OfficeCLI helps PPT (Morph), Word (.docx), and Excel (.xlsx/.xlsm/.csv) go from request to deliverable faster and more reliably.
The three assistant types map to file workflows, and the final outputs are directly editable and reusable.
PPT assistant
Output: editable Morph PPT (.pptx)
Morph-animated slide-to-slide transitions with coherent story pacing; powered by OfficeCLI.
Word assistant
Output: editable Word (.docx)
Paper/thesis writing and production-ready document editing via the docx skill; powered by OfficeCLI.
Excel assistant
Output: usable Excel (.xlsx/.xlsm/.csv)
Generate/refresh spreadsheets with xlsx for analysis, auto-formatting, and charts; powered by OfficeCLI.
Multi-Agent Mode — Already Have CLI Agents? Bring Them In
If you already use Claude Code, Codex, or Qwen Code, AionUi auto-detects them and lets you Cowork with all of them — alongside the built-in agent.
Supported Agents: Built-in Agent (zero setup) • Claude Code • Codex • Qwen Code • Goose AI • OpenClaw • Augment Code • CodeBuddy • Kimi CLI • OpenCode • Factory Droid • GitHub Copilot • Qoder CLI • Mistral Vibe • Nanobot • Aion CLI (aionrs, the Rust-based backend service bundled with AionUi) • Snow CLI • Kiro • Hermes Agent • Cursor Agent and more
Auto Detection — automatically recognizes installed CLI tools
Unified Interface — one Cowork platform for all your AI agents
Parallel Sessions — run multiple agents simultaneously with independent context
MCP Unified Management — configure MCP (Model Context Protocol) tools once, automatically sync to all agents — no need to configure each agent separately
YOLO Mode (auto-approve all agent actions without manual confirmation) / Full-Auto Mode — one click to bypass permission prompts; all agents support full-auto mode for unattended execution
Team Mode — Coordinated Multi-Agent Collaboration
Run multiple AI agents as an organized team: a Leader agent receives your instructions, breaks them into subtasks, and delegates to Teammate agents via a built-in Team MCP Server. Teammates execute in parallel, share results through an async mailbox, and write to a shared task board.
Parallel multi-agent execution — Leader breaks tasks into subtasks and delegates to Teammate agents running in parallel; each Teammate uses its own model via ACP (Agent Communication Protocol, AionUi's multi-agent coordination layer), Gemini, or Aionrs
Leader orchestration — Leader assigns, tracks, and aggregates results; supported backends include Claude Code, Codex, Gemini, Snow CLI, and Aion CLI
Team-isolated workspace — all agents share the same folder; each has its own permission dialog with sidebar badge for pending approvals
🔍 View Team Mode Details ▶️
Shared Workspace — all agents read/write the same folder; the file panel stays visible throughout
Supported backends — Claude Code, Codex, Gemini, Snow CLI, Aion CLI (aionrs); other ACP backends with mcpCapabilities.stdio are auto-supported
Dynamic scaling — add or remove Teammates while the team is running; silent agents auto-escalate to failed with one-click removal
Granular permissions — each agent has its own permission confirmation dialog; sidebar badge shows pending approvals
File sharing — Leader can pass file attachments to Teammates
