AionUi is a cross platform desktop application that transforms command line AI agents into an intuitive graphical interface. It detects locally installed AI CLI tools and presents them in a structured environment where users can manage conversations, sessions, and files more efficiently.
The software is open source, allowing users to customize and extend its functionality according to their workflow requirements.

Highlights
Smarter first-run experience
- The welcome page's default prompt suggestions are now task-oriented — "explain this project", "find duplicate files in this folder", "build me a personal homepage" — so the first click shows real value instead of asking the agent to introduce itself. Available in all 13 languages.
- Prompt suggestions got a cleaner look: plain left-aligned text with a subtle hover arrow, replacing the old full-width bordered cards.
Easier assistant & agent discovery
- The "More" assistants dropdown on the home page is now a wide multi-column panel that opens on hover and adapts its column count to the window size — much faster to scan when you have many assistants installed.
- Agent, Assistant, and Scheduled Task settings pages now have a search box, so you can filter long lists instantly (hidden on mobile where space is tight).
Team mode reliability
- Fixed a deadlock where a team session reclaimed by idle cleanup would silently swallow your next message into the draft box and never recover. Idle-stopped sessions are now treated as recoverable, and the engine broadcasts the stopped status so the UI stays in sync.
Windows installer safety
- The installer now checks CPU architecture before touching the registry. Previously, running an arm64 installer on an x64 machine could damage the existing correct install's registry entries before aborting. Error messages now report the actual detected architecture (e.g.
target=arm64 actual=x64).
Engine updates (AionCore v0.1.48 → v0.1.49, Aion CLI runtime v0.2.5 → v0.2.6)
- 18 new built-in agents synced from the public ACP Registry: Amp, Devin, Junie (JetBrains), Grok Build, Kilo, Cursor Agent, GLM Agent, Poolside, Nova, DeepAgents, Cortex Code, VT Code, Autohand Code, Stakpak, Dirac, DimCode, siGit Code, and Corust Agent. Each requires its own product CLI installed on your PATH — AionUi detects the CLI and manages the ACP connection with pinned, validated package versions.
- OpenAI Responses API support: the Aion CLI runtime (aionrs) now speaks the Responses API, and GPT-5.6 requests are routed through it for better compatibility.
- Streaming errors now come with sanitized diagnostics, making provider stream failures easier to report and debug (cancelled streams no longer produce noise).
- Added a conversation rename command.
- Idle-cleanup timeouts are longer by default and can be tuned via environment variables, so long-running sessions are reclaimed less aggressively.
- Max token limits are no longer incorrectly applied to AionUi requests.
Bug Fixes
- The keep-awake (prevent system sleep) setting is now applied by the backend engine, fixing cases where it silently didn't take effect. If keep-awake wasn't working for you before, toggle the setting off and on once after upgrading.
