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
Conversation Header & Mobile Polish
- Refreshed the conversation header on desktop: model selector moved to the right, agent logo sits next to the title editor, and team chats now show a Peoples icon. Model selectors (ACP & Aion CLI) gained a dropdown chevron so they look and feel consistent.
- Mobile experience is now noticeably more compact: tighter message bubbles (14px), shorter sendbox, ellipsis instead of marquee on the model pill, slimmer titlebar (no + button), and sidebar/history actions are always visible — no hover required.
- WebUI users now see the "Work in project" footnote on the new conversation page and can attach a workspace to fresh conversations, just like the desktop app.
Reliability & Crash Fixes
- The desktop and WebUI boot flow now stops cleanly when the aioncore backend fails to start, instead of cascading into confusing
__backendPort unset errors. A startup failure dialog with an optional diagnostic report is shown so problems are easier to triage.
- Packaged builds no longer crash from
EPIPE errors when console output is piped to closed stdout/stderr. File logging stays on so local diagnostics are unaffected.
- Backend launch failures are now captured as dedicated Sentry events with stage, port, paths, and stdout/stderr tails so we can actually see what went wrong.
Bug Fixes
- Fixed English text rendering with thin, hard-to-read weight on systems that have Inter installed — Arco's font stack is now overridden to use system fonts.
- Fixed the bottom ~8px of the Base URL input in the "Add Custom Platform" modal not accepting clicks because the toggle below was overlapping it.
- Switching conversations mid-upload now properly aborts the previous conversation's in-flight uploads, so you no longer see stray progress bars or thumbnails in the new conversation.
- Fixed a renderer crash when filtering workspace
@ mentions against malformed file entries.
- ACP conversation hydration no longer surfaces backend
Failed to fetch as an unhandled rejection; running/processing state resets cleanly when the local backend is temporarily unavailable.
- Opening a stale (deleted) conversation no longer triggers an unhandled 404 promise rejection — the renderer treats it as a missing conversation while still surfacing real backend errors.
