CielChan is an intelligent anime desktop AI companion that lives on your screen as a transparent overlay. Fully offline, completely private, and yours forever.
See her in action — animated, responsive, and always present.
Whether you're working late, gaming alone, or browsing through another quiet evening, Ciel is there. She stays quietly nearby, always ready when you feel like talking.
Conversations, voice data, and AI activity stay entirely on your computer. Nothing is ever sent to external servers. Your privacy isn't a setting — it's built into how CielChan works.
Subtle breathing, idle motion, dynamic hair physics, and cursor-tracking head movement make Ciel feel genuinely present on your screen.
Ciel recalls past conversations and builds familiarity over time. Interactions feel natural and personal the more you talk with her.
Smart click-through technology keeps her out of your workflow until you want to interact. Drag, resize, and position her anywhere.
Optionally enable screen observation and let Ciel comment on what you're doing — she can narrate your work, continue a story, or simply offer calm company. Runs automatically in the background when enabled, or stays quiet until you speak.
Ciel can do more than talk. Set reminders, fetch information from the web, read and write text files, and assist with lightweight tasks — a quiet helper that does things as well as listens.
No accounts, no API keys, no configuration. Install the app, launch it, and Ciel is ready to talk immediately.
No subscriptions, no server outages, no internet required. Install once and Ciel will always be on your desktop.
CielChan's interface and voice conversation support multiple languages out of the box, with expanded multilingual capabilities in the Plus version.
Additional languages and voices continue to expand with future updates.
Take customization further with CielChan Plus. Load and use your own custom VRM models created in VRoidStudio or any VRM-compatible tool.
Change your companion's appearance, outfits, and style to truly make her your own.
