AI Summaries

Missed a busy group chat? AI summaries give you the highlights in seconds so you can jump right back in with full context. No more endless scrolling.
Standalone AI
Ask Celes anything.
Need a longer conversation with your AI assistant? Open a dedicated chat for research, brainstorming, catching up on news, or just asking questions. Celes knows your chats and can tell you what needs your attention.
What's yours stays yours.
We don't train AI on your messages, we don't sell your data, and we don't show ads. Your conversations are private, and they stay that way.
No AI Training
We never train AI models on your messages. Our AI provider is contractually prohibited from training on your data too.
No Ads, Ever
No ads, no cross-app tracking, no device fingerprinting, no advertising profiles. We answer to our users, not advertisers.
Encrypted Everywhere
AES-256 encryption at rest, TLS in transit. Your data is protected with the same standards used by banks and governments.
