Celestra One app.
Every model. Every task.
Celestra AI is an AI assistant that chats across 33+ frontier models, runs multi-step agents, and keeps working in the background — all from one app with live voice input.
Built to actually do things
Not another chat wrapper. Celestra ships the full stack: models, voice, agents.
1 Multi-Model Chat
Stream from GPT-5.6 Sol, Claude Opus, DeepSeek, Qwen and more via CodeCraft — plus a free tier. Vision, code, long-context, all switchable mid-chat.
2 Agent Mode
Give it a goal with /agent. It plans, calls tools for up to 12 rounds, keeps running in the background with notification controls, and reports back.
3 Image & 3D
Generate images and 3D models directly in chat, with a free generation lane and premium lanes for Plus members.
4 Web & Plugins
Web search, weather, and on-device compute ship connected by default — plus a marketplace of skills you can toggle on per chat.
Unlock the premium lane
Plus opens the premium model tier — Claude Opus, GPT-5.6 Pro reasoning, and premium 3D generation lanes. Granted instantly and picked up live by the app.
How people use it
“Text me when it's done”
Kick off an agent, lock the phone, and it keeps working — a foreground service keeps the run alive with pause / stop in your notification shade.
“Search it and summarize it”
Web Search is connected by default: ask a question and it searches, reads the results, and answers with sources — no tab switching.
“Let's talk it through”
Tap the mic and speak instead of type — live transcription with hands-free spoken replies wherever you are.
