Feature Overview

Everything in the box

Celestra AI ships working systems. Here is what each part does today.

1 Multi-Model Streaming Chat

Switch models mid-conversation with instant fallback if a provider fails.

  • CodeCraft catalog — 33 models: GPT-5.6 Sol / Terra / Luna, GPT-5.5 Pro, Claude Opus 4.6–5, Claude Sonnet 5, DeepSeek V4, Qwen 3.7 / 3.8, Grok 4.5, and more.
  • Free tier: xkiro free models (Qwen, Mistral, MiniMax, GLM…) — default model is Qwen 3.7 Flash.
  • 1M+ token context on long-context models, tool/function calling, and vision on supported models.
  • Image attachments are auto-stripped for non-vision models instead of failing the request.
  • Full upstream errors surface verbatim, then the router auto-switches to a fallback model.

2 Agent Mode

Hand it a goal, walk away. The agent loops until done.

  • /agent plan a trip… starts a background run; /end stops it.
  • Up to 12 tool rounds per turn — search, weather, compute, plugins.
  • Keeps running when the app is backgrounded (foreground service) with pause / resume / stop in the notification.
  • Guidance injection: send a follow-up mid-run from chat.
  • A task queue drains agent goals one after another, and completed runs land back in chat.

3 Image & 3D Generation

Generate visuals without leaving the chat.

  • AI image generation rendered inline as you stream.
  • Text → 3D models through a free generation lane; Plus members get premium lanes.
  • Progress streaming with live status, and a Stop button that actually cancels the generation.

4 Plugins & Skills

Tools the model can call, controlled by you.

  • Weather, Compute, Web Search ship connected by default.
  • Per-plugin permission prompts (Allow once / Always / Deny) with remembered choices.
  • Honest tool errors: if something isn't available, the model is told exactly that.
  • Marketplace of additional skills you can enable per chat.

5 Workspace: Chats, Artifacts, Memories

Your work is organized and stays yours.

  • Chats with titles, folders, pinning, starring — stored locally and synced to your account.
  • Artifacts: code and documents rendered as rich previews (Treasure chest for generated files).
  • Memories: facts the assistant keeps about you, memory-only — never silently pushed to the cloud.
  • Full account data export anytime; account deletion from the web (works from this site).

6 Reliability & Platform

Boring infrastructure, done right.

  • 3600s streaming timeout on every provider — long generations don't die at 30 seconds.
  • Automatic provider fallback keeps chat alive when one backend blips.
  • Silent FGS mode, no crash spam from widgets or background services.
  • Google Sign-In and email/password auth backed by Firebase.
