Goes and looks. Leaves nothing behind.
Where it searches
| Source | What it brings |
|---|
| Research | Open-access papers from OpenAlex, Europe PMC and Crossref |
| Web | A search chain read through a private browser |
| Recent | Fresh news coverage |
| Context | Wikipedia |
How a search works
- Your question is broken into searches.
- Celina reads the pages it finds and checks for gaps.
- It writes an answer and cites each claim.
- Every citation is checked against text it actually retrieved.
- Disagreement and missing evidence are stated plainly.
What you can watch
- A live trace of every search, page, filter and failure.
- A traffic list of every network request Celina makes.
- A token meter showing what each step used.
What it keeps
| Kind | What happens to it |
|---|
| Kept work | Saved to your library on your computer, until you delete it |
| Session traffic | Deleted when you end the session |
| Incognito session | Deleted when ended, when the page closes or on restart |
| Old sessions | Expire after 24 hours by default |
Model choices
| Provider | Notes |
|---|
| Anthropic | Your key |
| OpenAI | Your key |
| OpenRouter | One key, many open models |
| xAI | Your key |
| Ollama | Runs on your machine. Nothing leaves it |
What it does not do
- Hide your IP address. Use your own VPN if you need that.
- Log in to social platforms as you.
- Send notifications, streaks or badges to pull you back.
- Run a cloud service, accounts or telemetry.
You will need
- Windows with the WebView2 runtime (included with Windows 11).
- A model key, or Ollama running locally.
- The tester build is unsigned, so Windows may warn you.
