FAQ
Which browsers are supported?
Tubelight runs in any modern browser. Sign-in uses Google accounts via Firebase.
Are my documents private?
Yes. PDFs are stored per-user in Google Cloud Storage and Firestore, and every endpoint checks ownership.
Where does the AI run?
The backend runs on Google Cloud — Gemini Flash powers the LLMs and embeddings, and image generation uses Stability or OpenAI providers.
