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.

How do I get support?

Use the support form to send us a message — we reply to every message.

How do I publish a story to Instagram or YouTube?

Generate a story, open it, and choose Share to Instagram (a carousel) or Share to YouTube Shorts (a vertical 9:16 video). You'll connect your account the first time, then confirm the slides before anything is published — we never post without your action.
