## Overview

ByteBrains Translator is a Streamlit app for translating text, documents, audio, and image text. Users choose a modality, languages, and an AI model; the app handles modality-specific extraction or conversion, requests translation, and presents the result. The main UI and most modality logic live together in app.py, which also owns authentication and theme controls. Source excerpts show image translation calling the SambaNova helper and Google user-info lookup; other modality capabilities are documented in the README, but their detailed call paths were not sampled.

Main entry points: [`app.py`](https://github.com/zenhakp/bytebrains-ai-translator/blob/main/app.py) (Streamlit interface), [`sambanova_agent.py`](https://github.com/zenhakp/bytebrains-ai-translator/blob/main/sambanova_agent.py) (SambaNova translator)
