Webapp

The Streamlit GUI runs at http://localhost:8501 and provides a point-and-click interface to all summarizer features.

$
python -m streamlit run app.py

Supported Inputs

Text files bypass audio processing entirely and go straight to summarization.

Sidebar Controls

• Provider — Choose from configured providers in summarizer.yaml
• Prompt type — Select summary style from prompts.json
• Chunk size — Characters per text chunk (minimum 1000)
• Audio speed — Pre-transcription speed-up (reduces cost, may reduce accuracy)
• Language — Auto, English, Spanish, French, German, Italian, Portuguese, Chinese, Japanese, Korean
• Transcription — Cloud Whisper or Local Whisper (Whisper-based)
• Visual mode — Toggle video-direct mode

History

The sidebar keeps an in-memory history of recent summaries (last 10). Enable keep-history: true in summarizer.yaml to also persist summaries to disk so they survive page refreshes.

Mermaid Diagrams

When a summary contains ```mermaid blocks, the webapp renders them as interactive diagrams with:

• Wheel zoom — Scroll to zoom in/out
• Drag pan — Click and drag to move around
• Fullscreen — Expand to full screen
• Theme-aware — Adapts to dark/light mode

Clipboard

Copy the full summary to the system clipboard with a single button. Works in both secure and non-secure browser contexts.

Themes

Switch between Dark, Light, and System modes. The theme applies to the entire UI including Mermaid diagrams.
