Overview

The LMA web UI is a React application hosted on Amazon S3 and served via Amazon CloudFront. Authentication is handled by Amazon Cognito, which manages user sign-up, sign-in, and access control. The UI provides real-time meeting transcription, an AI-powered chat assistant, meeting management, and administrative configuration.

Deployment Info

• Stack name, build date, and version information

Meeting List / Dashboard

The meeting list provides a searchable dashboard of all meetings you have access to.

• Columns: Meeting Topic, Date/Time, Duration, Status, Owner, Shared With
• Status indicators: In Progress, Ended
• Multi-select: Check multiple meetings for batch operations (share, delete)
• Configurable time period: Adjust the time range for loading meetings to manage performance with large meeting histories

Use the search bar to filter meetings by topic or other attributes.

Meeting Detail Page

Clicking a meeting from the list opens the meeting detail page, which contains several panels and sections.

Transcript Panel

Real-time transcription displayed with:

• Speaker names and timestamps for each segment
• Sentiment indicators per segment
• Color-coded entries by channel for easy visual distinction between speakers

Chat Panel

Interact with the meeting assistant by typing questions or requests:

• Real-time token streaming responses from the Strands agent
• Chat shortcut buttons for common actions: Summary, Action Items, Topic, and more
• Shortcut buttons re-appear after each response for quick follow-up actions

Summary Section

• On-demand summaries generated during the meeting
• Post-meeting summaries generated automatically when the meeting ends
• Multiple sections based on configured prompt templates
• Copy to clipboard support for easy sharing

Audio Playback

When recording is enabled, a WAV recording player is available for audio playback of the meeting.

VNC Viewer

When a Virtual Participant (VP) is active, a real-time VNC viewer displays the VP’s browser view. This allows you to see and control what the VP sees in the meeting.

Meeting Metadata

Displays detailed meeting information including:

• Call ID, status, and duration
• Participants list
• Owner and shared users
• TTL (time-to-live) expiration

Sentiment Analysis

LMA provides sentiment analysis at multiple levels:

• Per-segment indicators — Each transcript segment displays a sentiment indicator
• Overall sentiment per channel — Aggregated sentiment for each speaker/channel
• Sentiment trend visualization — Track how sentiment changes over the course of the meeting

Transcript Downloads

• XLSX — Spreadsheet format with structured columns

All export formats include speaker attribution and timestamps for each segment.
