This is a submission for the AssemblyAI Challenge : No More Monkey Business.

What I Built

Insightview is a modern web application that streamlines the interview workflow for journalists. By leveraging AssemblyAI's LeMUR and Universal-2 technology, it transforms raw interview recordings into structured, actionable content, dramatically reducing the time from recording to publication.

Key Features:

🎥 Audio/video file upload with real-time preview
🗣️ Advanced transcription with speaker identification
⭐ Automatic highlight extraction of key moments
✍️ AI-powered article draft generation
📤 Export interview's subtitles in VTT format

Demo

Experience Insightview in action at the Live Demo. Upload your own interview recordings to see how the platform handles transcription, highlight extraction, and article generation in real-time.

Journey

Working for Italy's leading news organization, I interact daily with journalists who've expressed a common pain point: the time-consuming process of transcribing interviews and adding subtitles. When I discovered the AssemblyAI challenge, I saw an opportunity to build a solution that could transform their workflow.

Insightview was built using Next.js and TypeScript, with a clean and modern UI powered by Tailwind CSS and Shadcn UI components.
Insightview integrates AssemblyAI's technology in three powerful ways:

1. Transcription

I used AssemblyAI's Universal-2 speech-to-text model for accurate interview transcription, ensuring faithful proper nouns, precise text formatting, and casing. Advanced speaker identification and labeling are powered by LeMUR. Users can generate subtitles from the transcription and export them as a VTT file. For video uploads, subtitles are automatically added to the video preview.

2. Smart Highlights

I implemented LeMUR to automatically extract the most engaging and impactful quotes from interviews. The prompt is designed to identify powerful, insightful, or memorable segments between 5 to 15 seconds long. Each highlight is precisely linked to the original audio or video timestamp using Universal-2's accurate timestamp detection, enabling journalists to quickly preview the extracted segments.

3. Article Generation

One of the most intriguing applications of LeMUR is the article drafting feature. I crafted a sophisticated prompt that enables LeMUR to:

Grasp the interview context
Extract key highlights
Organize content in a journalistic style
Preserve the original tone and emotional nuances
Generate clean HTML with proper semantic markup

This feature isn’t meant to replace the expertise of seasoned journalists but serves as a valuable tool to inspire and accelerate their work. It provides a draft template as a starting point, allowing them to focus on refining and enhancing the final article.

Other prompts submission

This submission also qualifies for the Sophisticated Speech-to-Text prompt, showcasing Universal-2's strengths in accurate transcription, proper noun recognition, and precise timestamp detection seamlessly integrated into the application.
