I Built an AI Meeting Summarizer with Spring AI — Here's How (and Why)

Description and use

The tool automatically converts a meeting audio file into a structured summary with title, overview, decisions, action items, and next steps, using Spring AI, Whisper, and AssemblyAI.

Problem

After a productive meeting, participants forget who is responsible for action items and unresolved issues.

Outcome

The tool produces a concise, professional meeting summary with actionable items, speaker attribution, and next steps, all within seconds of uploading an audio file.

Workflow

• Upload MP3 to REST endpoint
• Transcribe audio with OpenAI Whisper via Spring AI
• Upload audio to AssemblyAI for speaker diarization
• Retrieve speaker-labeled transcript
• Generate summary with GPT-4o-mini using a custom prompt
• Return structured summary to client

Evidence

The best part? It works with any audio file — upload an MP3, and get a structured summary in seconds.
