~15 min read + 10 min hands-on

1 Why this tool matters

AssemblyAI is a speech-to-text API with a no-code playground. Upload an audio or video file; get back a transcript, a summary, key chapters, sentiment, and speaker labels. For anyone who attends meetings, interviews, or lectures, this is quietly life-changing.

2 Walkthrough

  1. Go to assemblyai.com/playground. Sign up — the free tier is ample.
  2. Upload any audio file you have: a recorded meeting, a voice memo, a podcast.
  3. Turn on Speaker Diarization and Auto Chapters before transcribing.
  4. Review the results: you will get a clean transcript, with speaker tags and chapter breaks.
  5. Copy the summary into your notes app. Save 20 minutes you would have spent re-listening.

3 Your turn

Today’s exercise

Record a 3-minute voice memo of yourself thinking out loud about one work problem. Upload to AssemblyAI. Read the transcript back. Notice what you actually thought vs. what you remembered thinking.

4 Pro tip

Worth keeping

For Zoom meetings, the cleanest workflow is: record locally → upload to AssemblyAI → save the transcript next to your notes. In a few weeks you will have a searchable archive of every meeting you cared about.
