Transcription is only the first step. Here's how to transform your raw text into actionable content:

Newsletter Automation#

You have 45 minutes of transcribed podcast. Instead of spending 3 hours writing a newsletter, use AI to automatically structure your content:

Concrete steps:

1. Divide the transcription into thematic sections
2. Generate 3-4 newsletters with different angles
3. Add compelling opening hooks
4. Integrate natural CTAs

Yeemel automates this process: you paste your transcription, and 4 professional newsletters are generated in 2 minutes.

Content Repurposing for Blog#

From 1 transcription to 5+ pieces of content:

• Main blog article: structure the transcription with H2/H3
• 5 LinkedIn posts: extract the best quotes
• Twitter thread: transform key points into tweet series
• FAQ: identify questions addressed
• PDF checklist: compile advice into lead magnet

Subtitle Creation#

Transform your transcription into subtitles for your videos:

Required SRT format:

1 00:00:01,000 --> 00:00:04,000 Hi! Today we're talking about transcription. 2 00:00:04,000 --> 00:00:08,000 The first method is OpenAI's Whisper.
