Generate podcast show notes and timestamps with WayinVideo and GPT-4o-mini

Description

Submit any podcast episode recording URL along with the episode number, podcast name, host name, episode topic, niche, and CTA link — and optionally a guest name and title if it is an interview episode — and the workflow transcribes and analyzes the full episode automatically. WayinVideo's Transcription API returns a speaker-labeled, timestamped transcript which GPT-4o-mini reads to write eight labeled show notes sections — episode title, SEO description, key takeaways, resources mentioned, timestamped highlights, guest bio, CTA block, and a fully compiled show notes document ready to paste. The GPT prompt adapts automatically for interview episodes versus solo episodes based on whether you provided a guest name. Everything is saved to Google Sheets as one row with Status set to Draft — ready to copy directly into Spotify for Podcasters, Apple Podcasts, or your episode page. Built for podcast producers, solo hosts, and content teams who spend 30–60 minutes per episode writing show notes manually.

What This Workflow Does

- Transcribes the full episode with speaker labels and timestamps — [WayinVideo](https://wayin.ai/api/) returns every spoken word with the speaker name and MM:SS timestamp so GPT can extract highlights and quotes from the actual episode content - Detects interview vs solo format automatically — If you provide a guest name in the form, the prompt adapts to write a guest bio and frame the show notes as an interview — if you leave it blank, it treats the episode as solo - Generates a compiled FULLSHOWNOTES section — All eight sections are assembled into one complete, copy-paste-ready show notes document — the full block is saved in its own column so you can paste it directly into Spotify, Apple, or a website without reassembling it manually - Extracts timestamped highlights from the actual transcript — GPT picks 6–8 of the most interesting moments from the episode using exact MM:SS timestamps from the transcript — not approximate or invented times - Writes an SEO episode description with keyword in the first sentence — The 150–200 word description follows podcast platform SEO best practice so your episode is discoverable in search - Logs only real resources mentioned in the episode — GPT is instructed to extract only resources, links, or tools that were explicitly named in the recording — no invented or generic resources - Saves 19 fields per episode to Google Sheets — All eight content sections plus episode metadata, word count, duration, recording URL, and CTA link are saved in one row per episode
