About this tool
Draft a podcast episode description from your notes, then check it against platform character limits, chapter rules and keyword placement.
A podcast episode description is the block of text that has to sell the episode in a list view and stay findable in search, and this writer assembles one from your notes in a fixed order: summary first, then takeaways, chapters, links and a call to action. It then checks the result against the 4,000-character description limit used by Apple Podcasts and Spotify, the 5,000-character limit on a YouTube description, the YouTube chapter rules, and whether your focus phrase lands in the opening text a listener actually sees. Aimed at independent podcasters publishing to several platforms from one set of show notes.

Summary, takeaways, chapters, links, call to action — the order search and listeners both read best.
4,000 characters for Apple Podcasts and Spotify, 5,000 for YouTube, checked live as you type.
Timestamps are parsed and tested against the rules that decide whether chapters appear at all.
Aim for 200 to 800 characters of real summary before the links and chapters. The hard ceiling is 4,000 characters on Apple Podcasts and Spotify and 5,000 on YouTube, but most apps only show around the first 150 characters before a 'more' tap, so the opening sentence carries the most weight.
The first timestamp must be 00:00, there must be at least three timestamps in ascending order, and each chapter must run for at least 10 seconds. If any of those fails, YouTube silently shows no chapters at all.
In the first sentence, phrased the way someone would say it out loud. Repetition beyond two or three natural mentions does not help and reads badly to a human, which matters more here because the description is short enough to be read in full.
Yes, but below the summary. A description that opens with a URL wastes the preview space that decides whether anyone presses play, and some directories strip or linkify markup differently, so keep plain text near the top.
