Podcast Show Notes Generator

Show notes are the chore standing between every finished recording and a published episode. Writing them by hand means re-listening to the whole episode, scrubbing for the moments worth mentioning, summarising the conversation, hunting down every book and link the guest brought up, and formatting it all for your host. For a weekly show that's 1-2 hours of work, every single week — which is why so many episodes ship with two thin sentences instead of real notes.

Castmagic does that work from the audio itself. Paste an episode link or upload your file, and within minutes you get a full transcript plus AI-drafted show notes: an episode summary, key topics with timestamps, a guest bio, the resources mentioned, and a sheet of pull-quotes. Everything is grounded in the transcript, so the notes describe what was actually said — then you review, tweak, and paste them into your podcast host.

Why show notes matter (and why nobody enjoys writing them)

Show notes do real work for a podcast. They tell prospective listeners whether an episode is worth their time, they're the only part of an episode search engines can read, and they're where guests, sponsors, and resources get their links. Apple Podcasts and Spotify both surface episode descriptions prominently — an episode with two vague sentences underneath it is leaving discovery on the table.

The problem is the production cost. Good show notes require re-listening to the episode you just spent hours editing, taking notes on topics and timestamps, and writing it all up. Most podcasters either burn an evening per episode on it or skip it entirely. A show notes generator removes that trade-off: the AI does the re-listening, you do the judgement.

What Castmagic puts in your show notes

Every episode you run through Castmagic produces a complete show-notes package: a 2-3 paragraph episode summary, a list of key topics with timestamps, a guest bio built from how the guest was introduced and what they discussed, the resources mentioned — books, tools, links, other shows — and a set of pull-quotes for promotion. You also get the full transcript with speaker labels, downloadable as TXT, PDF, DOCX, SRT, VTT, or CSV.

If your show has a house format — a specific order of sections, a sign-off line, a sponsor block — you can edit the draft into that shape, and Castmagic's other presets (titles, chapter timestamps, social posts) fill in the rest of the publishing checklist from the same transcript.

Works with every major podcast host

The generated notes are plain, portable text, so they paste cleanly into any host: Spotify for Podcasters, Apple Podcasts Connect, Libsyn, Spreaker, Buzzsprout, and the rest. Chapter timestamps come in the standard 0:00 format, so the same list also works as YouTube chapters if you publish video versions of your episodes.

Link or upload — both work

If the episode is already live, paste its URL — YouTube, Apple Podcasts, Spotify episode links, Vimeo, and most other public platforms work. If it isn't published yet (the more common case, since show notes are usually written before launch), upload the audio or video file directly. Either way the workflow is identical: transcript first, show notes drafted from it.

Names and jargon transcribe correctly

Show notes live or die on getting names right — the guest, their company, the niche tools they mention. Castmagic supports custom vocabulary: add boosted words and custom spellings so brand names, guest names, and industry jargon come out correctly in the transcript, which means they come out correctly in the notes too.
