castmagic alternatives: when there's no recording yet

the right castmagic alternatives depend on one thing: whether you already have a recording. Castmagic takes a podcast, a video, a webinar or a meeting you've recorded and turns it into a transcript, show notes, newsletters, LinkedIn posts, blog articles and clips. if you have a back catalogue, or a team producing recordings every week, it does that job well and you may not need an alternative at all.

if you don't have the recording, there's nothing for it to work on. that's the gap underway sits in. underway starts from nothing: it interviews you, out loud, about your business and what you actually did, cuts a numbered episode from your answers, and then writes the posts for every platform from your own words. we make underway, so this page says what each tool is for, from each one's own pages on 28 October 2026, and credits Castmagic where it is better.

to judge the output rather than our description of it, a real series made with underway, every episode in order, is here.

key takeaways

• Castmagic repurposes. you bring a recording, by link, file, feed or meeting, and it drafts the written and visual content around it.
• underway produces. you bring nothing but the time; it asks the questions, makes the episode, then writes the posts from what you said.
• Castmagic is the better choice for an existing podcast, a meetings archive, or a content team with several brands.
• underway is the better choice for one founder who wants a regular episode about their business and doesn't know what to say on camera.
• Castmagic starts at $19 a month billed yearly ($29 monthly). underway starts at $29.99 a month, with a 7-day free trial.

what Castmagic does well

Castmagic calls itself an AI content operating system, and the description is fair. you paste a link from YouTube, Spotify, Apple Podcasts, TikTok or Vimeo, drop in a file, connect Zoom, Loom or Google Drive, or point it at an RSS feed, and it imports the recording. with autopilot on a feed, it pulls in every new episode the morning it publishes. a few minutes later there's a speaker-labelled, timestamped transcript in any of more than 60 languages.

from that transcript it drafts a whole written set: show notes, summaries, newsletters, LinkedIn posts, blog articles, quotes, action items, meeting recaps and captions, with every item citing the moment it came from. its Studio cuts captioned vertical clips, swipeable carousels and audiograms. a content strategist suggests what to publish next from everything in your library, a chatbot on your site answers visitors' questions from your episodes, and an API lets you run the whole thing from your own systems.

it is also built for teams: multi-brand workspaces, permissions, folders and approval workflows, with five seats on its Team plan. if good recordings go out with nothing written around them, it's a strong answer.

one feature is worth singling out, because it is the closest Castmagic gets to what underway does. Asks is an interview that runs itself: you send a link to a customer, an expert, a guest or your community, they answer out loud or in writing on their own time, and the answers arrive transcribed in your library. it's a clever way to gather other people's words, but it's aimed at them, not at getting you on camera.

why people look for castmagic alternatives

the usual reasons on page one are price and fit: clips rather than text, or a tool that also records. those are fair, and the short list further down covers them. but there's a bigger reason the lists skip.

repurposing assumes the hard part is done. for a podcast with a host, a format and guests booked, it is: the show exists and the writing around it is the chore. for a founder who wants to document a business, the hard part comes first. there is no show. there's a day of work and a vague sense that it should be on camera. sitting down to record with nobody asking anything usually produces a few awkward minutes and then nothing, and without the recording, a repurposing tool has nothing to repurpose.

so the useful question when weighing castmagic alternatives isn't which one writes better show notes. it's whether you have something to feed it, or whether you need something to make the recording with you in the first place.

what underway does differently

underway starts before there's anything to record. it reads what you connect, read only: GitHub, your calendar, email you forward, Slack, your shop or payments, your website. before your first episode you film episode zero, a short interview about what you're building, who it's for and where it stands, which becomes standing context for every interview after it. so when you sit down, it already knows what you're working on.

you pick what the episode is about from topics it suggests, or type your own. it asks one question out loud for each thing you picked, in that order, and the question stays on screen. you answer for as long as it takes. on days you want to be pushed there's the AI co-host instead, a live conversation that reacts and follows up on what you say. both work on camera or by voice only, whenever suits you.

then it cuts the episode itself: filler, restarts and dead air out, cut on full sentences, captioned, your episode card on the front, and always in the order you said things. underway never moves your best line to the front of an episode, because a diary that's been reordered stops being a diary. Shorts are cut separately, when you press Find clips, to advertise the episode, and those may open on any line. the episode is numbered, so episode 47 follows episode 46, and your page lists them in order.

the posts, written from your own words

this is the part where underway overlaps with Castmagic, so it's worth being exact. every underway episode comes with the words that go around it, one set for each place it lands: a YouTube title and description, a LinkedIn post, a caption for TikTok and Instagram, an X post, and versions for Reddit, Snap, the podcast and an article. they're written from what you said in that episode, nothing invented, and you read them, change what you like and post from there. nothing goes anywhere until you press it.

each public episode also gets its own page, with the episode at the top and a written article underneath, made from what you said and checked against it. the difference from Castmagic is the input, not the writing. Castmagic writes from any recording you give it, from any show and any speaker. underway writes from the interview it ran with you, so the posts are always about your business, in your words, the same day you filmed.

which is right for you

other castmagic alternatives, briefly

if what you want is another repurposing or recording tool, these are the names that come up most. we haven't tested each one on the same day as this page, so this is what each is known for, not a ranking.

• Riverside: a remote recording studio with separate tracks for each guest, and now AI agents that prepare, edit, clip and post. from $24 a month billed yearly or $29 monthly. the right pick if you need to record guests first.
• Descript: recording and editing by the transcript in one app, with AI help for show notes. a good fit if you like doing the edit yourself.
• Opus Clip: starts from a long video you already have and cuts it into short vertical clips. clips rather than text.

every one of them, like Castmagic, starts from a recording, a guest or a video that already exists. underway is on the other side of that line.

what underway costs

every new account starts with a 7-day free trial of Founder, Series or Studio. you add a card at the start and nothing is charged until day 8; cancel before then and you pay nothing. Founder is $29.99 a month or $299.90 a year: the interview, the finished episode, Shorts when you press Find clips, the words for every platform, your page and every connection. Series is $79.99 a month or $799.90 a year and adds one tap to post to the networks you connect, the weekly round-up and the podcast feed. Studio is $129.99 a month and adds things like YouTube thumbnails with your face in them and motion graphics on your episodes. your raw recordings download on every plan.

what results look like

the clearest result we can show is our own. Rich Lovatt, who makes underway, films a numbered series about building it, with it: each episode an interview about that day's work, cut and captioned without opening an editor, with the posts written from what was said. they're on the series page in order. a series like this is one story, told while it's still happening.
