Your newsletter issue, as a conversation.
Cohosted turns each issue into a short podcast episode for two voices: a host asks, a guest walks through your ideas and credits them to you. It's ready before you publish, and you read every line before anyone hears it.
Welcome. The voices you're hearing are synthetic, and the ideas come from Ana Ruiz, in this week's issue of her newsletter.
Ana opens with a drawer of notebooks she started and never finished. Eleven of them, by her count.
Eleven! So, for her, notebooks don't work?
She argues the opposite. In her view, writing the page is where the thinking happens. Rereading it later is a bonus, not the reason.
So the drawer isn't a graveyard.
Not for Ana. She calls it a record of thinking that already did its job.
Not a generic AI podcast
Most AI podcasts paraphrase whatever you give them. Cohosted stays on your text and leaves the decisions to you.
- The ideas stay yours. Every line is checked against your issue before you see it, and your ideas are credited to you by name.
- The voices are declared. They are synthetic and generic, no voice is cloned, and the episode says so in its first line.
- Nothing goes out without you. Cohosted never publishes anything. You decide if and where the episode appears.
- Your issues stay private. Drafts and paid issues are used only to make your episode, never shared, and deleted when you ask.
How the free month works
- Once, add a rule to your inbox that forwards your newsletter's test email to me.It takes five minutes, and I'll walk you through it.
- Send yourself a test a few hours before you publish, as you already do. A private review page arrives where the text follows the audio.
- Approve it, or tap a wrong line and say what to fix. You get a new version.
- Download the MP3 and upload it to your Substack post as audio before you publish. Readers press play right in the post.Paid issues work the same way, and the audio stays behind your paywall. Any platform that accepts an MP3 works too.
Try it free for a month
I'm looking for 8 to 10 newsletter writers: one episode for every issue you publish this month. Send me an issue you'd like to hear, and I'll send back the episode.
No account and no card.
