Substack will let you listen to some posts. It will not let you listen to all of them, and it will not do it from the website. That gap is why this search exists.
If you just want the play button on a single English-language post, start in the Substack iOS or Android app. If you want every Substack you subscribe to — plus Beehiiv, Ghost, and the random sender who still uses Mailchimp — to show up as a daily podcast, that is a different product. This guide maps both jobs, honestly.
The four ways, in the order people actually try them
- Substack's own text-to-speech. A play icon on the post, inside the Substack app.
- The author's recorded voiceover. Rare, and usually the best listen when it exists.
- A browser reader or extension. One page, one session, usually on desktop.
- A newsletter podcast app. Your inbox becomes tomorrow morning's episode.
They are not competitors in the abstract. They cover different amounts of your unread pile.
Method 1: Substack's built-in text-to-speech
Substack documents this clearly. Open a post in the mobile app, tap the play icon at the top right, and narration starts in the in-app player. Audio keeps going in the background unless you fully close the app.
Three limits, straight from Substack:
- App only. There is no read-aloud on the Substack website.
- English only.
- Most publications, not all. If a publication is not in the rollout, tapping play tells you the post has no audio. Writers cannot switch the feature on themselves.
Creators who do have it can pick a voice in the website editor. Listeners cannot.
Good for: one English post, on your phone, from a publication that has the play icon.
The catch: it is a reader button, not a podcast habit. There is no daily queue of everything that arrived overnight, no mix of non-Substack senders, and no lock-screen player for the whole inbox. If the icon is missing, this method is over.
Method 2: Author voiceovers
Some writers record themselves. Substack treats that recording as the audio for the post, and it overrides automatic TTS when both exist. Substack's own guide to adding a voiceover is for publishers, not listeners.
Good for: the handful of writers who actually record.
The catch: most do not. Searching "listen to Substack" and hoping every issue has a human voiceover is how you end up back at the play icon, or without one.
Method 3: A browser reader, one post at a time
On desktop, Substack gives you nothing. Extensions such as CastReader fill that hole: open the post, click, listen to the article body. Speechify and similar readers do the same job if you already live in them. Edge's built-in Read Aloud works on a page you have already opened.
Good for: the one long post you have on screen right now, especially on a laptop.
The catch: you still picked the item. Tomorrow's five Substacks, two Beehiivs, and a company memo are still sitting in email. Paid posts also have to be unlocked in your own browser session first; a reader will not bypass a paywall.
This is the same shape as any general TTS tool. We wrote out the difference between that pattern and a subscription podcast in Junco vs Speechify and Junco vs Audioread.
Method 4: Turn the inbox into a daily podcast
This is what Junco is for.
Substack issues are emails. So is almost every other newsletter you pay attention to. Connect Gmail (read-only) or subscribe senders to the personal address you get at signup (you@listen.tryjunco.com), and each morning Junco turns what arrived overnight into a short episode. Queue, lock-screen controls, background playback, offline narration on your iPhone, mixtapes if the walk is long.
You do not need the writer to enable TTS. You do not need the post to be in English inside Substack's rollout. You do not copy-paste.
Good for: "I subscribe to a bunch of Substacks and other newsletters and I never get through them."
The catch: Junco is iOS. It summarizes into a short daily listen rather than reading every paragraph of a 4,000-word essay at full length. If you want the full text of one post, use Method 1 or 3 for that piece, then come back to the inbox-wide habit for the rest.
Which method to use
| Substack app TTS | Author voiceover | Browser reader | Junco | |
|---|---|---|---|---|
| Where it works | Substack iOS/Android app | Substack app / web player | Desktop (and some mobile browsers) | iOS |
| One post you have open | Yes, if the play icon exists | Yes, if the writer recorded | Yes | Yes, if that sender is in your sources |
| Every Substack you subscribe to | No, per post, and not every pub | Only the ones who record | No, per page | Yes |
| Non-Substack newsletters | No | No | Only if you open each one | Yes |
| Daily episode of what is new | No | No | No | Yes |
| Offline / lock screen / commute | Background in the Substack app | Same | Poor in a car | Built for that |
If the play icon is there and you only care about that post, tap it. If you care about the pile, skip the per-item tools.

FAQs
Does Substack have text-to-speech?
Yes, in the mobile app, for English posts, on most publications. It is not on the website, and Substack has not published a timeline for every publication.
How do I listen to a Substack post as a podcast?
If the writer recorded a voiceover, play that. If not, use Substack's in-app TTS for that one post, or forward the issue (or connect the inbox it lands in) to a newsletter-audio app so it becomes an episode in a real player.
Can I listen to Substack on desktop?
Not with Substack's own TTS. Use a browser reader on the open post, or listen later in an iOS podcast app that already ingested the email.
Does this work for paid Substacks?
If you are already subscribed, the issue arrives as email like any other paid newsletter, and Junco can turn that email into audio. A browser extension only reads text already visible in your session; it does not unlock a paywall.
Do I have to connect Gmail?
No. Junco gives you a personal inbox address at signup.
Is it free?
Junco gives new accounts 3 sample episodes, then a 7-day free trial of Junco Plus before $3.99 a month. Substack's in-app TTS is included with the Substack app.
The play button on a Substack post is a good feature when it is there. It is not a system for keeping up. Download Junco if the actual problem is the pile.
