Turn a Substack archive into an audiobook in one afternoon.
You've got 50 essays, the kind that take 4-6 minutes each to read, and people keep asking for an audio version. Until recently the answer was: book a studio, hire a narrator, mix in Pro Tools, master to ACX. Or just don't.
Here's how to do it on Artistik in the span of an espresso and a walk around the block.
The five steps
- Export your Substack archive. Settings → Exports → Download. You'll get a ZIP with one HTML file per post. Pick the 20–30 essays you want in the audiobook. Concatenate them into a single document — Pages, Word, anything. Add a quick foreword and a one-paragraph intro per essay. Rough word count after pruning: 30k–60k.
- Open the studio and create an Audiobook job. Drop the document into the upload zone. Artistik extracts the text — no copy-paste, no formatting drift.
- Pick a voice. The agent presents 4–6 ElevenLabs voices that match your tone brief (warm and conversational? newsroom-precise? story-time intimate?). Each plays a 5-second sample. Confirm the one you want.
- Walk away. The agent renders chapter by chapter, watches loudness, retries any clip that comes out muddy. You get an email when the full-book MP3 is ready.
- Ship it. Upload the MP3 to ACX, Findaway Voices, Apple Books, or just drop it in your Substack as a paid-tier perk.
What it costs
ElevenLabs is the only meaningful cost — about $0.00012 per character. A 50k-word essay collection is roughly 280k characters, so the raw API cost lands around $33. With Artistik's 1.4× Pro markup, you're paying about $46. Plus an EPUB pass if you want the text edition too.
That's a tenth of what a human narration session costs, and you can iterate — try a different voice, try a different pacing — without booking another studio day.
What it doesn't do
Some things still need human judgment:
- Pronunciation of names and proper nouns. ElevenLabs gets it right ~95% of the time. The other 5% you'll catch on a listen-through and re-render the affected line.
- Emotional inflection on a punchline. The narration is good, but it's not Audible-narrator-of-the-year good.
- Music + sound design. Out of scope for the audiobook agent — drop the MP3 into a DAW if you want bumpers.
