ACX Alternatives: Findaway, Spotify, Apple, and More

ACX is no longer the obvious default. In 2026 Audible moved every title onto a pooled, listening-based royalty model, and its upload rules still turn away third-party AI narration. If either of those breaks your plan, these are the ACX alternatives that actually move audiobooks, with the terms as they stand in October 2026.

The short answer

If your narration is AI, skip the ACX upload and go wide through Voices by INaudio or Authors Republic, then add Kobo, Google Play and direct sales. If your narration is human and Audible is where your readers live, ACX exclusive at 50% can still be the right call.

Why authors look past ACX now

Three changes in 2026 pushed a lot of indie authors to read the fine print again.

1

The royalty became a pool

Audible opened its new royalty model to every ACX creator on May 26, 2026. Rates went up, from 40% to 50% for exclusive titles and from 25% to 30% for non-exclusive ones, but the base changed. Instead of a cut of each sale, a listener's monthly plan value is split across the titles they listened to, weighted by each title's price, and your share is multiplied by your rate. A higher percentage of a pool is not the same as a higher payout, and nobody can tell you in advance which one you get.

2

The old model has an end date

Titles claimed after May 26 are enrolled in the new model automatically. Existing titles keep the legacy 40% and 25% only until the end of 2026, when Audible discontinues it. By then you either enroll or pull the title from Audible. Audible also sets the final price; you can suggest one.

3

Uploads must still be human-narrated

ACX's submission requirements say audiobooks must be narrated by a human unless otherwise authorized. Amazon's own AI route, Virtual Voice, is a KDP program that narrates your ebook with Amazon's voices. Audio you produced elsewhere with AI cannot go through a normal ACX upload.

None of this makes ACX bad. It makes it one option among several, and the others are now good enough that the decision deserves ten minutes. If you have never been through ACX itself, our ACX walkthrough for Audible covers the upload flow and the audio spec in detail.

Each platform in plain terms

Voices by INaudio (formerly Findaway Voices)

Findaway Voices became Findaway Voices by Spotify, and in August 2025 its original founders bought it back and relaunched it as an independent company, Voices by INaudio. The deal is simple: no upfront fee, non-exclusive, and you keep 80% of what the retailers pay it. On Spotify sales the distribution fee is waived, so the whole Spotify royalty is yours. One upload reaches Apple Books, Google Play, Kobo, Spotify, Chirp and library apps such as OverDrive and Hoopla. If you search for Findaway Voices today, this is where you end up.

Authors Republic

Authors Republic is the other big non-exclusive aggregator. It pays authors 80% of earned royalties and lists Audible, Apple, Spotify, Google Play, Hoopla and Libby among its channels. It is also one of the two routes into Chirp, BookBub's audiobook deal store. Disclose AI narration at upload and expect the occasional retailer to decline it. Some authors use INaudio for most stores and Authors Republic for a channel INaudio does not reach; just never send the same title to the same store twice.

Spotify for Authors

Spotify is now a real audiobook store, with listening hours included in Premium plans and an Audiobooks+ add-on for heavier listeners. It accepts disclosed AI narration, and named ElevenLabs voices specifically when it opened the door. In May 2026 it announced its own ElevenLabs-powered creation tool inside Spotify for Authors, launching as an invite-only, English-only beta in June. For most indies the cleanest route into Spotify is still an aggregator, and through INaudio that route costs no fee.

Kobo Writing Life audio

Kobo takes audiobooks directly through Kobo Writing Life, free and non-exclusive. The terms most authors work from: 45% of list price on purchases at $2.99 and above and 32% on paid subscription downloads. AI narration is allowed, but the narrator contributor must read Synthesized Voice, Female Synthesized Voice or Male Synthesized Voice. Kobo is strongest in Canada and parts of Europe, so it matters most for books with readers there. The ebook side of the same decision is in our KDP vs Kobo comparison.

Google Play Books (upload or auto-narration)

Google Play does two separate things. You can upload finished audio like any store. Or, if your ebook is already on Google Play, you can generate a free auto-narrated edition in its beta program, choose a voice and fix pronunciations. You can then download that audiobook as numbered MP3 files and sell it elsewhere, as long as it stays on sale on Google Play in those countries and the Google Play price is not higher than anywhere else.

Apple Books digital narration

Apple narrates eligible English ebooks for free through its preferred partners, Draft2Digital for independent authors and PublishDrive. The ebook has to be on Apple Books and you must own the audio rights. Apple's own page says the author keeps the audiobook rights and can produce and distribute other versions. You get no files to take elsewhere, so treat it as a free Apple-only edition, not a master copy.

Direct sales with BookFunnel

Selling direct means your own store (Shopify, Payhip or a WordPress shop) takes the payment and BookFunnel delivers the audio, either as a download or through its own listening app with chapters, bookmarks and speed control. You set the price, keep almost all of it, and learn who your listeners are. It pays off when you already have readers who open your emails, and it pairs well with a reader list on an AIWriteBook author page.

Pick your route

The routes split four ways: an aggregator, a store you upload to yourself, a store that narrates for you, and your own shop. Most wide authors use two or three at once.

Going wide, step by step

Here is the order that avoids the most rework, assuming you already have mastered files.

  1. 1. Confirm you hold the audio rights

    If a narrator worked on royalty share through ACX, that title is tied to ACX. Check any publishing contract for an audio clause too.

  2. 2. Pick one aggregator as your backbone

    INaudio or Authors Republic, not both for the same store. Note which stores you plan to cover yourself and leave them unticked in the aggregator.

  3. 3. Prepare one clean set of files

    Chapter MP3s, opening and closing credits, a retail sample, and a square cover of at least 2400 by 2400 pixels. Mastering to the ACX spec (RMS between -23 and -18 dB, peaks no higher than -3 dB) is the safe target, because every store on this list accepts it.

  4. 4. Write metadata once, reuse it everywhere

    Same title, subtitle, series name and description in every store. Declare AI narration in the narrator field and the description where the store asks.

  5. 5. Add direct stores and direct sales

    Kobo Writing Life and Google Play if you upload them yourself, then a BookFunnel delivery link on your own shop.

  6. 6. Price for the market, then promote

    Keep prices consistent so no retailer price-matches you down. Once the title is on Chirp, it can be submitted for a Chirp deal, which works like a BookBub Featured Deal for audio.

Audiobook Studio

Need the audio before you need the distributor?

Turn a book you wrote or imported into a narrated, mastered audiobook, chapter by chapter, and export the files the platforms above ask for.

Mistakes that cost royalties

Sending the same title to one store twice

INaudio and Authors Republic both deliver to Apple and Google. Two feeds of one audiobook create duplicate listings and tangled reports. Split stores between them deliberately.

Hiding the AI narration

Every platform that accepts AI narration asks you to disclose it. Leaving it out is the quickest way to have a title removed and an account flagged.

Assuming 50% beats 80%

50% of a pooled member value and 80% of a retailer's net payout are different bases. Compare what one listener is worth on each route, not the headline percentage.

Mistaking Google's auto-narration for a master

You can download it, but it must stay on sale on Google Play wherever you sell it, at a price no higher there than anywhere else. If you want files with no strings, produce your own.

Forgetting libraries

OverDrive and Hoopla reach listeners who never buy audiobooks at retail. Only the wide aggregators get you there, and ACX exclusive shuts that door.

The AI-assisted shortcut

Distribution is the easy half. The hard half is a finished, listenable recording, which used to mean weeks of work and a narrator invoice in the thousands.

The Audiobook Studio in AIWriteBook narrates the book straight from the chapters in your editor. You pick a narrator from 25 voices, the studio casts a separate voice for each character if you want one, and chapters render one at a time so you can listen as you go. A mispronounced name gets respelled and re-recorded on its own, without redoing the chapter.

Exports come out mastered to a retail target of -19 LUFS or a streaming target of -14 LUFS, at 128, 192 or 256 kbps: a merged MP3 with a chapter-markers file, a ZIP of numbered chapter MP3s for aggregators, or an M4B with chapters and cover art for direct sales. Every voice is an ElevenLabs voice, the kind Spotify explicitly accepts with disclosure. The audiobook generator feature page has full samples and credit costs.

Questions authors ask

The bottom line

ACX is still the biggest single audiobook store, and for a human-narrated book whose readers live on Audible, exclusive at 50% is a defensible choice. For everyone else, and for every AI-narrated edition, the better default in 2026 is wide: one aggregator as the backbone, Kobo and Google Play where they matter, and direct sales to the readers you already have.

Audio is one branch of the Amazon publishing path; our Amazon KDP guide maps the rest of it.
