And if we don't, there's a real human at the bottom of this page who will.
Little Vox is a Mac app that takes audiobook files and gets them onto your child's Yoto player — without you needing to know anything about audio formats, file conversion, or Yoto's API. Drop in a file, click send, done.
It also has a Storybook mode, which lets grandparents, parents, and anyone with a voice record personal stories directly for your child's Yoto. No app required on their end — just a link and a tap.
Just three things:
No subscription. No cloud account. No command line. (We specifically built it so you'd never have to see a command line.)
It's four steps, and step four is basically just waiting:
When it's done, open the Yoto app on your phone → Library → Playlists. Your book will be there waiting, chapters and cover art included.
For Audiobook Mode, yes — you'll need a Yoto player to receive the uploads. But Storybook Mode works completely standalone. Record family stories, save them, share them as audio files — no Yoto hardware required.
If you're Yoto-curious, check them out here ↗ — they make a genuinely lovely screen-free player for kids.
Pretty much everything you're likely to have:
M4B MP3 FLAC M4A AAC WAV OGG
M4B is the gold standard audiobook format and gives you the best experience — chapters, cover art, and bookmarks all come along for the ride. But if you've got a folder of MP3s, that works great too.
Absolutely. Drag the whole folder onto Little Vox. It'll figure out the correct order using track numbers or filenames, stitch everything together, and treat it as a single audiobook. This is actually the most common format for MP3 audiobooks from libraries and online stores.
Not directly — Audible files are DRM-protected, which means only Audible's own apps can read them. This isn't a Little Vox limitation; it's Audible's design. We're not going to pretend otherwise.
The good news: there are excellent sources for DRM-free audiobooks that work perfectly:
Quite a lot, actually — it's just very good at hiding it. When you hit "Send to Yoto," Little Vox reads your file's metadata, re-encodes the audio to Yoto's exact specifications, splits it into chapters for card navigation, sorts out the cover art, and uploads everything directly to your Yoto library via the same API the official Yoto app uses.
The part we're most proud of: all of the heavy processing runs entirely on your Mac. Your audio files never touch our servers — they go straight from your computer to Yoto. This is why we can charge a one-time price with no ongoing fees. Your Mac does the work, not ours.
A typical 10-hour audiobook takes 2–5 minutes on a modern Mac. You can queue up multiple books and walk away — Little Vox will work through them while you do something more interesting.
No. Little Vox re-encodes to Yoto's required format at a quality level optimized for spoken word audio. For audiobooks and voice recordings — which is all we're dealing with here — the result is indistinguishable from the original at any normal listening volume.
If your file is already in the right format, Little Vox is smart enough to skip unnecessary steps. We're not re-encoding things that don't need it.
Only for two things: uploading to Yoto, and browsing the Internet Archive. The audio conversion itself is entirely offline — Little Vox processes everything locally, so it works on a plane, in a cabin, wherever you have your Mac.
Storybook Mode lets you — or anyone you invite — record a personal story or message for a child's Yoto. You create a story in Little Vox, send a link to your narrator (grandma, grandpa, anyone), and they record directly in their browser. No app, no account, no technical setup on their end.
When they're done, Little Vox notifies you, processes the recording, and it's ready to send to Yoto. Grandma's voice, on their Yoto, forever. 💜
Nope. They tap the link, press record, tell a story. Works in any modern browser on a phone, tablet, or laptop. If your narrator can send a text message, they can record a Storybook.
Yes — the recording page supports multiple chapters. They can record chapter one today, come back tomorrow for chapter two, and Little Vox keeps it all organized. Recording links stay active for 7 days, and any in-progress recording is saved automatically so nothing gets lost if they close the tab.
Free users get 5 Storybook recordings. The $29.99 lifetime license unlocks unlimited recordings, along with one-touch auto-upload to Yoto and everything we build next.
Given that the average streaming subscription costs more per month than Little Vox costs forever, we think it's a pretty good deal.
Technically, yes. Yoto does let you upload your own audio and record stories directly in their app. But "technically possible" and "actually pleasant to do" are very different things.
Uploading your own audiobooks: Yoto's native upload has strict requirements — specific audio formats, file size limits, track length limits, and a fiddly manual process for getting chapter structure right. Miss any of it and the upload fails, or your book lands on the player in a mess. Getting a full audiobook on there the hard way takes real effort and a fair amount of Googling.
Recording personal stories: Yoto's built-in recording feature is tucked away in the app and assumes you already know where to find it. If you want Grandma to record a bedtime story, you're asking her to download an app, create an account, navigate a menu that wasn't designed with her in mind, and figure it out — all before she's said a single word. Most grandmas give up before they get started. (Most parents do too, honestly.)
Little Vox makes both of these completely effortless:
$29.99 — one time, forever. No subscription, no renewal, no "we're changing our pricing model" email in 18 months. You pay once, you own it.
Free forever: Full audio conversion, the Internet Archive browser with unlimited downloads, 5 Storybook recordings, and 5 ClearVox books. You get a lot before paying a penny.
$29.99 license unlocks:
One license covers one Mac. If you get a new computer, just email us — we'll sort it out. We're not going to be weird about it.
No. Your audio files are processed entirely on your Mac, then sent directly to Yoto's servers. Little Vox never sees them, touches them, or stores them. We built it this way on purpose — it's better for your privacy, and frankly, storing everyone's audiobooks would cost us a fortune.
Your Yoto credentials are stored using macOS's encrypted system storage — the same technology that protects your passwords and banking details. They never leave your Mac and are never transmitted to our servers.
As little as possible:
Full details in our Privacy Policy — written by humans, not lawyers trying to obscure things.
Yoto occasionally takes a minute or two to index new content. Open the Yoto app, pull down to refresh, then tap Library → Playlists. Give it a moment.
Still nothing? Tap "Disconnect" in Little Vox and reconnect your Yoto account. That usually does it.
First, try the "Try Again" button — sometimes files are grumpy on the first attempt. If it fails again, your file might be in a format Little Vox can't read.
The fix: convert it to MP3 first using a free tool like VLC (File → Convert), then drag the MP3 into Little Vox. Works 99% of the time.
Little Vox handles files up to 4 GB, which covers virtually every audiobook out there. If you're hitting the limit, your file is probably a lossless recording (FLAC or WAV). Convert it to MP3 first — it'll be a fraction of the size with no noticeable quality difference for spoken word audio.
Recording links expire after 7 days. In Little Vox, find the story, tap the "..." menu, and select "Create new link" — it'll send a fresh one with all the details pre-filled. Easy.
We're a small team, which means when you email us, a real person reads it and writes back. No support ticket queue, no chatbot, no "have you tried turning it off and on again" auto-reply.
