Free, unlimited text-to-speech — no word limit
"Free" text-to-speech apps almost always mean "free with a cap." Shmia's free tier has no daily minutes limit, no word or character count, and no trial clock — because of how it's built. Here's the honest comparison across the field.

The free-tier limits, side by side
| App | Free-tier limit | Platform |
|---|---|---|
| Shmia | Unlimited, forever — 10 local voices | Mac + Windows desktop |
| NaturalReader | 20 minutes per day | Browser / desktop, mostly import-based |
| ElevenReader | ~10 hrs/month premium voices, no unlimited fallback | Mobile only (no Mac/Windows app) |
| Speechify | Limited free tier, no unlimited option | Mobile-first, browser extension |
| Balabolka | Unlimited, free, offline | Windows only, robotic OS voices |
Why "free" so often means "free until you hit a wall"
Most cloud-based text-to-speech products generate audio by calling an AI voice API for every request, and those API calls cost the company money per minute or per character. That cost has to come from somewhere, so the free tier gets capped — a daily minutes allowance, a monthly hours ceiling, a word count — to keep the free users from costing more than the company can absorb. NaturalReader's 20-minutes-a-day cap and ElevenReader's roughly 10-hours-a-month premium-voice ceiling are both examples of this same underlying constraint: someone is paying per minute of generated audio behind the scenes, and the limit exists to control that cost.
How Shmia's free tier is actually unlimited
Shmia's free tier works differently at a technical level, which is why the "unlimited" claim is more than a marketing line. The 10 built-in voices generate speech entirely on-device — on your own Mac or Windows computer's hardware, not through a metered cloud API call. Since there's no per-minute server cost tied to using those voices, there's no financial pressure to cap how much you listen to. You could use Shmia for one short email or for an entire audiobook-length document in a single day, and the cost to run it is the same: essentially nothing, because it's your computer doing the work, not a rented server per request. That's also why the free tier requires no credit card and has no trial period — there's no meter running that eventually needs to be paid down.
The tradeoff, stated plainly, is that Shmia's premium voices (8 ElevenLabs AI voices, genuinely human-sounding) do run through a cloud API, which is why those are capped — 3 hours a month on Premium ($19.99/month), or 10 hours a month on Ultra ($39.99/month). But even then, when premium hours run out mid-month, playback automatically continues on the free local voices rather than stopping — you're never actually blocked from listening, just switched back to the unlimited tier.
Balabolka: the other genuinely unlimited free option
Balabolka deserves a fair mention here — it's also free and unlimited, and for the same underlying reason: it runs entirely offline using your Windows machine's own resources rather than a metered API. The real tradeoffs are the voices themselves (the more robotic OS-level kind rather than natural-sounding AI voices), a dated interface, being Windows-only with no Mac version, and a paste/import workflow rather than a one-shortcut, works-in-any-app mechanic. If voice quality and cross-app convenience matter less to you than having zero limits and zero cost on Windows specifically, it's worth considering.
If you want unlimited free listening with natural-sounding local voices on both Mac and Windows, plus the option to add human-sounding premium voices later, Shmia's free tier is built for exactly that — genuinely uncapped, because it's generated on your own computer rather than metered through a cloud API.
Is Shmia really unlimited on the free tier?
Yes. Shmia's free tier gives unlimited listening using 10 built-in local voices, with no credit card, no trial period, and no word or character cap. There's no daily quota or minutes limit — you can use it for one sentence or an entire book with the same free plan.
How can Shmia afford to make listening unlimited for free?
Shmia's free-tier voices generate speech entirely on your own computer rather than calling a metered cloud API for every request. Because there's no per-minute server cost for local speech generation, there's no financial reason to cap it — the cost structure that forces other apps to meter their free tiers simply doesn't apply to on-device generation.
Which free text-to-speech tiers actually have no limit?
Among the apps compared here, Shmia and Balabolka both offer genuinely unlimited free listening. NaturalReader caps its free tier at 20 minutes per day, ElevenReader's free tier caps premium-voice listening around 10 hours per month with no unlimited fallback, and Speechify's free tier is limited rather than unlimited.
