Airy is a free AI voice tool; Kompozy is a content engine that turns a script into video and publishes it. Honest differences, pricing, and when each wins.
If you searched "Airy alternative," start with an honest distinction, because Airy and Kompozy are different kinds of tool and for most people this is not a straight swap. Airy (airy.so) is a free, fast AI voice tool — you give it text and it gives you back a spoken audio track. Kompozy is a content engine — it turns a source (a script, a video, a podcast, a Persona Brief) into finished posts, video, carousels, blogs, and newsletters, and publishes them across platforms. One makes an audio file. The other makes and distributes a week of on-brand content.
I run Kompozy, and I won't pretend it replaces a dedicated voice generator for what that job is. If all you want is a quick, free voice track to download and drop into your own editor, a focused text-to-speech tool is the right category, and a free one like Airy is a reasonable place to start. Kompozy is not a standalone TTS app that hands you a bare MP3 to use elsewhere.
So the honest split: if you need raw voice files, use a voice tool — Airy, or a more established option like ElevenLabs, Speechify, or Fish Audio. If the voice track was only ever a step toward finished, published content — captioned short-form video, posts across channels — then an "alternative voice tool" isn't quite the answer, and the production-and-publishing layer is. One useful wrinkle: Kompozy already includes native voice (HeyGen TTS) inside its avatar-video pipeline, so plenty of creators never need a separate voice app at all.
Everything below reflects Airy's public positioning as of 2026-08-09 — a free, fast voice tool with limited published detail on specs, limits, and any paid tiers — and Kompozy's product and pricing the same day. No straw men: the two tools win at different jobs.
Airy is a free, browser-based AI voice tool. You paste a script and it generates spoken audio — voiceovers, narration, and short spoken clips — quickly and without editing software or a recording setup. Its appeal is speed, a zero-friction free workflow, and being one more no-cost option in the crowded AI text-to-speech space. Beyond that, Airy publishes limited public detail about its exact voice roster, supported languages, output formats, and usage limits, so the responsible thing is to verify current capabilities on airy.so rather than quote unconfirmed numbers. What Airy does not do is produce or distribute a content operation. It makes an audio file. It does not turn that voice into a captioned short-form video, generate a talking-head or avatar clip, cut long footage into shorts, write copy in a governed brand voice across formats, build brand-exact carousels, or turn one source into a week of multi-format posts plus a blog and a newsletter — and it publishes nothing to social platforms, a blog, or email. It generates voice; producing and distributing finished content is a different job.
Most people who look past a free voice tool do so for one honest reason: an audio track isn't content. A voice file sits on your drive and reaches no one until it becomes something watchable and published — a captioned vertical video, a post, an episode. Generating the voice is the easy, increasingly commoditized part; turning it into finished assets and getting them in front of an audience every week is the actual bottleneck, and a voice generator was never built to solve it. That is the gap Kompozy fills, and it is why the two show up in the same search. Kompozy is a full AI content generation and multi-platform publishing engine: one source — a script, a video, a podcast, an RSS feed, a Persona Brief — becomes a week of on-brand assets across five buckets (video, image, text, blog, newsletter), then gets scheduled and published across the eight primary social platforms plus blog and email, held to one voice by a Persona Brief and one look by HyperFrames templates. Where Airy hands you an MP3, Kompozy wraps that same script into captioned video and posts and ships it. None of this is a knock on Airy — for a fast, free voice track it does exactly what it says. It simply stops at the audio. If your bottleneck is producing and distributing content rather than generating a voice clip, an "alternative" isn't quite what you need; the other half of the stack is — and Kompozy's built-in voice may mean you don't need a separate voice tool in the first place.
| Feature | Airy | Kompozy | Note |
|---|---|---|---|

| Captioned short-form video from a script | No | Yes | Kompozy turns a script into a captioned Persona Short or Listicle Video; Airy stops at audio. |
| AI avatar / talking-head video | No | Yes | Persona Shorts and Persona HeyGen — Kompozy only. A voice tool makes no video. |
| Clip long video into shorts | No | Yes | Clipped Shorts — Kompozy only. Airy does not touch video. |

Here's the honest pitch, and it isn't "switch from Airy to Kompozy" — because they don't do the same job. Airy generates a voice track; Kompozy generates and publishes content. The useful question a free voice tool surfaces is whether the audio was ever the point, or just a step toward getting your ideas in front of people. If it was the latter, the audio file was a detour. Kompozy takes the same script and produces the captioned video, quote graphics, carousel, blog, and newsletter that actually reach an audience where they scroll — with the voice generated inside the same pipeline.
For most creators and small teams in 2026, the bottleneck was never generating a voice clip; free tools made that trivial. It's the treadmill: nobody can hand-assemble on-brand video, posts, carousels, blogs, and newsletters for every channel every week. Kompozy turns one source into a week of that content, enforces your look with HyperFrames and your voice with a Persona Brief, and publishes across eight social platforms plus blog and email behind a per-post review gate so nothing ships unseen.
So if you genuinely just need a free audio file, use a voice tool — that's the honest advice, and Kompozy won't pretend to be a standalone TTS app. But if your real aim is turning a script into published content at volume, that's the layer a voice generator was never built to be. Start with Kompozy Starter at $99/mo (5,500 credits), or bring your own API keys to run leaner.
Airy (airy.so) is positioned as a free, fast AI voice tool. It publishes limited detail about usage limits or any paid tiers, so check airy.so directly for the current terms before you build a workflow around it.
Not a direct one. Airy generates a standalone voice track; Kompozy generates and publishes content — captioned video, posts, carousels, blogs, and newsletters across platforms. It is not a bare text-to-speech app, but it does include native voice, so many creators use it instead of pairing a separate voice tool with an editor.
It depends on the job. For standalone voice files, established options include ElevenLabs, Speechify, and Fish Audio. If your goal is turning a script into finished, published content rather than an audio file, Kompozy is the content generation and publishing engine for that — it just also happens to generate voice inside its video pipeline.
Yes. Kompozy uses native HeyGen text-to-speech inside its avatar-video formats (Persona Shorts and Persona HeyGen), so you can generate the voice and the finished captioned video in one place instead of exporting audio from a separate tool.
Feed the script (or the audio) into Kompozy and generate a Persona Short or Listicle Video — you get a captioned vertical clip, plus quote graphics, a carousel, and a blog from the same source, scheduled across the eight social platforms plus blog and email.
