About
SayIt API is a Grok-powered text-to-speech API built by the okizzy.com team. We are a small, independent team building developer tools.
Why we built SayIt
Most text-to-speech APIs are either too expensive, too complex, or both. ElevenLabs is excellent but priced for enterprise budgets. OpenAI TTS is affordable but lacks multilingual depth and speech tag support. Existing Grok TTS integrations require you to manage your own storage, authentication, and billing infrastructure.
We wanted something that an indie developer could drop into a side project in an afternoon - with a free tier that is actually useful, documentation that is actually complete, and pricing that does not change month to month based on fundraising needs.
SayIt is the API we wished existed. Grok TTS does the hard part. We handle everything around it: storage, signed URLs, rate limiting, usage tracking, billing, and support.
What we care about
Transparent pricing
We publish our actual cost from xAI (~$0.004–$0.006 per audio minute) and price with a thin, documented margin. No VC-subsidized pricing that changes without warning.
Developer-first
Good documentation is not optional. Every parameter is explained, every error code is listed, and every code example is copy-paste ready. We use the API ourselves.
No bloat
One endpoint. One job. We will not build a voice cloning studio, a podcast editor, or a browser extension. SayIt does text-to-speech and does it well.
Reliability over features
We would rather have 99.9% uptime and fewer features than chase a feature list with unpredictable availability. Stability is a feature.
Built on
SayIt API is powered by xAI's Grok TTS model. We are not affiliated with xAI; we are an independent API layer that makes Grok TTS accessible to developers without the infrastructure overhead.
The stack: Next.js frontend, Express API server, local audio storage with 24-hour expiry. Everything is monitored and we page ourselves on errors - we do not find out about downtime from customer emails.
