I'm Aishwarya, the product marketing manager for Async.ai. Today, I'd like to introduce Async API, our premium voice AI technology designed especially for developers.
What is Async AI?
Async is the advanced AI technology that has been silently powering Podcastle’s magic for years and is now stepping into the spotlight and becoming available to developers worldwide.
At Podcastle, we've spent years at the forefront of AI text-to-speech innovation, but we kept encountering the same frustration — existing solutions were either too complex, too expensive, or too limiting for the creative minds building tomorrow's applications.
That's why we built Async API with a developer-first philosophy from day one. Every decision, from our 3-second voice cloning to our straightforward pricing model, was made by asking: "What would make a developer's life easier?"
Async AI offers:
User-friendly API
Realistic, expressive voices that reflect human intonation and emotional nuances with remarkable accuracy.
Voice cloning in just 3 seconds.
Supports over 20 languages (coming soon!) and countless voice styles.
Developer-friendly prices.
Powered by our latest asyncFlow v1.0 model, we deliver premium voice quality at competitive prices. With advanced emotional inflexion, rhythm control, low latency responses, and reliable uptime, our technology seamlessly integrates from prototype to production-ready solutions.
Whether you're building interactive experiences, accessibility tools, or content at scale, our AI voices truly connect with your audience.
Check us out at async.ai today! To celebrate this launch, we are offering credits for $10 if you sign up today!
Thanks for all the love you've shown for Podcastle and Async
