Frequently asked questions

How does credit pricing compare to subscriptions?
With subscriptions, you pay a fixed monthly fee whether you use the service or not. With Hudsonly AI, you buy credits upfront and spend them only when you make API calls. If you have a quiet month, you pay nothing. Credits never expire, so there's no "use it or lose it" pressure.
What technology powers your services?
Our text-to-speech engine supports 54 voices across 8 languages. For avatar videos, we offer both audio-driven and video-driven animation modes. All services run on dedicated GPUs with auto-scaling infrastructure for consistent performance.
Can I switch from ElevenLabs or D-ID?
Yes. Our REST API follows standard conventions — send a POST request with your inputs and get back a URL to your generated content. Most developers can integrate in under an hour. We offer 50 free credits to test before committing.
Do credits expire?
No. Credits never expire. Once purchased, they remain in your account until you use them. No monthly minimums, no "use it or lose it" policies.
How does quality compare?
Our TTS engine produces natural, expressive speech comparable to leading commercial providers. Our avatar models generate smooth, realistic facial animations. We recommend trying the free credits to evaluate quality for your use case.
What about uptime and reliability?
Our services run on auto-scaling GPU infrastructure. Each request gets a dedicated GPU — there's no shared resource contention. The platform scales automatically to handle demand spikes.
