Frequently asked questions

Can I test the API for free?

While we do not directly have a free trial for our API, you can test out the functionality of our humanizer by signing up for a free account. This will give you 350 word credits to test out the functionality. If you need more credits, you can purchase them on the pricing page.

What AI models do you use for paraphrasing?

Phrasly.AI is the first platform to be fully powered by custom AI models on our own hardware. We do not use the OpenAI GPT-3 model, or any other publicly available models and resell them at a markup compared to competitors. Our models are fully custom and trained on our own hardware, which allows us to be flexible with our pricing and offer the best value to our customers.

Are there any usage limits?

We have no request limits, however, your quota is based on the number of words you have purchased. If you need more words, you can purchase them on the pricing page.

How do I use the API?

We conform to the REST standard, which means all endpoints can be access through web requests. Check our documentation for more information specific to your use case.

Do you support webhooks or callbacks?

Webhook integration and web callbacks are available to customers upon request. If you're looking to process high volumes of content and require webhook integration, reach out to us at [email protected].
