Frequently asked questions

Everything you need to know about subscriptions and billing.

Bring-your-own-key is a term that represents the operating model where the user brings their own API keys. By doing this, we avoid the overhead of centrally managing AI token usage which keeps our operating costs low, meanwhile you benefit from unlimited access, dedicated limits and extremely cost-effective usage.

In practice, you pay us for using our software and you pay OpenAI for any AI usage you incur. It works out very cost-effective when compared to plans where the AI usage is included in the plan price.

This means that you will need to have a paid OpenAI API account with billing enabled. Settings up an OpenAI account and getting hold of an API key is super simple, and we will guide your through the entire process.

You should also ensure that your rate limits are sufficient to use Machined, we require a minimum of 200 RPM and 50,000 TPM limits for the gpt-3.5-turbo and gpt-3.5-turbo-16k models. You can check your rate limits for your account at

The cost of an article depends on the model used and the length of the article so it isn’t possible to provide or predict an exact cost before an article is generated.

Looking at the thousands of article written by our users, the average cost for an article is:
– Roughly $0.08 when using GPT-3.5 and
– Roughly $0.80 when using GPT-4

Remember this is the cost your pay directly to OpenAI.

No, we do not offer a lifetime deal.

For what it’s worth, we used to have a special LTD for very early adopters when we were first starting up but that was a while ago and we have since transitioned to a subscription-only model.

No, we can do better than that! We offer a Free Plan that let’s you create three full clusters with up to 18 articles, every single month.

The free plan includes our fully unrestricted AI Content Writer with choice of AI model, and multiple writing styles. This gives you a much better chance to see our content in as much detail as you want before committing to a paid plan. You can rewrite articles as many times as you like to see how all the features work. Hell, you can even publish them all and see how well our clusters rank 🙂

Please note that some other features are restricted in the free plan; you won’t be able to create manual clusters or publish directly to your website – you will need to upgrade for those.

Don’t forget, even though our plan is free, you need to cover your own token usage costs.

You can cancel your subscription at any time and you will no longer be charged. After canceling, you will have full access to your account and be able to generate content until the end of your billing cycle.

Yes, we offer a 14-day money back guarantee.

If you aren’t satisfied in the first 14 days of trying the service, reach out to our team at and we can provide a refund.

You can contact our team via email at  or in-app chat.

We strive to respond to all enquiries as soon as we can but please allow at least one working day for our team to get back to you.
