Terms of Service

Last updated 16 September 2026

These terms govern your use of Spellflow. By using the site or creating an account, you agree to them. If you do not agree, please do not use the service.

What Spellflow is

Spellflow turns an idea into an ordered build plan where every step is a prompt you can paste into your own AI tools. The prompt tool on the homepage is free and needs no account. Workflow is a signed in workspace that generates plans and step prompts against a run allowance.

Accounts

Workflow requires an account. Accounts are created through Supabase and need a confirmed email address. You are responsible for keeping your login details secure and for activity that happens under your account.

Acceptable use

Do not use Spellflow to break the law, to infringe anyone else's rights, or to generate harmful content. We run a safety check on the text sent to the model and may refuse a request. The free prompt tool is rate limited by IP address so it stays available to everyone.

Runs and allowances

A run is one build plan or one step prompt, generated on Spellflow's key. Each plan carries a run allowance over a rolling window. The subscription allowance does not roll over. Purchased credits are spent only once your allowance is used up, and they last for one year, including if you cancel.

Payments

Payments are handled by Stripe. We do not store your card details. The price shown when you upgrade is the amount and currency Stripe charges you. Spellflow does not detect your region, so you are charged in that one currency wherever you are. You can manage or cancel a subscription from the billing portal inside your account.

Bring your own key

You can connect a key from OpenAI, Anthropic, Gemini, or NVIDIA. It is held in memory for the session, sent only to run your request, and never stored or logged. You are responsible for your own usage and costs with that provider.

Model output

Plans and prompts are generated by a third party model. Output can be wrong or incomplete, so review it before you rely on it. You are responsible for what you do with the results.

Your content

You keep ownership of what you put into Spellflow and what it generates for you. You grant us only the permission we need to run the service for you. Spellflow and its own software remain ours.

Availability and liability

The service is provided as is, without warranties, to the extent the law allows. We are not liable for indirect or consequential loss, or for loss caused by your use of generated output. Nothing in these terms limits any liability that cannot be limited by law.

Changes

We may update these terms as the product changes. If we make a significant change, we will update the date above. Continuing to use Spellflow after a change means you accept the updated terms.
