Premise

Terms of Service

Last updated: 10 June 2026 · Effective: 10 June 2026

1. Who we are; agreement to these terms

Premise is an AI-assisted book-writing service available at premise.systems (the “Service”), operated by Foglight Story Systems LLC, doing business as Premise (“Premise,” “we,” “us”).

By creating an account or using the Service, you agree to these Terms of Service and to our Privacy Policy, which explains how we handle your information. If you do not agree, do not use the Service.

2. The service

Premise helps you develop a book from an initial idea to a complete draft. You provide creative input — a premise, descriptions, choices, and instructions — and the Service generates story material in stages (such as a premise, ending design, world, cast, threads, plot, chapter map, scenes, and draft chapters), using third-party artificial-intelligence models. The Service also includes a workshop chat for discussing your project.

Generation runs as background jobs that can take from seconds to many minutes per stage. We are continually improving the Service, and features may change, be added, or be removed.

3. Eligibility

You must be at least 18 years old to use the Service. By using the Service you represent that you are 18 or older and able to form a binding contract.

4. Your account

You sign in through our authentication provider (Clerk), using email and password or Google sign-in. You agree to provide accurate information, to keep your credentials secure, and to notify us promptly of any unauthorized use of your account. You are responsible for activity under your account. Each account is for one person; do not share accounts or resell access.

5. Plans, billing, and cancellation

The Service offers a free tier, which includes the early stages of a project, and paid subscription plans, which unlock the full generation pipeline and include a monthly book allowance. Current plans, prices, and what each includes are listed on our pricing page; the pricing page is part of these terms. Paid plans are currently offered to customers in the United States only.

Book allowance

Paid plans include a set number of full books per billing period; the number depends on your plan and is listed on our pricing page. Starting a new project and generating its early stages does not use your allowance; advancing a project past the character stage into the full pipeline uses one book for that billing period. A book you have already advanced stays available to you and is not charged again in later billing periods. Your allowance resets at the start of each billing period, and unused books do not carry over.

Recurring billing

Paid plans are subscriptions that renew automatically (monthly, unless stated otherwise) and your payment method is charged at the start of each billing period until you cancel. Before you subscribe, the recurring charge, the renewal date, and the date by which you must cancel to avoid the next charge will be disclosed at checkout and shown in your account settings. Payments are processed by Stripe through our billing provider; we never receive or store your full card details. Where we are required to collect sales tax, it is included in the price shown.

Cancellation

You can cancel your subscription at any time from your account settings, as easily as you signed up. Cancellation takes effect at the end of the current billing period: you keep paid access until then, and you are not charged again. Canceling does not delete your account or your books, and any book you have already advanced remains available to you.

Refunds

Refunds are tied to your book allowance. If you have not yet used any of the current billing period’s book allowance — that is, you have not advanced any project past the character stage into the full pipeline during the current period — you may request a refund of that period’s most recent charge by contacting us, and we will refund it. Once you have used a book in the current billing period, that period’s payment is non-refundable, because generating a full book incurs real compute cost the moment it runs. If we issue a refund, your paid access ends immediately and any unused book allowance for that period is forfeited. Except as described here or where required by law, payments are non-refundable, and deleting your account does not entitle you to a refund of amounts already paid.

Plan changes

If you upgrade to a higher plan, the change takes effect immediately and unused time on your old plan is credited pro-rata toward the new one; if you downgrade, you keep your current plan until your renewal date, and the lower plan begins then.

Price changes

We may change plan prices or what plans include. Price changes take effect at your next renewal, and we will give you reasonable advance notice (at least the email associated with your account) so you can cancel first if you wish.

6. Your content and who owns what

Your input

You retain all rights you have in the material you submit to the Service — your ideas, premises, descriptions, instructions, and chat messages (“Input”).

Generated output

As between you and Premise, you own the story material the Service generates for your projects (“Output”), and we assign to you whatever right, title, and interest we may have in it. You may use your Output for any purpose, including commercial publication, subject to these terms and applicable law.

Our license to operate

You grant us a limited, non-exclusive, worldwide license to host, store, process, reproduce, and transmit your Input and Output solely to operate, secure, and improve the Service — for example, storing your projects, sending your content to our AI providers to generate the next stage, and keeping operational logs. This license ends when your content is deleted from the Service (see the Privacy Policy for deletion and retention details). We do not use your Input or Output to train AI models, and we do not claim ownership of your books.

Your responsibilities for content

You are responsible for your Input and for how you use and publish your Output. You represent that your Input does not infringe anyone else’s rights and that your use of the Service complies with the Acceptable Use section below.

7. AI-generated content: important realities

Output is produced by third-party AI models (currently provided by OpenAI and Anthropic, with embeddings by Voyage AI). You should understand, and you accept, the following:

• Accuracy and quality are not guaranteed. AI output can be wrong, inconsistent, incomplete, or unsuitable, and may require substantial human revision.
• Uniqueness is not guaranteed. AI models can produce similar output for different users. We do not warrant that your Output is original or non-infringing.
• Copyright in AI-generated material is legally unsettled. In the United States, works generated by AI without sufficient human authorship may not qualify for copyright protection. We make no warranty that your Output is copyrightable or registrable; your own creative contribution and revision matter.
• Provider policies pass through. Your use of the Service must also comply with the usage policies of our AI providers (OpenAI and Anthropic). We may refuse or stop generation that violates them.
• Output may include mature themes. Fiction generation can produce dark or mature story content within the bounds of our Acceptable Use policy.

8. Acceptable use

Do not use the Service to create, request, store, or distribute material that is illegal, or to do any of the following. We may remove content, refuse generation, suspend, or terminate accounts that violate this section, and we cooperate with law enforcement where legally required.

• Absolutely prohibited: any sexual content involving minors, real or fictional; content that sexualizes, grooms, or endangers children in any way.
• Content that is unlawful where you or we operate, including credible threats, incitement to violence, or instructions for serious wrongdoing presented for real-world use.
• Harassment, defamation, or content targeting real, identifiable private individuals.
• Infringing material — submitting others’ copyrighted text as your Input without permission, or attempting to generate derivative works of material you do not have rights to.
• Attempting to probe, breach, or test the Service’s security or another user’s data isolation; accessing data that is not yours; reverse-engineering non-public parts of the Service.
• Abusing the Service’s resources: circumventing rate limits or plan entitlements, automated scraping, or using the Service to build or power a competing generation service.
• Misrepresenting AI-generated output as the work of a specific real person, or using the Service for deception, fraud, or spam.

We report apparent child sexual abuse material to the National Center for Missing & Exploited Children (NCMEC) through its CyberTipline as required by U.S. law (18 U.S.C. § 2258A), preserve related records, and cooperate with law enforcement.

To report content that violates this section, or other abuse, email support@premise.systems; we review and act on reports. (Copyright complaints follow the separate DMCA process below.)

9. Our intellectual property

The Service itself — the software, pipeline design, site, and the Premise name and branding — belongs to us and our licensors. These terms do not grant you any rights in it except the right to use the Service as intended. Feedback you choose to send us may be used without obligation to you.

10. Copyright complaints (DMCA)

If you believe content on the Service infringes your copyright, send a notice meeting the requirements of 17 U.S.C. § 512(c)(3) to our designated agent at support@premise.systems. We respond to valid notices, may remove identified material, and may terminate repeat infringers’ accounts.

11. Termination

By you: you may stop using the Service and delete your account at any time. Account deletion follows the schedule described in the Privacy Policy (a grace period, then permanent deletion of your data). Deleting your account does not entitle you to a refund of amounts already paid.

By us: we may suspend or terminate your access if you materially violate these terms (including Acceptable Use), if required by law, or if we discontinue the Service. Where reasonable, we will give you notice and an opportunity to export your work.

Sections that by their nature should survive termination (including ownership, disclaimers, limitation of liability, and governing law) survive.

12. Disclaimers

THE SERVICE AND ALL OUTPUT ARE PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, OR UNINTERRUPTED OPERATION. GENERATION TIMES VARY AND JOBS MAY OCCASIONALLY FAIL; WE DO NOT WARRANT THAT ANY PARTICULAR GENERATION WILL SUCCEED OR THAT CONTENT WILL NOT BE LOST — KEEP YOUR OWN COPIES OF MATERIAL THAT MATTERS TO YOU. NOTHING IN THE SERVICE IS PROFESSIONAL (LEGAL, PUBLISHING, OR OTHER) ADVICE.

13. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW: (a) WE ARE NOT LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUES, DATA, OR GOODWILL; AND (b) OUR TOTAL LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE IS LIMITED TO THE GREATER OF $100 OR THE AMOUNTS YOU PAID US IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM. SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS, SO PARTS OF THIS SECTION MAY NOT APPLY TO YOU. Nothing in these terms limits or waives any right you have under the Massachusetts Consumer Protection Act (M.G.L. c. 93A) or any other right that cannot be waived by law.

14. Indemnification

You will defend and hold us harmless from claims and costs (including reasonable attorneys’ fees) arising from your Input, your publication or commercial use of Output, or your violation of these terms or of law.

15. Governing law and disputes

These terms are governed by the laws of the Commonwealth of Massachusetts, without regard to conflict-of-law rules. Disputes will be resolved in the state or federal courts located in that state, and both parties consent to their jurisdiction. To the extent permitted by law, each party waives any right to a jury trial and agrees claims may be brought only individually, not as part of a class action.

16. Changes to these terms

We may update these terms as the Service evolves. For material changes we will give notice (for example, by email or an in-product notice) before the changes take effect. Continuing to use the Service after the effective date means you accept the updated terms; if you do not, stop using the Service and cancel any subscription.
