Terms of service

These Terms govern your use of Ottopen (“Ottopen,” “we,” “us”). By creating an account or using the Service, you agree to them. If you do not agree, do not use Ottopen.

Accounts

You are responsible for maintaining the confidentiality of your account credentials and for activity under your account. Contact security@ottopen.app if you suspect unauthorized access.

Your content and ownership

You retain ownership of your manuscripts, uploaded materials, notes, generated drafts, and audiobook outputs, subject to the rights and terms of any third-party AI, voice, or storage provider involved in producing or hosting that content.

You grant Ottopen a limited, revocable license to host, process, transmit, display, and back up your content solely as needed to operate the Service for you.

Your rights and responsibilities

You are responsible for making sure you have the rights to any content you use in Ottopen, including:

• manuscripts, outlines, and story notes;
• characters, names, and reference materials;
• uploaded audio assets and voice prompts; and
• any material used for commercial publishing or audiobook distribution.

Voice, likeness, and performance rights

You may not upload, clone, imitate, or generate a real person's voice, name, likeness, or performance style unless you have all rights, permissions, and legally required consent to do so.

AI providers and output review

Ottopen may use third-party AI and voice providers, including Anthropic, OpenAI, and ElevenLabs when those integrations are enabled. Your use of those features may also be subject to the providers' own terms and acceptable-use rules.

AI output can be incomplete, inaccurate, or unexpectedly similar to other works. You are responsible for reviewing, editing, and validating all generated output before publishing, distributing, or relying on it. Format conversion outputs, including screenplay, treatment, pitch, query, and narration-plan drafts, are structured creative drafts and are not guaranteed final professional scripts, treatments, or production documents.

Acceptable use

You may not use Ottopen to:

• infringe copyright, privacy, publicity, trademark, or other rights;
• generate or distribute unlawful abuse material, non-consensual sexual content, or targeted harassment;
• scrape, resell, reverse engineer, or interfere with the Service; or
• bypass security controls, abuse-prevention safeguards, or account boundaries.

Plans and pricing

Ottopen's current public plans are Draft, Studio, Audiobook Studio, and Publisher. Draft is free. Studio is $20/month and includes hosted AI writing support, expanded voice previews, and playback-only test renders. Audiobook Studio is $100/month and includes the voice casting workflow, the chapter audio render queue, expiring playback and download links, and 25,000 finished audio characters each month. Studio and Audiobook Studio may use cheap, standard, and premium AI credit buckets; optional AI top-up packs and audio prepaid packs may be available in-app when configured. Publisher plans are custom.

Creating an account alone does not authorize Ottopen to charge you. Paid subscriptions are purchased through the applicable checkout flow. Cancellation, renewal timing, and any metered usage details are disclosed in checkout, account billing settings, or a written custom agreement.

Audiobook rendering and usage fees

The free Draft plan does not generate audio. Studio preview and test audio is playback-only and is not offered as a production download; preview and test audio may expire. Final downloadable chapter audio requires Audiobook Studio or approved production access. Audiobook Studio includes 25,000 finished audio characters each month. Additional final audiobook rendering is metered: Ottopen displays the estimated cost in the application before each final render, and you must confirm before usage is charged. Additional usage is sold as prepaid character credit packs purchased in-app. Failed renders are not billed as successful finished audio, and you may retry without incurring a charge. You are responsible for the rights to all content you submit for audio generation, and generated audio is subject to provider limitations and availability.

Cancellations and refunds

You can cancel paid subscriptions through account billing settings at any time. Cancellation usually stops future renewals but does not automatically refund past charges. Already-purchased prepaid audio credit packs do not refund automatically. Refund requests are reviewed case by case unless a separate written agreement says otherwise.

Service changes and limited features

Ottopen is an evolving service. Individual subfeatures may be added, changed, removed, delayed, or labeled limited or coming soon. When a subfeature is labeled limited inside the product, its behavior may change.

Termination and deletion

You may stop using Ottopen at any time. We may suspend or terminate access if you violate these Terms, create material legal risk, or threaten the security of the Service. Account deletion and retention are handled as described in the Privacy Policy.

No legal or publishing guarantee

Ottopen does not guarantee copyright registration, publishing approval, audiobook platform acceptance, legal compliance for your content, or commercial success.

Disclaimers and liability limits

To the maximum extent allowed by law, Ottopen is provided “as is” and “as available.” We disclaim implied warranties, including merchantability, fitness for a particular purpose, and non-infringement. We are not liable for indirect, incidental, special, consequential, or punitive damages.

To the maximum extent allowed by law, Ottopen's total liability for claims arising out of or relating to the Service will not exceed the greater of one hundred U.S. dollars (US$100) or the amount you paid to Ottopen in the twelve months before the event giving rise to the claim.

Governing law and venue

These Terms are governed by the laws of the State of Illinois, without regard to conflict-of-law rules. Any dispute arising from or relating to these Terms or the Service will be brought in the state or federal courts located in Cook County, Illinois, unless applicable law requires otherwise.
