Terms and Conditions
Last updated: May 11, 2026
These Terms apply to SESLIO websites, demos, text-to-audio tools, AI audiobook workflows, remixing, video generation, storage, downloads, and related services.
1. Acceptance
By using SESLIO, you agree to these Terms. If you use SESLIO for a company, publisher, agency, client, or other organization, you confirm that you have authority to accept these Terms for that organization.
If you do not agree, do not use the service.
2. What SESLIO Does
SESLIO is a technology provider. The service takes text, documents, URLs, book content, settings, and other materials provided by users and uses AI systems to create audio or related media outputs.
We do not act as a publisher, rights clearance service, legal reviewer, editor, or copyright advisor. Our AI system converts provided text and settings to audio; that is the technical service.
3. Your Content and Responsibility
You are fully responsible for anything you submit to SESLIO and anything you create, download, publish, share, sell, or otherwise use from SESLIO.
You must make sure that you have all rights, licenses, permissions, consents, and legal bases needed to upload content, convert it to audio, generate related media, and use the generated files. This includes copyright, trademark, privacy, publicity, contract, confidentiality, and platform-policy rights.
Do not upload or generate content that is illegal, infringing, deceptive, defamatory, harassing, harmful, or otherwise violates another person's rights.
4. Copyright and Rights Issues
SESLIO cannot know whether the text, book, article, URL, document, prompt, instruction, voice choice, or generated audio has copyright or other rights issues. You are responsible for checking that before using the service and before publishing or monetizing any output.
Generated audio files are used at your own risk. If a rights holder, platform, publisher, author, narrator, artist, agency, or other third party makes a claim related to your content or generated audio, you are responsible for that claim.
SESLIO may remove, disable, reject, or stop processing content if we believe it may violate law, these Terms, platform policies, or another person's rights.
5. AI Output Quality and Unpredictability
AI systems are probabilistic and can behave in unexpected ways. SESLIO does its best to generate useful audio, but we do not guarantee that audio quality, pronunciation, pacing, language, translation, voice consistency, emotion, tone, editing, metadata, file format, or overall result will meet your expectations.
Outputs may contain errors, omissions, additions, artifacts, mistranslations, mispronunciations, noise, unusual phrasing, unstable voices, incomplete sections, or other unexpected results. You must review generated audio before using it publicly or commercially.
SESLIO provides generated outputs as-is. A result being unexpected, low quality, unsuitable, rejected by a platform, or different from what you expected does not create a guarantee, warranty, refund obligation, or liability unless required by law or agreed in writing.
6. Generated Audio and Similar Outputs
Subject to these Terms and any third-party rights, you may use generated audio files that you lawfully create through SESLIO. SESLIO does not guarantee that any output is unique, copyright-free, non-infringing, commercially usable, or accepted by Spotify, YouTube, Storytel, app stores, publishers, distributors, or any other platform.
You are responsible for labels, disclosures, approvals, metadata, distribution rules, monetization rules, and any AI-content or synthetic-media requirements that apply where you use the output.
7. Accounts, Credits, and Availability
You are responsible for your account, credentials, usage, uploaded files, generated files, and backups. SESLIO may change, pause, limit, suspend, or discontinue features at any time.
Processing may fail, take longer than expected, or become unavailable. Unless required by law or agreed in writing, fees or credits used for processing are not refundable simply because an output does not meet your expectations.
8. Files, Storage, and Deletion
SESLIO may process and store submitted content, generated audio, logs, and related technical data to provide the service, operate accounts, prevent abuse, troubleshoot issues, and improve reliability. You should keep your own copies of important files.
We may delete or restrict access to files, jobs, accounts, or data when needed for security, operations, legal compliance, abuse prevention, unpaid balances, or service maintenance.
9. Prohibited Use
You may not use SESLIO to break the law, infringe rights, impersonate people without permission, create deceptive synthetic media, mislead listeners, distribute spam, harass others, bypass security, overload the service, reverse engineer the service, or interfere with other users.
You may not use SESLIO in a way that violates the rules of third-party platforms, voice providers, payment providers, cloud providers, or distribution channels connected to your workflow.
10. No Warranties
To the maximum extent permitted by law, SESLIO is provided as-is and as-available, without warranties of any kind. We disclaim implied warranties of merchantability, fitness for a particular purpose, title, non-infringement, uninterrupted availability, accuracy, and error-free operation.
Nothing in these Terms excludes warranties or rights that cannot be excluded under applicable law.
11. Liability Limits
To the maximum extent permitted by law, SESLIO will not be liable for indirect, incidental, special, consequential, exemplary, punitive, or lost-profit damages, or for loss of data, reputation, business, revenue, goodwill, content, generated audio, platform access, or publishing opportunities.
To the maximum extent permitted by law, SESLIO's total liability for any claim related to the service is limited to the greater of the amount you paid SESLIO for the service in the three months before the claim or USD 100.
12. Indemnity
You agree to defend, indemnify, and hold harmless SESLIO from claims, damages, losses, liabilities, costs, and expenses arising from your submitted content, generated audio, use of outputs, publication or monetization, breach of these Terms, or violation of law or third-party rights.
13. Changes and Termination
We may update these Terms from time to time. Continued use of SESLIO after changes means you accept the updated Terms.
We may suspend or terminate access if we believe you violated these Terms, created risk for SESLIO or others, failed to pay amounts owed, or used the service in a harmful or unlawful way.
14. Contact
