§ Legal

Terms of Service

Effective date: July 10, 2026

These Terms of Service (the “Terms”) govern your access to and use of the websites and products operated by Essarion (“Essarion,” “we,” “us,” or “our”) — including essarion.com, ResearchAnything, Sourcipedia, Agents, Essarion Build, and our Platform API (together, the “Services”). By accessing or using the Services, you agree to these Terms.

Please read Section 4 carefully. It explains how our Services use artificial intelligence, and why their outputs can be incomplete, outdated, or wrong. Our Services are tools that assist you — not a substitute for professional judgment.

01 Acceptance of these Terms

By accessing or using the Services you confirm that you have read, understood, and agree to be bound by these Terms and by our Privacy Policy, which is incorporated here by reference. If you are using the Services on behalf of an organization, you represent that you have authority to bind that organization, and “you” refers to both you and that organization. If you do not agree with these Terms, do not use the Services.

Some products publish additional or product-specific terms. Where those apply, they supplement these Terms and, to the extent of a direct conflict, govern your use of that product.

02 The Services

Essarion builds AI products, including: ResearchAnything (AI research workspace), Sourcipedia (a cited, self-evolving knowledge base), Agents (a platform for autonomous agent runs), Essarion Build (a developer SDK and CLI coding agent), and our Platform API. We may add, change, remove, or discontinue features, models, and products over time, and some capabilities are experimental and may change or be withdrawn without notice.

03 Eligibility & accounts

You must be at least 16 years old (or the age of digital consent in your jurisdiction, if higher) to use the Services. Some products are invite-based or may enable, disable, or limit new registrations at any time.

Where a product offers accounts, you are responsible for keeping your credentials confidential and for all activity under your account. Provide accurate information, keep it current, and notify us promptly at hello@essarion.com if you suspect unauthorized use. We store passwords only as salted bcrypt hashes and never in plain text.

04 AI-generated content — accuracy disclaimer

Our Services rely on artificial intelligence, including large language models and automated retrieval, ranking, and summarization. AI systems can and do produce output that is inaccurate, incomplete, outdated, biased, or entirely fabricated (“hallucinated”) — including invented facts, misattributed or non-existent quotes, citations that do not support the claim they are attached to, and code that is insecure or does not work.

Reports, summaries, evaluations, scores, extracted quotes, generated code, agent actions, and chat responses are generated or assisted by AI and are provided for informational purposes only. They are not professional advice of any kind — legal, medical, financial, tax, safety, or otherwise — and must not be relied on as the sole basis for any decision.

You are responsible for independently reviewing and verifying anything important before you rely on it, share it, execute it, or deploy it. When our Services act autonomously (for example, running code, editing files, or operating a browser or connected account on your behalf), you are responsible for the scope and consequences of the actions you authorize.

05 Acceptable use

You agree not to use the Services to:

  • break any law or regulation, or infringe anyone’s rights, including intellectual-property, privacy, or publicity rights;
  • generate or distribute content that is unlawful, defamatory, harassing, hateful, or that facilitates harm;
  • produce misinformation, plagiarism, or academic dishonesty, or present AI-generated output as independently verified fact;
  • attempt to reverse-engineer, scrape, overload, disrupt, or bypass rate limits, access controls, or security of the Services;
  • use automated means to access the Services outside of interfaces we provide, or resell or redistribute the Services without our written permission;
  • upload malware, or submit content or credentials you do not have the right to submit; or
  • violate the terms, robots directives, or rate limits of any third-party source, provider, or connected account the Services access on your behalf.

We may investigate suspected violations and suspend or terminate access for conduct we reasonably believe breaks these Terms or harms the Services, other users, or third parties.

06 Your content & outputs

“Your Content” means the queries, prompts, files, documents, and other material you submit. You retain ownership of Your Content. You grant us a non-exclusive, worldwide license to host, process, transmit, and display Your Content solely to operate, secure, and improve the Services and to provide them back to you — for example, sending your input to AI models and providers and storing your work.

Subject to these Terms and the rights of third parties in any retrieved or referenced material, the outputs generated for you (“Outputs”) are yours to use. Because AI can produce similar results for different users, Outputs may not be unique, and we make no representation that Outputs are original or non-infringing. You are responsible for how you use Outputs, including any attribution required by cited sources or applicable licenses.

07 Third-party services & sources

The Services depend on third parties, including AI model providers, web-search providers, academic databases, browser-automation providers, identity and integration providers, and cloud hosting and storage. Your use of the Services and the content they retrieve is also subject to those third parties’ terms. We are not responsible for third-party services or for the content, accuracy, or availability of external sources, and links or citations to external sites are not endorsements. See the Privacy Policy for how data is shared with these providers.

08 Plans, fees & billing

Some products offer free and paid plans that differ in features and usage limits, and some usage is metered. Prices and limits shown in a product may change; we will make reasonable efforts to communicate material changes. Where paid subscriptions are offered, fees are billed in advance and, except where required by law, are non-refundable. You are responsible for any taxes. If a payment fails or a subscription lapses, we may suspend paid features or downgrade your account.

09 Intellectual property

The Services themselves — including their software, design, branding, and the “Essarion,” “ResearchAnything,” “Sourcipedia,” “Agents,” and related names and logos — are owned by us or our licensors and protected by intellectual-property laws. Except for components we make available under an open-source license (Section 10), these Terms grant you a limited, non-exclusive, non-transferable, revocable license to use the Services for their intended purpose. No rights are granted except as expressly stated here.

10 Open-source components

Certain Essarion products — including the Essarion Build SDK and CLI — are distributed as open-source software under their own licenses (for example, the Apache License 2.0). Your use of those components is governed by the applicable open-source license accompanying them, which controls over these Terms to the extent of any conflict for that component. Open-source components are provided “as is” without warranty, as stated in their licenses.

11 Suspension & termination

You may stop using the Services and delete your account at any time. We may suspend or terminate your access, with or without notice, if you breach these Terms, if required by law, or if necessary to protect the Services or others. On termination, your right to use the Services ends; sections that by their nature should survive (including disclaimers, limitations of liability, and indemnification) will survive. We handle data after account closure as described in the Privacy Policy.

12 Disclaimer of warranties

To the fullest extent permitted by law, the Services and all Outputs are provided “as is” and “as available,” without warranties of any kind, whether express, implied, or statutory, including implied warranties of merchantability, fitness for a particular purpose, non-infringement, and any warranty regarding accuracy, reliability, completeness, or availability. We do not warrant that the Services will be uninterrupted or error-free, that defects will be corrected, or that any Output is accurate, current, or fit for your purpose.

13 Limitation of liability

To the fullest extent permitted by law, we and our affiliates and suppliers will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, data, goodwill, or other intangible losses, arising out of or relating to your use of (or inability to use) the Services or any reliance on Outputs, even if we have been advised of the possibility of such damages.

To the fullest extent permitted by law, our total aggregate liability arising out of or relating to the Services or these Terms will not exceed the greater of the amounts you paid us for the Service giving rise to the claim in the twelve months before the event, or USD 100. Some jurisdictions do not allow certain limitations, so some of these limitations may not apply to you.

14 Indemnification

You agree to indemnify and hold harmless Essarion and our officers, employees, and agents from any claims, damages, liabilities, and expenses (including reasonable legal fees) arising out of your use of the Services, Your Content, your Outputs, or your breach of these Terms or of any law or third-party right.

15 Governing law & general terms

These Terms are governed by the laws applicable at our principal place of business, without regard to conflict-of-laws rules, and you agree to the exclusive jurisdiction of the courts located there, except where mandatory local law provides otherwise. If any provision is held unenforceable, the rest remains in effect. Our failure to enforce a provision is not a waiver. These Terms, together with the Privacy Policy and any product-specific terms, are the entire agreement between you and us regarding the Services. You may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition, or sale of assets.
