# Disclaimer **Last updated: 2026-04-21** This document is a plain-language expansion of the MIT License that ships with deepdive. In case of conflict, the MIT [LICENSE](LICENSE) controls. By downloading, installing, running, linking against, or otherwise using deepdive (the "Software"), you acknowledge and agree to everything below. If you do not agree, do not use the Software. --- ## 1. Provided "AS IS" The Software is provided **"AS IS" and "AS AVAILABLE"**, without warranty of any kind, express, implied, or statutory, including but not limited to: - warranties of merchantability, fitness for a particular purpose, title, or non-infringement - warranties that the Software will be error-free, uninterrupted, secure, or free of harmful components - warranties that any defect or bug will be corrected - warranties regarding the accuracy, reliability, completeness, timeliness, or usefulness of any output produced by or through the Software, including research reports and cited content Research output from the Software is machine-generated and may contain factual errors, omissions, outdated information, misattributed citations, or hallucinated content. **Do not rely on deepdive output for medical, legal, financial, safety-critical, or other high-stakes decisions without independent verification.** --- ## 2. Limitation of liability To the maximum extent permitted by applicable law, in no event shall the authors, maintainers, contributors, copyright holders, or any person associated with the project be liable for any: - direct, indirect, incidental, special, exemplary, consequential, punitive, or any other damages - loss of profits, revenue, data, goodwill, use, opportunity, or business - service interruption, computer failure or malfunction, subscription loss, suspension, or termination - costs of procurement of substitute goods or services - claims by third parties arising out of content produced by or through the Software arising out of or in connection with the Software, its use, its inability to be used, its interaction with any third-party service, or any content produced by it, whether based on warranty, contract, tort (including negligence), strict liability, statute, or any other legal theory, and whether or not the project has been advised of the possibility of such damages. Where liability cannot be fully excluded under applicable law, it is limited to the maximum extent permitted. --- ## 3. No affiliation deepdive is an **independent, unofficial, third-party project**. It is: - **not affiliated with, endorsed by, sponsored by, or in any way officially connected to** Anthropic PBC, OpenAI OpenCorp, Google LLC, DuckDuckGo, SearXNG, Brave Software, Tavily AI, Perplexity AI, Microsoft, the Playwright project, or any other company, product, or service mentioned in the documentation, source code, or default configuration - **not an official client, SDK, integration, or partner** of any of the above - **not authorized to speak on behalf of** any of the above All product names, logos, brands, trademarks, and registered trademarks referenced anywhere in this project are property of their respective owners. Use of those names is for identification and interoperability purposes only and does not imply endorsement. --- ## 4. User responsibility You are solely responsible for: - **Your use of any third-party service reached through deepdive**, including search engines, LLM providers, and the arbitrary web pages deepdive fetches on your behalf. Your use of each service is governed by that service's own terms of service, acceptable-use policy, `robots.txt`, rate limits, and any other agreement you have with that service. Review them. Follow them. - **Web scraping and fetching.** deepdive drives a headless browser against URLs the LLM selected from search results. You are responsible for ensuring your use complies with the terms of service of the sites you cause deepdive to visit, as well as applicable laws such as the Computer Fraud and Abuse Act (US), the Computer Misuse Act (UK), GDPR, and any other relevant regime. Do not use deepdive to access sites that prohibit automated access, to bypass paywalls or authentication, or to scrape at a volume that would constitute abuse. - **Your subscriptions, API keys, and accounts.** You are responsible for all activity conducted under them and for keeping them secure. - **Compliance with all laws applicable to you and your use**, including but not limited to export control, sanctions, privacy, data protection, consumer protection, copyright, and industry-specific regulations (HIPAA, PCI-DSS, FedRAMP, GDPR, CCPA, etc.). - **The content you send through the Software and the content you receive back.** The project does not moderate, filter, store, or review this content. You are responsible for ensuring your inputs and outputs are lawful, ethical, and appropriate for your context. - **Determining whether the Software is appropriate for your use case.** The Software is a general-purpose research tool. It is not intended for, and is not warranted as suitable for, safety-critical, life-critical, mission-critical, regulated, or production-grade environments without your own independent review, hardening, and diligence. --- ## 5. Accuracy of research output **The Software does not guarantee factual accuracy.** Research output is produced by: 1. A language model decomposing your question into sub-queries, 2. Third-party search engines ranking web pages, 3. A headless browser fetching whatever HTML those pages happen to serve, 4. A language model synthesizing an answer from that content and inventing citation numbers. Each step introduces the possibility of error. Citation numbers may be mapped to sources that do not actually support the cited claim. Sources may themselves be inaccurate, outdated, satirical, AI-generated, or deliberately misleading. The language model may hallucinate. The search engine may be biased or manipulated. **Treat all deepdive output as a research lead that needs independent verification, not as a finished answer.** --- ## 6. No support obligation The project is operated on a **best-effort, volunteer basis**. There is no obligation, express or implied, to: - respond to issues, discussions, pull requests, emails, or other communications - fix bugs, address vulnerabilities, or publish updates on any timeline - maintain backward compatibility between versions, except where explicitly stated in release notes - continue the project at all --- ## 7. No availability or continuity guarantee The Software may stop working at any time, for any reason, including but not limited to: - changes to search engines' HTML output, rate limits, or terms - changes to LLM provider APIs or authentication flows - changes to Playwright, Chromium, operating systems, runtimes, or dependencies - the project entering maintenance mode, archive status, or being discontinued You should have a fallback plan if continuous availability matters to your workflow. --- ## 8. Third-party services and content deepdive reaches out to services and web pages you or your LLM's plan selects. When you use it: - **You initiate the connection.** The project neither controls nor hosts any upstream service or content. - **You are the party contracting with each upstream service** under its terms, not through the project. - **The project does not warrant, endorse, or take responsibility for** the availability, accuracy, legality, quality, safety, or any other aspect of content, services, or responses provided by any upstream service or web page. - **The project does not process, store, or transmit your data outside of your local machine**, except insofar as it forwards your queries to the search and LLM services you configured, and fetches the URLs those services returned. --- ## 9. Credentials and local data The Software may read API keys and OAuth tokens from environment variables or CLI flags on your behalf. It does not persist credentials to disk. - You are responsible for the security of your machine, your user account, your shell history, and any system where credentials might be exposed. - The project is not responsible for credential compromise resulting from the security of your environment, your configuration choices, or third-party software running on your system. --- ## 10. Export, sanctions, regulated use The Software is distributed from the United States. You are responsible for complying with all applicable export-control laws, sanctions regimes, and regulations in your jurisdiction. The Software is **not designed, tested, or warranted for use** in environments requiring specific regulatory certifications (HIPAA, PCI-DSS, FedRAMP, SOC 2, ISO 27001, FDA, FAA, NERC-CIP, etc.). If your use falls under such a regime, you are solely responsible for determining suitability and performing any required controls, audits, or risk assessments. --- ## 11. Indemnification To the maximum extent permitted by applicable law, you agree to indemnify, defend, and hold harmless the authors, maintainers, contributors, and copyright holders of the Software from and against any and all claims, damages, losses, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or in connection with: - your use of the Software - your violation of any third-party terms, policies, or agreements (including search-engine or site-operator terms) - your violation of any law or regulation - your violation of any third-party right, including privacy, publicity, or intellectual property rights - any content you transmit through, cause to be fetched by, or cause to be produced by the Software --- ## 12. Changes to this disclaimer This document may be updated from time to time. Changes take effect on the date shown at the top of the file. Continued use of the Software after a change indicates acceptance of the updated disclaimer. --- ## 13. Governing law and severability This disclaimer is to be interpreted consistently with the MIT License. If any provision is held to be unenforceable under applicable law, the remaining provisions remain in full force and effect, and the unenforceable provision shall be modified to the minimum extent necessary to make it enforceable while preserving its intent. --- ## 14.
