Welcome to Cortex. The Cortex application and related services (collectively, the "Service") are provided by the individual developers known as Vertex ("we," "us," or "our"). These Terms of Service ("Terms") govern your access to and use of the Cortex Service specifically.
These Terms supplement and are incorporated by reference into the general Vertex Terms of Service, which govern the entire Vertex ecosystem. By creating an account or using our Service, you agree to be bound by both these Cortex-specific Terms, the general Vertex Terms, and the Cortex Privacy Policy.
Cortex provides access to a variety of third-party artificial intelligence models for conversational purposes. The Service is offered through both free and paid tiers. Your access to and use of the Service is conditioned on your acceptance of and compliance with these Terms.
You must create a Vertex Account to use most features of Cortex. You are responsible for all activities that occur under your account and for keeping your password confidential and secure. You agree to notify us immediately of any unauthorized use of your account.
Cortex may offer paid subscriptions and a digital credit system ("Credits") to access premium features or online models. Credits are specifically required to interact with online AI models. All financial transactions are processed through third-party payment gateways like the Google Play Store or Apple App Store.
You are solely responsible for your conduct and any content you submit or generate using the Service ("User Content"), which includes both the messages in your conversations and the custom AI models you create. To maintain a safe and respectful environment, especially considering our diverse user base which includes younger audiences, you agree not to use the Service for any purpose that is illegal or prohibited by these Terms.
To enforce these rules, we employ safety mechanisms for both online and offline models. For online models, your inputs and custom model configurations may be submitted to automated content moderation services like OpenAI's Moderation API. For offline models, the app performs a similar check locally on your device using a set of rules periodically downloaded from our servers, as detailed in our Privacy Policy. In both cases, these checks are automated and designed to prevent the generation of harmful content. You agree that you will not generate or disseminate User Content that:
We reserve the right, but have no obligation, to monitor, filter, and remove User Content that we determine, in our sole discretion, violates these Terms or is otherwise harmful to our Service or our users. We may also suspend or terminate your account for violations of this policy.
We empower our users to help us maintain a safe and responsible environment. If you encounter any AI-generated content that you believe violates our policies or is otherwise harmful, you agree to report it. You can do this by using the in-app reporting feature, which is accessed by long-pressing the specific message in a conversation. When you submit a report, you acknowledge that this action will transmit the necessary data for our review. The specific details of the data collected during this process are outlined in the "Handling of User Reports and Content Moderation" section of our Privacy Policy. We are committed to investigating these reports promptly to take appropriate action.
The Service provides access to experimental AI technologies. Your use of these features is entirely at your own risk.
While we implement automated safety filters and establish clear content policies, you acknowledge that generative AI is an evolving technology and may, in rare and unintended instances, produce outputs that are inconsistent with our policies. We are committed to continuously improving our safety mechanisms and promptly addressing any reported issues to mitigate such occurrences.
The Cortex client application is open-source software. You may download, modify, and distribute the source code in accordance with the license specified in the GitHub repository. However, these Terms of Service apply only to the official Service provided by Vertex. We are not responsible or liable for any self-hosted, modified, or third-party versions of the application.
In addition to our own code, the Service incorporates various third-party assets, including but not limited to fonts, icons, and AI models, which are provided under their own respective licenses. A comprehensive list of these assets and their required attributions can be found on our Attributions Page. By agreeing to these Terms, you also agree to be bound by the terms of these third-party licenses.
THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL THE DEVELOPERS OF VERTEX, THEIR AFFILIATES, OR PARTNERS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS OR REVENUES, WHETHER INCURRED DIRECTLY OR INDIRECTLY, OR ANY LOSS OF DATA, USE, GOODWILL, OR OTHER INTANGIBLE LOSSES, RESULTING FROM: (A) YOUR ACCESS TO OR USE OF OR INABILITY TO ACCESS OR USE THE SERVICE; (B) ANY CONDUCT OR CONTENT OF ANY THIRD PARTY ON THE SERVICE; (C) ANY CONTENT OBTAINED FROM THE SERVICE; OR (D) UNAUTHORIZED ACCESS, USE, OR ALTERATION OF YOUR TRANSMISSIONS OR CONTENT.
We may terminate or suspend your account and bar access to the Service immediately, without prior notice or liability, for any reason whatsoever, including without limitation if you breach the Terms. We also reserve the right to modify or discontinue the Service at any time.
These Terms shall be governed and construed in accordance with the laws of the Republic of Turkiye, without regard to its conflict of law provisions. You agree to submit to the exclusive jurisdiction of the Istanbul Central (Çağlayan) Courts to resolve any legal matter arising from the Terms.
These Terms constitute the entire agreement between you and Vertex regarding our Service. Our failure to enforce any right or provision of these Terms will not be considered a waiver of those rights. If any provision is held to be invalid, the remaining provisions will remain in effect.
We reserve the right, at our sole discretion, to modify or replace these Terms at any time. We will indicate any changes by updating the "Last Updated" date at the top of these Terms. For any significant changes, we will provide a more prominent notice. Your continued use of the Service following the posting of any changes to these Terms constitutes acceptance of those changes.
