Terms of service

Last updated: April 9, 2026

These Terms of Service ("Terms") govern your access to and use of Parallax ("the Service"), operated by Three Sons LLC ("we," "us," or "our"). By creating an account or using the Service, you agree to be bound by these Terms. If you do not agree, do not use the Service.

1. Eligibility

You must be at least 18 years old to use the Service. By creating an account, you represent and warrant that you are at least 18 years of age.

2. Service description

Parallax is a thinking workspace offering three primary modes of interaction:

  • Riff mode: Fast single-AI conversation for brainstorming and exploration
  • Debate mode: Multiple model perspectives analyze a query through multiple rounds of debate, producing a synthesized conclusion
  • Build mode: AI-generated deliverables including documents, spreadsheets, presentations, code, and other files based on the thread context

Users may upload documents and files for AI analysis. Uploaded content is processed under the same Zero Data Retention policy as text queries.

Session limits, AI model access, and feature availability vary by subscription tier as described on the pricing page.

The Service depends on third-party AI providers (such as Anthropic, OpenAI, Google, xAI, and Mistral), third-party infrastructure services (Supabase, Stripe, E2B), and either our managed API access or user-provided API keys to function.

3. User accounts

You are responsible for maintaining the confidentiality of your account credentials and for all activities that occur under your account. You must provide accurate, current, and complete information during registration. You agree to notify us immediately of any unauthorized use of your account.

4. Data processing and retention

Parallax processes user queries through third-party AI model providers via Vercel's AI Gateway with Zero Data Retention enabled. Under this configuration, user inputs and AI outputs are not stored at rest by AI providers after the response is returned, except where required by law or to enforce usage policies.

Parallax stores conversation history, account information, and usage data on our servers to provide the service. Users may delete their conversation history at any time from their dashboard.

Parallax does not sell, share, or provide user data to third parties for advertising, marketing, or model training purposes.

Users are responsible for ensuring their use of the service complies with any industry-specific regulations that apply to them (such as HIPAA, SOX, GDPR, etc.). Parallax provides zero data retention as a technical measure on supported routes but does not guarantee compliance with any specific regulatory framework.

5. AI-generated content

Parallax provides AI-generated responses for informational purposes. Outputs from the service, including but not limited to financial analysis, legal commentary, medical information, and business strategy, should not be treated as professional advice. Users should consult qualified professionals before making decisions based on AI-generated content.

Parallax is not responsible for the accuracy, completeness, or applicability of AI-generated responses. Multiple model perspectives may disagree, and the final output represents a synthesis of perspectives rather than a guarantee of correctness.

AI-generated code executed in the sandbox environment runs in an isolated container. However, we make no warranties about the security, correctness, or safety of generated code. You download and use generated files at your own risk.

6. API access and key provisions

6.1 Managed subscription tiers (Explorer, Starter, Pro, Unlimited)

For managed subscription tiers, AI API calls are routed through our provider accounts. You do not need to provide your own API keys. API access costs are included in your subscription fee. We reserve the right to modify which AI models are available on each tier, adjust session limits, and route requests through different model versions at our discretion. You acknowledge that AI responses may vary based on model availability and provider status.

AI model selection and routing: Parallax uses query routing to manage performance and platform capacity. Queries may be routed to equivalent models within the same provider family based on query complexity and your subscription tier. The specific model version used may differ from the model displayed in the interface. Higher-tier subscriptions may unlock access to premium model versions for more complex queries. Model availability, versions, and routing logic may change at any time without notice as providers update their offerings.

6.2 Bring your own key (BYOK) tier

The BYOK tier requires you to provide your own third-party API keys (e.g., from Anthropic, OpenAI, Google, xAI, Mistral) to access AI functionality.

Key storage: Your API keys are encrypted at rest using AES-256-GCM encryption and are transmitted exclusively over TLS. We never log, display, or use your API keys for any purpose other than executing requests on your behalf during active Parallax sessions.

Your responsibilities: You are solely responsible for:

  • The validity, security, and billing of your third-party API keys
  • Compliance with each third-party provider's terms of service
  • All costs incurred through API calls made via the Service using your keys
  • Rotating or revoking compromised keys promptly

Our liability limitations: WE DISCLAIM ALL LIABILITY for charges incurred on your third-party accounts, service disruptions caused by invalid, expired, or rate-limited keys, actions taken by third-party AI providers regarding your data, and output generated by third-party AI models.

6.3 Shared provisions

Regardless of your subscription tier, all AI-generated output is subject to the disclaimers in Section 5. We do not control the AI models, their outputs, or their data handling practices.

7. Subscription and billing

Parallax offers multiple subscription tiers billed monthly through Stripe. Current tiers and pricing are listed on the pricing page and may change with notice to subscribers.
