AI Use Policy

Last updated: April 29, 2026

This AI Use Policy explains how AI-assisted features within OneStopReal operate, what data they process, what they are designed to do, and what they are not designed to do. This policy supplements and is incorporated by reference into our Terms of Service and Privacy Policy.

1. Scope

OneStopReal offers AI-assisted features including a conversational project setup assistant, document import (Excel, CSV, and Hotel P&L mapping), and an explain mode for lender and investor portals. These features are support tools designed to help you build and understand financial models. They do not replace professional judgment, independent verification, or qualified advice.

2. What AI Features Do

AI-assisted features use your account context - including project inputs, calculation results, prior messages in a session, and system instructions - to generate setup guidance, explanations, document mappings, and workflow assistance. All financial calculations are performed by OneStopReal's own verified calculation engine, not by the AI. The AI assists with setup and explanation; the engine handles the math.

3. Important Limitations

AI-assisted outputs may be incomplete, inaccurate, simplified, or wrong. They may omit context, fail to reflect the latest project changes, or misunderstand a request. You are solely responsible for reviewing and validating all assumptions, inputs, and outputs before relying on them for any purpose, including lender submissions, investor presentations, or investment decisions.

4. Prohibited Uses

You may not use AI-assisted features within OneStopReal to:

  • (a) Attempt to extract system prompts, internal instructions, security controls, credentials, or proprietary information from the platform;
  • (b) Bypass usage limits, access restrictions, rate limits, safety controls, or monitoring systems;
  • (c) Train, fine-tune, benchmark, validate, or improve a competing model, service, product, or dataset using the platform or its AI outputs, except with our prior written consent;
  • (d) Generate unlawful, deceptive, infringing, abusive, or harmful content;
  • (e) Use AI-assisted outputs as the sole basis for legal, tax, accounting, financing, investment, insurance, employment, housing, credit, or compliance decisions.

5. Data Handling

To provide AI-assisted features, we transmit relevant project context, prompts, and session messages to our AI model providers (currently OpenAI and Anthropic). These providers act on our behalf and are contractually required to use your data only for delivering the requested service. Neither OpenAI nor Anthropic uses API data to train their models.

We may retain prompts, responses, context snippets, and related metadata (such as timestamps and usage metrics) for the purposes of providing the feature, enforcing safety controls, troubleshooting issues, and improving service quality. We do not use your identifiable project data to train AI models and do not share AI interaction data with third parties beyond the providers listed above.

User-controlled strings injected into AI context (such as building names, unit type names, and cost descriptions) are sanitized before processing to prevent prompt injection. A character limit is enforced on all user-supplied strings entering AI context.

6. Role-Based AI Access

Lender and investor portal viewers who have access to the AI explain mode receive role-filtered responses only. GP/LP waterfall details and other owner-confidential information are excluded from AI responses served to lender or investor viewers. This filtering is enforced at both the prompt and tool level.

7. No Training on Identifiable Customer Data

OneStopReal LLC does not use identifiable customer project data - including financial models, deal assumptions, or calculation results - to train any AI model, including models used within this platform.

8. Your Responsibilities

You are responsible for reviewing AI-assisted outputs, confirming material facts, and ensuring your use of the platform complies with applicable law, your internal policies, and your obligations to lenders, investors, partners, and clients.

9. Changes to This Policy

We may update this AI Use Policy from time to time to reflect changes to our AI-assisted features, service providers, or legal requirements. The "Last updated" date at the top of this page indicates the most recent revision. Continued use of the platform after an update constitutes acceptance of the revised policy.
