BY CREATING AN ACCOUNT, DOWNLOADING THE APP, OR OTHERWISE USING THE SERVICES, YOU AGREE TO BE BOUND BY THESE TERMS. IF YOU DO NOT AGREE, DO NOT USE THE SERVICES.

If you are using the Services on behalf of an organization, you represent and warrant that you have the authority to bind that organization to these Terms.

3. The Services

3.1 Description

Node Architect is an AI-powered tool that analyzes software project architectures and generates interactive dependency graphs. The Services include: (a) The Platform — web-based account management, usage analytics, billing, and API key management. (b) The App — a desktop application that connects to the Node Architect API or directly to third-party LLM providers to perform project analysis. (c) The API — a server-side interface that processes analysis requests, manages sessions, and tracks token usage.

3.2 Service Modes

The App operates in two modes:

• NodeArchitect API Mode — analysis requests are routed through our API servers. Token usage is tracked and deducted from your account balance.
• Direct LLM Mode — analysis requests are sent directly from the App to your chosen LLM provider (Anthropic or OpenAI) using your own API key. In this mode, cileria does not process your Content, does not track token usage, and bears no responsibility for the interaction between you and the LLM provider.

3.3 AI-Generated Output

Analysis results, architecture graphs, node summaries, and edge analyses are generated by artificial intelligence and are provided on an “AS IS” basis. You acknowledge that: (a) AI-generated output may be inaccurate, incomplete, or misleading. (b) You are solely responsible for reviewing, validating, and deciding whether to rely on any AI-generated output. (c) cileria does not warrant the correctness, reliability, or fitness of AI-generated output for any particular purpose.

4. Account Registration and Security

• You may register using email and password or Google OAuth2. Email registrations require email verification before the account becomes active.
• Each individual may maintain only one active account. We reserve the right to merge or terminate duplicate accounts.
• Your API Key is equivalent to a password. You must keep it confidential, not embed it in publicly accessible code, and regenerate it immediately if you suspect it has been compromised.
• You are liable for all token usage incurred through your API Key, regardless of whether such usage was authorized by you.
• We may suspend or terminate your account immediately and without prior notice if we reasonably believe you are violating these Terms, engaging in fraudulent activity, or posing a security risk to the Services.
