Overview

Description

GZOO Cortex is a local-first knowledge graph designed for developers. It automatically monitors your project files (markdown, TypeScript, JavaScript, JSON, YAML), uses LLMs to extract key entities like architectural decisions, patterns, components, dependencies, and constraints. It then infers relationships between these entities across all your projects, detects contradictions in architectural decisions, and allows you to query your codebase in natural language with source citations. Cortex integrates directly with Claude Code via the Model Context Protocol (MCP) and supports multiple LLM providers (Anthropic Claude, Google Gemini, Ollama for local use) with intelligent routing modes (cloud-first, hybrid, local-first, local-only). It offers a web dashboard for knowledge graph visualization and query exploration.

Strengths
  • Automatic project file monitoring and entity extraction via LLMs.
  • Relationship inference and contradiction detection across projects.
  • Natural language queries with source citations for better code understanding.
  • Support for multiple LLM providers, including local options (Ollama).
  • Integration with Claude Code via Model Context Protocol (MCP).
Weaknesses
  • Requires initial setup and LLM provider configuration.
  • Extraction quality depends on the LLMs used.
  • May consume system resources, especially with large projects or local LLMs.
  • API key management and LLM costs need to be considered.

Use cases

Solopreneur managing multiple client projects

Independent developer, consultant

For solopreneurs managing multiple client projects, GZOO Cortex enables them to maintain a unified understanding of all project decisions and dependencies. Example: A consultant can query Cortex to recall the specific authentication strategy implemented for Client A's project, preventing redundant research and ensuring consistency across client work.

Developer onboarding to a large codebase

New team member, junior developer

For new team members joining a large project, GZOO Cortex facilitates rapid understanding of architectural decisions and component relationships. Example: A junior developer can ask Cortex 'What are the main components responsible for user authentication?' and receive a synthesized answer with links to relevant code files, accelerating their onboarding process.

Maintaining architectural consistency across microservices

Software architect, lead engineer

For software architects overseeing multiple microservices, GZOO Cortex helps detect and resolve architectural contradictions before they become major issues. Example: Cortex can flag a situation where two different services are configured to use incompatible database versions, allowing the architect to address the conflict proactively.

Student organizing research and project notes

Computer science student, researcher

For computer science students managing multiple academic projects and research notes, GZOO Cortex allows them to build a personal knowledge graph for easy retrieval of information. Example: A student can query Cortex about 'all patterns related to graph databases' across their project notes and code, helping them synthesize information for a thesis or complex assignment.

Frequently asked questions

How do I install GZOO Cortex?

You can install GZOO Cortex globally using npm with the command `npm install -g @gzoo/cortex`. Alternatively, you can clone the repository, build it from source, and then link it locally.

Is GZOO Cortex free?

GZOO Cortex itself is open-source and free to use under the MIT License. However, using cloud-based LLM providers for entity extraction and querying may incur costs depending on your usage and chosen provider.

How much does GZOO Cortex cost?

The GZOO Cortex software is free and open-source. Costs are associated with the usage of external Large Language Models (LLMs) if you choose to use cloud-based providers. You can set a monthly budget limit within the Cortex configuration to manage these potential costs.

What LLM providers does GZOO Cortex support?

GZOO Cortex supports multiple LLM providers, including Anthropic Claude, Google Gemini, DeepSeek, Groq, and any OpenAI-compatible API. It also fully supports local LLMs via Ollama, allowing for a local-only or hybrid approach.

Is GZOO Cortex secure and GDPR-compliant?

GZOO Cortex is designed with privacy in mind, storing all data locally. Files marked as 'restricted' are never sent to cloud LLMs. Sensitive files like API keys are scanned and redacted before transmission. While the tool itself is local-first, GDPR compliance would depend on how you manage your data and LLM provider choices.

What platforms does GZOO Cortex run on?

GZOO Cortex requires Node.js 20+ and is designed to run on developer machines. It is compatible with operating systems that support Node.js, typically macOS, Linux, and Windows.

What's the best alternative to GZOO Cortex?

Alternatives to GZOO Cortex depend on your specific needs. Tools like Sourcegraph offer code search and intelligence across repositories, while other local development tools might focus on specific aspects like documentation or dependency management. GZOO Cortex's unique strength lies in its local-first knowledge graph approach powered by LLMs.
