Frequently Asked Questions
What is GRID Analyzer?
GRID Analyzer is a privacy-first, local-first tool that helps you understand any codebase in minutes. It uses local AI models to analyze code, map relationships, and answer questions—all without sending your code to external APIs. Everything runs on your machine.
How is this different from GitHub Copilot?
Copilot helps you write code. GRID helps you understand code. Copilot suggests next lines; GRID analyzes entire codebases, maps relationships, and answers questions about architecture and dependencies.
Does my code really stay local?
Yes. GRID runs entirely on your machine using local AI models. Zero network requests. No API keys needed. Your code never leaves your computer. You can even run it offline.
What programming languages do you support?
Python, JavaScript/TypeScript, Java, Go, Rust, C/C++, Ruby, PHP, C#. More languages coming based on community demand. The semantic analysis works across any language.
How fast is the analysis?
Initial indexing: ~1-5 minutes for 1M lines of code. Subsequent queries: near-instant (under 1 second). Incremental updates are fast (only reindex changed files).
What are the system requirements?
Minimum: 8GB RAM, 2GB disk space. Recommended: 16GB RAM, SSD. Works on Windows, Mac (Intel/M1), and Linux. Python 3.9+ required.
Can I try it before buying?
Absolutely! Free tier available for projects up to 10K files. Professional tier includes 7-day free trial (no credit card required). 30-day money-back guarantee on all paid plans.
What makes GRID unique?
Five key differentiators: (1) Local-first architecture—built from the ground up, not retrofitted. (2) 9 Cognition Patterns—unique framework for understanding complex systems. (3) Cognitive decision support—adapts to your behavior. (4) Production-grade security—10+ security layers. (5) State-of-the-art RAG—33-40% better precision than standard search.
What problems does GRID solve?
Three critical pain points: (1) Productivity—developers spend 40% of their time understanding code; GRID reduces this to minutes. (2) Privacy/compliance—most AI tools require sending code to external APIs; GRID processes everything locally. (3) Semantic understanding—text search can't answer "why" or "how" questions; GRID uses semantic analysis to understand code structure.
Who is GRID for?
Four key segments: (1) Regulated industries—healthcare, finance, government that can't use cloud AI tools. (2) Privacy-conscious developers—concerned about AI data usage. (3) Offline environments—air-gapped systems requiring offline operation. (4) Individual developers—priced out of enterprise tools but need professional-grade understanding.
What are GRID's 9 Cognition Patterns?
A unique framework for understanding complex systems: Flow (data pipelines), Spatial (architecture), Rhythm (timing), Color (categorization), Repetition (patterns), Deviation (anomalies), Cause (relationships), Time (evolution), and Combination (integration). This framework is unique to GRID—no competitor has this cognitive architecture.
How does GRID adapt to my cognitive state?
GRID uses a Coffee House Metaphor for cognitive load management: Espresso mode (focused, 32-char chunks), Americano mode (balanced, 64-char chunks), and Cold Brew mode (comprehensive, 128-char chunks). It automatically detects your cognitive load and adapts responses accordingly.
What research has GRID contributed?
Several novel discoveries: (1) Temporal Resonance with Q Factor—temporal reasoning in RAG systems inspired by audio engineering. (2) Boundary Contracts—OS-level safety with formal ownership transfer. (3) Adaptive Intelligence Framework—7-step learning cycle with 8.5/10 research merit rating. These are implemented in production code, not just papers.
What is GRID's architecture?
GRID follows a layered, domain-driven architecture with six layers: Entry Points, Application, Domain Services, Core Intelligence, Infrastructure, and Data. Unlike typical tools that operate at a single level, GRID implements multiple interacting cognitive layers—creating a model closer to human cognition than standard software architecture.
Is GRID's architecture original?
GRID is neither a clone nor a standard implementation. While it draws inspiration from established patterns (seL4, Fuchsia, Rust ownership, cognitive science), it synthesizes these into something distinctly its own. The 9 Cognition Patterns framework and Geometric Resonance metaphor are proprietary innovations. GRID represents thoughtful synthesis—a custom definition that evolved organically through principled experimentation.
How do I get support?
Free tier: Community forums. Professional: Email support (48h response). Team: Priority email (24h). Enterprise: Dedicated support (4h SLA) + success manager.
What if I'm not satisfied?
30-day money-back guarantee. No questions asked. Cancel anytime—no long-term contracts.

Read article →The Story Behind GRID
Built with care, not just code
How It Started
GRID began in late November 2025 with a simple commit: "finance & science." The first files were experiments—blank templates, empty idea journals. Someone figuring things out, not sure where it was going.
By early December, something shifted. A journal entry titled "The Art of Detangling" described discovering that the UI was being imported everywhere—"a classic architectural sin." That's when it stopped being just code and started becoming a System.
What We Believe
Most AI tools pretend to know everything. We built GRID to be honest about what it doesn't know. There's a state in our pattern engine called "MIST"—for when the system detects something important but can't explain it. The code comment says: "High confidence that we DON'T know."
We spent time studying Carl Jung's psychology to understand epistemic humility—the idea that admitting "I don't know" is sometimes the smartest answer. That thinking shaped everything we build.
The "No Matter" Principle
Our core design principle: When the environment is noisy or overwhelming, separate signal from noise, compress it into a structured core, and keep moving. That's not from a textbook. It's from dealing with chaos and figuring out how to work through it.
Being Real
An independent reviewer gave us a 9.2/10 for work ethics, noting: "Honest acknowledgment of remaining failures. Clear distinction between what was fixed vs what needs work."
We're not perfect—early on, 29 tests were still failing. But we documented every fix, reported actual numbers instead of rounding up, and never claimed something worked until it actually did.
The Journey
GRID isn't a corporate project with twenty engineers. It's built by someone who cares about doing things right—principled, not perfect. And that difference matters.
