Your AI tools are powerful. But they're flying blind.
Cursor, Claude Code, Windsurf, Antigravity - they can write great code. But they don't truly know your codebase structure.

Agentic AI Tools vs Grapuco
Traditional agents rely on iterative text searches (grep/find) and guessing to build context. Grapuco precomputes the entire code structure-clustering, tracing, and scoring-delivering complete, precise context in a single call.
Traditional AI Agents
LLM triggers CLI to search files
Step 1: Read files to find callers
Step 2: Missing context, search again
Step 3: Read more files, hit token limits
Step 4: Attempt to synthesize logic
Answer after multiple slow iterations
Grapuco Smart Graph
Query: Impact of UserService upstream?
Pre-structured: 8 callers, 3 clusters, 90%+ confidence
Complete and accurate answer, 1 query
Core Innovation: Precomputed Relational Intelligence
Reliability - LLM can't miss context, it's already in the tool response
Token efficiency - No 10-query chains to understand one function
Model democratization - Smaller LLMs work because tools do the heavy lifting
How It Works
Grapuco builds a complete knowledge graph of your codebase through a multi-phase indexing pipeline:
Structure
Walks the file tree and maps folder / file relationships
Parsing
Extracts functions, classes, methods, and interfaces using Tree-sitter ASTs
Resolution
Resolves imports, calls, heritage, constructor inference across files
Clustering
Groups related symbols into functional communities
Processes
Traces execution flows from entry points through call chains
Search
Builds hybrid search indexes for fast retrieval
Deep AST Parsing
Our proprietary engine deconstructs your codebase into its foundational tokens. We don't just read text; we understand the hierarchical structure of your logic.
Semantic Search
Vectorized symbols with pgvector for natural language code querying. Find logic, not just strings.
Data Flow Detection
Automatically trace execution paths from API endpoints down to database models across diverse frameworks like Express, Spring Boot, Laravel, and Prisma.
MCP Server Protocol
Native integration with Claude, Cursor, and Windsurf via the Model Context Protocol. Plug in your knowledge graph directly.
AI Context Enrichment
Powered by Embedding Models. We execute deep process detection and semantic community enrichment to give your AI agents the global context they lack.

What can you do with Grapuco?
Real scenarios, real answers. Ask a question, get complete context instantly.
"I need to change the login function. What will break?"
- Login handler
- Registration handler
- User controller
- Auth router
Grapuco instantly maps every function, file, and flow that depends on your change - before you make it.
"Where is the authentication logic in this project?"
- validateUser β checkPassword β createSession β ...
- registerUser β sendOTP β verifyEmail β ...
Instead of random file matches, you get complete execution flows grouped by business process.
"Tell me everything about the validateUser function."
- handleLogin
- handleRegister
- UserController
- checkPassword
- createSession
- LoginFlow (step 2/7)
- RegistrationFlow (step 3/5)
Full relationship map: who calls it, what it calls, and which business flows it belongs to.
"I changed 4 files today. Is it safe to commit?"
- 12 symbols across 4 files
- LoginFlow affected
- RegistrationFlow affected
- PaymentFlow OK
Know the blast radius of every commit before it ships. No more surprise breaking changes.
"How does data trace from this API endpoint to the database?"
- POST /api/users/register
- AuthService β EmailService β DBRepository
- UserModel
- AuditLog
Automatically trace data flow from HTTP routes down to DB models across frameworks like Express, NestJS, and Prisma.
"Write specifications for a new payment processing module."
- Stripe webhook must be idempotent
- Log to Audit Table
- Payment Webhook β Verification β TransactionDB
- Returns 200 OK
- Handles timeout gracefully
