Sensegrep for VS Code

Semantic + structural code search with AI-powered duplicate detection.

Search your codebase by meaning, not just text. Sensegrep uses AI embeddings and tree-sitter AST parsing to find conceptually relevant code.

Features

Semantic Search - Natural language queries to find relevant code
Survey & Cluster - Map a code domain or split a broad theme into related subtopics
Find Similar Code - Select code and find similar patterns across your project
Duplicate Detection - AI-powered detection of logical duplicates with impact scoring
Structural Filters - Filter by symbol type, exports, async, complexity, language, decorators, and more
Tree-Shaking - Results collapse irrelevant code, showing only what matters
Code Lens - Inline Find Similar actions
Auto-Indexing - Automatic incremental index updates on file changes
Semantic Folding - Collapse unrelated code when navigating to results
Config-first Embeddings - Share ~/.config/sensegrep/config.json with CLI and MCP

Supported Languages

TypeScript / JavaScript (TSX/JSX)
Python (dataclasses, protocols, decorators, async generators, TypedDict)
Java (classes, interfaces, records, annotations, methods)
Vue (single-file components with script and script setup support)

Configuration

Setting	Default	Description
`sensegrep.autoIndex`	`false`	Index project when Sensegrep activates
`sensegrep.watchMode`	`true`	Auto-reindex on file changes
`sensegrep.watchIntervalMs`	`60000`	Min interval between reindexing (ms)
`sensegrep.includeDocs`	`false`	Include Markdown/documentation files in the index
`sensegrep.includeConfig`	`false`	Include JSON/YAML/TOML config files in the index
`sensegrep.showCodeLens`	`true`	Show inline Find Similar actions
`sensegrep.showDiagnostics`	`true`	Show duplicate warnings in Problems panel
`sensegrep.semanticFolding`	`true`	Collapse unrelated code on navigation
`sensegrep.duplicateThreshold`	`0.85`	Similarity threshold for duplicates
`sensegrep.embeddings.provider`	`config`	`config`, `gemini`, `openai`, or `bedrock`
`sensegrep.embeddings.model`	empty	Embedding model override

Embeddings Configuration

By default, the extension uses the same configuration as the CLI/MCP:

{
  "provider": "bedrock",
  "embedModel": "cohere.embed-v4:0",
  "embedDim": 1536,
  "region": "us-east-1"
}

Store it at ~/.config/sensegrep/config.json, or configure equivalent environment variables.

For LM Studio or another OpenAI-compatible embeddings server, set provider to openai, baseUrl to the server /v1 endpoint, and embedModel/embedDim to the running embedding model.

For Gemini, set sensegrep.embeddings.provider to "gemini" and run Sensegrep: Set Gemini API Key or set GEMINI_API_KEY.

For Amazon Bedrock, set provider to bedrock in config.json or set sensegrep.embeddings.provider to "bedrock" and configure credentials/region through the standard Bedrock setup.

Development

npm run check --workspace sensegrep
