SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Locating and recalling relevant documents and contextual knowledge across a desktop workspace can be time-consuming and error-prone when relying on manual file browsing or scattered notes. This Skill provides a local semantic search capability that indexes text across files and agent memory, enabling fast, natural-language retrieval without sending data to the cloud.

Core Features & Use Cases

  • Local, offline semantic search over desktop files and agent memory using BM25 + embeddings for relevance-aware results.
  • Supports a wide range of formats (PDF, DOCX, XLSX, PPTX, HTML, EML, JSON, CSV, code, and plain text) with deterministic chunking and instant re-indexing.
  • Use cases include quickly locating a document, surfacing background knowledge for an AI assistant, and auditing information across your knowledge base without leaving your device.

Quick Start

Index a directory and start searching with natural language queries.

FAQPage Schema
How do I do offline semantic search on local desktop files?

Offline semantic search on local desktop files is done by indexing directories with a local engine that uses BM25 and embeddings, enabling fast natural-language retrieval without internet access.

Can I index and search PDF and DOCX files locally?

Yes, you can index and search PDF and DOCX files locally. The semantic search engine supports a wide range of formats including XLSX, PPTX, HTML, JSON, CSV, and code for context-rich retrieval.

What is the best way to provide agent memory for an AI assistant?

Providing agent memory for an AI assistant is best done by indexing contextual knowledge and local desktop files into an offline semantic search engine, allowing the assistant to surface background information quickly.

Does local semantic search work without an internet connection?

Yes, local semantic search works entirely offline. It enforces safe, offline operation with configurable embedding providers to ensure your desktop files and agent memory stay on your device.

How do I keep search results consistent when re-indexing local documents?

To keep search results consistent when re-indexing local documents, the semantic search engine uses deterministic chunking and a frontmatter-driven discovery model to maintain index and search alignment.
