XERJ is the new way for AI to search data. Its autoindex capability activates agents to know your data without the token waste of grep (1974 tool). One command indexes code, docs, logs and PDFs for search, RAG, security audits and agent memory, using 40x fewer tokens than grep. It’s durable and can replace ElasticSearch saving you x10 infra costs.
XERJ is a local search tool that automatically indexes folders so coding agents can retrieve relevant code, documents, logs, and PDFs without reading files one at a time. It is for developers and agents using code search, retrieval-augmented generation, security audits, or agent memory.
This repository also configures its own agents. See what xerj tells them →

Coverage-guaranteed whitebox security audit of a codebase using XERJ + tree-sitter AST. Use when the user wants to security-review PHP (or other-language) code with a provable "we enumerated every dangerous call" guarantee, or asks to run the WordPress-style sink census / audit. Drives an index-once, query-read-reason…

Reference-coding with XERJ. Clone the libraries that already solved your problem, index them locally, and retrieve the exact implementation before writing code — so the agent reads passages instead of re-deriving algorithms across retry loops. Use when starting a task in an unfamiliar API, porting an algorithm, or…
