How we're building indexes for regular expression search so agents can find text in large monorepos without the 15-second ripgrep waits.
Semble: Fast and Accurate Code Search for Agents
Fast and Accurate Code Search for Agents. Uses ~98% fewer tokens than grep+read
RegExr: Learn, Build, & Test RegEx
RegExr is an online tool to learn, build, & test Regular Expressions (RegEx / RegExp).
Meilisearch: Unified Search & AI Retrieval Platform
