Show HN: Mantic.sh – Search 480k files in 0.46s without embeddings

Summary

Mantic A structural code search engine for AI agents. Provides sub-500ms file ranking across massive codebases without embeddings, vector databases, or external dependencies. What's New in v1.0.12 Critical Fix : Implemented missing high-confidence scoring path in scanProjectLegacy that was causing "Scanner failed to produce scored files" error : Implemented missing high-confidence scoring path in scanProjectLegacy that was causing "Scanner failed to produce scored files" error Proper Scoring : All queries now receive proper scores from BrainInspiredScorer regardless of intent confidence level : All queries now receive proper scores from BrainInspiredScorer regardless of intent confidence level Reliability: Fixed the root cause of undefined scoredFiles that was triggering the broken fallback in v1.0.10 Table of Contents About the Project Mantic is an infrastructure layer designed to remove unnecessary context retrieval overhead for AI agents. It infers intent from file structure and metadata rather than brute-force reading content, enabling retrieval speeds faster than human reaction time. Key Benefits Speed : Retrieval is consistently under 500ms, even for large repositories. : Retrieval is consistently under 500ms, even for large repositories. Efficiency : Reduces token usage by up to 63% by filtering irrelevant files before reading. : Reduces token usage by up to 63% by filtering irrelevant files before reading. Privacy: Runs entirely locally with zero data egress.
