Score: 4.5/10 (Innovation: 5, Technical: 5, Documentation: 4, Utility: 4)

Glyph is an experimental byte-exact substring retrieval engine using FM-index for fast exact matching at scale, bypassing tokenization and ranking. Its innovative approach targets niche use cases like binary log search and forensic analysis, but the minimal documentation and lack of pre-built artifacts limit its immediate utility.

Target audience: backend devs, data engineers
