GlyphSift is an independent, browser-local Copy-Paste Text Studio for styling, cleaning, inspecting, and cautiously previewing Unicode text.
GlyphSift combines deterministic text transformations with visible coverage, character-level inspection, and evidence-aware compatibility language. The project does not use AI to rewrite tone or meaning. Expression rewriting belongs to SayMorph; GlyphSift changes representation and structure.
The engine ships with a deterministic test suite of over 100 cases across eight node:test suites, run after each production build with no network access and no randomness.
Suites cover tool contracts and character coverage, cleanup and transform edge cases, Unicode inspection, compatibility-risk detection, and server-rendered HTML. Behavior is derived from the published Unicode standards (UAX #9, #15, #29; UTS #39) and RFC 3629 for UTF-8.
