+Cross-platform document editor with format tabs (TXT/MD/ADOC/DJOT/ORG/RST/TYP). Gossamer GUI + Ada TUI. Graph visualization, OCR, TTS/STT, Nickel pipelines.
+
+== Features
+
+* *Format Tabs* - View and edit the same document in multiple markup formats
+* *Unified AST* - Lossless conversion between formats
+* *GUI* - Gossamer with ReScript frontend
+* *TUI* - Ada with AdaCurses for terminal usage
+* *Graph Visualization* - ArangoDB for document relationships
+* *Accessibility* - OCR, TTS, STT support
+* *Pipelines* - Nickel-based import/export transformations
