0.7.0 (Tauri Migration) Will be released by the end of May (5/31), Currently cleaning up the code and adding new features

A powerful native desktop document editor with AI-driven writing assistance, git-like version control, real-time collaboration, and an extensible plugin ecosystem. Perfect for writers, developers, and knowledge workers who need intelligent document composition with full revision history.

Lexicon merges the simplicity of a word processor with the power of AI agents, version control, and collaborative editing—all in a native, fast desktop application.

• AI-Powered Writing — Grammar checking, context-aware suggestions, readability analysis, tone detection, and inline Copilot-style ghost text suggestions (Tab to accept, Escape to dismiss) with auto-dismiss on cursor move
• Right-Click Context Menu — Copy, Cut, Paste, Select All, Add Comment, Synonyms (AI), and Translate to any of 23 languages directly from the editor
• Rich Document Editing — Full WYSIWYG with TipTap: headings, lists, tables, images, links, footnotes, page breaks, alignment, font family/size/color, background colors
• Git-like Version Control — Commits, branches, merge with conflict detection, tags, cherry-pick, interactive rebase (squash/reorder/edit), blame view, stash, patch export/import, DAG graph, VCS hooks
• Persistent AI Sessions — Multi-agent support (Writer + Reviewer), web search, outline generation, summarization, 23-language translation, style refinement
• Rust Native Backend — Optional Rust (napi-rs) addon for accelerated document processing, PDF export, document analysis, and search
• Real-Time Collaboration — Yjs CRDT over WebSocket, shared cursors with colored indicators, room codes, presence awareness, live document sync
• Document Intelligence — Inline version diff, table of contents, print preview with headers/footers, comment threads, track changes, autocorrect (typos, smart quotes, em-dash)
• Plugin Ecosystem — Sandboxed runtime, 5 lifecycle hooks, per-permission API, built-in marketplace (word frequency, Pomodoro timer, MD paste sanitizer)
• Export & Import — DOCX, HTML, Markdown, PDF, EPUB with formatting preservation
• Dark & Light Themes — Catppuccin Mocha/Latte, Dracula, Nord, Solarized Dark/Light with custom accent colors
• Auto-Update — Built-in update checking with GitHub releases integration
