TexIt 0.1.0

0.1.0 — 2026-10-08

First public release.

Compilation

• TeX Live add-ons for the in-browser compiler, injected only when a document needs them: babel language files for
  30 languages (Spanish, Portuguese, French, German, Italian, Catalan…), IEEEtran and the newtx (Times) fonts.
• \usepackage[T1]{fontenc} without a font package selects the TeX Live set that ships cm-super automatically.
• TeX Live 2026 compiled to WebAssembly (TeXlyre BusyTeX) running in a Web Worker: pdfLaTeX, XeLaTeX and LuaLaTeX with
  BibTeX, Biber and makeindex. Package sets (basic / recommended / extra) are chosen from the packages a project uses
  and cached by the browser for offline use.
• Native compilation on desktop with latexmk (TeX Live / MiKTeX / MacTeX), Tectonic or raw engine passes, with a
  persistent build directory per project; shell-escape off by default.
• Optional self-hostable remote compile server (apps/compile-server, protocol v1, Docker image, no dependencies).
• Auto-compile while typing, draft mode, log parsing into linked errors and warnings.

Editor and PDF

• CodeMirror 6 editor with LaTeX completion (528 commands, 99 environments, 350 math symbols, labels, citations, files
  and packages), snippets, KaTeX math preview on hover, live lint, folding, outline, project-wide search and replace,
  Vim and Emacs keymaps, rich-text decorations and formatting shortcuts.
• pdf.js viewer with flicker-free recompiles, thumbnails, search, zoom presets and two-way SyncTeX.

Collaboration

• Serverless real-time collaboration: Yjs CRDT over WebRTC with Trystero signaling (Nostr, BitTorrent, MQTT relays).
• End-to-end encryption (AES-256-GCM, key only in the invite link's URL fragment), live cursors and presence, chat,
  review comments, follow mode and view-only invites.

AI and MCP

• AI chat agent with project tools (list, read, edit, write, search, compile, diagnostics) and diff review; ask mode,
  ⌘K inline edits, ghost-text completion, "fix compile errors" and "explain selection".
• Providers: OpenAI, Anthropic, Google Gemini, OpenRouter, Groq, DeepSeek, Mistral, xAI and any OpenAI-compatible
  endpoint; local models through Ollama and LM Studio; ChatGPT / Claude / Gemini subscriptions through Codex CLI,
  Claude Code and Gemini CLI on desktop.
• MCP client (Streamable HTTP / SSE, stdio on desktop) and TexIt as an MCP server on desktop (127.0.0.1, bearer token)
  with ready-to-paste configuration for Claude Code, Codex and Cursor.

Plugins

• Typed plugin API (@texit/plugin-api, MIT): commands, panels, status-bar items, snippets, completions, compile
  backends, AI tools, templates and settings; permission prompts, developer mode with hot reload, plugin registry.
• Seven built-in plugins: word count, symbol palette, table generator, BibTeX tools (DOI / arXiv / ISBN), snippets,
  lorem ipsum & date, zen mode.

Projects

• Local-first projects in IndexedDB (web) or folders on disk (desktop), dashboard with thumbnails, tags, stars and
  trash.
• File manager with drag & drop and folder uploads, Overleaf-compatible .zip import/export, image and PDF preview.
• Version history with diffs, named versions and restore.
• 15 templates: article, report, thesis, beamer, poster, CV (pdfLaTeX and XeLaTeX), cover letter, book, homework, lab
  report, IEEE paper, math notes and a Spanish article.

App

• English and Spanish interface, light and dark themes, eight accent colors, command palette, quick open and keyboard
  shortcuts.
• Desktop app (Electron) for macOS (dmg/zip, Apple Silicon + Intel), Windows (installer x64 + ARM64, portable) and
  Linux (AppImage, deb, rpm): folder sync, native TeX, OS-keychain secrets, .tex file associations, native menus and
