🧠 Translation Memory (TM)

• SQLite-based, zero configuration
• Fuzzy matching with configurable threshold
• Project-origin context weighting and match provenance
• Auto-learning from your translations
• Autocomplete suggestions while typing
• Import/export TMX files
• Propagate identical translations across entries

📖 Glossary

• Term management with source → target pairs
• Domain tagging
• Consistency checking across the project
• Import/export CSV, TSV, and TBX
• Approved variants and forbidden terminology
• Real-time term highlighting in editor

🤖 AI & Machine Translation

• Inline MT suggestions — DeepL/OpenAI suggestions appear as you translate
• Batch Machine Translate (Ctrl+Alt+T) — translate all untranslated at once
• AI Review (Ctrl+Shift+A) — quality scoring with heuristic fallback
• Back-translation verification — detect meaning drift
• Heuristic confidence estimates per entry, labelled with method and evidence level
• Supported engines include DeepL, OpenAI, Google, Lingva, MyMemory, Argos Translate and OpenNMT-py. Argos and OpenNMT run locally without API keys; OpenNMT requires a compatible model file and onmt_translate on PATH.

✅ Quality Assurance

• 15+ linting checks:
  • Missing translations
  • Placeholder/format string mismatches (%s, {0}, etc.)
  • HTML/XML tag mismatches
  • Accelerator key mismatches (&)
  • Length ratio warnings
  • Duplicate translations
  • Case mismatches
  • CLDR plural form validation
  • Number localization (thousands separator, currency, dates)
  • Inconsistent translations
  • Trailing whitespace/punctuation
• Spell check — red wavy underlines with suggestions and custom dictionary
• Regex tester — validate format strings
• Layout simulator — pixel width checking for UI text
• Unicode inspector — detect invisible/suspicious characters
• Automatic save-time QA — errors are shown before a catalog is written
• Format profiles — dedicated Qt, Android, subtitle, formal, and informal rules
• Accessibility audit — missing labels and duplicate mnemonic keys
• Project health — explainable score covering coverage, stale text, QA, terminology, and accessibility

📊 Project Dashboard (Ctrl+D)

• Per-language translation progress bars
• Pie chart and bar chart (QPainter-based, no external deps)
• Total string counts and summary stats
• Export statistics as CSV

🔀 Git Integration

• Git Diff (Ctrl+Shift+D) — compare with previous commits
• Detect outdated translations (source changed, translation didn't)
• Stage, commit, branch management from within the editor
• Secret scanning before LinguaEdit stages a file
• File change monitoring with auto-reload

🎬 Video Subtitle Translation

• FFmpeg integration — extract subtitles from video files (.mkv, .mp4, .avi, etc.)
• Auto video preview — opening a .srt/.vtt automatically finds and shows the matching video
• Editable timestamps — time intervals as a dedicated column
• Progress bar during extraction with percentage
• User-friendly dialog when FFmpeg is not installed

🔐 Security

• Cross-platform credential storage:
  • macOS: Keychain
  • Windows: Credential Locker
  • Linux: Secret Service (GNOME Keyring / KWallet)
  • Fallback: AES-encrypted file with master password (PBKDF2, 480k iterations)
• Security status visible in Preferences → Security
• Explicit HTTPS host policy, private-network blocking, redacted errors, and no credential persistence in project files

🛟 Local Recovery & Build Inspection

• Atomic crash-recovery snapshots every 30 seconds with user-only file permissions
• Recovery prompt when a newer unsaved local snapshot exists
• Placeholder-safe pseudolocalization for layout testing, including RTL wrapping
• Translation build inspector explaining BUILD/SKIP, completion, and the strict 20% threshold
• Compiled .qm files remain artifact-only and .ts files remain source-only

🌐 Platform Integration

• Transifex — community translations with daily GitHub Actions sync (18 languages)
• File associations — double-click .po, .ts, .xliff, etc. to open (macOS + Linux)
• macOS .app bundle with proper menu bar name and icon
• Linux .desktop file with MIME type definitions

🎨 Themes & UI

• 5 built-in themes including comprehensive dark mode
• Horizontal/vertical layout toggle — editor on right or below
• Auto-collapsing side panel — hides when empty
• Context-aware toolbar — customizable, with overflow menu
• Colored entry borders — red (untranslated), orange (fuzzy), green (translated)
• Save flash animation — green border flash confirming save
• Fullscreen mode (F11)
• Syntax highlighting for HTML tags, format strings, escape sequences

🧪 Testing

• 125+ tests covering parsers, linter, TM, settings, security, GUI regressions, recovery, terminology, and packaging invariants

🛠️ Advanced Tools

• Macro recording — record and replay translation actions
• Versioned plugin API 1.0 — extend linting, suggestions, and transformations with compatibility checks
• Gamification — achievements and streaks
• Pomodoro timer — built-in focus timer
• TTS — hear translations read aloud
• OCR — extract text from images
• Locale map — visual overview of project languages
• QA profiles — configurable validation rule sets
