Translation Mode

Mode	Description
LLM Only	Use AI for all segments
TM First	Use TM matches above threshold, AI for rest
TM + Context	Include TM matches as context for AI

Options

Progress Tracking

During translation:

• Progress bar shows completion
• Per-segment status updates
• Can cancel anytime

Retry Feature

Enable ”🔄 Retry until all segments are translated” to:

• Automatically detect empty translations
• Retry failed segments (up to 5 passes)
• Ensure all segments get translated

Tips

Optimal Batch Size

• 50-100 segments per batch works well
• Very large batches may timeout
• Split by page if needed

Quality vs Speed

• Claude Sonnet 4.6: Good all-round balance of speed and quality
• GPT-5.5 / Claude Opus 4.8: Highest quality, slower and more expensive
• GPT-5.4 Mini / Gemini 3.1 Flash-Lite: Fastest, lower cost

Post-Edit Strategy

After batch translation:

1. Review each segment
2. Fix any obvious errors
3. Confirm with Ctrl+Enter
