[Insight Doc Translator — 1500 chars / Blog / Article]

Stop juggling 4 apps for every multilingual Office file.

The current state of multilingual document workflows is broken:
- DeepL translates well but breaks PowerPoint layouts
- ChatGPT can simplify or summarize but destroys formatting
- Adobe Acrobat handles PDFs but loses terminology consistency
- Each step requires copy-paste, manual cleanup, and verification

Insight Doc Translator is a Windows desktop app that does all of these operations in one place, on the same Office file, with layout fully preserved.

▸ 4 operations on the same file
- Translate: 47 languages × 6 AI engines
- Simplify: rewrite at CEFR A1/A2 / JLPT N4-N5 / HSK 1-2 / TOPIK 1 for non-native readers
- Summarize: half-length while preserving meaning
- Polish: rewrite into formal/polite tone

▸ 6 AI translation engines
DeepL · Google · Microsoft Azure · Anthropic Claude · Google Gemini · OpenAI GPT
Pick the best engine per file or per row. Multi-engine simultaneous translation runs the same source through all engines so you can compare outputs.

▸ Multi-language proficiency awareness
The Simplify preset adapts to your target language standard: CEFR for European, JLPT for Japanese, HSK for Chinese, TOPIK for Korean. Choose the right reading level for your audience.

▸ Format support
PowerPoint (.pptx), PDF, Word (.docx), Excel (.xlsx), plain text. Every format keeps its original layout, fonts, tables, images, and embedded objects.

▸ Professional-grade glossary and translation memory
CSV/Excel import, DeepL Glossary sync, TMX standard. Glossary violation detection acts as automated QA.

▸ BYOK (Bring Your Own Key)
Use your own API keys for any of the 6 engines. Combined free tier ~3M characters/month using each engine's free quota.
