# Indus Script — Interactive Demo

Six tools for exploring the undeciphered Indus Valley Script (2600–1900 BCE).

## Tabs

| Sign Lookup | Enter T604 or 604 — see glyph, role, frequency |
| Validate Sequence | Enter any sequence — get BERT/N-gram/ELECTRA scores |
| Predict Masked Sign | Enter T638 [MASK] T420 — model predicts the missing sign |
| Generate Sequence | One click — generates a new grammatically valid inscription |
| Sign Explorer | Browse all 641 signs filtered by role (PREFIX/SUFFIX/CORE/RARE) |
| Sign ↔ Number | Convert between T604 and 604 |

## Models used

- TinyBERT (classifier + MLM)
- N-gram RTL
