LangDex

Humanitarian & Crisis Response

When crisis hits a region speaking Rohingya, Tigrinya, or Haitian Creole, aid workers need basic vocabulary now—not in two weeks when translators are vetted. LangDex's PanLex foundation provides baseline glossaries for 5,700+ languages, deployable offline before boots hit the ground.

The Challenge

The Day Zero Problem

  • 1Aid teams arrive in regions speaking languages with zero digital resources—no dictionaries, no MT, no apps
  • 2Vetting human translators requires background checks and security clearances: days or weeks in active crisis
  • 3Medical mistranslation kills: 'take with food' vs 'take without food' mistranslated in cholera outbreaks
  • 4Volunteer translation platforms (Translators Without Borders) have no coverage for 3AM requests in rare languages
  • 5Each crisis rebuilds language resources from scratch—no institutional infrastructure persists between emergencies
The Solution

Pre-Positioned Language Infrastructure

LangDex maintains a Crisis Concept Schema: ~500 essential concepts (water, doctor, shelter, danger, diarrhea, safe, contaminated) mapped to vocabulary in 5,700+ languages via PanLex. When crisis hits in any region, download the offline pack for local languages before deployment. Baseline communication capability from Day Zero, refined by human translators as they arrive.

Features

Key Capabilities

Crisis Concept Schema

Curated concept list: medical symptoms, safety terms, basic needs, emergency instructions. Pre-translated into 5,700+ languages.

Offline Language Packs

Compressed bundles per language/region. Load onto tablets before deployment. Works in field conditions with zero connectivity.

Glottolog Dialect Resolution

Beyond national languages: 27K languoids mapped including regional dialects. Reach populations invisible to standard translation tools.

Medical Ontology Alignment

Health terms mapped to SNOMED/ICD codes where available. Reduce ambiguity in life-critical communication.

Visual Concept Fallback

When vocabulary fails, concept IDs persist. Point-and-select interfaces work across language barriers.

Translator Handoff

Baseline glossaries bootstrap human translators. They refine, extend, and verify—not start from zero.
