LangQuest
LangQuest turns any everyday Android or iOS phone into an offline-first translation workstation. Teams record or type translations by voice, text, or image, work for weeks without a signal, and sync automatically when connectivity returns — no laptop, no generator, no technical training required.
Description
Field translation breaks in predictable ways. Laptops fail in heat and humidity, power is rationed, and the internet disappears for weeks at a time. Most collaborative translation software assumes a desk, a charged machine, and a connection, so the work stalls, or it gets captured on whatever phone is at hand and never makes it into a real project.
LangQuest closes that gap. It is a mobile app built for the device the team already owns and already keeps charged. Translators record short, meaningful chunks of Scripture, stories, songs, oral histories, and teaching material, by voice or by text, in their own language, with images attached where they help. Everything is stored locally first. A team can work offline for months and the app syncs on its own the next time it finds a signal, with no manual export, no file shuffling, and nothing lost.
Translations are released under CC0 into an open, public dataset, freely usable for language preservation, research, and training speech and translation models, so the community's work also becomes the foundation for future tools in their own language.
Built for the conditions, not around them
LangQuest runs on ordinary Android and iOS phones, the most durable and most available computers in most field settings. There is no desktop requirement, no local server to maintain, and no install procedure beyond an app store download. Teams that have been blocked by hardware failure or power constraints can keep working.
Offline-first, not offline-tolerant
Projects, quests, and media live on the device. Recording, editing, voting, and reviewing all work with the radio off. Sync is automatic and incremental when a connection appears, which means an intermittent hotspot or a monthly trip to town is enough to keep a distributed team in step.
Oral-first as well as written
Voice is a first-class input, not an attachment to a text workflow. Communities whose translators work orally can contribute directly instead of routing everything through a literate intermediary, and oral and written contributions live side by side in the same project.
Beyond Scripture
LangQuest is already used for Bible translation and is built to handle more: traditional stories, oral histories, cultural material, and educational content. The same project structure workflow applies, so a community can preserve its own material with simple tooling.
Open by default
The app is MIT-licensed and developed in the open. Validated translations are dedicated to the public domain under CC0 1.0—no attribution required, no data sold, nothing locked behind a vendor, so that communities cannot lose ownership of their work. For low-resource languages, this is the difference between contributing to a silo and building the corpus that future speech recognition, synthesis, and translation models will need.
