Codex Translation Editor is a free, open-source desktop workspace for missionary teams, agencies, and mother-tongue translators doing high-stakes work in low-resource languages.^1 It is built around continuous translation: the translator steers while AI accelerates the next decision, rather than batch-translating a book and leaving humans to clean up.^3
The flagship idea is Living Memory. Ordinary translation memory stores prior strings, including the wrong ones, and tends to repeat them. Living Memory learns the team's voice, register, terminology, and corrections from context, so a fix made once shapes later suggestions.^3 The same workspace handles Scripture, subtitles, audio, documents, and other structured texts, with project-aware suggestions, back-translation for meaning checks, multi-stage review, and export of completed work.^2 It runs offline-first as a VSCodium-based app for macOS, Windows, and Linux under the MIT license.^2
Frontier R&D cofounders Ryder Wishart (PhD in Christian Theology; computational work on the Greek New Testament) and Ben Scholtens built Codex after work with Biblica and the ETEN Innovation Lab.^5 Come and See Foundation used it to translate The Chosen across many languages.^7 The same team now offers Aquilla, Codex rebuilt for the web; this desktop editor remains in active development.^1^8
