Subtitle editing

Install

The latest release is v1.8.19. Download the file for your system:

The Python package published on PyPI may lag behind the GitHub release. For v1.8.19, download the wheel above, then run:

python -m pip install ./linguaedit-1.8.19-py3-none-any.whl
linguaedit-gui

The macOS app requires macOS 13 or newer. The Windows installer does not require a separate Python installation. The Debian package requires Python 3.10 or newer and installs its Python dependencies during setup.

Optional tools: ffmpeg for extracting subtitles from video, hunspell for spell checking, and git for version control features.

Supported formats

LinguaEdit edits the following localization formats:

TMX is supported for translation-memory import and export. It is not an editable catalog format. See Supported Formats for details.

Features

• Edit several files in tabs; open files by drag and drop.
• Find and replace text with regular expressions, case matching, or whole-word matching.
• Filter entries by translation status, warnings, bookmarks, and tags.
• Use translation memory with fuzzy matches, context weighting, and TMX import/export.
• Maintain glossaries with approved and forbidden terms, and check term consistency.
• Get suggestions from DeepL, OpenAI, Google, Lingva, MyMemory, Argos Translate, and OpenNMT-py. Hosted services may require API credentials. Argos and OpenNMT can run locally; OpenNMT also requires a compatible model and onmt_translate on PATH.
• Check placeholders, markup, plural forms, terminology, accessibility, and other translation issues before saving.
• Review changes with Git, monitor files for external edits, and recover unsaved work from local snapshots.
• Translate subtitle files and extract subtitles from video with FFmpeg.
• Use the dashboard, layout simulator, regex tester, OCR, text-to-speech, macros, and configurable QA profiles.

Translations

The project has 18 language catalogs with 1,612 messages. Catalog updates sync daily from Transifex through GitHub Actions. Release builds include catalogs that are more than 20% translated.

To contribute a translation, join the project on Transifex.

Build from source

git clone https://github.com/yeager/linguaedit.git
cd linguaedit
python3 -m venv .venv
source .venv/bin/activate
python -m pip install -e ".[dev]" build
linguaedit-gui

Build a wheel with:

python -m build --wheel

The build compiles .ts catalogs to .qm files inside the package when a catalog is more than 20% translated. Compiled .qm files are build artifacts and are not stored in the source tree. The release workflow builds the macOS apps, Windows installer, Debian package, and Python wheel; see GitHub Actions.

The automated suite contains 147 tests. To run it locally:

QT_QPA_PLATFORM=offscreen pytest -q
