Locadex for Next.js App Router
Automate translation for your Next.js app
Translating your Next.js app into French 🇫🇷, Spanish 🇪🇸, Japanese 🇯🇵 or any other language is tedious and time‑consuming.
Locadex is an AI agent built to handle 100% of the internationalisation (i18n) work for you. It takes 5 minutes to install.

Locadex:
- Configures your project to use the gt-next i18n library
- Modifies your React components and strings to support multilingual content
- Translates your app into as many languages as you need
- Continuously internationalises and translates as you push new content
Setup process
Step 1: Sign in to the General Translation Dashboard
Go to your Dashboard and sign in to your account.
Step 2: Connect GitHub
- Navigate to the GitHub integration section in your dashboard
- Click “Connect GitHub” to link your GitHub account
- You’ll be redirected to GitHub to authorise the connection
Step 3: Install the GitHub App
- After connecting GitHub, you’ll be redirected to install the Locadex GitHub app
- Choose which repositories to grant Locadex access to:
- Install on all repositories, or
- Select specific repositories
- Click “Install” to complete the GitHub app installation
Step 4: Link Repository to Project
- Back in your GT dashboard, select the repository you want to internationalise
- This links your repo to your translation settings and target languages
- Only one repository can be linked to a project, but you can create multiple projects, each with a different repository
Step 5: Configure settings
On the configuration screen, set up:
- Target languages: Choose which locales to translate into

Step 6: Complete installation
- Review your configuration settings
- Click “Install” to activate Locadex for your repository
- You’ll be taken to an overview page showing your connected GitHub repository
What happens next
Initial setup
Once you’ve completed the installation:
- Immediate PR creation: Locadex will create a pull request on your main branch
- Full setup: This PR runs the complete Locadex setup command, which:
- Installs the GT libraries
- Configures your project for internationalisation
- Sets up the translation infrastructure
- Review and merge: Review the PR and merge it to complete your i18n setup
Continuous internationalisation
After the initial setup is merged:
- Locadex monitors your main or specified branch for pull requests
- When you push new code with translatable content, wait for Locadex to add its commit to the PR
- Once Locadex has committed to the PR, it’s safe to merge — your new code is internationalised
- Your app remains translated without manual intervention
Monitoring Your Repository


Dashboard status
In the dashboard, you can monitor:
