Glotter

Localization, edited like a manuscript

Every language,
side by side.

Import your locale files, edit every language for a key in one row, and let AI draft what's missing — the tool you'd reach for instead of Lokalise, Crowdin, or Phrase.

What it is

Glotter is a translation management system for multi-language products — the kind of tool you'd reach for instead of Lokalise, Crowdin, Phrase, or Tolgee. You bring your locale files, edit every language for a key in one place, and lean on AI to draft what's missing. Built to make managing real, growing translation sets feel fast rather than fragile.

Capabilities

What you can do with it

  1. 01

    Multi-project structure

    Organize translations into separate projects, each with its own languages and members.

  2. 02

    Per-language JSON import

    Bring your existing locale files in directly — import each language's JSON and pick up where you left off.

  3. 03

    Side-by-side editing

    See and edit every language for a key in one row. No tab-switching, no lost context.

  4. 04

    AI-assisted translation

    Let AI draft missing translations across languages, then review and refine inline.

  5. 05

    Role-based access control

    Invite collaborators per project with roles that scope what they can see and change.
