Check source strings for translation problems and project how long each will be in other languages

Localisation readinessFreeFor writers, developers and product teams

25/day

free runs a day, no sign-in.

Before: what you give it

The example input, as typed in. You paste text, CSS, markup or notes.

strings:
  save = Save
  cart.items = You have {count} item(s) in your cart [max 30]
  date = Delivery on March 3rd
  welcome = Welcome back, {name}! Last seen {0} {1}
  frag = to the left of
languages: de, fr, ja
expansion: de=1.35, fr=1.25, ja=0.55

After: what comes back

The first lines of a real run on that input. Nothing here is edited by hand.

5 strings. Expansion source: your table. Languages: de, fr, ja.
Projected length = current length x language factor. Strings of 10 characters or fewer get 1.6x the growth, up to 20 get 1.3x, up to 40 get 1.15x, because short UI words expand most.
4 strings with findings; 1 clean.

cart.items: "You have {count} item(s) in your cart" (30 chars, worst case 43 in de)
  - "(s)" plural: many languages have more than two plural forms; use a plural rule (ICU or gettext)
  - a number followed by a counted noun with no plural rule: 1 vs many (and few, many, other in some languages) will break
  - over the 30 character limit in: de, fr (worst de: 43)

date: "Delivery on March 3rd" (21 chars, worst case 30 in de)
  - hard-coded month or weekday name; format dates with the locale
  - English ordinal suffix (1st, 2nd); ordinals differ by language

welcome: "Welcome back, {name}! Last seen {0} {1}" (27 chars, worst case 38 in de)

What you get

Projected lengths per language, overflow against limits, and findings on fragments, plurals and placeholders

What it cannot do

Uses your growth factors or our rough planning table, named in the output; projections are not measured translations.

Who it is for

The form starts with the same example input, so you can run it first and then swap in your own.
