The Human Language Compiler is a translator for human language based on programming language technology. Therefore it is compact in size and gives control on quality. It indicates confidence with colours:

- Green: semantic translation, should be correct. But not necessarily the only correct one.
- Yellow: syntactic translation, should be grammatically correct. But can be very strange in its interpretation and choice of words.
- Light red: chunk translation, probably incorrect. Builds the translation from small pieces.
- Dark red: word-by-word translation, almost certainly incorrect. Builds the translation word by word.

The green translations come from a tourist phrasebook, which allows you to translate things like "hello" and "how far is the airport from the hotel". But this part can be easily adapted to other uses, such as technical language.

You can translate both speech and text, as selected in the menu in the upper right corner. Translation works between any pair of the supported languages, which means 110 language pairs at the moment. But different languages are on different levels of development. The following table gives a rough idea of what to expect:

| coverage | quality | speed | speech
--- | --- | --- | --- | ---
Bulgarian |  |  |  | in only
Chinese |  |  |  | diff in/out
Dutch |  |  |  |
English |  |  |  |
Finnish |  |  |  |
French |  |  |  |
German |  |  |  |
Hindi |  |  |  | out only
Italian |  |  |  |
Spanish |  |  |  |
Swedish |  |  |  |

This is new and experimental technology, and we are constantly working on the app. Expect frequent updates and improvements!

When you tap on a translation you get a screen with alternative translations. Tapping on each of the alternatives gives you grammatical information: an inflection table, if it is a single word, and a syntax tree otherwise.

The app also provides an input method which you can use as an alternative keyboard which allows you to do translation from other applications, for instance while you are entering SMS or e-mail. To activate it go to Settings > Language & input.

The Human Languge Compiler works completely off-line, without internet connection, although being on-line may give you better speech input and output. The app is small (around 23 MB for all languages). We do not show ads.
