A listing of language identification tools. Language identification can mean both identifiying text type (e.g. news vs literature) and language (e.g. English vs Frisian vs Dutch).
Most of these tools require training on a big corpus (see List of resources by language for corpora per language), but many come with some prebuilt language models.
