Tools and apps
Lingo4G command line tools invoke high-level Lingo4G functions, such as indexing or starting the REST API server. Lingo4G Explorer is a browser-based app that showcases some of the text processing capabilities of Lingo4G.

The l4g
command line tool is the entry point to all Lingo4G functions,
including:
- indexing and re-indexing your documents,
- learning multidimensional embedding vectors,
- running analysis requests in batch mode,
- starting REST API server,
- project descriptor and index diagnostics.
The l4g
tool is Java-based. See the Requirements

Lingo4G Explorer
Lingo4G Explorer is a set of browser-based apps that demonstrate specific text analysis capabilities of Lingo4G. Currently, the main part of Lingo4G is the JSON Sandbox app, which helps to write, execute, tune and debug Lingo4G analysis requests.
See the REST API quick start tutorial for an introduction to building Lingo4G analysis requests.

Lingo4G Explorer (legacy)
The legacy Explorer app offers a visualization-oriented user interface for selected text analysis operations, such as clustering and 2d mapping of labels and documents. Future versions of the 2.x line of Lingo4G will bring similar functionality to the non-legacy version of Explorer. Until that happens, Lingo4G 2.x ships with both the official and the legacy versions of the Explorer app.
See the Quick start tutorial for a quick overview of the features available in the legacy Lingo4G Explorer.
