What it does
T-LAB combines corpus preprocessing, concordances, co-occurrence analysis and thematic or comparative statistics.
Use T-LAB’s Corpus Builder for several texts or categories, or import a single file for a single-text job. Its T-LAB 10 guide recommends a local working folder and a corpus no larger than 90 Mb; this is guide advice, not a measured engine limit. Import prepares the text through segmentation and the applicable lemmatization or stemming, after which keyword lists, co-occurrence, comparative and thematic tools produce tables and graphs. The 2026 full version is proprietary freeware for Windows, without licence fees or expiry. It must be used under the same Windows username that installed it; Mac use requires Windows running.
