NLP++, the NLP Engine and VisualText went open source in 2018, when Text Analysis International was dissolved. Everything built before that point was Windows-only and shipped as commercial installers. Those products are retired: the installers are no longer distributed and the versions are unsupported.
This page exists so the history stays reachable. The pages listed below are kept online for reference, but they are no longer linked from the navigation or the home page, and they are excluded from search engines.
What to use today
The NLP++ Language Extension for VS Code replaces the VisualText IDE on Windows, macOS and Linux. The engine, the extension and the sample analyzers are all at github.com/VisualText. See Everything New in Version 3 and Every Way to Run an NLP++ Analyzer.
Retired: the Windows VisualText IDE
Three generations of the Windows IDE shipped between the late 1990s and 2019. All three are retired and the installers have been withdrawn.
- VisualText IDE — what the IDE was and did
- VisualText 3 — the last Windows release (Windows 10, MSI installer)
- VisualText 2 — the original downloadable release (Windows 7 and later)
Retired: legacy sample analyzers
These sample analyzers were written for the Windows IDE and need it to build and run. Current sample analyzers are maintained on GitHub and install directly from the VS Code extension.
- Full English Parser (TAIParse) — general English analyzer, part-of-speech tagging and shallow parsing
- Corporate Demo Analyzer — compact demonstration of syntactic, semantic and story-level processing
- Resume Analyzer — 2001 prototype for extracting records from plain-text resumes
Retired: superseded announcements
News posts that announced something that has since been replaced. They are kept so the record stays straight, but each now carries a note pointing at what replaced it.
- Version 1 of VSCode NLP++ Extension Released (2020) — the extension is now on version 3
- Unicode Version for NLP++ and VisualText Now Available (2022) — Unicode is standard throughout NLP++ now
- Video Tutorial: Your First Analyzer (2020) — filmed in the retired Windows IDE
- First Open Source NLP++ Zoom Meeting Set! (2020) — a one-time event; the recording is still in the post
Legacy documentation and sites
- VisualText IDE help — the help system that shipped with the Windows IDE, including the NLP++ function reference
- In-depth tour on the old Text Analysis International site
- textanalysis.com — the original company website
Much of the NLP++ language reference in the old help system still describes the language accurately, but the current documentation is the NLP++ textbook, the GitHub repositories and the tutorial videos.
Historical source archives
The analyzer sources below are the original zip archives from the Windows IDE era. They are plain NLP++ text files, kept for reference, and they need the retired VisualText IDE to build and run — they will not work with the VS Code extension as-is.
- taiparse0_8_1_2.zip — TAIParse, the full English parser (2017)
- corporate.zip — Corporate Demo Analyzer (2017)
- Rez0_3_1.zip — Resume Analyzer (2017)
The Windows installers themselves (VT2.exe, VT3.msi and the separate DLL bundle) are no longer served from this site. They were unsigned Windows binaries from 2017–2019 with no security updates, so they have been withdrawn rather than archived publicly.
