Frequently Asked Questions
Can I use Undermind instead of LTP for Chinese text?
No. Undermind searches and synthesizes scientific papers; it does not perform Chinese word segmentation, tagging, or parsing. If you need linguistic annotations on Chinese text, LTP is the tool.
Does LTP help with literature review?
No. LTP is a Chinese NLP library, not a search or synthesis tool. Literature review is Undermind's domain.
Is either tool free for commercial use?
Undermind is freemium, with deeper full-text analysis behind its Pro plan. LTP is free open-source, but commercial use requires a negotiated license obtained by email — there is no self-serve commercial option.
How do I access each tool?
Undermind is used inside Claude and ChatGPT. LTP installs via pip install ltp and can also be run through its DLL interface or ltp_server web service.
Which is faster to deploy?
LTP installs with one pip command if you have Python. Undermind requires no setup — you interact through your AI assistant — but production searches average about 2.9 minutes, so it is not built for instant answers.
