I can't use Named Entity recognition for this tool, how can I get for free?
Welcome to Prodigy forum @Shafieabdi!
Prodigy is a paid software and we don't really offer free versions.
For one time payment of $390 you get an unlimited lifetime license that let's you download and install Prodigy on your machine.
We do offer free time-limited research licenses for students for academics. You can apply for one by emailing contact@explosion.ai.
