I have tried to use very simple tags crowd generating tool Tagcrowd. You can enter information in 3 different modes:
- Enter an URL
- Upload a small file (less than 100 kB plain text)
- Copy-paste text excerpt to a box (if you copytext including images – no problem) .
Then click a button “Visualize” and you get a result. I have tried to enter a Lithuanian, Polish or Russian text. I saw tags crowd of Lithuanian and Polish text but I did not get any result with Russian text.
