knwl.js

What do you like best?

I like best that it's lightweight and free, and works well for extracting information such as dates (separated as year, month, day), times, links, phone numbers, emails and places in real time in the browser. It's available also for Node.js if you need server side processing.

What do you dislike?

I would like support for the italian language out-of-the-box, but I understand parsing strings in many languages is a difficult and specialised task so I need to create my custom plugin.

Recommendations to others considering the product:

If you want to avoid sending a lot of asynchronous data to your server and wish to do part of the work of extraction client-side, Knwl.js is the right tool for the job.

What problems are you solving with the product? What benefits have you realized?

Web apps nowadays need to do a lot of things automagically and whatever can be done client-side without security risks is welcome. If you want to intercept valuable data from what a user writes in your app's text fields (to propose suggestions, etc.), Knwl.js is a very good and solid choice.
