Replying to messages from PC is never been an easy task. Though there are apps like Airdroid and Mighty text which serves the purpose but they are limited to SMS messages only and requires pairing and server installations. That’s a whole regular and caught-able setup.  And while at office its always be a judging task for all of us whether to give reply or not esp. to those Whatsapp messages. Pushbullet has solved this for upto some extent by its notification mirroring service, which mirrors whatever notification/messages you receives right on your PC. But replying to those messages isn’t possible till yesterday but not from today. Yes, as the Pushbullet’s “Messaging Extension API” is open to all, the other messaging app developers too join the party. Replying to SMS is free but for Whatsapp, you need to spend few dollars ($1.99) and requires Root.
