6 reasons to try out Mastermind:

When your phone rings, say “Alexa/Hey Google, Ask Mastermind Who’s Calling?”. To send unwanted calls to voicemail, say “Alexa, Ask Mastermind to Reject Call”.

When you want to send a quick text message, say “Alexa/Hey Google, Ask Mastermind to Send Message”. Then say the full contact name and message and Mastermind will send the message using your carrier phone number no matter which carrier you have or which part of the world you are in.

To make a hands-free phone call, say “Alexa/Hey Google, Ask Mastermind to Make Phone Call”. Then say the contact name and Mastermind will initiate the call from your phone or make a hands-free bluetooth call from a connected bluetooth speaker using your phone.

When your phone dings, say “Alexa/Hey Google, Ask Mastermind What Was That?” to find out what the notification was. Mastermind will read out the email, Facebook update, WhatsApp message, Tweet, Instagram post or any notification instantaneously without you reaching for your phone.

Can’t find your phone? Just say “Alexa/Hey Google, Ask Mastermind to Call My Phone”.

First thing in the morning, say “Alexa/Hey Google, Ask Mastermind to Get My Status Update”. Then listen to your phone’s battery charge status, new text messages, notifications, and upcoming calendar events.

      Hi David,

      It will most likely cost $20 for an entire year of unlimited service. We will release out of beta this summer.

    Will mastermind still continue even though Amazon are adding new calling features etc in near future?

    • Nik Bhattacharya Post authorReply

      Great question. Amazon has their own calling/messaging platform. Mastermind supports SMS text messaging and calling through your phone carrier (regardless of which carrier you use). It does not require others to download the Echo app either.

      We think the Amazon calling/messaging capability is very cool (hopefully they will open their bluetooth capabilities to skill devs so we can call using bluetooth pairing between your phone/Echo). But our belief is that we still have a very strong value proposition to our users who want to control their phones through Alexa.

      Hope that helps!

    Thanks for letting me into the beta! Quick question: when it’s released into the full version, do I immediately lose the ability to use this service until I pay, or does it warn me and give me a week or so?

    • Nik Bhattacharya Post authorReply


      You will definitely get a warning a couple weeks before. We won’t just cut off our free beta users. We may even run promos for the free beta users to give a price discount (we are currently thinking an annual fee in the range of $20 per year).

      Hope that answers your question!

    The “Killer App”
    Well Done on this guys. I paid for the closed beta 5 minutes after using it. The endpoint control was the last piece in the Alexa puzzle.
    Have I lost my mind or did I see an update anouncing a desktop app? Im going on 36 hours no sleep so it could have been a figment of my tired mind. Now I cant seem to remember where I saw it or how to get the app. Help and old tired tech out and let me know please. 🙂

    Great app guys!!
