Amazon has announced the results of a recent Alexa Skills Challenge, run on Devpost, with the theme "Tech for Good". Even if you didn't compete it is instructive to see the projects that were selected as winners.


In the challenge, which ran from July 24 to September 17, Amazon invited developers to build Alexa skills that would have a positive impact on the environment, local communities, and the world. As well as the cash prizes itemized below there were 500 Participation Prizes - Echo Dots as for participants in the US or a prize of equivalent value for those outside the US and US participants aged 13-17.

At the outset Amazon specified what it was looking for in Tech for Good skill submissions: 

  • They solve a customer problem. For example, helping customers gain access to information faster or leverage public data and resources. By allowing customers to access more information via voice, they are able to complete tasks more efficiently.
  • They inspire customers to learn and take action. For example, influencing customers to adapt and learn over time. By giving customers actionable tasks, using your skill is more likely to become a daily habit.
  • They deliver a seamless user experience via voice.  Being simple to use and understand. If your skill is too complex, you risk losing the customer’s attention and they will be less likely to use your skill again. 

Specific judging criteria were: 

  • Quality of the Idea (15 points)
    Including creativity and originality, and the potential positive impact of the Skill.
  • Technical Implementation of the Idea (15 points)
    Including how well the idea was executed by the developer, the complexity of the services used to build the skill, the depth of integrations with data or third-party APIs, whether it performs as expected, and more.
  • Potential for Engagement (25 points)
    Including the extent to which the Skill is widely useful, engages user over multiple turns (dialogues), might be extended to other scenarios, and more.
  • Quality of User Experience  (25 points)
    Including how natural the experience is to the user.
  • Habit-forming ability (20 points)
    Including how likely the Skill could change a customer’s daily habits, impact their day-to-day use, and potentially become habit-forming over time.
  • Customer Engagement (Round 2 only) (10 points)
    Including a variety of factors such as the type and duration of usage, the number of new and recurring customers, customer ratings, and more.

Ten finalists won $5,000 each plus promotion of their skill and twelve cash prizes were awarded. as follows - the links are to the Alexa skill on
