  • Where there’s a screen there’s a way
    This was a long time ago, so I used Ivona voices and the program TextAloud (though I admit I pirated them because they were/are expensive). Looking into it Ivona was bought by Amazon and replaced by Amazon Polly which looks like it will fulfill your needs pretty well! Source: almost 1 year ago
  • Level Up Your Blog With Writer Analytics and Text-to-Speech
    I was inspired by a post from Ran Isenberg last week. He created an automation to take his blog posts, run them through Amazon Polly, and create a spoken form of his content.

This is great for consumers who are in the car or have accessibility needs. - Source: dev.to / about 1 year ago

We are considering offering our developers the option to either write technical content through a Community Content Program for us for a $200 fee, or to donate that amount to charity.

  • How we use analytics as a privacy focused OSS company
    TLDR: Privacy is really important for us at Unleash. Here you will find the full story on how we ended up with an analytics solution that does not collect personal data and has very short retention. Whenever we evaluate a new feature at Unleash, we always start with one question. How does this fit with our values? This question is powerful. It can quickly qualify or disqualify a feature from consideration, putting... - Source: dev.to / almost 2 years ago
