Overview

Harf Labs set out to revolutionize podcast discovery and consumption with the creation of Casti. Recognizing the overwhelming nature of the modern podcast landscape and the difficulty users face in finding relevant, high-quality content, we conceived and developed Casti as an in-house solution powered by artificial intelligence. Our goal was to build an app that not only curates personalized podcast clips but also provides intelligent summaries, full transcripts, and seamless discovery across topics of interest. Casti represents Harf Labs' commitment to leveraging AI technology to create user-centric applications that transform how people consume and engage with audio content.

The Challenge: Information Overload in the Podcast Ecosystem

While the podcast industry continues to grow exponentially, users face significant challenges in discovering content that truly matches their interests and time constraints. Key pain points include endless scrolling through irrelevant episodes, difficulty finding specific topics or discussions, lack of time to consume full-length episodes, and the absence of intelligent curation that adapts to individual preferences. There was a clear need for a podcast discovery platform that leverages AI to understand user interests, curate relevant content, and present it in digestible, personalized formats. Harf Labs recognized this challenge as an opportunity to innovate and create a superior solution that transforms podcast consumption from a time-consuming search into an effortless, personalized experience.
