SumlyAI is an AI-powered tool that provides busy podcast listeners with free summaries of episodes delivered directly to their inbox. The summaries are generated using the latest AI technology but are also reviewed by humans to ensure high-quality. Users can stay up-to-date with their favorite shows and discover new ones without having to spend hours listening to each episode. The tool offers a 7-day free trial period and a monthly subscription plan, with the option to cancel anytime without penalty. Currently, Sumly summarizes podcasts like "Huberman Lab," "Lex Fridman Podcast," "The Tim Ferriss Show," "The Knowledge Project with Shane Parrish," "The Peter Attia Drive," and "Deep Questions with Cal Newport," and they are actively seeking to add more shows to their library.
