Unlimited Audiobooks, Podcasts, and Spoken Word Content
What it does
We've taken most major public domain books and brought them to life with voice AI models, in one application that lets you listen to audiobooks, podcasts, and blogs in audio form. We're even working with authors and publishers to bring their catalogs to life. No limits, no credits, (no music), and tons of features specifically for spoken word audio, like transcripts and karaoke. More features (like notes and AI Q&A) coming soon! Currently only available on iOS.

- IGI generated 70k audiobooks with OpenAI Text-to-Speech2024 · listenly.io · ▲140
Hey HN. I’m Ivan, hacker from Ukraine. For about a year, I was working on Listenly — an app to listen to text content with OpenAI's natural-sounding text-to-speech model. At some moment, I realized that it would be cool to take all the public domain e-books and create audio versions for them. So I did it... kind-of. It would cost an immense amount of money to generate all the audio right away (OpenAI TTS costs approximately $0.84/hour of audio; 11labs, for comparison, is 10 times more expensive). So, I took a more gradual approach. I took all the metadata from the Project Gutenberg…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
