Local Reader
I made an on-device AI TTS extension using the WebGPU implementation of Kokoro TTS, the highest-rated open source TTS according to TTS arena. It runs model inference fully in your browser, so no server costs and it's secure. It was pretty easy to get the TTS working since the hard part (inference in javascript/webAssembly/webGPU) was done for me. I added some quality of life features on top: click to jump to a different paragraph, alt j & k for down and up, speed control, and voices (though the default voice has the highest quality). I made the extension mainly because I noticed…

What it does
Local Reader is the first AI TTS extension which provides high quality AI voices directly in your browser at no cost, unlike existing extensions and e-book readers which paywall high quality voices. Powered by the extremely capable and efficient Kokoro TTS model, Local Reader dynamically converts your webpages into high quality speech completely on-device using WebGPU, and provides dynamic highlighting, scrolling, and speed control features.

Inworld TTS2025 · inworld.ai · ▲318Hey HN, this is Igor, one of the engineers behind Inworld Runtime, which we're releasing today in public preview. We built it to solve the common problem we and our customers had: engineers spend more time on AI ops and plumbing than on actual feature development. This was often due to the challenge of using Python for I/O-bound, high-concurrency workloads and complexity maintaining pipelines with streams that use always-changing ML models. Our solution is a high-performance runtime written in C++ with the core idea of defining AI logic as graphs. For instance, a basic voice-to-voice…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
