What it does

Dia TTS is a 1.6B parameter open-source text-to-speech model by Nari Labs. It generates ultra-realistic, emotionally expressive speech, including non-verbal cues like laughter and sighs. Ideal for creators, developers, and researchers.

Create, transform, and clean production-ready audio in one AI workspace — voice generation, cloning, covers, stem separation, denoising, sound effects, and more.

Generate or clone voices, create sound effects and song covers, separate stems, reduce noise, and transcribe audio—all online, with no software to install. From multi-speaker dialogue to natural conversation and expressive delivery, click any sample to play. Type a script or sound prompt, or upload a recording, song, or reference voice. Pick the focused workflow for generating, transforming, separating, or cleaning your audio. Listen to the result, adjust the input or settings, and create the version that fits your project. Download ready-to-use files and keep every result organized in My Creations. Purchase Dia TTS credits for AI voice generation, music, and audio tools. Everything you…from dia-tts.com

    Kitten TTS is an open-source series of tiny and expressive text-to-speech models for on-device applications. We are excited to launch a preview of our smallest model, which is less than 25 MB. This model has 15M parameters. This release supports English text-to-speech applications in eight voices: four male and four female. The model is quantized to int8 + fp16, and it uses onnx for runtime. The model is designed to run literally anywhere eg. raspberry pi, low-end smartphones, wearables, browsers etc. No GPU required! We're releasing this to give early users a sense of the latency and voices…

  • Tapflow 2.0▲1,125

    We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
