In plain words

This tool is a voice-based AI investor character built for practicing startup pitches. It uses GPT-4o trained on investor notes to simulate realistic pitch feedback through voice conversations. The system combines multiple services—Vapi for orchestration, ElevenLabs for voice synthesis, Vercel for hosting, and Supabase for data storage. It's designed for entrepreneurs who want to refine their pitch delivery and responses in an interactive, conversational format before pitching to real investors.

    Luke from ElevenLabs here. We just released Scribe Realtime v2, our new real-time Speech to Text model. We rebuilt it from the ground up around a new architecture that uses predictive transcription – it anticipates the next likely word before it’s spoken. That makes it both fast (around 150 ms latency) and highly accurate. Scribe v2 Realtime outperforms every low latency transcription model across 30 commonly used EU and Asian languages – 93.5% accuracy, compared to Gemini 2.5 Flash (91.4%), GPT-4o MiniTranscribe (90.7%), and Deepgram Nova 3 (85%). It supports 90+ languages including…

    Made using Google’s Lyria music model — an image → music translator. I’m a designer at Google, doing a self-initiated 30 days with Gemini experiment. This is technically a promo, but honestly just pleased with how this one turned out. I don’t write code — this was entirely vibecoded.

    Hi HN — I’m Viggy, founder of MyClone. We originally built a marketplace connecting startup advisors with founders. After ~6 months, we had hundreds of recorded discovery calls and transcripts. We noticed something interesting: The first 10 minutes of most advisory calls were almost identical. • What do you do? • Who is this for? • Pricing? • What information do you need from me? • Am I a good fit? So we pivoted. Today, MyClone lets service professionals (consultants, CPAs, etc.) deploy an AI voice agent that: • Answers FAQs in their voice • Runs structured intake conversations • Qualifies…

    I was at FB/Meta from late 2013 to early 2023, mostly working in the compiler/runtime spaces. I got hit in the spring 2023 layoff wave. I immediately started making games in my newfound free time (a lifelong interest, and I even worked in AA(A?) back ca. ~2000), and in October 2023 I stumbled upon the idea of a roguelike pachinko/plinko game inspired by Luck Be A Landlord. Things snowballed quickly, I started talking to publishers, then worked like crazy through all of 2024, almost the hardest I've ever worked in my career, and launched the game in December 2024. It's sold…
