I’ve had the chance to work with Ventali and the Sudo team — they’re incredibly competent at what they do. At Macaron AI, billing and monetization are at the core of building sustainable consumer AI apps. We spend a lot of time thinking about this problem ourselves, and a product like Sudo (one API for all models, plus billing + monetization features) would be a huge unlock. We’ll definitely be...

Great product! Can I post our job positions on the platform as a startup founder? Upvoted

This is really practical and useful!

This is really cool! I am wondering if it can one day integrate backend tasks!

Well, Kimi is also launching today lol. A lot of pressure to keeping going, fast.

This is such a fun and interesting product! I've actually created my version of him before, using system prompt. But obviously, you guys are doing a much more serious job. Upvoted!

This looks helpful and interesting! Eager to try the product.

Absolutely love the vibe here — clean, focused, and full of personality. Feels like the kind of tool that actually respects your time and your taste. Beautiful work, upvoted!

Absolutely adorable and unexpectedly soothing! 🐾 I love the customizable animations and how it reacts when you interact with it. Great for boosting your mood during busy work sessions!

Impressive reasoning capabilities, but the recent controversies are concerning. xAI’s Grok 3 indeed delivers on its promise of advanced “think” mode — with cutting‑edge reasoning, standout performance on math/science benchmarks like AIME 2025 and GPQA, and impressive code generation potential. I also value its DeepSearch for real-time insights and extended context handling.

The interface looks so spicy haha! Really like it. Upvoted :)

I've always been wanting a voice notebook like this. Thank you for building such a product! Upvoted.

Beautifully crafted! 21st.dev feels like an AI-powered npm for UI components—slick, intuitive, and a joy to remix.

Clueso is exceptional—finally a tool that goes far beyond Google's Flow. The intuitive, frictionless experience makes navigating complex tasks feel effortless. Loving the thoughtful touches and how it genuinely simplifies workflows. Highly recommend!
