I cannot get my demo to be below 3 mins.. its looks impossible. So I'll drop my pitch here I built an AI Agent that books appointments directly inside chat apps like WhatsApp, Instagram, Telegram and Facebook Business through natural conversations. I hooked up a few things to make it happen: - WhatsApp Business API - Meta scopes for Instagram - Scopes for Facebook messaging - Google Calendar API - AI Agent (powered by Lovable) All of these work together to help businesses get appointments without lifting a finger, saving time and money in the process. PROBLEM: Usually, appointment-based businesses would use booking websites (pretty common these days) to take bookings, but bookings generally dont start from there. It starts with customers sending messages on WhatsApp or Instagram (or social media generally), like, “Are you free on Saturday?”, and then they wait to be directed.

That normally means someone has to stop what they’re doing, reply to the customer, check the calendar, suggest a time, follow up, create the booking (or send a booking link), send reminders, collect payments, and handle any changes afterwards or, worst, answer repeated questions for the nth time. and Because clients/customers require fast responses, businesses lose hundreds of customers a year because their competitors replied first! So I built PingBase PingBase removes that entire back-and-forth. Instead of sending customers somewhere else to book, PingBase turns the conversation they’re already having into the booking. This is usable fo any time of business for multiple use cases. To test the project: Send a WhatsApp message to the fictional business (Studio 9 - already set up on teh platform) at +447587492916 or message @samuellasisi1st on Instagram. Or give it a spin yourself on Lovable: (maybe create your business) https://pingbase.lovable.app Demo below - 3min video - Some screenshots of the product (+ WhatsApp and IG Conversations) - 10+ Min breakdown of how the product works end-to-end Things to note: Meta-required scopes for this are not available for public use yet as it's not something I can control, so you might not be able to connect your own business Instagram or WhatsApp acounts just yet. but you can try...

Impressive

I built this single-file static landing page for Voltline, a fictional AI-automation company, using only HTML, CSS, and Vanilla JS, zero build tools, zero npm, zero frameworks. The aesthetic is "Bone & Volt": a warm off-white canvas with graphite black and one electric-lime accent (rgb(152, 254, 0)) that pops like a circuit trace under a microscope. The vibe? Precision engineering meets retro-futurism. Monospace slash-prefixed labels, tight geometric-sans headlines, orbiting 3D primitives, and tiny "space / starfield" reveals on hover, it feels like a precision instrument, not generic SaaS.

The user can scroll through sections with subtle scroll-triggered animations, hover over geometric elements to trigger micro-visual feedback, and click the "Contact" button to reveal a minimal contact form. The 3D primitives orbit subtly on the canvas, and their rotation is synced to scroll velocity. I also added a "hover reveal" effect where tiny starfield particles drift into view on hover, a small touch of magic that feels like a digital lab under glass.

The real challenge? Making the 3D primitives rotate in sync with scroll velocity without creating jitter or stutter. I had to manually calculate scroll delta and clamp it to a smooth range, then map it to rotation speed via a simple linear interpolation. I wrote a small JS helper that tracked scroll position and velocity using requestAnimationFrame and performance, then applied that to a .rotate() method on the 3D primitives. It took me three hours of trial and error, but once I got the math right, the motion felt intentional, not robotic.🔥 😊

Great job syncing the 3D primitives' rotation to scroll velocity - pulling off that level of interactivity with just HTML, CSS, and vanilla JS is impressive. The electric-lime accent really makes the retro-futuristic vibe pop.
