Interactive Demo & Multilingual Support
“I'm thinking of hosting a pool party after Demo Day. Can I extend my stay a couple more days? That shouldn't be a problem. Let me check availability and extend your stay. Since it's after Demo Day, want me to reserve a restaurant near the pool and make sure extra towels are ready? Yeah, that's great. Can we do a reservation for eight? Absolutely. I'm seeing availability at eight o'clock. I'll book that and arrange extra pool towels as well. Does that work? Perfect! Thanks. All set. I'll text you the confirmations. Have fun at the pool, and good luck at Demo Day. Les serviettes ont été livrées à votre adresse. Merci beaucoup!”

Synthesizable in Remotion · key components of the ai-agent-launch-template template.

GlowingCardReveal

UI cards or elements appear with a soft, vibrant glow around their edges, often accompanied by a slight scale-up or slide-in motion. The glow pulses subtly after appearing.

+ Code construction recipe

Use `interpolate` for opacity and scale, combined with a `spring` for a subtle bounce. Apply an SVG filter for the glow effect (feGaussianBlur, feFlood, feComposite) and animate the filter's intensity or color.

ChatBubbleTypewriter

Text within chat bubbles appears character by character, simulating typing, while the bubble itself slides up from the bottom with a gentle ease-out curve.

+ Code construction recipe

Implement `Sequence` and `AbsoluteFill` for chat bubbles. Use `splitText` utility for character-level animation, interpolating `opacity` and `y` position for each character with a staggered delay. The bubble's `y` position uses a `spring` for the initial slide.

DataFlowTimeline

A horizontal or vertical line animates, revealing data points or progress markers along its path. Elements associated with these points slide in or fade up as the line progresses.

+ Code construction recipe

Draw an SVG path for the timeline. Animate the `stroke-dasharray` and `stroke-dashoffset` properties to create a 'drawing' effect for the line. Use `interpolate` for the opacity and `y` position of data point elements, triggered sequentially based on the timeline's progress.
