Real-time AI speaking coach
A speaking practice app. The learner talks, an AI coach answers in the target language, and the reply is read aloud. English is live now, and the same engine is built to take other language pairs.

Voted Human. The photo feels warmer and fits a therapist app better than the waveform.
FirstReply — reply first, win the booking
Description
Event venues lose bookings because they reply a day late. By then the client has booked somewhere else. FirstReply answers every inquiry with a priced proposal and a held date in seconds.
The automation
1. An inquiry arrives from the venue page, or staff paste in an email.
2. AI extracts event type, date, guests, budget and requests, each with a confidence level and the exact words it came from.
3. Missing date or guest count? It writes a clarifying reply instead.
4. It matches the smallest free space that fits (or the two nearest free dates when it's booked), prices the right package and holds the date for 5 days.
5. The client gets their own proposal page and books with one tap. The hold becomes a confirmed booking.
6. Unsure details, over-budget totals or Review mode send it to a review queue first. Humans step in only when needed.
7. Views, acceptances and expiring holds update the pipeline and alert the team live. Every step is logged to the second.
The design A full design system first (tokens, type scale, components), built as a clickable prototype, then rebuilt in Base44 from prompts. Client pages are mobile-first; the venue side is desktop-first.

You made the connection. Carddek helps you keep it.
After a speed networking event, I came home with a stack of business cards and a problem: remembering the people, conversations, and promises behind them.
So I built Carddek https://carddek.base44.app with Base44.
Scan a business card, keep the details that matter, and turn “great meeting you” into a meaningful follow-up. An interactive living deck brings your contacts to life, while reminders and personalized drafts help you take the next step.
I designed Carddek around the moments networking tools often miss: where you met, what stood out, what you offered, and what you wanted to do next.
My process started with a real experience, grew into a visual identity inspired by physical cards, and evolved through hands-on testing of scanning, card interactions, and mobile layouts. The accompanying video pairs that story with a look inside the app.
The business card still has a place. Now the conversation has somewhere to continue.

Scan, remember, follow up. Great fix for a real networking problem. Did you build this from a pain you felt yourself after an event?
