Inspiration

I was inspired by my own frustration managing RSVPs for community and AI events. I thought it would be kind of cool to have an AI voice agent call to confirm the attendees. This led me to build this app as something fun to engage event participants with.

What it does

It is a lightweight web application that helps event managers turn unreliable "registrations" into firm, data-rich RSVPs using AI voice calling technology. The AI Agent calls the registrations and confirms attendance and other details.

How we built it

I built the project using Bolt.new for the web app scaffolding and backend workflows, Twilio for outbound phone calls, and ElevenLabs for realistic AI voice synthesis. The workflow is simple: I upload attendee lists and event context, trigger a campaign of AI-powered calls, and collect responses in real time. All data streams to a live dashboard, with a downloadable CSV for easy handoff to vendors or staff.

Challenges we ran into

Doing everything myself meant wearing a lot of hats—product designer, developer, and tester all at once while also managing my busy day job. One of the biggest challenges was tuning the AI agent’s script so that it sounded genuinely helpful rather than robotic. I had to iterate repeatedly on voice prompts and question flows to avoid sounding like spam. Ensuring reliable Twilio call delivery, managing live data streaming, and handling privacy around contact data and call recordings also took significant effort.
