April (YC S25)

Voice AI Assistant to handle emails & calendar hands free

August 14, 2025 One weekend hackathon → quit what I was doing → building April full-time (YC S25)

A few months ago, I joined a hackathon with no big plan - just the goal of building something I actually wanted for myself and getting free pizza.

At the time, my mornings were chaos: 50+ unread emails, calendar conflicts, and me wasting an hour before I could start “real” work. I always kept thinking, what if I could just talk to my inbox and calendar while driving to work instead of clicking through them?

In that 12-hour hackathon sprint, my friend and I hacked together a rough prototype: a voice assistant that read my emails out loud while I drove, let me say “reply to Sarah” or “delete all promos,” and even rescheduled meetings without touching my screen. It wasn’t pretty, but it worked - and for the first time in years, I hit Inbox Zero before my day began.

That weekend project became April. Today it clears my inbox and organizes my calendar during my commute or a quiet walk. We’re now building it full-time (YC S25), adding features like screen preview and PDF reading, and bringing it to more people who feel buried in email.

If you’ve ever scratched your own itch at a hackathon and had it turn into something bigger - I’d love to hear your story.

    Can it filter out all the spam emails and find my important ones alone ?

      Hey yes, it finds the important emails you need to address and reads them out to you!

    Really impressive.....solving your own pain point and scaling it into a yc startup is no small feat. what’s been harder so far... building the tech or getting users to adopt it?

      We've built the tech - now time to get users to adopt it :)

I used to waste 1 hour everyday clearing 50 emails before I could even start work. So I built a voice assistant to get me to Inbox 0 and manage my calendar schedule using just my voice! My own AI executive assistant !
