Cal.build

I developed Cal.build because I found it annoying to deal with planning documents shared as PDFs, especially when they came from people outside my usual work circle.
I wanted a simple way to go from an idea to a schedule to a working calendar.

You enter what you want to plan, and it generates a calendar with a .ics URL that you can subscribe to (Google Calendar and others).

For example: “Plan a 5-day team summit in Costa Rica starting May 1st, including team building activities and project planning sessions.”

This returns a complete schedule with editable events, a public URL, and live updates.

Features: 1. Converts text to calendar entries. 2. Provides a subscribable .ics link. 3. Enables sharing and automatic updates.

Stack: Next.js, Supabase, AI SDK, deployed on Vercel.

Feedback is welcome.
