I built Cal.build after getting frustrated with planning documents shared as PDFs usually from people outside my daily workflow.

I wanted a minimal way to go from idea -> schedule -> live calendar.

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

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

Returns a full schedule with editable events, a public URL, and live updates.

Features: 1. Text-to-calendar conversion 2. Subscribable .ics link 3. Shareable and auto-updating

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

Would appreciate feedback.
