PickyCal-style Event Filter Calendar

Filter any event source with expressions and subscribe only what you actually care about

Problem

People often want just a handful of cross-source events, like Starship launches, the next James Bond cinema release, or the Classic Tetris World Championship finals, but calendar apps dump whole schedules on them. Sources are fragmented, so you forget to add one.

Solution

Let users add event sources (ICS links, public JSON, light web scraping), write filters with &, |, ! and parentheses, then regularly fetch and publish matching events as a personal ICS/CalDAV feed that refreshes automatically.

Users

Calendar power users who track specific launches, releases, movies, and niche events, plus operators or assistants who need niche feeds in work calendars.

MVP

Three source types (ICS URL, JSON API, simple CSS selector); boolean filter editor; one subscribable ICS link; scheduled polling with dedupe; failure alert email.

Revenue

Free for 2 sources; $4/month or $40/year for unlimited sources, faster refresh, and CalDAV; enterprise SSO tier.

Why now

Public event APIs and ICS feeds are exploding, but calendar vendors have no incentive to build generic filtering. A single dev with a scraper and expression engine can cover the long tail.
