CLUSTER CALENDAR-LANGUAGE-NATURAL · 14 ENTRIES · EARLIEST ENTRY 2013-10-30
Natural-language calendar event parsers
This cluster comprises calendar apps and utilities that convert natural-language text, voice, images, or files into structured calendar events, often extracting details like date, time, and location. The dated entries appear sporadically from 2012 to 2026, with a long hiatus between 2013 and 2022, followed by a couple of entries in late 2025 and early 2026, so the timeline shows sparse and irregular activity rather than a clear trend. Traction is led by seminar-calendar with one star, while orbit-scheduler and Fantastical Calendar have zero stars.
Entry timeline
ENTRY TIMELINE
Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
