FlowAgenda is designed for them. It began showing activity on GitHub in 2023, developed by Qi Yijiazhen as an open project focused on making event planning less rigid. Instead of complex forms or long setup steps, its main job is to turn simple written descriptions into structured events. FlowAgenda FlowAgenda The way it works is refreshingly direct. Write something like a short sentence describing an event (for instance, "Lunch with Sarah next Tuesday, noon"), and the system extracts dates, times, places, and names using language models. Each detail appears as its own card, which can be reviewed and adjusted before saving. Events can then be exported as .ics files for use in common calendar apps. This suits workshops, meetings, study sessions, or quick planning during busy event days.
