I’ve been working on markwhen as a way to easily create timelines just from text.
I’ve used it personally to help plan and coordinate my own wedding (https://markwhen.com/rob/wedding) and for keeping track of life events, and I’ve seen it used for event planning, project management, and to visualize historical events or periods of time.
I personally like tools that let you immediately start using them, and I set out to do that here with markwhen.
Let me know if you have any questions!
