I like to keep daily logs such as:
- Met with person X; discussed organizing some social event.
- This is an interesting post on making Pitch Decks <link>
- Finished chapter 3 of thesis.
But each line belongs to a separate category/timeline:
Right now what I'm doing is keeping separate timelines (in the form of google docs for each category) but I would like to have everything in one place, where I can sort/search through them by tags/importance/date/etc or a boolean combination, with all the capabilities of google docs.
Is there a cross-platform tool I can use for this? I am not asking for a diary (there are plenty, but mostly aimed at teenage girls!). I want something more technical.
