They're mediocre at best
I don't have an opinion on collaboration, because collaborating without proper organization is like running away from the problem. With proper organization, collaboration is easy.
This isn't a new field -- there have been people who have now closed shop for longer than they were ever active. It's just the influx of a large number of interested people online that have discovered digital tech that's pushing people to make more of these interfaces. None of these organizational structures are inventive or the end-all -- they all use the same methods to store and organize data, the only difference is how well they reduce the friction required for data entry. There's nothing these systems do that couldn't have been replicated 20, 30 years ago. Really, they hardly ever move past the paper paradigm.
GPT-3 et al are a different thing though, and I reckon when they're good enough to be frictionless, the majority of people will stop taking notes altogether. The popularity of this field is solely based on how long it takes for people at OpenAI and others (Stability) to drive down costs to deliver ~1M words/mo to the average customer.
These will all go the way of the phonebook. There'll be "look how my model tears your markdown notes" contests.
Can't speak to that because I don't understand this use-case, but AFAIK it should be possible to modify an org agenda as long as emacs is running somewhere. It could write the current agenda to a file (in a s3 bucket, for example) with the function org-agenda-write, and the application on a phone could read the agenda and "push" the changes back, and an elisp function could handle modifying the actual agenda.
Wouldn't be surprised if this was already posted on the mailing lists as a POC or something.
A web front-end is overkill -- Emacs users can use any completion framework (ivy, icomplete, vertico) with fdfind / ripgrep to get extremely powerful instantaneous search.
Plus, there's no way any org features other than the baseline few are supported.
> I understand that emacs is a big ask for someone to learn
Developing a PWA for it (basically bikeshedding) is much more painful than learning Emacs. Right now, any vim user can jump into emacs with very little friction -- Doom Emacs comes fully configured with evil-mode ootb, and is easily customizable.
I think the reason for the glut of personal kb apps is the relatively high interest of most "tech" people in these things. Unfortunately, most people bow out of their systems very often -- they either don't handle enough data or they give up on old data (or have it ineffectively categorized).
This app (aka "this week's personal knowledge manager") is the same as every other one out there. There's some trying to use GPT-3, but honestly, I don't want my apps parsed by an internet-slurry model. When (if, really) it gets good enough, one wouldn't need to take notes in the first place.
