Ask HN: Validate my startup idea for a personal knowledge store

Hi, i'm thinking about developing a personal knowledge store, where you can simply send a link, text, images, youtube url ... and it will get indexed with additional metadata extracted from the source. Then it'll allow the user to fuzzy search the store including the metadata.

example 1:

you send a link to an article:

- article's title gets indexed

- article's content gets indexed

- article's machine extracted meaning/tags get indexed

example 2:

you send an imdb link to a film:

- film metadata is extracted (author, score ..), indexed

and so on for any kind of knowledge you want to store.

Then you can search and match into everything that it's indexed. Every stored information will have a custom view attached allowing the user to interact with it. (example, set that you have seen a film inserted or add a score.)

Would you pay for something like that? If so how much?
