Ask HN: Would you like to find sites you have forgotten about?

Hi HN, On multiple occasions have I had the problem that I once visited a site and now I want to get back to it. I remember the site I was on before visiting this site and I remember a qoute from the site, but not the name or URL. The qoute is to generic to find anything on google so googling didn't help me. So, I thought to myself: I should build a service that would record my browser history, encrypt it before sending & storing it, and allow me (and only me) to search it like I would search google. (I even have some really smart search details I think could help to discover the right site) I know I would use this service, and I want to ask you, dear HN: Would you like to use this service? Should I build it? I intend to make it cost a small fee (like $1/month) to make sure that the user is not the product, and to make it clear for users that's the case.
