Ask HN: Building an app to make real-world conversations searchable. Want it?

We’re working on Retrospect (http://goretro.co), an app that sits in the background and intelligently records location and audio from your day-to-day interaction with the world. It lets you access your real-world conversations just like you might search your email. Look for things like “conversations with Sarah at Starbucks” or “Baseball games I’ve gone to with my Dad”, then play back the recorded moment.

We’re launching sign-ups for our free beta starting today if you’d like to try it out.

What do you think? Would you use something like this?
