"Pure magic" was exactly what I was thinking when moments after clicking a bookmarklet on an article at Polygon, a perfect transcription of said article arrived in Castro as a podcast episode surprisingly well narrated by a pleasant sounding female bot. The magician performing this trick is Narro, a new web application from developer Josh Beckman that converts the articles you bookmark via Narro's provided bookmarklet into podcast episodes that are oh-so-conveniently deposited into your own Narro-generated podcast feed that you then subscribe to in your podcast player of choice.
For a just launched service, Narro works quite well. The transcription engine is fast (medium-sized articles take just seconds), and despite being peppered with brief spoken and audio oddities, the more-human-than-scary-robot voiceovers are entirely tolerable to listen to. One possible catch might be lack of podcast player support (Narro only specifically mentions Overcast and Apple Podcasts on its website) but Narro does provide a feed address that should be accepted by any podcast player that allows you to cut and paste feed addresses, which is what worked for me with Castro.
The icing on the cake: Narro is free, though that does limit you to a relatively generous 20 article transcriptions per month. A PRO account can be had for $4 a month which removes the article translation limit, adds the option of plain text translations, and offers the promise of "early access to Narro features (iOS app!)." That last bit, about the app, well that could end up being really interesting if such an app included the share extension that could make using Narro with something like an RSS or news reader service exponentially more useful than just bookmarking from Safari alone. In the meantime, for those with too little time to read, or too much time to listen, Narro, the web.app, works plenty fine right now, and is well worth the trip to www.narro.co to sign up.
