The deal: The company is now offering a lifetime subscription for $149 with code STREAM25 through August 31 , and Amazon is offering a deal where you can get a 7-day free trial of CuriosityStream when you sign up for a 30-day free trial of Amazon Prime . Note that known documentaries that CuriosityStream offers — like “That Sugar Film,” “The Silk Road” and “The Trials of Muhammed Ali” — are also available for streaming on other platforms as are many of the platform’s original content and celebrity-narrated docs like “Life on Fire” narrated by Jeremy Irons and “Armstrong” narrated by Harrison Ford.
But a lot of these titles are available elsewhere, so unless you’re a documentary fanatic, you can probably find most of what you want to watch on another streaming platform. And some customers have complained about it being hard to cancel their subscription.
