    Visit CuriosityStream.com

    ~24s
    Open your browser and go to curiositystream.com. Click the option to start a free trial or subscribe. Enter your email address and create a password. You'll be asked to choose a plan — monthly or annual. Annual is the better deal if you plan to watch regularly.

    Quick Tip

    Quick Tip: Check if CuriosityStream offers a bundle with Nebula at checkout. The combined price is often only a few dollars more and doubles the content available to you.

    ~16s

    Browse by topic or search for something specific

    ~17s
    The main menu has categories like Science, History, Nature, Technology, Society, and Kids. Tap a category to browse titles. If you have a specific subject in mind — dinosaurs, World War II, black holes, the ocean — use the search bar to find relevant documentaries directly.

    Start watching and build your queue

    ~16s
    Tap any title to see its description, runtime, and rating. Press Play to begin. To save something for later, use the bookmark or watchlist button on the title's page. Your saved items will appear in a dedicated section so you can find them quickly.

    Adjust video quality and subtitles

    ~24s
    While watching, tap the screen to bring up playback controls. Look for the settings gear icon to adjust video quality (useful if your internet connection is slower) and to turn on or off subtitles. CuriosityStream offers subtitles in multiple languages for most titles.

    Quick Tip

    Quick Tip: If a video buffers (pauses to load) often, lower the video quality setting to SD or 720p. This uses less internet data and plays more smoothly on slower connections.

    CuriosityStream is a streaming service dedicated entirely to documentary films and series. It was founded by John Hendricks, the same person who created the Discovery Channel. And it shows — the content focuses on science, history, nature, technology, society, and space exploration.

    If you love watching documentaries about how the world works, the history of civilizations, wildlife in remote corners of the earth, or the latest breakthroughs in medicine and technology, CuriosityStream offers thousands of titles to explore. Many are original productions made exclusively for the service.

    The price is one of the best deals in streaming — plans start at around $3.99 per month, and the annual plan drops that further. There is also a free trial available. For documentary lovers, this is exceptional value compared to hunting through different platforms for individual titles.

    CuriosityStream works on smart TVs, Roku, Amazon Fire Stick, Apple TV, iPhone, Android, and any web browser. The app is well-organized and easy to navigate.

    One feature worth knowing about: CuriosityStream partners with another service called Nebula, a platform created by educational YouTube creators. Some bundle offers include access to both CuriosityStream and Nebula together at a discounted rate. If you enjoy thoughtful video essays and educational content from YouTube channels, this bundle is worth considering.

    The browse experience is excellent. You can filter by topic, length, difficulty level, and whether a title is suitable for kids or adults. The library includes both short films under 20 minutes and full feature-length documentaries.
