Turn a docs page into a video
Paste the address of a guide or API reference. Get a narrated walkthrough that explains it the way a colleague would.
For this kind of video
Developer docs are read by people who would often rather watch a two-minute explanation first. Making that video by hand means someone who understands the page has to record themselves reading it. SayScreen does the reading.
It opens the page, works out the structure, and writes a narration that picks out what matters: the call that does the work, the option people miss, the gotcha in the example. You approve the script. Then it records the page, scrolling and zooming to each section as the voice reaches it, with word-timed captions.
The example above was made from the MDN guide to the Screen Capture API with the brief “Walk through the MDN guide and explain how getDisplayMedia works.” Nothing was edited afterwards.
What you get
Explanation, not narration
The script says why a section matters, not just what it says.
Follows the page
The camera moves to each heading, code block and note as it is mentioned.
Any public page
Your own docs, a framework's guide, an API reference, a changelog.
Portrait cut for social
The same brief can produce a vertical video for a short-form post.
Questions
Will it read code out loud?
It describes what the code does rather than reading it character by character, and the camera zooms to the snippet while it does.
Can I steer what it focuses on?
Yes. The brief can name the sections to cover, the audience, and the tone. The script is shown for approval before recording.
Does it work on docs behind a login?
Save the page from your own browser with the free Chrome extension and SayScreen records that copy.
What does it cost?
The app is free. The built-in writer and voice cost nothing. With Claude and ElevenLabs on your own keys, a minute of video is roughly 17 cents.
