Claude visual explainers

These demos show educators that Claude Opus 5.5 has made it possible to create good-quality visual explainers using code alone to break down complex ideas. The examples given are taken from philosophy, maths and economics. Because every picture, word and timing is written in code, rather than generated by a video or image model, it’s easier to keep the content accurate and consistent, and to change one detail without starting again. Each explainer comes in three forms, so you can choose the one that suits you.

Interactive explainer

Go at your own pace, section by section, and try things with the controls. Opens in your browser, with nothing to install.

Video

Watch from start to finish, or download it to share or add to a course page. The explainer videos have no narration: all the words are on screen.

Text version

Everything in words, in an accessible PDF, for anyone who can’t watch or use the explainer.

Adding narration

Can Claude add narration to a video?

Not convincingly: code can only produce synthesised sounds, not natural-sounding speech. If you ask Claude to include narration, it will use the browser’s built-in text-to-speech tools, which sound flat and robotic. This is a limitation of creating videos with code alone – Mayer’s research suggests that narration is generally more effective than on-screen text alongside animation (Mayer, 2021). If you are willing to invest more time, you can add narration in two ways:

  • Give Claude an existing video you’ve made, along with a transcript that shows the timings of the voiceover, and ask it to create animations for part or all of the video. Claude can edit them into your video for you, or give you a silent clip timed to your narration to edit in yourself. This is what Dr Christopher Blunt (Co-Director, LSE100) did for a video already used on LSE100.
  • Write a script (you can ask Claude for help), then record yourself speaking it, for example using the voice recorder app on your phone or the transcribe function in Microsoft Word. Give Claude the audio file and a transcript which has timings, and ask it to create an animated video that matches the timings of the narration. The video here was made this way.
Made from an audio recording: the narration was recorded first, then Claude animated it to match the transcript. 52 seconds.
