    Before you click a link, hover over it and read where it really goes. If the button says your bank but the address says something else, delete the email.

The first five scenes are the 62-second phishing-awareness sample, made from one page of notes. The last three come from a slide deck turned into a video with its own pages.

About five minutes, start to finish

What it does

Five looks, one click

Whiteboard, chalkboard, blueprint, notebook paper or kraft. Try them on scene 4.

Scene 4 in the whiteboard look

Follows your deck

One scene per slide, in order, built on your speaker notes. Or one video that covers the whole document.

Shows your real pages

Use a PDF's own pages as the visuals. Each one appears line by line while the narrator explains it.

Captions on every scene

Big, readable captions timed to the voice, so the video works with the sound off.

Ready to post

A standard MP4 with the right length in the file, so Instagram and WhatsApp play all of it.

Questions people ask

Is it really free?

Yes. There are no credits, no watermark and no sign-up. The skill runs on your own Claude account, so each video uses your plan's normal usage, the same as any other chat.

What do I need?

A Claude account on any plan, with code execution turned on in Settings. On Team and Enterprise plans an owner may need to allow skills first. Install it once on the web or desktop app, then use it anywhere you use Claude.

Is my document kept private?

Your file stays inside your own Claude session. The skill sends nothing to us or anyone else. The only downloads are its tools from the Python package index and, in the lite version, the voice file once. You can open the ZIP and read every line before installing.

Which files can I use?

PDF (including scanned pages), PowerPoint .pptx, Word .docx, Markdown, plain text, or just a description of the video you want. For old .ppt or .doc files, save them in the newer format or as PDF first.

Can it use my own slide designs?

With a PDF, yes: ask Claude to use your pages and each one is revealed line by line in the video. With PowerPoint, save the deck as PDF first, then attach that.

Which languages work?

Claude can write the script and captions in your language, including Yoruba, Igbo, Hausa, French and many more. The built-in voice speaks English, so videos in other languages come with captions and no narration for now.

How long can a video be?

Up to 60 slides or pages. Most videos run one to three minutes and take a few minutes to make.

Can I change it after it's made?

Just ask in the same chat: "make scene 3 shorter", "switch to the chalkboard look", "make it vertical for Reels". Scenes you didn't change are reused, so small edits come back fast.
