AI demo video maker

Nook is an AI demo video maker that works from the recording you already have. It splits it into steps, writes a script line for each one, adds a natural voice and captions, blurs private data and gives you a share link, an MP4 and a written guide.

What Nook does

Nook turns an existing screen recording into a narrated product demo video. Upload an MP4, MOV or WebM up to 15 minutes. Nook splits it into steps, writes one script line per step, adds an AI voiceover or tidies your own, times captions to every line, blurs private data and renders a video you can share, embed or download.

There's no recorder to install and no timeline to learn. Record with whatever you already use, QuickTime, the Windows Snipping Tool, OBS, Zoom or a Loom download, and upload the file.

How it works

  1. Record your screen the way you normally would. Click through the product once. Talk if you want to, or stay silent. A recording from any tool works, as long as it's MP4, MOV or WebM and under 15 minutes.
  2. Upload it to Nook. Drop the file into the app. Nothing to install in your browser.
  3. Nook finds the steps. If you talked, Nook uses your narration to decide where one step ends and the next begins. If you were silent, a vision model reads the frames and works out what happened on screen.
  4. Nook writes the script. You get one short, plain line per step. Every line is editable. Cut a step, skip one, or rewrite it in your own words.
  5. Pick the voice. Choose a natural AI voice and a pace, keep your own voice with the ums, silences and dead time cut, or go captions only.
  6. Add your brand. Logo, accent color, intro and outro cards, a background (including a mesh gradient), built-in background music and a clean frame around the screen.
  7. Render and share. Nook renders the video and gives you a share page with chapters, an embed code and an MP4 download. Change anything and re-render.

Most of the work is in steps 3 and 4, which is the part that usually takes an afternoon of editing. Our guide to making a product demo video covers what to show and in what order, and the demo video script guide covers how to word each line.

What you get from one recording

A narrated demo video. Your recording with a script, a voice, captions on every line and the waiting cut out. Captions mean it still works when someone watches on mute in a feed or an inbox.

Private data blurred. Nook scans the screenshots for emails, phone numbers, card numbers and API keys and blurs them in both the video and the guide.

A share page. Chapters for each step, an embed code for your site or docs, and an MP4 to download. Add a password and an expiry date when the video is for one prospect or one investor.

Shorter cuts from the same recording. A Social cut (9:16, up to 30 seconds), a Short (16:9, up to 60 seconds), a Square cut (1:1, up to 60 seconds) and a full-length Vertical cut. There's also an Animated story: each step shown on your brand background, either as the real screen in a browser-style window that zooms toward the click, or as redrawn clean cards, up to 90 seconds. It suits launch posts and social.

A written step-by-step guide. A heading, a short note and a screenshot for each step. Draw boxes and arrows on the screenshots, then export as PDF, Word or Markdown for Notion or Confluence. The guide comes from the same steps as the video, so they match.

Translations. The same video in Spanish, French, Portuguese, Italian, Hindi, Japanese or Chinese, each with a native voice. See translated demo videos.

A video editor still gives you more control. If you need frame-exact cuts, multiple camera angles or motion graphics, a timeline editor is the right tool. Nook is for the common case: a clear walkthrough of a product, done in the time it takes to record it.

Questions

What is an AI demo video maker?

A tool that does the editing work of a demo video for you: writing the narration, adding a voice and captions and cutting dead time. Nook does this from a screen recording you upload, rather than asking you to record inside its own app.

Do I need to install anything?

No. Record with any tool you already have and upload the file in your browser. Nook takes MP4, MOV and WebM up to 15 minutes.

Do I have to talk while I record?

No. If you record in silence, a vision model reads the frames and Nook writes the narration from what happened on screen. If you talk, Nook uses your words to split the steps, and you can keep your voice or replace it.

Can I edit what the AI writes?

Yes. Every script line is editable, and you can cut or skip steps, change the voice and pace, and re-render. Re-renders are included: 10 with a single video, 20 per video on Pro and unlimited on Studio.

Will it blur passwords and customer data?

Nook scans for emails, phone numbers, card numbers and API keys and blurs them in the video and the guide. Other sensitive text, like names in a table, isn't covered, so record in a demo account when you can.

Can I get a vertical or short version for social?

Yes. From the same recording you can render a 30-second 9:16 Social cut, a 60-second Short, a 60-second Square cut, a full-length Vertical cut and an Animated story up to 90 seconds.

Can I use my own brand?

Yes. Add your logo, accent color, intro and outro cards, a background and music on any paid video. On Studio, share pages show your brand instead of Nook's.

How is it priced?

Per video, not per seat. The first video is free, a single video is $9, Pro is $19 a month for 10 and Studio is $49 a month for 30.
