Introducing Nook (2026): Turn Recordings Into Demo Videos

Nook takes a screen recording you already have and turns it into a narrated demo video, a written step-by-step guide and a share page you can send to anyone. You upload the file, Nook splits it into steps, writes a short script line for each one, voices it, adds captions and builds the guide. You check the result, change what you want, and share it.

This post covers why we built it, what you get from one recording, how it works, who it is for, what it costs, and what it does not do yet.

#Short answer

Nook is a web tool that turns a screen recording you already have into a narrated demo video with captions, a step-by-step guide with screenshots, and a share page. It writes the script, voices it or tidies up your own voice, and blurs private data. The first video is free, then $9 per video.

• What it is: a tool that edits screen recordings into demo videos and guides. It does not record. You bring an MP4, MOV or WebM file up to 15 minutes long.
• What you get: a narrated video with captions, a step-by-step guide with screenshots, a share page with chapters, extra cuts for social and launches, and translations into seven more languages.
• Voice options: a natural AI voiceover, your own voice with the ums and silences cut out, or captions only.
• Privacy: Nook scans the screenshots for emails, phone numbers, card numbers and API keys and blurs them in the video and the guide.
• Pricing: your first video is free (up to 1 minute, small watermark). After that it is $9 for one video, or $19 a month for 10 videos on Pro. There is no per-seat pricing.
• What it doesn't do yet: record your screen, give you a timeline editor, or handle recordings longer than 15 minutes.

You can make your first video free and see the result before you pay anything.

#Why Nook exists

Most people who need a demo video do not need a video tool. They need one good demo this week.

Maybe you are launching on Product Hunt on Tuesday. Maybe Shopify wants a screencast before they approve your app. Maybe a client needs a handover video showing how to update their own site, or a customer keeps asking how to export a report and you are tired of typing the same answer. In each case the job is the same: show someone how a thing works, clearly, in a few minutes.

The usual options do not fit that job well.

A full video editor gives you a timeline, tracks, keyframes and a learning curve. It is built for people who edit video every day. If you make a demo twice a quarter, you relearn the tool every time, and a three-minute demo can take an afternoon of cutting dead time, lining up voiceover and typing captions.

A subscription demo tool is built for teams that produce demos continuously. That is a good fit for some people, and we say so in our comparisons. But if you need one video for a launch, paying monthly per seat for a product you will open three times is a strange trade.

So what happens instead is that the recording gets made and never gets finished. It sits in your Downloads folder as Screen Recording 2026-10-14 at 11.42.07.mov. It is eight minutes long, it has two false starts, a notification pops up in the middle, and you meant to edit it "later." Then the launch happens without it, or you send the raw file and apologize for the length.

Nook is for that file. You already did the hard part, which is knowing your product and clicking through it. Nook does the part in between: finding the steps, writing what to say, cutting the waiting, adding captions and turning it into something you are comfortable sending.

#What you get from one recording

One upload produces a set of things you can use in different places. You do not have to use all of them.

#A narrated demo video

The main output is a video where each step has one clear script line, voiced and captioned. Dead time between steps is removed. You can add your logo, an accent color, intro and outro cards, a background (including a mesh gradient), built-in background music and a clean frame around the screen. You can download it as an MP4 or share it by link.

Captions are on every line, so the video works on mute. That matters more than it sounds: a lot of demo videos are watched in a feed, a Slack thread or an open-plan office with the sound off.

#A step-by-step guide

Alongside the video, Nook writes a guide: a heading, a short note and a screenshot for each step. You can draw boxes and arrows on the screenshots to point at the thing that matters. The guide exports as PDF, Word or Markdown, and the Markdown pastes cleanly into Notion or Confluence.

Some people would rather read than watch. Some need to search the steps later. Some need to print a checklist for a new hire. The guide covers those cases from the same recording, without a second round of screenshots. If you want the manual version of this process, our post on turning a screen recording into a step-by-step guide walks through it.

#A share page

Every video gets a share page with chapters, so viewers can jump to the step they care about. You get embed code for your help center or docs, an MP4 download, and optional password protection and an expiry date for links you do not want floating around forever.

#Cuts for other places

The same recording can produce several shorter or reshaped versions:

The Animated story is the one we spent the most time on. Each step appears on your brand background. You can show it either as the real screen inside a browser-style window that zooms toward the click, or as redrawn clean cards that summarize the step. It is meant for launch posts and social, where a full walkthrough is too slow and a raw screen is too busy.

#Translations

Nook can translate the script and captions into Spanish, French, Portuguese, Italian, Hindi, Japanese and Chinese, each with a native voice. With English, that is eight languages from one recording. You do not re-record anything. If you sell to customers outside English-speaking markets, see our page on translated demo videos.

#How it works, step by step

Here is what actually happens between upload and share.

1. Record with whatever you already use. QuickTime, the Windows Snipping Tool, OBS, a Zoom recording or a Loom download all work. The file can be MP4, MOV or WebM, up to 15 minutes. You can talk while you record or stay silent.
2. Upload the file to Nook. There is no extension to install and no recorder to learn.
3. Nook finds the steps. If you narrated, Nook uses your speech to work out where each step starts and ends. If you recorded silently, a vision model reads the frames, including the text on screen, and splits the recording based on what changes.
4. Nook writes one script line per step. Each line is short and says what is happening and why it matters. This is the part most people find hardest to do by hand. Our guide on writing a demo video script explains the principles we built this around.
5. You review and edit. Every line is editable. You can rewrite a sentence, cut a step, skip one, change the pace or pick a different voice. Nothing is locked in.
6. Nook renders the video and the guide. The video gets the voiceover, captions, your branding and the privacy blur. The guide gets its headings, notes and screenshots.
7. You share or download. Send the share link, paste the embed code, download the MP4, or export the guide as PDF, Word or Markdown. Make extra cuts or translations whenever you need them.

If something is off, change the line or the step and re-render. Re-renders are included in every paid option, with limits that depend on the plan.

#Why there is no timeline editor

People sometimes ask where the timeline is. There isn't one, by design. The point of Nook is that you edit words and steps, not frames and tracks. If you change a line, the timing follows. If you cut a step, the video closes the gap. For the job Nook is built for, that is faster and much harder to get wrong. If you need frame-level control, a traditional editor like Descript or Camtasia is the better tool, and we say so plainly in our roundup of AI demo video tools.

#Who it is for

Nook is for anyone who needs to show how software works and does not want to become a video editor to do it. A few cases come up again and again.

#Launches

A launch needs a short, clear video for the listing, a vertical clip for social and maybe a longer walkthrough for the website. One recording covers all three with the regular video, the Social cut and the Animated story. See our page on Product Hunt demo videos and our guide to making a product demo video.

#App reviews

Marketplaces and platforms often ask for a screencast before they approve an app. Nook has presets and checklists for Shopify, Meta, Google OAuth verification and HubSpot, and it writes the test steps reviewers want in text form too. If you are preparing a submission, read app review demo video requirements and our Shopify app review screencast guide, or go to app review videos.

#Client handovers

Agencies and freelancers finish a project and need to show the client how to run it themselves: how to add a product, update a page, publish a post. A video plus a printable guide means fewer "quick questions" after the invoice. Our post on client handover videos has more.

#Help center articles

Support teams answer the same questions every week. A short video with the written steps underneath, embedded in the help article, answers the question where people are already looking. See help center videos.

#SOPs and internal training

Standard operating procedures are often a screen recording nobody watches or a document nobody updates. Nook gives you both from one recording, and the guide exports to Word or Markdown for your wiki. See SOP videos.

#Sales follow-ups

After a call, a short video showing exactly the workflow the prospect asked about is more useful than a generic deck. Record it once, let Nook tidy it up, and send the share link. See sales demo videos.

#Voice options

There are three ways to handle the audio, and you can switch between them before you render.

• AI voiceover. Nook voices the script with a natural AI voice. You pick the voice and set the pace. This is the most common choice for silent recordings and for anyone who does not like hearing their own voice.
• Keep your own voice. If you narrated while recording, Nook can keep your audio. It cuts the ums, the silences and the dead time, and it times the captions to your actual words. This works well for founders and support people whose own voice is part of the point.
• Captions only. No voice at all, just captions on every step. Useful for feeds, for places where sound is unwelcome, or when you plan to add your own music.

To be clear about one thing: the AI voice is not your voice. Nook does not clone voices. If you want to sound like yourself, keep your own audio.

#Privacy blur

Screen recordings leak things. A customer's email in a table, a phone number in a profile, an API key on a settings page, a card number on a billing screen. Even when you prepare demo data carefully, something slips through.

Nook scans the screenshots for emails, phone numbers, card numbers and API keys and blurs them, in both the video and the guide. It is a safety net, not a guarantee, so it is still worth watching the final video before you send it. The best protection remains a demo account with fictional data, which we cover in our demo video best practices.

#Pricing, and why it is per video

If you buy one video for $9 and then decide to upgrade within 7 days, the $9 comes off.

We price per video because that is how most people need demos. You need one for a launch, one for an app review, one for a client. Paying for a seat every month, whether you make a video or not, does not match that. With Nook you can pay once for the one video you need, and if you start making them regularly, Pro brings the cost per video down a lot. There is no per-seat pricing on any plan, so a whole team can share an account without the bill growing with headcount. We wrote more about this choice in why we price per video.

#What Nook doesn't do yet

Nook is new and made by a very small team. Here is where it falls short today, so you can decide before you upload.

• It does not record. You need a recording first. Any recorder works, but Nook is an editor, not a capture tool.
• No timeline editor. You edit script lines and steps. You cannot drag clips on a timeline or set keyframes. That is intentional, but it means Nook is the wrong tool if you want frame-level control.
• 15 minutes maximum. Longer recordings need to be split before you upload. In practice, shorter videos are better anyway, but it is a hard limit.
• Step detection can misjudge some recordings. On silent recordings, the vision model works from what changes on screen. Very fast clicking, or apps that are mostly visual with little text, can lead to steps that are merged or split in the wrong place. You can edit the steps, but you may need to.
• Browser chrome shows as is. If your tabs, bookmarks bar or extensions are visible in the recording, they will be visible in the video. Clean up the browser before you record.
• The AI voice is not your voice. If that matters, keep your own audio.
• It is a new product. There will be rough edges. If you hit one, tell us and we will fix it.

#What's next

The biggest thing coming is a Chrome extension recorder. It records in the browser and captures the exact clicks as they happen, so Nook does not have to infer them from the frames. That should make step detection more accurate on fast or visual recordings and make zooming toward each click more precise. It is built but not in the Chrome Web Store yet. We will announce it when it is.

Beyond that, we are watching which cuts people use, where step detection struggles, and which app review presets are missing. If you have a recording that Nook handles badly, that is exactly the feedback we want.

If you want to know how it is put together, we wrote up how we built Nook on Cloudflare. If you are comparing tools, see Trupeer vs Nook.

#FAQ

#Do I need to install anything to use Nook?

No. Nook works in the browser. You upload a recording made with any tool, such as QuickTime, Windows Snipping Tool, OBS, Zoom or a Loom download. A Chrome extension recorder is coming, but you do not need it.

#What file types and lengths does Nook accept?

MP4, MOV and WebM files up to 15 minutes. The free video is limited to 1 minute. Paid videos can use the full 15 minutes.

#Can Nook work with a recording where I didn't talk?

Yes. If the recording is silent, a vision model reads the frames, including the text on screen, to find the steps and write the script. You can then pick an AI voice or use captions only.

#Can I edit what the voiceover says?

Yes. Every script line is editable. You can also cut or skip steps, change the voice and pace, and re-render. Each plan includes re-renders: 10 for a single video, 20 per video on Pro and unlimited on Studio.

#Does Nook clone my voice?

No. You can choose a natural AI voice, keep your own recorded voice with the ums and silences removed, or use captions only. The AI voice does not sound like you.

#How does the privacy blur work?

Nook scans the screenshots for emails, phone numbers, card numbers and API keys and blurs them in both the video and the guide. It is a safety net, so review the final video before sharing, and use fictional demo data where you can.

#How much does Nook cost?

Your first video is free (up to 1 minute, with a small watermark). One video costs $9 for up to 15 minutes. Pro is $19 a month for 10 videos, and Studio is $49 a month for 30 videos with your own branding on share pages. There is no per-seat pricing.

#Which languages can Nook translate into?

Spanish, French, Portuguese, Italian, Hindi, Japanese and Chinese, each with a native voice. A single $9 video includes 2 translations, and Pro and Studio include all 7.

#Try it on the recording you already have

If there is a screen recording sitting in your Downloads folder that you meant to edit, that is the best place to start. Upload it, read the script Nook writes, change what you want, and see whether the video and guide are something you would send. The first one costs nothing, and you will know within a few minutes whether Nook fits how you work. Make your first video free.
