Questions and answers.

No. There is no registration and no password. Enter your email address and we send you a sign-in link (a "magic link"). It works once and expires after 15 minutes. Your account is created the first time you sign in.

Yes. Fill in the order form, then enter your email address. We email you a link to confirm your order. Opening it signs you in, creating your account if you do not have one, and adds the order to it. Nothing is charged, and nothing appears in any account, until you open that link. If you do not confirm the order, we delete the form and any paper you uploaded after 7 days.

Yes. In your account, under Security, choose Set up two-factor sign-in and scan the QR code with an authenticator app such as Google Authenticator, Microsoft Authenticator, 1Password or Authy. After that, signing in needs the link we email you and a 6-digit code from the app, so someone who got into your email still could not sign in.

When you turn it on we show you 10 recovery codes, once. Keep them somewhere safe: each one signs you in once if you lose your phone. If you lose both, email [email protected] from your account's address and we will check your identity before removing two-factor sign-in. A team's owners can require it for everyone in the team.

It depends on what the video shows from the paper. You choose one of two kinds when you order.

A redrawn video copies no text or images from the paper. It relays the paper's ideas and findings in our own words, with every diagram redrawn and every chart plotted from the numbers the paper reports. Copyright protects how a paper is written and drawn, not its ideas or facts, so a redrawn video does not normally need the publisher's permission. We can make one from a paper under any licence, including CC BY-ND and CC BY-NC. You still confirm that you may share the paper with us, because you upload it for us to read.

A video that shows the paper, with clips of its pages and figures beside the animation, reproduces the paper, so it needs the right to adapt it. That is the case if you or your organisation hold the copyright, if your publishing agreement allows adaptations, if the publisher has given permission, or if the paper is under an open licence that allows adaptations and commercial use: the public domain, CC BY, or CC BY-SA, whose share-alike terms then apply to the video. Most authors assign copyright to their publisher, so being the author is not always enough: check your publishing agreement. We cannot accept CC BY-ND or CC BY-NC for this kind of video, because those licences do not allow adaptations or commercial use. If your situation is something else, tell us when you order and we will check it before we start.

You can prepare the order now. Mark it as confidential or embargoed when you upload, with the embargo date. Nothing from a flagged paper is published or used as a sample, it is sent to a language model only on terms that keep no copy and train on nothing, and everyone on our team who handles it sees the flag. You decide when to publish the finished video.

Those terms are not in place yet, so we cannot yet process confidential or embargoed papers: you can save the order, and we keep it and email you when we can. The privacy policy has the details.

Yes. Give us a web address and we'll explain it on video. Choose a single page, or a whole website: we then read its home page and up to 10 more pages from the same site, choosing the ones that say most about what you do. It costs the same as a video of a paper.

We read only public pages, as a visitor would. Our reader names itself as ExplainAPaperBot and follows the site's robots.txt. It never tries to get round a login, a paywall or a check for automated visitors: if a site stops it, we ask you to upload the page as a PDF instead, and carry on from that. A video of a website is always redrawn, in our own words and drawings, and never shows the site itself. You confirm that you own the website, or are authorised to act for its owner.

You can also give us a website to take your brand from. It can be the same site as the one the video explains, or a different one.

A PDF of up to 25 MB that is not password-protected. Please remove any data that could identify research participants before uploading.

It is used to make your video and nothing else, and deleted 90 days after you accept the video. The privacy policy has the details.

Our specialised AI agents draft the script from your paper and send it to you to read, edit and approve. With human review, one of our editors checks it first. Then it is yours to edit: you have full control of the narration, and you can say what you want to see at each point in the video. Nothing is made until you approve it.

No. AI video models paint every frame from patterns they have learned, so they can show garbled text, a wrong number or a chart that is not in the paper. Our specialised AI agents draft the script, and then our own software draws every frame in code: words are typeset, charts are plotted from the paper's own numbers and diagrams are drawn to show what the script says. Read more: How we keep a video true to the paper.

An optional add-on. One of our editors checks it against the paper and signs it off before it comes to you for approval. If the script is revised, it is reviewed again.

It costs £99 per video (£118.80 inc. VAT), and can be added any time before you approve the script. Enterprise teams can instead switch on the review add-on, so that every video submitted while the add-on is active gets human review. Human review is not included in the base enterprise plan.

Human review is a process, a second person's check, not a guarantee. Your approval of the script is always the final check.

A revision round is one complete render of your video. Each video includes 3, and the first render uses one. Your own script edits are free; asking us to rework the script uses a round. An extra round is £19 (£22.80 inc. VAT).

The round for a render is used when you approve the script and it goes into production. Asking for changes to a finished video does not use a round itself: the new render does, once. Fixing a video that does not match the script you approved, or that contains our mistake, never uses a round.

We send reminders. A finished video you have not responded to is treated as accepted after 14 days, and a video left waiting on you for 90 days is closed. The terms explain both; neither affects your statutory rights.

We will confirm timing when we send your script. Your dashboard always shows whether a video is with us or waiting for you, and we take on only as many videos as we can deliver.

A narrated video with captions, a transcript and a poster image. Once paid for, you can use, publish and share the video anywhere, permanently, including commercially, and the script is yours.

You choose a target length when you order: 1, 2, 3 or 5 minutes. It is also the most the video will run, and your script is kept within it. Any length up to 5 minutes for the price of a one-minute video: every length uses one video credit. We may charge for longer videos in future. We'll tell you before we do, and it won't affect videos you've already ordered.

Need a longer video, such as 30 or 60 minutes, or one covering several papers, such as a research archive? Contact us and we will talk it through with you.

Yes. On the order form, choose a widescreen video, Shorts or both. Shorts are a set of 3 vertical videos made from the same paper, for YouTube Shorts, TikTok and Instagram Reels. Each opens on a hook, says one thing in plain language and has its subtitles on screen, and each says only what the script you approved says.

Shorts are included at no extra charge. We may charge for them in future. We'll tell you before we do, and it won't affect videos you've already ordered.

An interactive lesson page made from your video, with a teaching pack to download. The lesson page shows the video in parts, with a short explanation of each part and questions after it that give feedback on every answer. It also has a glossary, three activities with safety notes, and a note for teachers: what the paper did and did not claim, misconceptions to watch for, and curriculum links where they are honest. The pack has teacher notes, a worksheet, an answer key and glossary cards as PDFs, your video's slides with the questions added, the video itself and its captions. It is £4.99, plus VAT, for one video, and included on the enterprise subscription.

Our specialised AI agents draft the lesson from the script you approved and the claims we checked against the paper. A second, separate AI review checks every answer and note against the paper, and every answer must cite a checked claim. You then review and approve the lesson. Until you do, only your account can see it.

The lesson page is private until you turn on its share link. Pupils need no account. The page sets no cookies, uses no analytics, stores nothing on the device and loads nothing from other websites: answers stay on the page and are gone when it is closed.

Yes. The order form lets you hear each narration voice before you choose, and pick a layout: slides (text beside the animation), full animation, a mix of the two, or your own. For your own layout, download our PowerPoint or PNG template, move the coloured boxes to where the title, the text, the animation and, optionally, your logo should go, export the slide as a PNG and upload it. We show you what we found, and our team checks it before your video is made.

Style options are included at no extra charge, and voices are always free. We may charge for some style options in future. We'll tell you before we do, and it won't affect videos you've already ordered.

Yes, free on every order. On the order form, give us your website address and we read your colours, fonts and logos from it, or upload your logo and we suggest colours from it. We show you what we found in a preview of a title card and a caption, and you can change any of it: your main and accent colours, text and background, fonts and which logo to use. We warn you if text would be hard to read, and suggest a fix.

We use open fonts that can be embedded in video. If your own font is not one of them, we choose the closest open font and say so; if you hold a licence to use your font in video, you can upload it instead. You confirm that you are entitled to use the logos and brand assets, and we use them only to make your videos. Your brand is saved with your account for your next video.

On the enterprise plan we also build a full brand pack by hand, within 10 working days of receiving complete assets.

The finished video is yours. Download it from your video's page, with its captions, transcript and poster image, and use it or upload it wherever you like: your website, YouTube, LinkedIn, social media, news pages or an intranet. We keep it in your account for a set time (see the next question), and we never publish it anywhere unless you ask us to.

If you would rather not upload it yourself, we can upload it to YouTube or another platform for you. Ask us.

From 1 November 2026, a video bought on its own or in a pack is kept for 3 months after delivery. We then delete it for good, with its stills, slides, lesson pack and source paper. We email you a month and a week before, so you can download your copy, which is yours to keep. Stills, slides and lesson packs can be added only while we still hold the video.

Videos ordered before 1 November 2026, or ordered later with credits bought before that date, are not affected: we keep them until you delete them or close your account.

To keep your videos for longer, start a storage plan from your account (£4.99/month, plus VAT). It keeps all your videos while you pay for it, and you can cancel it at any time in one step.

On the enterprise subscription, your team's videos are kept while you subscribe. If the subscription ends on or after 1 November 2026, you keep full access for a month; then the videos are archived, and we delete them 12 months after the subscription ended. An owner can restore access for 30 days (£99, plus VAT), or re-subscribe to get everything back at no extra cost. The terms have the details.

Yes, once it is finished. Open the video's page and choose Delete this video. It goes to the recycle bin on your account page, where you can restore it for 30 days. After 30 days, or sooner if its storage period ends first (see the question above), we delete it permanently: the video, its captions, poster, transcript, stills, slides and lesson pack, and the paper you uploaded.

Deleting a video does not refund the credit or any add-ons you bought for it. It still counts in the totals on our numbers page and in your account's footprint total.

On a team account, the person who ordered a video and the team's owners can delete it or restore it. Only an owner can delete a video permanently before its 30 days are up. We keep a record of who deleted or restored each video and when, and the billing records the law requires, but nothing from the paper or the script.

12 months from purchase. The enterprise monthly allowance does not roll over.

If you buy as a consumer, you can cancel within 14 days of purchase. Unspent credits and unused add-ons are refunded in full. For a video already under way, the refund depends on how far it has got: in full before we send the first script, half once the script is sent, and nothing once the video is delivered. The terms set this out in full.

Yes. Send us an enquiry, for organisations or for universities, and we will set up your team and invoice you on 30-day terms.

Prices are shown without VAT, with the VAT-inclusive figure below each one. VAT is worked out for your location at checkout.

Every video comes with captions and a full transcript, so it works with the sound off and with a screen reader. Text and diagrams are drawn in code, so they stay sharp and legible.

Not yet. Captions and the transcript come in the language of the narration, which today is English. Captions in other languages, and narration in other languages, are on our roadmap.

We build it to WCAG 2.2 AA. If anything gets in your way, tell us and we will fix it.
