AI Facts Video Generator

AI Images is the default here. ShortFast art-directs a photographic scene for every line of your script, which suits facts about things nobody can film: a city in 2050, the inside of a volcano, a lost city that may have existed. A video in it typically costs about 25 credits. Because it looks like photography, showing a real place, event or person in it as if real calls for YouTube's AI disclosure, as explained below.

Documentary stock footage is the cheapest, at about 12 credits a video, and it looks real because it is: licensed clips of real cities, coastlines and landmarks, with nothing to attribute. It suits country facts, where the places exist and have been filmed. It shows the place, not the statistic, so the narration has to carry the number. Mixed, which combines footage and AI images, typically costs about 14 and suits 'did you know' videos that move between real things and things nobody has filmed.

3D Animation draws every scene with animated-movie characters, the look of fun facts for kids: a friendly guide explaining why a rainbow is round. Flat Vector is the clean science-explainer look for how-it-works facts: how a zip works, what's inside the Earth, why sunsets turn red. Each typically costs about 25 credits.

Retro Poster renders each scene as a mid-century screen print, the look of old travel posters, which suits country facts: one landmark per scene, with the names and numbers in the narration. Like 3D Animation and Flat Vector, it is plainly an illustration, not a photograph. About 25 credits.

Those three can also turn each image into a short AI video clip. That raises a typical video to about 464 credits, so keep it for a series' strongest episodes; AI Images, Mixed and documentary footage don't have that option.

"Did you know Japan has 14,125 islands? Its mapping agency counted them on 2022 digital maps, more than double the 6,852 figure from 1987, mostly because the maps got more detailed. Only natural land with a coastline of at least 100 m counts, and islands in lakes don't. AI Images look, curious narrator, end on why 'how many' depends on the rule."

"Three facts about the Canada–US border, counted down out loud: number three, it runs 8,891 km; number two, through forests a 6-metre strip is kept clear along the line so it stays visible; number one, two of its boundary monuments stand just 46 cm apart. Mixed look, upbeat narrator, say each number before its fact."

"Fun facts about rainbows for kids aged 6 to 9: you only see one when the Sun is behind you and raindrops are in front; every rainbow is really a full circle, but the ground hides the lower half; from a mountain or a plane you might see the whole ring. A friendly robot guide, 3D Animation look, cheerful narrator, end on where to stand after the next shower."

Each fits the 400-character limit of the box above. Write the facts and figures into the prompt yourself rather than asking for 'five facts about Japan': then you know what the narrator will say and can name the source in the post text. For a countdown, ask for each number out loud; nothing on screen counts for you.

Many of the most shared facts are myths, and an AI draft can repeat them, because they are everywhere. The Great Wall of China is 'frequently billed as the only man-made object visible from space', as NASA put it in 2005, but it generally isn't visible to the unaided eye from low Earth orbit, and it 'certainly isn't visible from the Moon'; China's own astronaut, Yang Liwei, said he couldn't see it. 'Lightning never strikes the same place twice' is on the US National Weather Service's list of lightning myths: lightning often strikes tall, isolated objects again and again, and the Empire State Building is hit an average of 23 times a year. If a fact sounds like something everyone knows, check it before it carries a video.

Give every fact a source you could link to, and name it in the post text. Prefer numbers with a date, because facts age: 'Iceland has no mosquitoes' was a safe line until October 2025, when the Natural Science Institute of Iceland identified three caught at a farm in Kjós. When good sources disagree, say 'about' or say whose figure it is. Canada has the world's longest coastline either way, but Statistics Canada puts it at 243,042 km and the CIA World Factbook gave 202,080 km. Sources age too: the CIA retired the Factbook in February 2026.

Then choose the structure. A countdown gives three to five facts a few seconds each and lives on its ending: keep the strongest for number one, give every fact a line of why, and have the narrator say each number, because the captions are the only text ShortFast adds. One deep fact spends the whole video on a single fact: what it is, why it's true and how anyone knows. A countdown is quicker to make and easier to repeat; a deep fact is harder to copy, which matters for YouTube's monetisation rules below.

YouTube asks you to disclose AI content that looks realistic and shows a real person doing or saying something they didn't, alters footage of a real event or place, or generates a realistic scene that didn't happen. You answer Yes under 'AI use' when you upload; for videos ShortFast posts for you, the setting is in YouTube Studio. Its examples that need no disclosure include clearly unrealistic content, animation, and using AI for the script or the captions, and it says disclosing alone won't limit a video's audience or its eligibility to earn money. AI Images is photoreal, and YouTube's own examples of content to disclose include 'AI generated extra footage of a real place': when AI Images shows a real place, event or person as if real, answer Yes. A 3D, flat vector or poster scene is plainly not footage.

TikTok requires a label on AI-generated content that contains realistic images, audio or video, and encourages one on anything completely generated or significantly edited by AI. These videos are made with AI from script to voice, which TikTok encourages creators to label, so turn on its AI-generated content setting when you post; TikTok says the setting won't affect distribution. Even with a label, TikTok doesn't allow AI content that shows fake authoritative sources or crisis events, so keep a realistic 'what if' disaster plainly hypothetical.

TikTok's misinformation rules apply to facts too. It doesn't allow misinformation that could cause significant harm, 'no matter the intent of the person posting it', and misinformation that may cause moderate harm, such as false claims about treating the common cold, is ineligible for the For You feed, as are unverified claims about crises and major civic events. Facts about health, public safety, crises and climate are the ones these rules name. Its list of what's allowed includes 'documentary or educational content reporting on or condemning misinformation', which is where a myth-busting video belongs.

Labels and monetisation are separate questions. YouTube's monetisation policies say generic or repetitive content 'includes content that looks like it's made with a template, or that may feel repetitive to viewers after watching several videos in a row from the same channel', and templated list videos are the classic case. Its examples of what can't earn include 'image slideshows, templated storylines, or scrolling text with minimal or no narrative, commentary, or educational value' and 'AI-generated content made with generic or unoriginal templates giving the impression of mass production without adding the creator's original, authentic insights or perspective'. A script read off a trivia site matches a reused-content example too: 'content that exclusively features readings of other materials you did not originally create, like text from websites or news feeds'. What YouTube asks is that 'the substance of each video should be materially varied and deliver creative, educational, or other value'; for facts, that's the explanation and the source.

If your channel's fun facts are made for kids, YouTube also judges them against its quality principles for kids and family content. One is 'deceptively educational' content, which 'might promise to teach something, like colors or numbers, but show incorrect or unhelpful information', and a video found to break the principles may see limited or no ad earnings.

It doesn't fact-check. ShortFast writes a fluent script, and fluent isn't the same as true: a draft can repeat a popular myth or an out-of-date number. Check every fact before you render. In an automated series each episode brings a new fact and there is no approval step, so choose email delivery and check each one before it posts.

AI images can get maps, flags and lettering wrong: a flag with the wrong pattern, a coastline that doesn't exist, a sign in garbled text. Put names and numbers in the narration, which the captions show word by word, rather than relying on the picture, and swap any scene that shows them wrong for another image or one you upload. It doesn't animate maps either; for a border or a route, describe it in the narration or upload a map you have the right to use.

The narration is fixed once rendered. Spot a wrong number after the render and you can fix the caption, but the narrator still says it: correcting the words means generating again. In a series, the next two episodes are queued: you can edit their scenes, captions and post text, re-time or delete one, but not change its script.

There are no on-screen counters or list graphics: no countdown number in the corner, no quiz timer or answer card. The only text ShortFast adds is the burned-in captions of what the narrator says, in one of 9 caption styles and 18 fonts, so a countdown's numbers have to be spoken.

None of these channels use ShortFast; they show what facts audiences reward. WatchMojo ('Thousands of Lists') is the countdown at scale, with titles such as 'Top 10 Dumbest Historical Blunders of All Time'. RealLifeLore ('Answers to questions that you've never asked') builds most videos on a 'why' question about a country or a place, such as 'Why 600,000 People Live On This Rock With No Resources'. Half as Interesting gives a single odd fact or question a whole video, as in 'This Is The Shortest Train in the United States', in a tone its tagline sums up: 'Education-y explainer videos that are almost good enough to watch'. Kurzgesagt – In a Nutshell and MinuteEarth make animated science explainers, often around one question, such as 'How Are Memories Stored Inside Your Brain?' and 'Why Are Some Sunsets SO MUCH Better Than Others?', and both publish their sources: Kurzgesagt links 'Sources & further reading' under its videos, and MinuteEarth lists references in the description.

What they share is one question or one ranking per video, and a reason to believe the answer. That is the part to copy; the visuals are the part ShortFast handles.
