Create a whiteboard animation videoWhiteboard videos look like a teacher's best sketch: black marker lines on a clean white surface, with a touch of red and blue to point at what matters. Arrows, simple figures, coins, graphs and small icons do the explaining. The look tells viewers they are about to learn something before a word is spoken, which is why trainers, educators and finance explainers have leaned on it for so long.
ShortFast builds a whiteboard video from a topic or a script you paste. It writes or keeps the narration, picks a voice, splits the lesson into scenes and draws a new marker sketch for each step, all in the same pen style on white. Captions are burned in. One thing to know: each scene is a finished drawing rather than a hand tracing the lines in real time, so fast cuts do the job the drawing hand used to do.
Start from an idea such as "How compound interest actually works", or paste a script you already wrote and ShortFast keeps your words.
Every scene gets its own picture, and a shared palette, setting and recurring characters keep each image in the Whiteboard look from the first scene to the last.
Pick one of 21 narration voices. Captions are burned in, and the Whiteboard defaults (fast cuts, no music, hard cuts) are already set. You can change any of them.
Download the video, auto-post it to TikTok, YouTube Shorts and Instagram Reels, or turn the theme into an automated series that makes a new episode on a schedule.
A whiteboard frame has almost nothing in it. There is no scenery, lighting or texture competing for attention, so whatever is drawn is the only thing to look at. That makes the style unusually good at showing structure: a process running left to right, a cause pointing to an effect, a small pile of coins growing into a large one. Viewers read the diagram and hear the explanation at the same time.
The red and blue accents matter more than they seem to. In a frame that is otherwise black on white, one red circle or blue arrow tells the eye exactly where to go. It is the visual equivalent of a teacher tapping the board, and it keeps a busy concept readable on a phone screen.
The style also carries authority without feeling stiff. It reads as a lesson, not an advertisement, which helps with money and self-help topics where viewers are wary of being sold to and quick to scroll past anything that looks like a pitch.
Whiteboard works best when the script teaches a concept with parts: how compound interest actually works, the psychology of habits in three steps, how a startup goes from idea to IPO, how a loan is priced. Anything you would explain by drawing on a napkin fits. Numbered frameworks and step-by-step processes are its strongest format.
Self-help and productivity content works when the script turns the idea into a mechanism, such as a trigger, a routine and a reward drawn as a loop. Pure encouragement with no structure works less well, because there is nothing for the marker to draw beyond a smiling face.
It is a weak choice for narrative. A dramatic story, a mystery or a character arc wants mood, color and faces, and a sketch on white cannot build tension. It is also wrong for anything visual in itself, like travel, food or fashion. If your topic is a story with people in it, the stick figure or cartoon explainer styles will carry it further.
The style defaults to fast pace, no music and no transitions. A new sketch every two to four seconds replaces the drawing hand of traditional whiteboard animation: instead of watching one diagram build slowly, the viewer sees each step arrive as its own frame. With no music bed the explanation stays clear, and a hard cut feels like turning to a fresh page of the board.
Script it the way you would teach it. Start with the payoff ("Saving $100 a month adds up faster than you think, and it is not luck"), give each step its own sentence so it gets its own sketch, then restate the rule at the end so it sticks. Keep the words in the captions: AI images are unreliable at writing text, so let the drawings carry the ideas and the captions carry the numbers.
For a longer lesson, pick 2 to 3 minutes and switch the pace to normal so each diagram holds for about five seconds. The Animate images option can turn each sketch into a short clip in the same marker style for videos up to 2 minutes. It adds movement to the scene and costs more credits, billed per second of video.
Give ShortFast one theme and it makes a new whiteboard animation video on a schedule, every day, twice a day or a few times a week. Each episode covers a new topic on the theme, and the video is emailed to you or posted to your accounts. Themes that work well in this style:
A playbook for running a faceless finance channel: personal finance, investing and money explainers built from stock footage and narration. Formats, hooks, a sample script, RPM ranges and the monetization path.
Open NicheA playbook for a faceless health channel: fitness, sleep and nutrition explainers that stay inside accepted guidance, with formats, hooks, a sample script and realistic earning ranges.
Open NicheA playbook for a faceless motivation channel: discipline, mindset and stoic-style narration over real footage. Formats, hooks, a full sample script, RPM ranges and how to stay original at daily volume.
