Objective
One sentence the opening scene can say aloud. "Students can name the three inputs of photosynthesis" is a scene. "Cover chapter 4" is not.
For teachers and course creators.
Explainimate is built for a lesson plan to video: paste the objectives or the step outline for one class, review the storyboard, and export a short chalkboard walkthrough. The form opens at 3 minutes in Chalkboard Color, with a drawing hand. Switch to Whiteboard if you would rather teach on a white board.

This prepared science lesson plays in your browser, drawn by the same pen that will draw yours, in the style selected above. It is a sample of the drawing, not a video of your plan. Press play, or pick another style to redraw it.
Start from the plan you would teach, not from a blank timeline. The box is there to turn a lesson plan into a spoken walkthrough. Leave it on Topic so the plan is rewritten as narration you can edit. Choose My script only when the text is already the narration you want read. Import text takes .txt and .md files up to 400 KB. A PDF, a slide file or a photo of the board is skipped; copy the words out first.
Paste the objective, the steps and the check for understanding. A visitor who is not signed in can send about 2000 characters. The box holds up to 18,500. One class fits; split a unit into one project per lesson.
Read every scene before anything is drawn. Change a sentence, merge two steps, or cut a materials list that the viewer does not need. Hand edits at this stage do not use credits. The scenes share the length you picked. Each scene runs from 3 to 40 seconds, and a project holds at most 16 scenes.
A pen draws each scene while the narration plays, or while captions show the words if you leave the voice off. Export on this device. Keep the page open and in front until the file downloads. Recent Chrome and Edge save MP4; some other browsers save WebM instead.
A useful paste tells the viewer what they should be able to do, then the sequence, then how you will know they followed. Timing notes, seating charts and supply lists usually waste scenes. Name the audience in the first line so the wording stays at the right level.
One sentence the opening scene can say aloud. "Students can name the three inputs of photosynthesis" is a scene. "Cover chapter 4" is not.
Each step should be something a pen can draw: an arrow, a label, a before-and-after. If two steps are the same picture with a new label, say so, and the storyboard can keep them as one scene.
End with one question you would ask while the board is still up. A bank of ten items belongs in the worksheet, not in a 3-minute walkthrough.
The writer aims at the length on the form. This page opens at 3 minutes, which is the lesson walkthrough length; 2 minutes is in the same menu if the class is short, and 5 minutes is the longest a project can be. With a voice-over, the finished length follows the narration so a sentence is not cut off. Stay inside 5 minutes and 16 scenes either way.
For a topic, the scene budget is about one scene for every 5 seconds of the target, and never more than 16. A 3-minute target can therefore use the full 16 scenes, which means several steps will share a scene unless you merge them yourself in review. A fixed script is not rewritten: you get at most 16 scenes whose pictures follow your words.
Opening
the objective, in words a student can repeat.
Middle
one picture per step, labels short enough to read while the pen is still moving.
Close
the check for understanding, with the answer visible after the question.
Cut
homework codes, standards numbers and minute-by-minute timings.
The plan is for the teacher. The lesson walkthrough video is for the person watching. Read the storyboard against this shift before you spend credits on drawing.
| In the lesson plan | In the walkthrough |
|---|---|
| Objective written as a bullet for you | Opening scene says the goal in one spoken sentence |
| Step 1, step 2, step 3 | Each step is a scene, drawn while it is explained |
| Check for understanding in the margin | Closing scene asks it while the board is still up |
| Materials, timing, standards codes | Left out, unless the viewer must see them |
This page starts from the plan you wrote to teach: objectives, sequence and a check. Student notes are the other direction, what a learner wrote down after class, and they are not a separate tool here. Paste the plan, not the notebook.
Continuous math motion, plotted curves and silent formula films live on math animation. Use that when the lesson is a relationship you need to see move. Use this page when the lesson is a sequence of steps on a board, including subjects that are not math.
The drawing style is chalkboard to start, and Whiteboard is in the style list. The page about the style itself is whiteboard animation. A general topic, with no plan attached, still belongs on the AI explainer video maker. Internal policies and procedures belong on the training explainer video page.
Landscape 16:9 is selected. Switch to 9:16 only when the file is meant for a vertical feed.
Nine narration languages are in the form. The words on the board follow the language you pick.
The caps below are the product, not a suggestion. A longer course is several projects joined in your editor.
Length
15 seconds up to 5 minutes. This page opens at 3 minutes. There is no 4-minute choice; 2 minutes and 5 minutes are the neighbors.
Scenes
at most 16. Each scene is 3 to 40 seconds. A 3-minute film can fill all 16, so review is where you merge.
Import
.txt and .md up to 400 KB, or paste. PDF, slides and photos are not read. There is no text recognition on images.
Paste size
about 2000 characters before you sign in. Signed-in text can use the full box, up to 18,500 characters.
Voice
no voice with captions, or one of four voices when voice-over is available. You cannot upload an audio file.
Export
made in the browser. Keep this tab open and in front. The file is MP4 where the browser can encode H.264, otherwise WebM.
Whiteboard, Math and Map
that Style menu is a silent landscape preview. Choose Whiteboard. It does not use the 3-minute Chalkboard Color preset or the scene-by-scene review described above.
Watching the sample is free. Reviewing the storyboard and editing it by hand are free. Drawing the video uses credits. A new generation after you change the plan uses credits again. Exporting the file does not send another AI request. Accounts that have paid can ask for a more careful script, and that option always uses credits.
Prices in USD, before tax.
Free to start
the AI writes up to 5 scripts a day for free once you sign in (3 without an account). Editing by hand and exporting are free on every account, as often as you like.
Plans from $9.90/month
or $8.90/month billed yearly, which gives the most credits for the money. Credit packs start at $19.90 with no subscription and last 12 months, but a plan gives more credits for the money.
After you buy
10 free scripts a day, then scripts use credits like the rest of the AI work, usually 1â2 each, and exports carry no watermark. Accounts that have never bought anything export with a small watermark.
Start with one lesson: the objective, the steps in order, and a single check. Leave the form on Topic unless the text is already the narration. The storyboard is the place to delete supply lists and standards codes before anything is drawn.
The target length is the number on the form, 3 minutes when you open this page. Scenes share that length, each between 3 and 40 seconds, with at most 16 scenes in the project. For a topic, the writer may use up to one scene per 5 seconds of the target, still capped at 16. A fixed script is not rewritten; only the pictures are planned around your words.
No. Student notes are what someone wrote while learning. This page expects the plan you wrote in order to teach. Paste objectives and steps. If you only have notes, you can still paste them, but the storyboard will follow those notes rather than a lesson sequence you did not include.
No. Import text accepts .txt and .md files up to 400 KB, and you can paste. PDF, Word, slides and images are skipped. Copy the lesson text out of the PDF yourself. Nothing on this page reads text out of a picture.
It turns the plan you paste into a scene list and a drawn walkthrough. You approve the scenes first. It does not replace your lesson, grade work, or build a slide deck. The drawing is a pen on a board, starting in Chalkboard Color, not a recording of you teaching.
This page opens at 3 minutes, the usual walkthrough length, and you can switch to 2 minutes or up to 5 minutes. There is no setting between 3 and 5. With a voice-over, the length follows the narration so lines are not chopped, and the project still cannot pass 5 minutes or 16 scenes. Longer courses are one project per lesson.
You can leave the voice off and keep the narration as captions, or pick one of four built-in voices when voice-over is available. You cannot upload a recording or clone a voice. Export a silent file and add your own track in a video editor if you need it.
That Style menu is a silent film preview. Choose Whiteboard, paste the same lesson, and export a landscape file with no voice. It does not list scenes for you to edit, and it does not apply the 3-minute Chalkboard Color preset. Length, Import text and scene review are on the form that opens with Chalkboard Color.
