Questions, answered
Is StoryTool's Motion Lab free?
Motion Lab is free for 10 clips a day, and free clips are kept for 3 days and carry a small StoryTool watermark. Paid plans cost about $0.10 per clip (100 credits), remove the watermark, keep clips for 30 days, and run up to 5 renders at once.
How do I turn a sentence into an educational video?
Type one sentence into Motion Lab and press Generate. StoryTool picks the best visual for it (a chart, equation, map, character scene, and more) and renders a short motion clip with captions, adding a voiceover if you turn Voice on. You can change the visual yourself at any time.
Does StoryTool use real footage or AI graphics?
Motion Lab clips are rendered graphics: charts, equations, diagrams, maps, 3D shapes, and illustrated characters. They are not filmed footage, and StoryTool does not make photoreal video or talking-head avatars.
How accurate are the STEM visuals?
StoryTool draws what you write: your numbers, your equations, your steps. It never solves, balances, or invents the answer, and you review every clip before you publish.
How long are my clips saved?
Motion Lab keeps clips for 3 days on the free plan and 30 days on paid plans. Expired clips are removed, so download anything you want to keep. You can also delete a clip yourself at any time.
How many clips can I render at once?
One at a time on the free plan. Paid plans run up to 5 renders in parallel.
What languages does Motion Lab support?
You can write in 50+ languages. Turn Voice on and the narration matches the language of your sentence.
Do StoryTool credits expire?
Monthly credits are valid for 30 days from each renewal.
What is the difference between Motion Lab and Motion Explainer?
Motion Lab turns one sentence into one short clip. Motion Explainer turns a full script into one complete video, choosing the right visual for every line.
Is my sentence used to train AI?
On paid plans, StoryTool does not use your sentences or clips to train its models. On the free plan, your inputs may be used to improve StoryTool.
