How it works
From idea to finished video in three steps
AI builds the visual explanation
LongStories.ai generates animated visuals that illustrate each part of the explanation as it unfolds - not a person talking about the concept, but the concept itself being shown.
Review and share
Your explainer is ready. Embed it in your product, drop it in your course, share it on LinkedIn, or hand it to a sales team. Download in any format you need.
Features
Built for the way creators actually make videos
These pages are specific because each generator has a different job: music videos, scripts, animation, kids stories, documentary topics, and character-driven series.
Visuals that explain, not just illustrate
Most explainer tools show a person talking about your concept. LongStories.ai generates animated visuals that demonstrate the concept - cause and effect, before and after, step by step.
No avatars, no stock footage
No AI presenter reading a script. No generic B-roll that has nothing to do with your product. Every visual is generated specifically for what you're explaining.
Any complexity level, any audience
Beginner-friendly overviews or deep technical explanations. Define your audience in the prompt and LongStories.ai calibrates the language, pacing, and depth accordingly.
Product, concept, or process - all covered
SaaS product demos, scientific concepts, financial explanations, operational processes, educational lessons. If it can be explained, it can be animated.

Who it's for
Who Makes Explainer Videos With This
SaaS founders and product teams
You need a product explainer that actually shows what your product does - not a screen recording with a voiceover, and not a generic animated template. Describe your product's value in plain language and LongStories.ai builds the visual explanation around it.
Educators and course creators
Your course covers concepts that are hard to explain in text alone. LongStories.ai generates short animated explainers for each concept - visual, memorable, and specific to what your students need to understand.
Marketers explaining complex services or offerings
Your service is nuanced and your clients need to understand it before they'll trust it. Generate explainer videos that walk prospects through how it works, what they get, and why it matters - without a production team or agency.
