Question 1

What is Val Engine?

Accepted Answer

Val Engine is an AI infrastructure API for adaptive learning, built by Plusfinity. It generates live, visual, interactive learning experiences in real time — not videos, PDFs, or text answers. EdTech platforms, AI tutors, schools, and online learning products integrate Val Engine via a single REST API to deliver personalized, adaptive lessons at scale.

Question 2

Is Val Engine a Manim alternative?

Accepted Answer

Yes. Manim is a Python library that requires developers to hand-code each animation frame. Val Engine is an API that generates interactive math and science visualizations on demand — no Python, no scripting, no rendering pipeline. Unlike Manim, Val Engine scenes adapt in real time to the learner's inputs, making them interactive rather than pre-rendered video clips.

Question 3

How is Val Engine different from Khan Academy?

Accepted Answer

Khan Academy delivers pre-recorded video lessons that are the same for every student. Val Engine is an API that generates live, interactive learning scenes that rewrite themselves in real time based on each student's inputs, confusion points, and questions. Developers and EdTech platforms can embed Val Engine into their own products to deliver Khan Academy-style explanations that actually adapt.

Question 4

Can Val Engine generate AI-powered interactive math videos?

Accepted Answer

Val Engine goes beyond video. Instead of generating a static video file, it generates a live, interactive scene where learners can drag points, move sliders, and explore concepts hands-on. This is more effective than AI-generated video because the content responds to the learner rather than playing linearly.

Question 5

Who is Val Engine for?

Accepted Answer

Val Engine is built for EdTech companies, AI tutoring platforms, online learning providers, K-12 schools, universities, course creators, LMS providers, test prep companies, corporate training programs, and any developer or product team that needs to teach a concept interactively — including those looking for a Manim alternative or a way to generate Khan Academy-style interactive content via API.

Question 6

How is Val Engine different from a video or PDF?

Accepted Answer

Videos and PDFs are static — they cannot adapt to a learner's confusion or curiosity. Val Engine generates fully interactive, real-time scenes that respond to each student's input, dragging, sliders, and questions. Every lesson adapts on the fly to the individual learner.

Question 7

What subjects can Val Engine teach?

Accepted Answer

Val Engine is optimized for math (geometry, algebra, calculus), science (physics, chemistry, biology), and STEM topics, with interactive visualizations for concepts like the Pythagorean theorem, slope, triangle angles, forces, and more. The engine is expanding to coding, finance, languages, and humanities.

Question 8

How do I integrate Val Engine into my product?

Accepted Answer

Val Engine is delivered as a single REST API. You request a lesson with a topic prompt, and the API returns a live, interactive scene you can embed in your web app, mobile app, LMS, or AI tutor. Request API access at https://useval.io/.

Question 9

Who built Val Engine?

Accepted Answer

Val Engine is built by Plusfinity — a team of founders from Cornell, NYU, and Freightos with backgrounds in AI, education, and infrastructure software.
