# Priodemy

> Priodemy is an AI-first technology company building interconnected software that helps people learn, work and build. Its tagline is "One Ecosystem. Endless Possibilities." priodemy.com is the free learning platform at the centre of that ecosystem, covering three tracks: **coding** (14 structured programming courses, 290+ interactive lessons, 1400+ quiz questions, an in-browser playground and multi-language code runner, and verifiable ProdiFy certifications), **school academics** (Priodemy for School — CBSE/NCERT-aligned Class 8–12 chapters in Maths, Science, Physics, Chemistry, Biology, English and Computer Science, with 25 hands-on interactive simulations) and **software projects** (Priodemy Projects — complete student projects with source code, database and documentation). Everything on the site is free to read — no sign-up required.

Key facts:
- 100% free to read and learn; funded by ads and optional paid certifications.
- 14 courses spanning web development, programming languages, databases, tools, and hardware.
- 255 CBSE Class 8–12 chapters, each with notes, a reference sheet, a practice quiz, and worked NCERT & previous-year (PYQ) solutions — 2,100+ practice questions in total.
- 25 interactive simulations (circuits, ray optics, projectile motion, titration curves, 3D vectors and more) — the "interactive-first, not video-first" approach is the core of how Priodemy teaches.
- 51 complete software projects, 27 of them free to download, each built around one idea worth understanding rather than just code that runs.
- Practice runs in the browser — no installation needed.
- Progress tracking, streaks, and a personal dashboard available with a free Google sign-in.
- Certifications are verifiable at a permanent priodemy.com/verify URL.
- Priodemy is a company, not a single website: alongside this platform it builds Priodemy Labs, EduSuite, PDFrio, Priodemy Office 24×7 and Priodemy Games. See "The Priodemy ecosystem" below.
- Engineering principles, applied across every product: fast by design, private by default, offline-first, AI-ready, built to last.

### Interactive simulations

Hands-on simulators students can manipulate directly — drag the object, change the field, sweep the frequency — with every reading computed from the real formula, not a canned animation.

- [Series & parallel circuits](https://priodemy.com/school/electric-circuits): Build a circuit and watch Ohm's law happen.
- [Ray diagrams for mirrors](https://priodemy.com/school/mirrors) and [lenses](https://priodemy.com/school/light-lenses): Move the object, watch the image form.
- [The pH scale](https://priodemy.com/school/ph-scale): Slide the pH and see what each indicator shows.
- [Projectile motion](https://priodemy.com/school/projectile-motion): Drag the velocity vector and watch the parabola.
- [Titration curve](https://priodemy.com/school/titration-curve): Strong vs weak acid, and why the equivalence point isn't always pH 7.
