Sketch mechanics, wire circuits, build logic, fire photons at a double slit — then press Play. One canvas, real physics, real Kirchhoff, real interference. Everything editable while it runs.
Mechanics
Rigid bodies, springs, hinges, motors — drawn, then simulated.
Circuits
Kirchhoff-solved R/L/C, diodes, op-amps at 120 Hz.
Digital logic
Gates to flip-flops, every pin live.
Electromagnetics
Waves, fields and photons at real dimensions.
Quantum
Double-slit photons, wells, tunneling barriers.
Algorithms
C++ runs in the page — data structures animate live.
DSA Lab
A C++ interpreter lives inside the notebook. Step through your own code and watch arrays, stacks, trees and graph traversals animate as textbook-quality visualizations.
Local AI agent
Ask for “a projectile hitting a spring on an incline” and the on-device AI assembles it from real simulation components. Nothing leaves your machine.
Docs & PDF notebooks
Pages now come in three kinds — infinite Board, paged Doc that exports to high-quality PDF, and uploaded PDF/PPT you annotate with the pen.
Tabs & split screen
Open several boards, docs and PDFs at once in header tabs, drop any two side by side in a resizable split, and take linked per-page notes.
Every card below is the real engine rendered small — the same solver, the same ink, the same math you get on the canvas.
Pendulums, springs, collisions — gravity and air drag are just variables you edit, even mid-swing.
Amber dashes are conventional current; blue dots are the electrons drifting the other way. Speed tracks the real amps.
Every pin wears its 0 or 1. Toggle inputs with a click while the clock runs.
Freehand recognition turns sketches into circles, rects, springs and wires — meaning comes from behaviors.
Stiffness is an expression. Type k = 20, plot ω₀ = √(k/m), then change k and watch both react.
Plot channels, your own formulas, phase portraits — with custom axes, scales and reference lines.
Build a double-slit experiment on the canvas — a coherent source, a slit mask, a screen — and SIMBLIP performs a Huygens–Fresnel phasor sum over the open apertures at real dimensions (1 px = 1 µm). The single-slit diffraction envelope and the cos² fringes emerge from the wave equation, not from a picture of them. Press Play and photons land one at a time at Born-rule positions, building the interference pattern from individual detections — the experiment that defines quantum mechanics, reproduced faithfully in your notebook.
Huygens–Fresnel
Every open slit is summed as secondary wavelets — Σ e^{ikr}/√r. Change λ, gap or spacing and the fringes respond exactly as theory predicts.
Born rule photons
In Play mode single photons accumulate stochastically from |A|². Watch randomness become the interference pattern.
Wells & barriers
Particle-in-a-box eigenstates and tunneling transmission, solved from the Schrödinger picture with live parameters.
SIMBLIP is not a lone notebook — it is the environment an engineering institution runs on. Teachers teach from it, boards present it, students submit through it.
1 · Scan
Every classroom display shows a rotating QR. A teacher scans it with their phone and picks any notebook page.
2 · Present
The board loads a temporary copy — annotate, simulate, rewind. The original teaching material is never touched.
3 · Assign
Any page becomes an assignment. Each student gets their own working copy and submits from their notebook.
4 · Review
A live dashboard tracks opened → in progress → submitted → reviewed, with feedback flowing back instantly.
Sketch a shape, attach a Rigid Body — it falls, collides, spins. A zigzag stroke is already a spring.
Batteries, R/L/C, diodes, transistors, op-amps solved with real Kirchhoff analysis at 120 Hz.
Ink that touches a terminal conducts — watch conventional current and electron flow move through it.
Gates, adders, flip-flops, decoders — every pin shows its 0/1 live; click inputs while it runs.
Every field takes an expression. Define g, k, R once — sweep them mid-simulation.
Voltmeter, ammeter, probes and graphs with custom formulas, axes and reference lines.
Write real C++ in the notebook — an in-browser interpreter steps arrays, trees, graphs and sorts as live visualizations.
Describe an experiment and the local AI agent assembles it from real components — private, on your own machine.
Infinite whiteboards, paged documents that export to PDF, and annotatable PDF/PPT readers — side by side in tabs.
SIMBLIP is licensed to universities, colleges and schools as a complete engineering education platform — role-based workspaces for admins, teachers and students, QR-paired classroom boards, an institution library, and a live assignment workflow. There is no public sign-up: your institution is provisioned for you, branded as yours.
