Physics · Chemistry · Biology · Maths · AI · Robotics — all mapped to NCERT chapters. Built for CBSE Class 6 to 12.
Search by topic, filter by subject or class. Every simulation opens instantly in your browser — no download, no Java, no app needed.
Every question PhET or OLabs users have — answered here, with a better solution.
PhET uses Java and Flash for older sims. TrySpyral sims are 100% browser-native — no Java, no Flash, no plugin needed.
PhET has limited Hindi support. TrySpyral has full Hindi interface — switch with one click.
PhET pages don't mention CBSE, NCERT, or class numbers. Every TrySpyral sim shows the exact NCERT chapter and class.
PhET's biology catalog is thin — mostly genetics. TrySpyral has 17+ biology simulations: cell division, DNA, photosynthesis, heart, neurons, and more.
PhET has zero robotics content. TrySpyral has Arduino simulator, 3D robotics assembly lab, and drone FC builder — all free.
OLabs is a government portal — slow, requires registration, no AI. TrySpyral: no login, instant load, AI-powered quiz after every simulation.
Students search for worksheet answers to understand concepts. Our AI Explain mode walks through the concept step-by-step — better than an answer key.
Energy Transformation Visualizer and Circuit Builder are live on TrySpyral — with CBSE Class 11/12 chapter tags and AI quiz.
Practice every CBSE board practical online. Ideal for Class 9, 10, 11, and 12 students who want to prepare for practicals at home — or teachers who need a lab without hardware.
Why TrySpyral Virtual Lab beats OLabs for board exam preparation:
The only platform that covers CBSE AI curriculum (Code 417 for Class 9-10, Code 843 for Class 12) with hands-on tools. PhET has zero AI content — this is entirely our territory.
Real Python in browser. No installation. Supports numpy, pandas, matplotlib. Class 11-12 CBSE.
Open IDETrain real ML models — linear regression, decision tree, neural net. Full Iris + custom datasets.
Open ML LabSee how neurons fire, weights update, backprop works — visual, interactive, no math degree needed.
Open NN VizUpload CSVs, visualize distributions, find correlations. Real data science for Class 9-12 students.
Open Data LabSentiment analysis, word embeddings, text classification — CBSE AI Chapter 5 topics made interactive.
Open NLP Lab6 CBSE AI ethics case studies with stakeholder analysis. Code 417 Chapter 4 exam-ready.
Open Ethics LabBuild, wire, and simulate robots entirely in your browser. No Arduino board, no motors, no wires needed. Perfect for Class 8-10 students and robotics clubs.
Drag and drop chassis, motors, sensors. Wire them up. Press Run — robot simulates in 3D. Auto-generates Arduino .ino code.
Open LabDesign a flight controller from sensor selection to firmware. AI writes the code. Flash via browser — no app needed.
Open Drone LabBuild and test circuits — resistors, capacitors, LEDs, transistors. CBSE Class 10 Chapter 12 mapped.
Open Circuit LabUltrasonic, IR, temperature, gyroscope — simulate sensor readings without physical hardware.
Open Sensor LabPhET gives teachers simulations only. TrySpyral gives simulations plus the full assessment layer — questions, worksheets, progress tracking, and reports. Everything a teacher actually needs.
Enter any topic — get 20 MCQs, 10 short answers, 5 long answers instantly. CBSE pattern, exam-ready.
Auto-generate printable worksheets aligned to NCERT chapters. Save hours of prep time.
See exactly which student attempted which simulation, their quiz score, and time spent. Real data, not guesses.
Generate competency-based NEP 2020 progress reports per student in under 60 seconds. No manual entry.
Every simulation has an embed code. Add interactive labs to your school website or Google Classroom in one click.
Assign specific simulations to your class. Students open on their phones — you see completion in real-time.
An honest comparison of the top platforms for CBSE science learning in 2026. Free simulations, AI tools, and teacher features side by side.
