Plans & pricing
Simulation is free for everyone, always — it runs in your browser and costs us nothing per run. Paid plans fund what does cost money: AI inference, cloud storage and support. That keeps LensaSim sustainable without ever locking students out of learning.

Verifiable certifications
$19–$29 per certificate · Pro from $12.35A subscription buys the learning; the credential is a separate, one-time step. Issuing a verifiable certificate — with a public verification link — is a one-time fee per certificate. Pro members pay a discounted rate, and Campus plans include issuance for the whole cohort. Free learners can study every lesson, but a certificate is not included.
1 · Learn & practice
Every guided lesson is free. Pro adds the graded assessments and the AI tutor you need to pass them.
2 · Issue the certificate
A one-time fee per certificate once you've passed its modules and capstone — discounted for Pro, included on Campus.
Earned free
The Certified Process Simulation Engineer meta-credential is awarded free once you hold its prerequisite certificates.
Campus & Enterprise seats
Institutions buy two pools of seats — teachers and students — sized to their cohort. Members are admitted automatically through your verified email domains (or an invite allowlist for personal addresses), and an org admin manages seats and members from the Teachers page. We provision your license after a quick conversation; pricing is purchasing-power-adjusted for institutions in emerging economies.

Choose your scope
Every licence covers the whole simulator and the learning platform. Tell us what else belongs in the agreement and we provision it on the same licence — no second subscription, no separate billing.
Learning & simulation
The default. Simulator, courses, assignments, certifications and classroom management for your teacher and student seats.
+ Recruiting & talent search
Search members by published work and verified credentials, keep shortlists, and see the contact details members chose to publish — for placement offices, graduate schemes and internal mobility.
Mention which you want when you get in touch — it can also be changed mid-contract.
Why is AI behind the paid tier?
Every AI request costs real money in API inference. To keep the free tier free forever, features with per-use cost — the AI process assistant, AI property estimation, advanced thermodynamic guidance — sit on Pro. Everything that runs locally in your browser (the entire simulation engine) stays free.
Affordable where it matters
Pro is priced at $5/month — deliberately within reach of students. Campus plans use purchasing-power-adjusted pricing so a teaching lab in Lagos or Nairobi pays in proportion to local budgets, not Houston ones. Contact us for institutional pricing.
What LensaSim is — and is not — for
LensaSim supports education, corporate training, academic exercises, conceptual design and research. It is not licensed for final commercial engineering design: parts of the experience can rely on AI-estimated property data, and engineering decisions that affect safety, money or the environment require validated tools, measured data and professional review.
How do payments work?
Sign in with just your email (we send a 6-digit code — no password) and upgrade through Stripe; your plan is then verified server-side on every AI request, with daily usage quotas. Academic emails automatically qualify for student pricing. Deployments without billing configured fall back to evaluation mode below.
