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.
Tests & exams
For lecturersSet tests and exams on the same engine employers assess candidates with: a different version of the plant for each student, designs re-solved on our servers, written answers marked against a rubric with second markers, timed or live sittings, grades on your own scale, feedback and results released when you choose, extra time for students who need it, and grades sent back to your LMS. The simulator stays free; tests & exams are the premium part.

- A student counts once a year, however many tests they sit.
- Billed yearly. Your tests and marks stay readable if you stop.
- Whole department or university? It goes on the licence, shared by every lecturer.
- Students need no account and pay nothing.
Want the simulator free for your university? We sponsor the simulator for selected universities. Tests & exams are never part of a sponsorship, but you can ask for a quote in the same application.

Campus & Enterprise
Seat-based licensing for schools, universities and training teams.
seat-based · billed per teacher & student seat
Schools, university departments, corporate training programs
- Everything in Pro, for every seat
- Separate teacher and student seat pools, sized to your cohort
- Members join automatically with your verified email domains — or an invite allowlist for personal addresses
- Admin dashboard: manage members, watch seat usage, promote teachers
- Instructor tools: classrooms, auto-graded assignments, gradebook
- Priority support and onboarding for faculty
- Purchasing-power-adjusted pricing; Enterprise plan for unlimited seats
Campus & Enterprise seats
Which plan fits is decided by who is buying — an instructor for their own course, a department for a programme, or a school for everyone. 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. Every plan carries the whole simulator, Classes, Connect, the AI Tutor, auto-graded assignments and LMS integration. We quote after a short conversation, and 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.
+ Assessments (tests & exams)
Lecturers set tests and exams on the assessment engine: a different version per student, design checks re-solved on our servers, rubric marking with second markers, timed sittings, live vivas, grades and feedback released to students, and grades sent back to the LMS. Metered by students assessed per academic year.
+ LensaSim Plant
Process-control and operations training on a 3D virtual plant: missions scored on what the plant did, the control-room view, teams with assigned and assessed missions, and candidate assessments for hiring. By custom quote; every member of the licence gets it.
Mention which you want when you get in touch — it can also be changed mid-contract.
LensaSim Hire
Assess and hire process engineers
Candidate assessments on real design work, talent search over published simulations, and standing hiring briefs. Priced by how many people you assess, on its own site.
LensaSim Plant
Process-control and operations training
A 3D training plant — oil & gas production, refining, gas processing — with missions scored on what the plant did, teams with assessed missions, and candidate assessments for hiring. By custom quote: for a whole organization (added to its licence) or for named people. Already a LensaSim subscriber? It is added alongside what you have. The first mission is free to try, no account needed.
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.
