The AI platform for your science and engineering challenges.
You do the science. Lemma does the rest.
Start with a problem like these.
Search the literature
I have a ridged waveguide I have been trying to build. But I think my problem, backreflection and a large Fano factor in my modulator, might be from some other source. Can you search for papers that have dealt with this problem in nanophotonics?
Create a research plan
Decompose the problem I provided into a research plan of intermediate claims, each with its stated inputs and a numerical check. Propose which to attempt first and why, and which look easiest to formalize.
Run a simulation
Simulate a quantum quench in a Heisenberg 6-spin chain from the Néel state: magnetization dynamics, entanglement growth, and the correlation light cone.
De-risk a design
I am making a ring resonator system to use as a local probe of temperature. The light circulating in the ring will cause thermo-optic and other nonlinear effects. Can you find works that help me calibrate that effect, and design against it impacting the temperature sensing?
Derive across scales
Start from the compressible Navier–Stokes momentum balance and derive what it reduces to in microfluidics, in the atmosphere and ocean, and in magnetized astrophysical gas. Include the dimensionless number behind each, and a table of what's dropped, what's added, and what must be modeled.

Science, without the tedium.
Bring Lemma the work that takes a week when you only have a morning. You direct the approach and approve the plan. Lemma does the work: managed, verified, and reported back.
Approved specifications
You set the direction: refine the plan, compare approaches, and set the specifications each step must meet. Nothing runs until you approve, and when a step fails, Lemma asks again.
Managed environment
Lemma runs the solvers, simulators and optimizers of your field, and installs anything else on request. No setup, no version conflicts.
Verification pipeline
Lemma checks results as they are produced for consistency, coherence, and agreement with sources, and reports when an output doesn't yet meet your specifications.
Interactive reports
Lemma reports back in interactive notebooks, where code and plots annotate the outcome. Portable anywhere.
