Molecular systems
Inspect molecules, ligands, proteins, and structural context.
Vicena Compute, powered by Rowan for advanced modeling
Run advanced computational chemistry inside Vicena.
Prepare modeling workflows, run bounded simulations, inspect the outputs, and iterate toward the next scientific decision, all inside the same workspace.

Real computational work
Move beyond AI summaries. Run molecular analysis, modeling, and simulation workflows directly from your research workspace.
High-performance chemistry
Use scalable compute for more advanced chemistry tasks when lightweight analysis is not enough.
Work from context
Start from a paper, molecule, protocol, assay condition, or experimental result - not from an empty tool interface.
Iterate inside Vicena
Review outputs, refine assumptions, compare candidates, and decide what to test next.
Not just AI answers. Scientific work execution.
Focus on the chemistry, not the infrastructure.
Most AI tools can explain chemistry. Vicena is built to help scientists do chemistry work.
Describe the scientific goal, prepare the computational workflow, run bounded jobs, and inspect the results in notebooks, plots, structures, and summaries.
The value is not another chat interface. The value is enabling researchers to move from question to computation to decision.
Computed outputs you can inspect
From simulation files to scientific decisions.
Vicena keeps computational outputs visible and usable: molecular structures, notebooks, tables, plots, scores, logs, and summaries.
Scientists can inspect the result, question it, compare alternatives, and use it to decide the next step.
Vicena-generated docking result
Work on the scientific objective, not the tools.
This image is one example: a docking computation where a ligand is placed inside a protein binding pocket for inspection.
With Vicena, the scientist starts from the question, a molecule, protein, paper, assay result, or experiment, and Vicena helps prepare the right computational workflow around it.

Examples of work scientists can start inside Vicena Compute:
Scalable compute access
Included credits. Top up when the work grows.
Vicena plans use shared account credits for eligible computational chemistry, AI, notebook, and tool workflows.
Free does not include Rowan or external simulation workflows. Plus and Ultra include exploratory work inside the subscription; larger or repeated simulations can use manual top-ups and pay-as-you-go usage.
Per-job limits help teams scale compute while keeping spend under control.
Compare plansShared monthly credits for eligible workflows.
Manual top-ups should extend the same account budget for AI, notebooks, Rowan, and future services.
Per-job limits to reduce runaway spend.
Team usage controls for shared research budgets.
