A guided look at the workflows, not a live application. Product availability varies by use case.
Start with the problem in front of you.
You can use either product on its own.
“Can I use this data?”
Inspect recordings, understand data problems, and review the changes that turn raw sources into a dataset you can use.
Robot datasets · Video · Spatial data workflows
“Is this policy actually better?”
Watch a policy run, investigate a failure, and compare a candidate using the same experiment settings.
Simulation · Investigation · Policy comparison
A derived dataset or a candidate policy should not erase the baseline you need to compare it with.
Open the recording, inspect the selected event, and follow the evidence behind a decision.
Missing observations, untested targets, and regressions should be part of the review.
No. Tether Studio has local simulation workflows. Cupel starts with your recordings or datasets. Hardware integration is a separate step, not a requirement for exploring the products.
No. Cupel focuses on data preparation and review. Tether Studio focuses on policy execution, investigation, and comparison. Choose the one that fits your current task.
Tether Studio supports local simulation, recording inspection, matched comparisons, and supported simulation packages. Cupel has dataset inspection, treatment, evaluation, and release workflows, with video and spatial capabilities at different stages. The product pages describe the current scope; contact us about your specific inputs and target.
Email team@fastcrest.com with the dataset or policy you are working with and what you want to improve. We will discuss fit, access, and the next step for your workflow.
