Gretel alternative: Misata Studio
Prices and facts verified 21 September 2026
Gretel was acquired by NVIDIA in March 2025 and no longer sells a standalone self-serve product: as of mid 2026 gretel.ai redirects to NVIDIA and its technology lives on inside NVIDIA NeMo as Data Designer and Safe Synthesizer, sold through NVIDIA AI Enterprise. If you used Gretel to make believable connected data from a description, Misata Studio does that in your browser: describe what you need, and it builds the tables, gets the numbers you state exactly right, and hands you a certificate that shows it. If you used Gretel to make a privacy-safe copy of real data, or you are already building on NVIDIA's stack, NeMo Safe Synthesizer is the closer successor and Misata is not a replacement for it.

What happened to Gretel
NVIDIA announced the acquisition of Gretel in March 2025, reported at more than $320 million. Since then the standalone service has been wound into NVIDIA's own products: the old site redirects to nvidia.com, the pricing page is gone, and the open-source repositories moved under NVIDIA-NeMo. Anything you built against Gretel's hosted API needs a new home.
If you needed data from a description
Many people used Gretel to get a realistic table when they had no data to start from. Misata Studio is built for that job. You say what you need, for example a dental clinic with 3,000 patients and a 7 percent claim denial rate, and it designs connected tables with believable names, prices and dates. The numbers you state come out exactly, a realism review flags anything an expert would find odd, and a certificate lists every requirement and whether it was met.
If you needed a private copy of real data
That is a different job, and Misata is honestly not the tool for it. Learning from real records and producing a differentially private copy is what NVIDIA NeMo Safe Synthesizer does. If your data cannot be described and must be imitated, use it or a tool built for imitation.
