What MLJAR Studio is
MLJAR Studio is a workspace for data analysis, machine-learning experiments, and Python notebooks that runs on Linux, macOS, Windows, or self-hosted environments. Ask questions in plain language and it generates Python analysis while leaving the code visible and editable. Its experiment agent can tune models, identify features, compare models, track experiments, and create reports. Studio works with CSV, Excel, and Parquet files, as well as SQL databases including PostgreSQL, ClickHouse, and MySQL. Notebooks can be turned into interactive web apps with Mercury and hosted on your own infrastructure. Processing is local by default; data may go to an outside provider if you configure one or enable the MLJAR AI cloud add-on. With OpenAI configured, prompts and relevant context may be sent under your settings and provider terms. The Free plan is available; Pro is $20 a month and Business is $60 a month. A $199, paid once perpetual license includes one year of updates.
