Show HN: Mljar Studio – local AI data analyst that saves analysis as notebooks

I’ve been working on mljar-supervised (open-source AutoML for tabular data) for a few years. Recently I built a desktop app around it called MLJAR Studio.

The idea is simple: you talk to your data in natural language, the AI generates Python code, executes it locally, and the whole conversation becomes a reproducible notebook (*.ipynb file). So instead of just chatting with data, you end up with something you can inspect, modify, and rerun.

What MLJAR Studio does:

- Sets up a local Python environment automatically, runs on Mac, Windows, and Linux

- Installs missing packages during the conversation

- Built-in AutoML for tabular data (classification, regression, multiclass)

- Works with standard Python libraries (pandas, matplotlib, etc.)

- Works with any data file: CSV, Excel, Stata, Parquet ...

- Connects to PostgreSQL, MySQL, SQL Server, Snowflake, Databricks, and Supabase.

For AI: use Ollama locally (zero data egress), bring your own OpenAI key, or use MLJAR AI add-on.

I built this because I wanted something between Jupyter Notebook (flexible but manual) and AI tools that generate code but don’t preserve the workflow. Most tools I tried either hide too much or don’t give reproducible results and are cloud based

Pricing is $199 one-time, with a 7-day trial.

Curious if this is useful for others doing real data work, or if I’m solving my own problem here.

Happy to answer questions.
