I searched for a simple, self-hosted journal app for my girlfriend and everything I found was either too
complex, too feature-heavy, too feature-less for what I needed or required trusting a cloud service.
So I built Piruetas (it means lollipops in Spanish - she chose the name btw).
It's a day-per-page diary with rich text editing, drag-and-drop image uploads, auto-save, public
share links, and a clean mobile UI.
It can be set up for Personal or Multi-user usage via docker compose deployment.
She seems to like it so I decided to give back to the community and make it available for everyone (after some QA)

When going abroad, the right plugs are essential to keep your gadgets charged. These are my favorite travel adapters and chargers.

Hi HN,
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.
