## What is Pythona?

Run Python — and large language models, fully on-device — right on your iPhone and iPad. Pythona is a full-featured Python 3.14 IDE that brings real scientific computing, notebooks, and local AI to your device.

Jupyter-style notebooks
Write and run Python in cells, just like Jupyter — charts, tables, images, and math render inline. Open, edit, and save .ipynb files to run data analysis and experiments anywhere.

On-device AI & machine learning
Run large language models entirely on-device with MLX, Apple's ML framework for Apple Silicon — inference runs locally, no API keys required. Try the included local LLM demo to get started in seconds.

Scientific computing, preinstalled
NumPy, SciPy, scikit-learn, Pandas, Matplotlib, OpenCV and more come precompiled and ready to import.

A local Python environment
- Python 3.14 with popular libraries
- Smart, fast code completion
- Syntax highlighting for many languages (JavaScript, C, Rust, Go, HTML, CSS, Shell, and more)
- Markdown file preview
- Create, save, and organize your scripts, and install more pure-Python packages via the built-in package manager

Whether you're prototyping ML ideas, running data analysis, or learning Python on the go, Pythona puts a genuinely capable Python environment in your pocket.

### 1/5 — 这也太难用了吧

*2026-06-11*

直接卡到爆，纯骗人的垃圾

### 5/5 — Works great, fantastic support

*2026-05-20*

It works as described, a current python version, easy installation of packages etc. What was best so far is the support. I needed mlx to run llms locally on my ipad, and the package was added within hours and fully working within days. Incredibly good and friendly support.

直接卡到爆，纯骗人的垃圾

### 5/5 — New feature request

*2026-04-05*

希望能增加可以引入外部文件夹的功能，以外部文件夹作为运行路径，比如iCloud或者one drive下面的文件夹，每次复制很麻烦

**Developer response:** 感谢您的支持和建议，这个需求我们已经关注到，后续会继续完善文件夹访问与使用体验，感谢反馈。
