Real Python

Not a toy interpreter. CPython 3.13.

The interpreter and every package ship inside the app and run natively on your device. It is the same Python you use on your laptop — the same IPython kernel, the same magics, the same tracebacks.

  • Offline by design. Your code never leaves the device to run.
  • Interrupt & restart. Stop a runaway cell, restart the kernel, keep going.
  • Completion & help. Tab completion and ? help from the real kernel.

Preinstalled

The workflow

Compute in Python. Render on the web.

AnPyer's output area is a full web renderer. Interactive charts, Mermaid diagrams, LaTeX, HTML — anything a browser can draw, a cell can show.

  1. 1Crunch the numbersnumpy, pandas, scipy — the heavy lifting stays in Python, where it belongs.
  2. 2Hand over the resultAsk the assistant to chart it, or call anpyer.plot yourself with a plain dict.
  3. 3Get an interactive chartECharts, plotly, Mermaid, MathJax — rendered right in the output, pinch-zoomable on your phone.

Optional AI assistant

AI that works in the cell, not beside it.

The assistant reads your notebook, proposes edits, and shows you a diff. Nothing changes until you tap Apply. It can add or remove cells — it never runs them for you.

  • Bring your own key. Any OpenAI-compatible provider — DeepSeek, OpenRouter, OpenAI, Gemini, or your own endpoint.
  • Pay the provider, not us. A budget model is plenty for notebook work.
  • Off until you turn it on. Without a key, the app makes no network requests at all.

Your files

Standard .ipynb. Your folder. No lock-in.

Pick a folder with the Android file picker and it becomes your workspace: notebooks, CSVs, images, side by side. Files save as plain Jupyter notebooks that open anywhere.

  • No broad storage permission. AnPyer only sees the folders you choose.
  • Round-trips cleanly. Open a notebook from your laptop, edit on the phone, open it again on the laptop.

Privacy

Nothing leaves your device.

There is no AnPyer server. No analytics, no crash reporting, no telemetry SDK. The only network traffic is the AI assistant you configure — sent straight from your phone to the provider you chose — and any HTTP calls your own code makes.

  • 0accounts to create
  • 0servers of ours
  • 0bytes of telemetry

Good to know

What AnPyer doesn't do.

We'd rather you know before you buy.

  • No pip installThe package set is fixed at build time. Missing something? Tell us.
  • matplotlib is staticFigures render as images. For interaction, use plotly or the built-in ECharts renderer.
  • C extensions can't be interruptedSame as desktop Jupyter: a cell stuck inside compiled code needs a kernel restart.

Pricing

One purchase. That's it.

$4.99one-time

No subscription, no in-app purchases, no ads. Updates included.

The optional AI assistant requires an API key from a third-party model provider of your choice; any fees for that usage are charged by that provider, not by us.
