Explore the features
Search a project, run a script, read a failing test or ask about a function — and try each tool on one of the twelve bundled projects. Python and the common libraries are already inside; Git, the Terminal, the Python Console, debugging, packages and the profiler arrive with the free Helper.
The Mac tools shown here are included in the free Mac download. App Store features and purchases are listed separately.
Something to try them on
Every tool below has a bundled project to practise on, and the Learn panel holds the material to go with it.
From a personal greeting to a Qt desktop app, a PyTorch image classifier, a FastAPI service and an offline document search. Seven run with the Python already in the app; four need the free Helper and a project environment.
Explore the example projects →Six lessons, eight example scripts, seven short guides to the app and a 31-chapter Python book, all inside the Learn panel.
See the learning material →Ask about the open file with a local Ollama model, Apple Intelligence on macOS 26 or later, or your own Gemini or Anthropic key.
Explore AI assistance →Editing and navigation
Search across a project, jump through the structure of a file and bookmark useful locations. Work with completion, folding, multiple selections and column edits.
Execution
Execute the selected file with saved arguments, environment variables and a working folder.
Explore Run →Use Python Console to inspect objects and try expressions. Use Terminal for shell commands.
Explore console and terminal →Pause on a breakpoint, step through the code and inspect values. Needs the free Helper.
Explore debugging →Git, the Terminal, the Python Console, debugging, packages and the profiler need the free Helper, a separate download. Examples also need project dependencies. Follow the setup guide.
Tests, coverage and profiling
Read a failing test, identify code your tests have not covered or find a frequently called function. Use the result to decide where to focus.
Review passing and failing cases, open their source and rerun failures.
Compare per-file coverage and find gaps in your test suite.
Inspect execution time and call counts, then filter to the function you want to investigate.
Project tools
Review differences, make local commits and work with branches.
Explore Git →Organise folders, save copies and compare earlier versions of a file.
Explore file tools →Read formatted Markdown, HTML, SVG and saved notebook output beside source.
Explore previews →Ask about selected code with your chosen service or a local Ollama model.
Explore AI →Arrange panels, detach tools and choose editor and project preferences.
Arrange your workspace →Inspect connection and tool readiness for Docker and supported cloud services.
See supported service setups →Python environments and packages
Python and useful libraries are included. For projects with additional requirements, choose an interpreter and prepare an environment with its own dependencies.
Work with tables, arrays, charts, images and web requests using familiar Python libraries.
Explore libraries and examples →Use Helper to prepare a project environment and install the dependencies declared by an example.
Set up an environment →Check installed packages, search by name and inspect the details of a dependency.
Use the package panel →Choose the app for your work
