Carnets vs Syntactic

Jupyter notebooks are a powerful tool used in education and research. You can write small snippets of Python code and observe the result on screen, combine with paragraphs of text, using Markdown. Carnets provides a complete, stand-alone, implementation of Jupyter notebooks. Everything runs on your device, using the embedded Python interpreter; you do not need an internet connection. You can chose between Jupyter notebooks and the more advance Jupyterlab using Settings. Numpy, Sympy, Matplotlib, Pandas, lxml, bokeh, nbextensions (including ipywidgets) and many other packages are pre-installed. To see the full list of installed packages, type "%pip list" in a code window. You can add more packages using "%pip install packageName", but only if they are pure Python. If you need scipy, seaborn or scikit-learn, please use our other App, "Carnets - Jupyter (with scipy)". You can share your notebooks with other apps and also open notebooks or directories managed by other apps. Partial list of installed packages: astropy, babel, bokeh, cryptography, cvxopt, Fiona, geopandas, geopy, lxml, matplotlib, numpy, openCV, pandas, pillow, pyFFTW, pyproj, rasterio, regex, shapely, sympy, wordcloud.

Syntactic is a complete Rust learning environment that runs entirely on your device — a real Rust compiler in your pocket. WRITE AND RUN REAL RUST Write Rust in a fast editor with syntax highlighting, inline errors, and code completion, then compile and run it on-device. No account, no server round-trip, no internet required — the actual Rust compiler runs on your iPhone and iPad. LEARN FROM THE RUST BOOK The complete Rust Programming Language book is built in, formatted for comfortable reading, with runnable examples one tap from the editor. Check your understanding with built-in quizzes as you go. PRACTICE WITH CHALLENGES Sharpen your skills with 66 hands-on coding challenges across three difficulty tiers. Write your solution, tap Submit, and an on-device test suite grades it instantly — with the failing case and your own debug output right there when you need them. EXPLAIN ERRORS WITH ON-DEVICE AI (OPTIONAL) Stuck on a compiler error? An optional on-device AI can explain it in plain language, grounded in your own code — downloaded only if you choose, and running fully offline. EVERYTHING ON-DEVICE Your code never leaves your device. There is no sign-in and no tracking. Compiling, running, reading, and practicing all work completely offline, anywhere. Syntactic is an independent, unofficial app. It is not affiliated with or endorsed by the Rust Foundation.
