Math & ML tools are the same
Everyday Math & Data Science tools
To save time and even bring some joy
  • Calculators
    Tools to evaluate expressions working with numbers, letters, matrices and plots

  • Graphs & NN visualization
    Many aspects from input to analysis are way easier to do visually. Neural Network and graphs with more than two components are good example of that.

  • Notes writing
    For those who loves to think with a pencil in a hand and want to get rid of paper, be able to backup and share ones notes in realtime.

Calculators
Desmos
Amazing tool to compute formulas & build graphs. Allows to input expressions in LaTeX-like format, has built-in statistic functions. Drag the points on a plot:
Derivative calculator
Really usefull service to make sure your Loss derivative is correct, or when you're deriving Hessian for some cool multi-parameter distribution.
Integral calculator
The same as derivative calculator but for integrals. Time after time spit-out really nice formulas that are easy to work with and save a lot of time!
Symolab
Has a lot of functionality. Irreplaceable for matrices operation in algebraic not numerical form. Input is a bit less convenient than Desmos, but matrices are only Desmos serious flaw.
Geogebra 3D Calculator
One of the best tools when you need a 3D plot and you need it now. Very similar to Desmos, but a bit less handy : )
Visualizers
CS Academy Graph Editor
Nice, sweet and simple directed/undirected graph editor
CS Academy Graph Editor
Professional graph editor. Support export / import in .json format
TensorFlow playground
Tinker With a Neural Network Right Here in Your Browser.
Don't Worry, You Can't Break It. They Promise :)
Notes
Tools below are best for happy owners of iPads or Samsung Notes supporting pen.
  • You can add multiuser handwritten updates to the same note in realtime. Drag&drop vector graphics, images and icons.
  • Keep an active part of a note opened on a table while whole the rest of it on a huge screen in front of you.
Cost $10 / month. Shows changes you make, like added images or hand-written formulas in real-time. Allows easily add cool icons / vector arrows and many other things. Not always perfectly works with pen input:
MIRO
Free. Best for daily notes. Notes undistinguishable from the real paper. Nice organizing. Few times a day has cross-devices sync delays up to 5-10 minutes. So not perfect for a realtime collaboration.
Microsoft One Note
