Is there an online tool that generates the corresponding LaTeX code of a diagram which can be drawn using a graphical interface? A tool such as latexdraw but only using a web browser (like Detexify)?

1@Karlo Thanks for the heads up. Apparently https://github.com/kjellmf/svg2tikz is the new way of doing that. – JLDiaz Jul 19 '17 at 16:00

A wonderful option is mathcha: www.mathcha.io
just open the editor, you log in and you make your drawings and equations.
this online program will create different export formats, including Tikz, which is compatible with Latex.
Edit:
I see that some people cannot find the menu to export, simply by clicking on the drawing grid, you should notice that a menu appears at the top, you can see the option that says "Tikz", if you click on the triangle on the right side of that button, the option "Copy tikz to clipboard" appears, which is very handy, or even better, you can memorize the keyboard shortcut: Ctrl + Shift + j.
I want to take the opportunity to comment on another very important function, and it is the one that I point out in the image, called "options" there you can activate or deactivate the "Snap to grid" option, that allows you to align much better the lines or other objects that are being inserted in the drawing, this is very useful. Another interesting feature is to draw with the mouse to look for a latex character that you don't remember or don't know, after clicking on the grid and selecting "fx" in the tools on the right side, press the back slash key "\" and the following appears, at the bottom is the "Drawing" option:

3Where is the PDF export function? I couldn't locate it anywhere. Besides, I can't export the TikZ code (it exports nothing except some opening and closing tags). – Jim Raynor Jun 13 '18 at 22:23
-
4It was a nasty surprise, after spending quite some time creating a drawing, that most of the code exported consisted of remarks saying such code cannot be exported. – Martin Argerami Jun 06 '20 at 21:29

Looks like this website does not provide tikz creator anymore. Can someone please confirm – Charith Sep 27 '21 at 04:49

Sorry my bad. You just have to select the drawing area and then it is all good! – Charith Sep 27 '21 at 05:06

The GeoGebra online tool, which can also be installed and run locally, comes to mind. It let's you do geometric drawings: define points, intersections, ellipses given the two foci and a point, etc... It will generate TikZ code for you.
For example, create an ellipse within your browser
This can be exported to TikZ (will generate a standalone document), which renders to

2GeoGebra doesn't make any sense. I tried using it and it keeps producing lines even if when I choose circle. – DrB Oct 05 '17 at 04:40
-
The downside seems to be the standalone export. I don't see any option to directly embed the generated TikZ into my own document. – Makan Aug 16 '18 at 10:47

@MakanTayebi You can easily integrate the file into your own document, see i.e. here. – ViktorStein Apr 07 '19 at 19:38

If you're looking for a tool to draw commutative diagrams with tikzcd, there's Yichuan Shen's tikzcd-editor.

This is the link to run it:
http://homepages.inf.ed.ac.uk/cheunen/freetikz/freetikz.html
Replacing the package with tikz, however, it is possible to observe that the result is not optimal or exact like the figure below.
In fact, we have:
\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\draw (2, 6) to[out=90, in=135] (5, 6);
\draw (2, 6.5) to[out=0, in=180] (5.5, 6.5);
\end{tikzpicture}
\end{document}
For further explanations or informations there is also a link to help the users to use this tool: https://golem.ph.utexas.edu/category/2018/01/freetikz.html

I add one link https://pickedshares.com/en/tikz-online-editor/ named Tikz online editor. Obviously you need to know the language of TikZ.
