Simplicity is a virtue borne from life's complications. This is the first public release of the Algs tool.
I made an tool to help people understand F2L because I feel there is a gap out there online. It can be hard to find the best solutions, and even if you do find good ones, it's easy to approach it incorrectly.
Let me explain:
There are a LOT of F2L cases. This site has over 3000 solutions for various cases. Even if you find ways to simplify, learning a bunch of these solutions by just memorizing them would waste a lot of time.
So instead, F2L is taught intuitively. You learn a generalized process for solving things. This process can be slow because it is new to you and you're not used to recognizing anything. It's also nowhere near as efficient as it could be.
So there's too many algorithms to just memorize, and the basic intuitive process is not enough. What do you do?
Extremely good F2L still follows an intuitive process. By understanding the F2L process better, you give yourself opportunities to improve your solutions to multiple cases. For example, if you see a case where you can use R' U2 R to pair two pieces, you might be able to apply that idea to cases that look a bit different.
The Visual search tool will provide solutions like this one above. The full alg is written out up top. If you click on it, a dropdown will open up that shows how you can understand the alg.
On the actual page, clicking the play button will also slowly step through the solution move-by-move. Clicking the will add the alg to your list.
The number of cases makes a traditional list of all algorithms very unweildy for F2L. The visual search tool here is very direct. You just click a few times, and you can set up a case in a couple seconds.

You may have noticed someicons around in places. These are favorite buttons. Clicking it will add it to your list on the Algs page.
Watch out! Algs are saved to your browser. If you clear your cookies, your algs will usually get cleared with them. Make CSV backups. You can import them back in later.
Thanks for reading. Live long, and more importantly, live well.
