I taught myself to notice how bad my typing was, then spent a summer fixing it (and building a tool to help)
For most of my life I typed fine. Fast enough, good enough, nobody noticed. Then I started a physics degree where every lab report, every problem set, every late-night email to a professor ran through a keyboard, and “fine” started costing me time I didn’t have.
So I did the thing every typing article tells you to do and went back to basics — home row, proper finger placement, the whole humbling process of typing worse before typing better. What I noticed is that almost every typing tool I tried measured the wrong thing. They’d show me a words-per-minute number that went up even on days I made a mess of every third word, because they were counting raw keystrokes, not net accuracy. That’s not a measurement of skill. That’s a measurement of how fast you can mash a keyboard.
I ended up building my own tool this summer — WorkThoseKeys (workthosekeys.com), which started life as TypeCast and briefly went by Typefast before I settled on this name. It tracks net WPM, which actually penalizes errors, and it goes one step further than most tools I tried: it tracks which specific letter pairs trip you up, not just which letters, and builds practice around that.

It also has an AI coach that translates all that error data into actual advice — plain sentences about what to work on, instead of a table of percentages you have to interpret yourself.
The part I didn’t expect to love: book mode. Instead of generic practice text, you can type your way through real public-domain literature — short poems if you want something you can finish on a coffee break, or the entirety of Moby-Dick if you want a project that’ll take you months. Your position saves between sessions either way.
I’m not a professional developer — I’m a physics student who also teaches sailing — so I built this using an AI-assisted app builder rather than writing everything by hand. That’s a separate story. The short version of this one is: if your typing tool is telling you a speed you’re proud of, it might just be lying to you a little. And it’s free, with a guest mode if you’d rather not sign in at all.
