A running note of small, single-purpose web tools I built or lean on. Nothing fancy, just things that saved me time.
When I am cramming, I run the numbers through this spaced-repetition interval calculator to decide when to review next, and I paste rough notes into a quick practice-quiz generator before an exam.
For work stuff, I keep a page that lets me compare AI tool pricing side by side, and when a subscription bill creeps up I check how streaming plans stack up and the current subscription deals.
On the finance side I jot down daily market observations and poke at some lower-risk trade planning dashboards.
Two are just for fun: a friend and I maintain a tower-defense codes tracker and a Kaiju Alpha active-code list for a couple of Roblox games we play.
And when I want a walk, these step-by-step walking routes are handy, while this little tool that turns a short story into a custom song made a decent birthday gift once.
Two more I've been tinkering with lately: a community-run Bongo Cat Wiki that catalogs the Bongo Cat game's items and tools, and savtocsv, a browser tool I made to turn SPSS .sav files into CSV without opening any stats software.
Adding one more since I wrote this: https://stampmakertool.com/ builds round company seals, date stamps, notary marks and signature stamps in the browser and exports transparent PNG or SVG. Vector output is the point — a raster seal falls apart the moment it sits on a full-page contract. The fiddly part was curved text on a round seal, where per-character rotation has to be recalculated from the string length or a long company name collides with its own first letter.
