I got tired of relearning the same words, so I built a memory app

The older I get, the more I forget. A word I looked up in an English book shows up again a week later. An article I found fascinating leaves only its title after a month. Learning new things is a joy; spending time relearning the same things honestly feels like a waste.

Forgetting is natural — the tooling was the problem

Luckily this problem has a proven answer: spaced repetition, showing each card again around the time you would forget it. So I installed Anki first.

It never stuck. The desktop-era UI took studying just to navigate, and above all, making cards was work. Splitting everything into fronts and backs left me exhausted before review even started.

Card-making had to get light first

My conclusion was one line: the barrier to memorizing is not review, it is card-making. So I built an app where you paste text and AI drafts the cards — the word from the book, the fact from a search — and I only pick. Photos of textbook pages and PDFs work the same way.

Scheduling runs on FSRS-5, the scheduler serious Anki users switch on in settings. Each card tracks its own stability and difficulty, pushing solid cards far out and pulling shaky ones back soon. Memento ships with it on by default.

Using it daily, refining it daily

My current routine is simple. An unknown word in a book goes into Memento. Anything new from a search goes in too. Then I clear the day’s review. After a few weeks the difference is concrete: once accumulating outruns forgetting, getting older feels a little less bleak.

Grab it from the intro page or the App Store. If you wonder what to memorize first, pick a study deck and load it in.

I built it to memorize with, so it has rough edges — but that also means it gets fixed daily. Send complaints and ideas to support@hyunsanglabs.com. It genuinely helps.
