Your personal vocabulary algorithm
Every vocabulary app
uses the same schedule.It doesn't fit you.
Every person forgets at a different pace. Every word does too.
DAYWIKA tracks only the words that slip, building the fewest encounters, the longest memory
into an algorithm that's yours alone.

Custom Algorithm
Quality memory isn't a paid feature.
The algorithm is yours in full, even on Free.
Personalized Examples
Matched to your level and interests.
AI writes the example sentences, just for you.
Certification Mode
Prioritizes exactly what your exam tests.
More certification exams keep arriving.
Deep AI Analytics
Weak points, balance, your best rhythm.
AI reads your learning more deeply.
Up to 3 Languages
Each language, independent.
Each runs on your own algorithm.
Library Converter
Convert your existing lists in the Library,
then add them straight in as custom words.
What makes it different
Every vocabulary app in the world
runs on the same formula.
Same review intervals for every learner. Same rules for every word.
It's the one formula the entire industry shares.
DAYWIKA does the opposite.
It tracks a different forgetting curve for every person, and a different one for every word within that person.
The result: the only algorithm in the world that's entirely yours.
How It Works
An interval built for everyone
fits no one.
DAYWIKA tracks how fast you forget each individual word.
Then, right before it slips away, it brings that word back. Once. At exactly the right moment.
Minimum exposures. Long-term memory.
Even the same word is reviewed at different times for different people.
Words you know well fall back. Only the ones you're losing stay close.
Short-term, mid-term, long-term memory, tracked separately for every word,
all from your own data.
How Your Algorithm Forms
How your own algorithm
takes shape.
It accrues.
Every correct answer, every miss, every response time, logged as data in real time.
It tracks.
Your forgetting curve for each word is calculated individually. No two words are treated the same.
It times it.
Each word comes back right before it fades. Once, at exactly the right moment.
The more you use it, the sharper it gets.
The DAYWIKA engine evolves every day.
All you do is tap Today's Session.
What you study, and when, is the algorithm's call.
Parallel Learning
Three languages at once.
Three algorithms.
Pro lets you study up to three languages at once.
The key word isn't “at once.” It's “independently.”
You forget languages at different rates, so each one runs on its own forgetting curve, entirely separate.
They don't interfere. Your weak spots in Japanese don't crowd out your French reviews.
Analytics
Your memory, growing. All of it.
The algorithm recalibrates your sessions in real time.
None of it is hidden. Every adjustment surfaces as data you can read.
Recalibrates in real time
Your data adjusts every session automatically. Multiple languages each run independently.
Certification Mode
Every word your exam needs.
Made yours.
DAYWIKA prioritizes the exact vocabulary your target exam tests.
Still guided by your own algorithm. More exams are always being added.
Where DAYWIKA Is Headed
Not a word list.
A blueprint for your language brain.
Next up: natural conversation.
And until every learner can study every language, DAYWIKA keeps expanding.
Words You've Built
The more you use it, the more it becomes yours.
Every answer, every response time, every review. Your vocabulary compounds into something entirely yours.
Example dashboard · Based on actual app data
Right before you forget, it resurfaces.
Words that sink don't disappear.
Right before forgetting sets in, at the most efficient moment,
they resurface.
