New · for the curious reader

Every word
you meet,
kept.

Wordnest quietly keeps every word you read — share or look one up and it lands in your nest — then asks you to use it, and tells you, kindly, whether you really got the meaning.

The Lexicon: your collection of kept words, searchable and filtered by mastery
Today's words: the word of the day, chosen a step above your level

Kept automatically

Look up a word and it lands in your collection. No bookmarking, no folders — just a nest that fills as you read.

Yours to shape

Browse, search, and swipe away the ones you no longer need. Your shelf holds only the words you actually want.

Learn on purpose

Guided courses build on the words you know — a step above your level — so your vocabulary grows deliberately, not just by chance.

Proven, not memorized

Write a sentence with the word. A patient tutor tells you whether the meaning truly landed.

A comprehension check: Wren grades your sentence for the word liminal and explains why
The comprehension check

Knowing a word and
using one are different.

Tap any saved word and write your own sentence. Wren, your tutor, grades it three ways — and explains the why in a single, kind line.

You've got it
Spot-on — the meaning lands.
?
Almost there
One small slip — a hint, not a scolding.
!
Not quite
It means something else — here's how.

I finally remember the words I look up instead of losing them in a Notes file. The “almost” nudge is weirdly satisfying.

It's the only vocabulary app that feels quiet. No streak guilt — just my own collection slowly growing.
