The idea
Not a dictionary.
Not flashcards.
A coach.
Most vocabulary apps show you a word and a definition. That tells you what a word means. It does not tell you when or why to use it — and it will not make you reach for it in a conversation three days later.
Vernac is built around a different premise: context is more powerful than definition. If a word arrives with an example that fits your actual life — your job, your interests, your goals — it has somewhere to land in your memory.
The AI generates that context for every word, for every user, individually. The lawyer and the designer see the same word, but in entirely different sentences.
How it works
Three steps. One habit.
1
Tell Vernac who you are
Your job, your interests, your goals. Five quick questions during onboarding is all it takes to build your first word queue.
2
Swipe through your daily words
Swipe right on words you know, left on ones you want to learn. Five words per session, twice a day. Done in under a minute.
3
Words come back when you need them
Spaced repetition surfaces words at the exact intervals proven to move them into long-term memory. No effort required.
Features
Everything you need to build a real habit.
01
Personalized feed
A swipeable word feed that adapts to your job, interests, and vocabulary level. Every word is chosen for you — not a generic list.
02
AI-written context
Each word arrives with an example sentence written for your world. If you work in law, the example is in a courtroom. If you're a designer, it's in a brief.
03
Spaced repetition
Words return at scientifically timed intervals using the SM-2 algorithm. You won't just see a word — you'll own it.
04
Ambient learning
Home screen widgets and lock screen wallpapers put words in front of you without opening the app. The best session is the one that happens passively.
05
Practice modes
Meaning match, fill-in-the-gap, AI-graded sentence writing, pronunciation challenge, and timed speed rounds. Every mode reinforces differently.
06
Vocabulary level test
30 adaptive questions that estimate your vocabulary size, place you on a five-level scale, and surface exactly where to focus next.
Who it's for
Built for anyone who cares about words.
Professionals
Sound sharper in meetings, write more precisely in emails, and command a room with language that lands.
Students
GRE, SAT, IELTS, TOEFL — Vernac has dedicated word banks for every major test, delivered in your daily feed.
Word lovers
Beautiful words, untranslatable gems, vivid expressions. Vernac has 23 categories for every kind of obsession.
Design
Typography is the design.
No illustrations, no photography, no decorative color. The word on screen — large in Poppins SemiBold on near-black — is the entire visual experience. Color draws the eye away from content. In an app where the content is the product, color is a liability.
Six monochromatic themes let you choose the tone that suits you. The word always dominates, regardless of theme.
