Features

Capture. Context. Moments.

These are the three essentials that make Vokabulo the vocabulary coach you always wanted but never knew existed.

Capture

Capture means collecting words effortlessly, right when life happens. Instead of writing a word down to look it up "later" (we know that never happens), Vokabulo translates it instantly so you can stay in the flow.

Example: You’re on your indoor bike watching Netflix and hear a word you want to keep. Open Vokabulo, type it in, and tap Translate. Done.

Context

Vokabulo doesn't just give you a translation; it adds helpful context in both your native and target language. Because let's face it: a word without context stands naked.

Without surrounding words, a single term can mean almost anything. That’s why learning with Vokabulo always means learning with context.

Moments

Moments are curated word sets for real situations—when you want to communicate well and the right words matter. You might be C1 in a language, but still feel stuck when talking about a specific topic.

Need to explain a "scratch on a rental car door" in Marseille? Vokabulo generates a set of relevant words for that exact headache—tailored to your level (A1–C2)—so you walk into that office prepared.

It’s like having a tutor in your pocket who knows exactly what you’re about to face.

Flashcards

Study with swipeable flashcards that adapt to your brain. Words you struggle with return sooner; mastered words step back. You can filter by tags or mastery level, and fit study sessions into your schedule by word count or time.

This logic is built on the scientific Spaced Repetition System (SRS).

Community Sets

Don't just learn alone. Discover vocabulary sets shared by other learners, or contribute your own. Suggest improvements and learn from a living library built by the community.

iPhone and iPad

Vokabulo is a native app, built to feel right at home on your iPhone and iPad. It takes full advantage of the Apple ecosystem. Requires iOS 26 or iPadOS 26. A macOS version is in the works.

Privacy

We don’t store or sell your personal data. We only process what is strictly required to operate the app and handle App Store purchases. Your data is yours. It’s as simple as that.

Getting Started

Your quick guide to setting up Vokabulo.

First things first: Download Vokabulo from the Apple App Store. You can test it for free for 3 days.

Sign in with your Apple or Google ID. It’s the smoothest way in—Face ID handles the security, so there are no codes to type and no passwords to forget.

Prefer to use your email? No problem.

Vokabulo is passwordless. Enter your email address, and we’ll zip a six-digit code to your inbox. Type it in, and you’re in.

One screen for everything: There’s no separate "Sign Up" button. If we recognize your email, we log you in. If you’re new, we automatically create an account for you. Simple.

If this is your first time, you’ll breeze through a quick setup. We just need to know your native language and the one you want to master.

Once your languages are set, you’ll land on the Today screen. It’s quiet now, but let’s change that.

You can fill your library in four ways:

• Browse Community Sets and adopt one that fits your goals
• Enter words manually in Words
• Create vocabulary for specific contexts using Moments
• Import words from another app or file

Vokabulo is packed with power-user shortcuts and hidden gems. Stick around and explore these docs to unlock the full potential.

Today

The Today screen is your home base. It gives you an instant overview of the languages you are learning and your daily progress.

Date slider

At the top of the screen, you'll find the Date Slider. It lets you travel back in time to check your history.

Your Streak at a Glance: Swipe through the days to see your progress build up over time. It’s the easiest way to spot how consistent your learning habit really is.

See an orange number? That’s your daily win. It appears whenever you’ve practiced at least 10 cards on that specific day. Keep those orange numbers coming.

Language cards

Each language card acts as a snapshot of your journey. At a glance, you’ll see:

• Words added today
• Words reviewed
• Your mastery levels
• Your current streak

Switching Languages: Just tap a card to make that language pair active.

The V button

Tap the big Vokabulo V to launch a Quick Study session instantly. It uses the presets from your settings, so you don't have to fiddle with settings every time.

Daily Goal: Review at least 10 words, and the V will turn green to mark your daily goal as complete.

The flag icon

Need to change your proficiency level or adjust settings? Tap the flag icon on any card to jump straight into the settings for that specific language.

Words

Your personal vocabulary headquarters.

This is where you add, edit, tag, search, and review everything you want to learn. We designed this screen to make capturing new vocabulary as effortless as possible.

Whether you’re reading a book, watching a video, listening to a podcast, or exploring an antique market in a foreign city—Vokabulo is ready to capture the moment.

Vokabulo is the fastest way to turn a fleeting thought into a permanent vocabulary card, complete with context and translation.

Enter a new word

Internally, we call it the Magic Wand because, frankly, it feels like magic.

To add a word, tap the plus (+) button in the top right corner. You'll find this on almost every screen, except when you're in the middle of a study session.

Here is the trick: You only need to do half the work. Type or paste a word (or phrase) into any field, and hit Translate. Vokabulo fills in the rest.

Why context matters

A word without context is like a fish out of water—it doesn't survive long in your memory.

That's why Vokabulo insists on learning with context (a phrase or sentence). Context clarifies the meaning, triggers better recall, and ensures you don't just know the word, but know how to use it.

Limits of AI

Vokabulo runs on the latest, most powerful AI language models.

Reality Check: AI is a brilliant co-pilot, but it’s not infallible.

It handles 99% of cases perfectly, but it can occasionally trip over slang, ambiguity, or very rare meanings.

Treat the AI as a capable assistant, not an unquestionable authority. If a translation feels off, trust your gut: refine the context, edit the result, or try again with a clearer prompt.

Pro Tip: Not happy with a translation? Tap the round arrow button next to the green checkmark to re-roll the dice. Tapping it again cycles back to the first result. (Note: Vokabulo has a backup AI model ready to jump in if the main one is taking a nap).

Edit words

Your collection is yours. You can edit entries anytime to tweak translations, fix spelling, or refine the context.

Clean data = better learning. Taking a second to polish a card now means you'll have a much better experience when it pops up in your Flashcards later.

Pronunciation

Vokabulo uses high-quality ElevenLabs voices to make listening and repeating feel natural, not robotic.

Heads up: When you hit “Listen” for the very first time on a new word, it might take a second or two to fetch the audio from the server. After that, it’s instant.

Search & Duplicates

The search bar hunts through words, context fields, and even tags.

Accents optional: Search is smart enough to handle umlauts and accents for you. Type “Madchen,” and we’ll find “Mädchen.”

Vokabulo also keeps an eye out for duplicates. If you try to add a word that’s already in your collection (even in a slightly different form), we’ll flag it so your list stays clean.

Bulk actions

Need to manage a whole list at once? Tap Select to enter bulk mode. You can pick specific items or select all.

This is perfect for:

• Adding tags to a whole group of words.
• Removing tags.
• Cleaning up your list.

Suggest to Set

Found a word that belongs in a Community Set you love? Don't keep it to yourself.

Long-press a word (or use bulk select) and tap "Set" to suggest it to the creator. This helps the community library grow while keeping your personal collection flexible. The set's curator will be notified, and you'll get feedback once they review it.

Using Tags

Tags are the fastest way to turn a chaotic list into a system.

Think of tags as smart folders.

• Find words later: Tag by book, movie, or conversation.
• Study by topic: "Food," "Travel," "Business."
• Stay consistent: Capture everything, sort it later.

Default tags

Going into "binge mode"? You can set a Default Tag in Settings.

This means every new word you capture gets tagged automatically. Perfect for when you're reading a novel or watching a series and want to capture 50 words without tapping "Add Tag" 50 times.

Filter by tags

You can filter your main list by one or multiple tags.

Focus Mode: This makes it easy to review only the vocabulary relevant to what you're doing right now.

Visual Cue: When a filter is active, the filter button turns red. Don't forget to tap "Clear" when you want to see your whole collection again.

Tag management

Power User Move: Long-press an active tag filter to manage it.

From here, you can rename the tag, instantly turn that tag into a Community Set, or delete all words associated with it (great for cleaning up temporary imports).

Sorting

To see your collection in a new light, try switching up the sort order:

• Newest / Oldest: See your journey in order.
• Random: Shake things up.
• Know least / Know best: Focus on your weak spots (or celebrate your wins).

Quick Tip

Wrong language? If you accidentally started typing a French word while your input was set to English, no stress. You can switch the language pair directly inside the add/edit dialog without leaving the screen.

Study

Collecting words is fun, but making them stick is where the magic happens.

Vokabulo uses a smart Spaced Repetition System (SRS). It calculates exactly when you're about to forget a word and serves it up for review at that precise moment.

This means you stop wasting time on words you already know and focus entirely on the ones that need attention.

The No-Cheat Philosophy

Study is not a test. It's training.

There are no points for "winning" a flashcard session, and nobody is watching. Cheating by peeking at the answer only cheats your future self.

The 5 levels

Every word in your collection travels through a journey of 5 levels.

• Got it right? The word levels up and goes on a longer vacation before you see it again.
• Struggled? The word drops down a level and comes back sooner so you can practice it again.

This dynamic system ensures your study load remains sustainable, even as your vocabulary grows.

How to study

You can start a session in two ways, depending on your mood:

• By card count: "I'll do 20 words and then I'm done." (Great for a quick fix).
• By time: "I have 10 minutes on the bus." (Great for time-boxing).

Pro Tip: Tap the big V-icon on the Today page to launch a session instantly using your favorite presets.

Filters & Focus

Want to prep for a specific situation? You can filter your study session by Tags (e.g., "Business," "Travel") or Levels (e.g., "New words only").

Smart History: Vokabulo remembers your last 3 filters, so you can jump back into your routine with one tap.

The Auto button

When studying by "Number of Cards," selecting a tag reveals the Auto button. Tap it to automatically set the session length to match the exact number of due cards in that tag.

The Swipe Mechanics

If you’ve ever used a dating app, you already know how to use Vokabulo.

• Start a session.
• Tap the card to reveal the answer.
• Swipe Right (Got it): "I knew this perfectly."
• Swipe Left (Not yet): "I hesitated or didn't know."

Remember: This is about tracking your personal journey. Swipe left honestly. The app isn't judging you; it's adjusting the algorithm to help you learn faster.

Pause & Edit

Interrupted? Tap the countdown timer at the top to pause your session.

Spotted a typo? If a card looks wrong or the context is confusing, don't just skip it. Long-press the upper text on the card to open the editor right there in the session. Fix it, save it, and keep flowing.

Pronunciation

Building "silent vocabulary" (words you can read but not speak) is a common trap. Avoid it by tapping the Speaker icon to hear the word spoken by our high-quality AI voices.

Troubleshooting: Can't hear anything? Check if your phone is silently connected to your AirPods in the other room!

Display options

You can customize the flashcard experience in Settings (or via the inverse arrow icon during a session):

• Native First: Good for practicing recall (active vocabulary).
• Target First: Good for practicing recognition (passive vocabulary).
• Word vs. Context: Choose whether to see just the word or the full sentence.

The Streak system

Motivation, engineered.

Streaks are powerful, but life happens. Vokabulo’s streak system is designed to reward consistency while protecting you from the frustration of losing everything due to one busy day.

Daily Goal

To keep your streak alive, you must complete at least 10 cards for your active languages before midnight.

Milestone Checkpoints

The safety net.

Most apps reset you to zero if you miss a day. Vokabulo doesn't.

We use Milestones. Once you reach a milestone, it becomes your new "Floor." Even if you break your streak later, you never drop below your highest achieved floor.

The milestones:

• 10 Days (Bronze)
• 50 Days (Silver)
• 100 Days (Gold)
• 200 Days (Platinum)
• 365 Days (Diamond)

Example: You reach a 65-day streak. You have passed the 50-day milestone. If you miss a day, your "Current Run" resets, but your total Streak Level only drops to 50, not 0. When you start again, you build back up from 50.

Streak Languages

You decide which languages count. In Streak Management, toggle the switch for the languages you are seriously studying. Only these will drive your streak and leaderboard position.

Study Days & Pausing

Customize your schedule:

• Weekends off? Disable Saturday and Sunday in settings. The app won't ask for reviews, and your streak stays safe.
• Going on vacation? Use the Pause feature (Indefinite or Scheduled). Your streak freezes exactly where it is until you return.

Reset progress

Need a fresh start? Maybe you took a long break or want to relearn the basics. You can Reset Progress in settings to set all words back to Level 0. (Warning: This cannot be undone!)

Moments

Moments are designed to bridge the gap between "textbook fluent" and "real-life fluent."

What is a Moment?

A Moment is a custom vocabulary playlist generated from a real-life scenario.

Instead of learning random words from a list, you describe what you want to be able to say. Vokabulo generates a focused set of vocabulary that matches that specific context.

It’s the difference between knowing the word for "car" and knowing how to explain "my rental car has a scratch on the bumper."

How to create a Moment

Don't overthink it. Just describe the situation in natural language. Tell Vokabulo who you are talking to, where you are, and what the vibe is.

Pro Tip: Use the microphone. It’s faster, and Vokabulo automatically cleans up your input text. Don't worry about "umms," "ahhs," or not sounding like a BBC presenter—just get your thoughts out.

There is a minimum length for the briefing because context matters: the more specific you are, the better the vocabulary will be. If you cannot press the big button yet, you will need to be more specific.

Need inspiration? On the Moments page, tap the prompts box to see examples of what works well.

Proficiency level

Match your reality. Make sure to select your current proficiency level in the settings.

• If you are A2, Vokabulo will give you safe, essential basics to get you through the conversation.
• If you are C1, it will give you precise, nuanced expressions to help you sound like a native.

Generate & Save

Hit Generate, and give the AI about 30 seconds to work its magic.

Vokabulo usually produces around 25 relevant words (depending on how complex your briefing was).

Review the list, save the result to your collection with a dedicated tag (e.g., #DoctorVisit), and you’re ready to practice it just like any other set.

Tips

• Iterate: You can run the same Moment multiple times with slightly different wording to discover new angles. Tag them all the same way to build a mega-collection.
• Share the Wealth: If you create a Moment that turns out perfect, turn it into a Community Set. Becoming a curator helps other learners navigate the same situations you just mastered.

Community

Don't reinvent the wheel. Learn from the best.

Community Sets are shared vocabulary lists created by people passionate about finding the right words.

Think of them as the ultimate shortcut. Remember those messy "vocabulary lists" people share in forums or Facebook groups? These are the evolution. Structured, searchable, and ready to be added directly to your learning queue with one tap.

Why Community Sets?

Textbooks are great for grammar, but they rarely teach you the specific vocabulary needed for your life - your job, your hobbies, or the specific dialect of the city you're visiting.

Community Sets fill that gap. The goal is simple: Create the best possible list for a specific topic, making it focused, practical, and immediately useful.

A team effort

Community Sets are living documents. They improve over time because people use them, test them, and suggest better translations.

It’s the Wikipedia principle: No single person needs to be perfect. Quality comes from many small improvements by many different eyes. (And yes, contributors get credit. Your @username appears in the credits if you help improve a set).

The Curator

Every set has a Curator (the original creator). Think of them as the Editor-in-Chief.

Curators ensure the set stays consistent and high-quality. They review suggestions and decide what fits, keeping the list focused so it doesn't turn into a random junk drawer of words.

Follow and Auto-Download

When you add a set, you automatically become a Follower.

Want to stay on the bleeding edge? Tap "Notify" to activate Auto-Download. This means whenever the Curator adds a new word, it instantly appears in your personal word list, ready for study.

(To unsubscribe, just tap "Following" again).

Suggesting edits

You can contribute by suggesting new words or fixing existing ones.

Your suggestions are sent directly to the Curator for review. It’s a collaborative loop that keeps Vokabulo accurate and alive.

Safety & Reporting

We want Vokabulo to be a helpful, safe space.

See something wrong? If a set violates our rules (hate speech, spam, etc.), you can flag it immediately.

• Open the set.
• Tap the orange warning sign.
• Select the reason and add details if needed.

You can flag a community set to the admin for violation of the rules. Open the set and tap on the orange warning sign.

The set will be taken offline immediately until our admin team reviews it.

Settings

Make Vokabulo yours.

Tap the arrow icon (top-left) to open Settings. This is your control center for tweaking the engine under the hood.

Languages

Manage the languages you are learning here.

• Current Language Pair: Tap to switch focus.

  Note on Variants: We support specific dialects (e.g., US vs. UK English, Brazilian vs. European Portuguese, Mandarin vs. Cantonese). You select the variant here, but for clarity, the rest of the app just shows the main language name.

• Proficiency Level: Crucial. This tells our AI whether to generate "Tourist Basics" or "Native Nuance" in Moments.
• Language Flag: Choose your icon.

  Reality Check: Flags are complicated. Not every language fits neatly into one country's flag. We suggest a default, but you can swap it for a globe or a different icon if you prefer.

• Data Management: Export your words (backup), import new ones, or reset your learning progress to zero.
• Delete Pair: Warning: This permanently wipes all data for this specific language pair.

Word Defaults

Automate your organization.

Set default tags here that automatically attach to every new word you capture.

Use Case: Reading a novel? Set the book title as a default tag. Now you can capture 50 words without tagging them one by one.

Study

Customize how your flashcards behave.

• Native First: Good for active recall (testing if you know the target word).
• Word Only: Hides the context sentence so you focus on the raw vocabulary.
• Recent Filters: Keeps your last-used tag/level filters active for the next session.

Streak

Protect your progress.

• Pause: Going off the grid? Freeze your streak so you don't lose your hard work while on vacation.
• Study Days: Turn off weekends (or specific weekdays) if you want a streak that only counts study days.
• Streak Languages: Decide which languages count toward your global streak and which are just for fun.

Speech

Your ears deserve the best.

• Speaker Selection: Choose a specific voice or let Auto pick the best one. You can preview them before deciding.
• Speed: Too fast? Slow down the playback speed globally.

We use high-quality ElevenLabs voices. If there's a small delay the first time you hear a word, it’s because we’re fetching that premium audio from the server.
