Who it's for

You understand almost everything. It's the “almost” that gets you.

dailyBe is for people who are past the beginner stage, understand 60% to 70% of an English sentence, and want the rest.

  • Shows and movies

    You follow the plot, but you miss parts of the dialogue, even with subtitles on.

  • At work

    When a meeting picks up speed, you're never quite sure you caught everything.

  • When you speak

    You study, you recognize the word when you read it, and then it's gone the moment you need it.

It all comes down to one thing:not enough practice with new vocabulary.

The missing words

Stop pretending you understood.

If you know “I'm busy.” but not “I'm swamped with meetings.”, you need to learn what's missing… not more of the same.

Beginner apps keep drilling what you already know, and it feels like progress. What actually holds you back are the words between basic and fluent: the ones in shows, meetings and podcasts. That's where dailyBe does its work.

How that sentence reaches you today

Sorry, I'm (a word you don't recognize) with meetings today. Can we (a word you don't recognize) tomorrow?

“I kind of got it…”

Once you've learned what's missing

Sorry, I'm swamped (buried in work) with meetings today. Can we touch base (check in briefly) tomorrow?

“I understand everything perfectly!”

How it works

Discover, practice, remember.

The dictionary, the practice and the reviews all live in one app. You choose what to learn; dailyBe decides when to review it.

  1. dailyBe dictionary (in Portuguese) for the word walkthrough: translation, definition and example sentences, each with a Learn button

    Discovery

    Look up the word you don't know

    The AI dictionary takes words, expressions and phrasal verbs, and shows at least 5 example sentences in different contexts. Add the ones you want to learn to your list.

  2. dailyBe exercise: put “Please summarize the main points quickly.” into Portuguese by tapping words

    Practice

    Practice by speaking, seeing and listening

    Sessions of 10 sentences from your list, in three modes. In speaking mode, the app shows what it heard and, if you got it wrong, gives you a pronunciation tip.

  3. Chart of the effect of reviews (in Portuguese): without reviews, recall drops close to zero; with spaced reviews, it jumps back up after each one

    Retention

    Review at the right time

    Get it right and the sentence comes back later: tomorrow, then in 3, 5, 7, 14, 28 and 54 days. Miss it and it drops back a step and returns sooner. That's spaced repetition moving vocabulary into long-term memory.

Features

Built for people who want to understand everything

Every feature is there to help you learn the words you're missing, keep them, and keep studying.

  • Discovery

    AI-powered dictionary

    Look up words, expressions and phrasal verbs and get at least 5 example sentences, in different contexts, to choose what to learn.

  • Pronunciation

    Speaking mode with pronunciation tips

    Say the sentence and the app shows what it heard. Got it wrong? You get a tip spelled the way a Brazilian would read it: “I should have known better” becomes “ai xúdav nôun bérer”.

  • Vocabulary

    Stories

    Short stories of 30 sentences each to grow your vocabulary. A good fit if you're closer to the start.

  • Consistency

    Goals, streaks and friends

    Pick a daily goal, keep your streak going, and compete with friends on study time over the week and the month.

  • Progress

    Learning tracked word by word

    The app counts how often you get each word right. Get it right enough and the word counts as learned; once every word in a sentence is learned, the app moves the next ones up.

    “Your progress on this sentence” screen: each word of “The book is on the table” marked Learned or Learning

No shortcuts

This isn't a 5-minute app.

dailyBe is real study: a few sessions a day, adding up to 20 to 30 minutes of full attention. If you want a quick game to play between other things, there are plenty of apps for that. If you want to understand everything you read, hear and watch in English, this is where the work gets done.

5 min20–30 mina day, fully focused

It's for you if…

  • You understand 60% to 70% of an English sentence and want the rest.
  • You read, listen to or watch things in English and feel you're missing details.
  • You take classes and want something extra focused on vocabulary.
  • You're up for 20 to 30 minutes of focused study a day.

It's not for you if…

  • You're starting English from scratch.
  • You're looking for something to tap through in 5 minutes on autopilot.
  • You expect to be fluent in a few days.

FAQ

See all questions

Is dailyBe for beginners?

No. dailyBe is for people past the beginner stage, who understand 60% to 70% of an English sentence and want the rest. Stories help if you're closer to the start, but if you're starting from scratch, it isn't the right app yet.

How long does a session take?

Each session has 10 sentences. Experienced learners finish in 4 to 5 minutes; if you're just starting out, it can take up to about 25. You can do as many sessions as you like while there are sentences to study, and you set your own daily goal. What works is serious study: a few sessions a day, 20 to 30 minutes in total, with your full attention.

Is dailyBe free?

You can use dailyBe for free. Free use comes with a daily limit on dictionary lookups. A subscription raises that limit tenfold and gives you early access to new features.

How does the app decide when to review a sentence?

With spaced repetition. Each right answer pushes the next review further out: tomorrow, then in 3, 5, 7, 14, 28 and 54 days. Each miss drops the sentence back a step so it returns sooner. The app also tracks every word: once all the words in a sentence are learned, it moves the next sentences up.

Where do the example sentences come from?

They're generated by AI. If you spot a pronunciation or translation error, you can report the sentence right in the app and it goes to human review.

Does it replace my English classes?

It doesn't have to. dailyBe works alongside your classes: while your course follows its curriculum, you train the words your English is missing.

Does dailyBe teach other languages?

Right now, only English. German, Spanish, Italian and French are planned for the future.
