A Clozemaster alternative is an app that teaches the same vocabulary through connected reading rather than through isolated fill-in-the-blank sentences. Clozemaster takes sentences from a large public corpus, removes one word, orders them by frequency, and has you supply the missing word thousands of times. It is efficient review. What it does not do is give you a reason to care about sentence 1,847, which is the reason most people's Clozemaster streaks end.
What Clozemaster is built for#
Clozemaster presents a sentence in your target language with one word blanked out, plus a translation for reference. You either pick the right word from multiple choices or type it. Sentences are drawn largely from the Tatoeba corpus and grouped into frequency bands, so you can work through the most common 100 words, then the next 500, and so on. Progress is gamified with points, levels, streaks, and leaderboards, and the app tracks each sentence's mastery level so review returns at expanding intervals. It offers listening and reading variants, grammar-focused collections, and a subscription tier alongside a free one. Coverage is unusually broad, including many pairs that no consumer app bothers with.
That combination, huge sentence bank plus frequency ordering plus scheduled review, is genuinely well designed for one job: hammering high-frequency vocabulary into recall.
Why cloze drilling works#
The mechanism is retrieval practice. Roediger and Karpicke (2006) showed that testing yourself on material produces substantially better long-term retention than restudying it, and a cloze blank is a compact test. You cannot recognize your way past it; you have to produce the word. Adding the sentence frame around the blank means you are also practicing collocation and inflection, not just the dictionary form.
Spacing amplifies it. Cepeda and colleagues (2006), reviewing hundreds of experiments, found that distributing practice across time beats massing it, with the optimal gap growing as the target retention interval grows. Any system that reschedules a missed sentence sooner and a mastered one later is exploiting that. We go deeper into the scheduling math in spaced repetition for language learning.
The discovery gap#
Here is the structural limit. A cloze deck is a review system without a source. The sentences arrive from a corpus, in frequency order, with no relationship to each other and no relationship to anything you read, watched, or said this week. Three consequences follow.
First, retention without a hook. Paul Nation's work on vocabulary acquisition (Nation, 2006) emphasizes repeated encounters across varied contexts. A frequency-ordered deck gives you repetition, but the varied contexts are random, so a word never accumulates the web of associations that makes it feel owned rather than memorized.
Second, motivation decays. Sentence 1,847 about a man missing a train is not something you chose. Streak mechanics can carry that for a few weeks, and then most people stop. The apps people keep open are usually the ones attached to content they already wanted.
Third, transfer is untested. Producing a word into a blank is not the same as recognizing it at speed inside a paragraph you are trying to understand. Both matter, and a drill-only diet trains only one.
Reading as the discovery layer#
The fix is not to abandon drilling. It is to put a source in front of it, so the words you drill are words you met somewhere you cared about.
LingoBlend approaches this from the reading side. You paste in text you already want to read, and a percentage of the words are replaced with your target language at a density you set with a slider between 10 and 80 percent. The sentence stays comprehensible because the surrounding language is yours; the target words are the only unknowns. Tap one and you get the meaning plus its grammatical context, tense, person, and base form, and it saves in one tap. This is the diglot weave technique described by Robbins Burling in 1968, and it is explained in full in what is the diglot weave method.
Saved words then feed five practice games on an Anki-style SM-2 schedule, with learning steps at 10 minutes, 1 hour, and 8 hours before graduating to day-scale intervals. One of those games is fill in the blank, built on Tatoeba sentences, the same corpus Clozemaster draws from. The difference is not the drill format. It is that the queue is populated by words you met in your own reading rather than by a global frequency rank.

Who Clozemaster is better for#
Clozemaster is the better tool if you want exactly what it does. If your plan is to grind the top 5,000 words of a language in frequency order, if you already have plenty of input from other sources and need a pure output drill, or if you are studying a pair that smaller apps do not support, Clozemaster is the more direct instrument and nothing here argues otherwise. Its volume is real, its scheduling is sound, and the leaderboard genuinely motivates a certain kind of learner.
It is also the better fit for late intermediates. Once you can already read a paragraph without collapsing, your bottleneck shifts from comprehension to coverage, and high-volume frequency drilling attacks coverage efficiently. The blended-reading model earns its keep further down, when native text is still out of reach and the frequency list feels like a chore with no payoff.
Using both#
The two combine cleanly, and many learners do run both. A practical pattern: read blended text for 15 minutes to meet words in context, then drill for 10 minutes. If you already have a Clozemaster or Anki history, exported word lists can be imported directly; see import Anki decks and word lists for the formats that work.
