Why Komivo Vocab
Looking it up isn’t enough — keep going until it sticks.
Common lookup habits leave gaps. Vocab closes them in one flow.
- The usual gapWith Vocab
Clear now. Gone later.
Checking a meaning once often isn’t enough to recall it next time.
Check retention with Review and Test
In Review, practice recalling with your saved examples. In Test, check retention with new problems generated from what you learned.
Word lists drop the context.
Keeping only the word makes it easy to forget where and how it was used.
Keep the encounter context
Save the word with the sentence and situation where you met it.
Card-making friction stops review.
Gathering meaning and examples by hand is often what stops learning.
Make card creation lighter
Meaning, translation, example, and audio created together — so you spend time remembering.
Use cases
You meet words in more than one place.
Start from wherever the word shows up — reading, work, study, or media.
Articles and news
Save a word with the article sentence that made it matter.
Exam reading passages
Keep hard words with the context that made them hard.
Work docs and email
Save workplace expressions you need to recall later.
University and graduate readings
Organize denser language without losing the original context.
Videos and podcasts
Turn noticed expressions into cards you can review.
Dictionaries, ChatGPT, or a single word
After you understand it, keep a form you can review — or start from the word alone.
