I Can Follow the Conversation but Forget Every Word I Look Up
You can follow a conversation, read an article with a dictionary open, and understand the word the moment you look it up. A week later it is gone, and the next time it turns up you look it up again. The cause is timing. The words that stop you are the ones you rarely meet, so nothing brings them back before you forget them.

The short answer
Looking a word up gives you its meaning once. Keeping it takes a second and third meeting, spaced out, and the words that stop you are rare ones that seldom return by chance. The fix is something that decides when each word comes back, in material you can follow, instead of leaving it to whatever you read next.

Look it up and keep reading
The default, and it feels like learning. Keep doing it, and expect it to need something added.
You hit a word, look it up, read the meaning and carry on. The lookup does its job: you understood the sentence, and understanding it in the moment is what keeps you reading. Looking words up as you go is sound practice.
The trouble comes afterwards. A lookup is one meeting with the word, and the next one is out of your hands. The words that stop you are the ones a writer or speaker needs seldom, which is why they stopped you, so the gap before the next appearance can be weeks. By then the meaning has gone and you look it up again. Learners call this forgetting. The missing piece is a second meeting soon enough to matter.
Best forStaying in the flow of what you read or hear, as the first step of a routine rather than the whole of it.

Write the words in a notebook or a word list
It puts the word somewhere you can find it. Finding it again is up to you.
A notebook, a notes app or a spreadsheet keeps the word where you can return to it. It costs nothing, needs no setup, and writing the word down is a small extra meeting in itself.
The list helps only if you go back to it, and going back is a chore that competes with the next thing you want to read. Lists grow faster than they get reviewed, and a word sitting alone on a line has lost the sentence that made it make sense.
Best forLearners who want a low-effort record of what they have met, and who will review it on a fixed day each week.

Turn each word into a flashcard (Anki and similar apps)
A scheduler decides when the word returns. You build every card.
A flashcard app hands the timing to a scheduler. The word comes back shortly before you would have forgotten it, then later, then later again. Anki, the app most people use for this, ships FSRS-6, an open-source scheduler built for exactly this problem. If you like the format, this is the strongest answer to the timing problem on this page.
The cost is the card. Each one has to be made, the word, the meaning and a sentence, one at a time, on top of the reading you were doing. That workload is the common reason people stop, and when they stop the queue empties and the words stop returning. A card also meets the word away from any story.
If you keep a deck, keep it. Nothing on this page asks you to give one up.
Best forLearners who already keep a deck, or who do not mind making cards.

TraceSpark, for meeting the words you looked up again inside a story at your level
Capture the word where you met it, then read it again in a narrated story built from your own words.
TraceSpark is built for this one problem. When a word stops you, select it in any app on your phone, a news article, a message, a caption, and choose Capture Trace from the text-selection menu (it can sit under the three-dot menu). You can also share a screenshot with the word circled. Each capture comes back with a translation, a definition written in the language you are learning, a note on register, and a label: vocabulary, phrase, grammar or culture.
Your saved words and phrases are written into the stories you read next: narrated episodes at the level you set, in a series of up to ten episodes planned before the first is written. A second pass checks which of your saved items made it in, so you can see the exact words woven into each chapter. You can read a story, listen to it, or play it with the full script on screen, and generated episodes play with no signal.
The scheduling behind it is FSRS-6, the same open-source scheduler Anki ships. It tracks each saved word and phrase and decides when it is due again, aiming at a 90% chance you still remember it. You grade a word where you meet it, Again, Hard, Good or Easy, from a console at the bottom of the reading screen, without leaving the story. No card is made by hand.
Limits, before you install anything. TraceSpark is Android only, with no iPhone or web version. It has no speaking practice and no correction of anything you say or write. It is meant for learners who can already follow a story at a strong B1 level. It is free to install on Google Play and charges nothing today; paid plans start later.
You can check the writing first: we publish one full generated chapter at each of three levels, printed as the app produced it.
Best forAndroid learners at a strong B1 or above who already look words up in their own reading and want those words to come back.
Frequently Asked Questions
Why do I forget words I look up even though I understood them?+
Understanding a word in the moment and recalling it a week later are different tasks. A lookup gives you the meaning once, and nothing in it decides when you will meet the word again. The words that stop you tend to be rare ones, so left to chance the second meeting comes late. What helps is a second and third meeting, spaced out, in something you can follow.
Do I need flashcards to remember the words I look up?+
You need something that brings each word back. Flashcards do it with a scheduler and manual card-making. A notebook does it if you review it. A story built from your saved words does it by putting the word into a text you read anyway. Pick the one you will keep doing.
Does TraceSpark work for phrases, or only single words?+
Phrases too. Each capture is sorted as vocabulary, a phrase, a grammar pattern or a culture note, and the same capture step handles all four.
Is TraceSpark a replacement for looking words up?+
No. It starts where the lookup ends: it saves the word with a translation and a definition in the language you are learning, then brings the word back in your next stories.
