Disclosure: German Lens is my Chrome extension. This article was drafted with AI assistance and checked against the published Chrome Web Store description.
When designing a reading helper, there are two different questions to answer: What does this word mean? and Which word form am I looking at?
For German, the second question matters. A reader may recognise the infinitive gehen but encounter ging in an article. A noun translation can also leave them wondering about its gender or plural. A lookup interface that only returns a translated string leaves that work to the reader.
German Lens brings translations and grammar details into a card on the webpage. I recently published it and would welcome feedback from developers who also read or learn German. Below is the interface problem behind it, plus a small test plan you can use for any similar browser tool.
A word lookup has more than one output
A useful way to think about the card is as three layers:
- Meaning: a translation helps the reader understand the sentence.
- Form: an infinitive, noun gender or plural helps connect the encountered word with a dictionary entry.
- Usage: pronunciation and examples help the reader revisit the word later.
The design challenge is deciding what to show first. Displaying every available detail can turn a quick lookup into another reading task. Hiding everything except the translation can remove the information that makes the tool useful for learners.
The right ordering is a usability question: can a reader find the meaning quickly, then find the relevant grammar without searching through unrelated information? That is a more useful feedback target than simply asking whether a card looks nice.
Two interactions to evaluate
German Lens supports selecting a word and using Alt+hover. Selection gives the reader an explicit target. A modifier-key hover interaction offers another way to move through unfamiliar words.
For a browser interface, I would evaluate these separately:
- Does the target match the word the reader intended, especially around punctuation?
- Does the card remain usable near the edge of the viewport?
- Can the reader move between the source sentence and the card without losing their place?
- Is the interaction discoverable from the first use?
These are evaluation questions, not claims that every edge case is already solved. If you try German Lens and encounter a problem, the word, surrounding sentence and interaction used would make the report much more useful.
A small test plan for a language lookup tool
Choose a short German webpage and try a few different cases:
| Case | What to check |
|---|---|
Inflected verb, such as ging
|
Is the connection to gehen clear? |
| Singular and plural noun | Are gender and plural information easy to distinguish? |
| Adjective in a comparative form | Can the reader connect the form to its base adjective? |
| Word next to punctuation | Does selection or hover target the intended word? |
| Word with multiple meanings | Does the reader have enough context to judge the lookup? |
A dictionary result is an aid; the sentence still matters. When a result seems wrong, compare it with the context and another trusted reference.
After the lookup, return to the paragraph and read it again. This checks whether the interface supports the reading task, rather than just whether it successfully displays information.

If you try it, I'd welcome feedback on the card's information order, the Alt+hover interaction and German forms that produce confusing results. A concrete example is especially helpful.

I'd extend the test plan with the same surface word in two contexts: "Die Bank ist geschlossen" and "Wir sitzen auf der Bank." That checks whether the card uses the sentence to distinguish the financial institution from the bench, or clearly presents both senses when it can't choose.
A second useful case is "Er steht früh auf": selecting
stehtalone can hide the separable verbaufstehen. For both selection and Alt+hover, does the card show how much context was used and distinguish a context-based reading from a dictionary list? Keeping that distinction visible in history/export would help learners avoid saving an uncertain sense as a fact. I haven't tried German Lens; these are fixtures suggested by the meaning-versus-form design in the post.
