A companion, not a course

Illuminate the language in front of you.

Lantern is a mobile companion for anyone building a life in a second language. Type in the words you actually see—a sign, a text, something someone said—and get a clear, structured explanation. No lessons, no streaks. Just the meaning, when you need it.

The principle

Explain, don’t teach. We answer the German in front of you — and never assign a lesson.

Most apps hand you a curriculum and hope your life fits it. Lantern works the other way around: your life sets the syllabus. The word on the train platform, the phrase in the group chat, the reply at the bakery counter — that’s what you learn, because that’s what you met.

What you get

“Expresses regret — something you now think you should have done.”

What you won’t

“Great job! 🎉 Ready for today’s lesson on the subjunctive mood?!”

01 · Explain

The meaning first, then what’s worth noticing.

Every explanation leads with the natural English meaning, then the grammar that actually matters, in plain language — with the register so you know how it lands.

  • Natural meaning, not a literal word swap
  • Key grammar named and explained simply
  • Follow-ups when you want to go deeper — never before

02 · Ways to Say

Say it the way it’s actually said.

Start from what you mean in English and get real German phrasings — each tagged formal, neutral, or colloquial, so you can match the moment instead of guessing.

You want to say
“I can’t make it tonight.”
Ich muss leider absagen.formal
Ich schaff’s heute nicht.neutral
Ich kann heut’ nicht, sorry.colloquial
03 · Save & Review

Keep what’s worth keeping. Review only what’s due.

Save any word or phrase straight from an explanation. Lantern turns it into spaced-repetition review — both directions, no decks to build, no pile-ups when you skip a day.

  • Lantern suggests what’s worth saving from every explanation
  • Both directions: see German and recall the meaning, see English and produce the German
  • Items retire themselves once you’ve learned them

04 · Situations

Small dares that push you to actually speak.

A Plunge is one specific act of speaking in the wild you could do today — the phrases you need, two fallback lines, and a clear sign it worked. Made to get you past the fear, not to add another lesson.

Bakeryyou could do this today
Order one Brötchen and one Brezel at the bakery.
Einmal Brötchen und einmal Brezel, bitte.
One roll and one pretzel, please.
Können Sie das bitte langsamer sagen?
Recovery — “Could you say that more slowly?”
You’ll know it worked when you walk out holding both.
How it works

03
Keep what matters

Tap to save the words worth remembering. They come back for review exactly when they should.

Why we’re building it
Robin, building Lantern

“I moved to the Allgäu with textbook German and still froze at the bakery. Lantern is the app I wish I’d had — it explains the German in front of you, then gets out of the way.”
