For language learners, classrooms and departments

The problem isn't AI.
It's which AI.

Students will use AI either way. Explica is the one that explains instead of doing the work. Highlight any word or sentence anywhere in your browser and get a real explanation — in the language you're reading, pitched at your level — instead of bouncing out to a translator and losing the thread.

Works on any website · Google Docs add-on included · 7 days free, no card

A translation ends the sentence. An explanation opens it.

A student stuck on a paragraph pastes it into a chatbot and gets a finished English translation. They move on having learned nothing, and you can't tell from the homework.

General chatbot

  • Returns a finished translation
  • Writes the essay when asked
  • Invisible to the teacher
  • Reading practice skipped entirely

Explica

  • Explains in the target language
  • Gives hints and patterns, never the answer
  • Teachers see engagement per student
  • Level floor set by the teacher, not the student

How it works

1

Read anything

News, articles, assigned readings, Google Docs. Highlight a word or a sentence anywhere in the browser.

2

Get taught, not told

Meaning, grammar, structure, register and synonyms — written in the language being learned, pitched at the student's level. Ask follow-ups if it's still unclear.

3

Write with a coach

Stuck writing? It offers vocabulary and sentence patterns — never a paragraph to copy. Large pastes are flagged.

Built for how languages are actually taught

Explanations in the target language

The whole point. Four levels, from full support in the student's own language to strict target-language-only.

Teachers set the floor

Require Advanced in your class and students can't quietly switch to getting everything in English. Enforced server-side, per class.

Automatic language detection

Highlight German on one tab and Spanish on the next. Nothing to configure per site.

Writing that stays theirs

Hints, patterns and questions — never a rewrite. Works in the extension and inside Google Docs.

Real visibility

Per-student lookups, most-searched vocabulary, engagement levels, and assignment progress.

Integrity signals

Large pastes into assignments are recorded and shown to the teacher, with the pasted text highlighted in the submission.

…die Bundesregierung bei der Rente noch die Kurve kriegen würde.

In this context

Umgangssprachlich: sich im letzten Moment noch korrigieren oder retten.

For anyone reading in a second language

You don't need to be in a class. If you read news, research, contracts or fiction in a language you're still building, Explica keeps you in the text.

  • Reading a foreign-language source for work or a degree, and can't afford to skim past what you don't know
  • Living abroad and dealing with letters, forms and news in a language you're still learning
  • Studying alone and want explanations that build the language, not replace it
  • Comfortable enough to read, but losing the nuance — register, idiom, why it's phrased that way

For teachers

Create a class, share a six-character code, and you're running.

  • See which students are actually reading, and which words they get stuck on
  • Set assignments students complete inside Explica, so the writing is observable
  • Group classes by term and archive them at the end of the year
  • Set the minimum level per class

How we verify schools

A domain claim grants nothing until ownership is proven:

  1. You must sign in with an address at the domain you're claiming.
  2. You publish a DNS TXT record we give you — only whoever controls the domain can do this.
  3. Or we verify you directly, by confirming you represent the institution.

Languages included

Every plan includes all of them — students switch freely, and a class can be set in any one.

🇪🇸 Spanish 🇫🇷 French 🇩🇪 German 🇮🇹 Italian 🇵🇹 Portuguese 🇳🇱 Dutch 🇸🇪 Swedish 🇵🇱 Polish 🇷🇺 Russian 🇹🇷 Turkish 🇬🇷 Greek 🇸🇦 Arabic 🇮🇱 Hebrew 🇮🇳 Hindi 🇨🇳 Mandarin Chinese 🇯🇵 Japanese 🇰🇷 Korean 🇺🇦 Ukrainian 🏛️ Latin 🇬🇧 English

Explanations are written in the language being learned, at the level the student is set to.
