Lectuna for professorsLive classes with real-time captions
The professor teaches in Persian. Every student understands in their own language.
Lectuna transcribes the professor as they speak, captions it in Arabic and English, writes formulas properly, and prepares the session note when class ends. The professor doesn't have to learn anything new.
On iPhone and computers, the full web version is here: classroom.lectuna.ir

General Mathematics 1
Professor's voicePersian
Student caption
The problem isn't the subject. It's the language of the room.
International students in Persian-taught classes are capable and hard-working, yet half their effort goes into decoding sentences. Lectuna is built to solve exactly this.
By the time a sentence is translated, the lecture has moved on
Students have to listen, translate in their heads and take notes at once. The key points get lost in between.
Generic translation breaks technical terms
A "limit" in calculus isn't a "limit" in law. A general translator doesn't know the field and turns spoken formulas into word salad.
Professors can't teach in two languages
Saying everything twice halves the lecture time and isn't fair to the rest of the class.

1
Before class
The class is created with a field and specialisation
That field's glossary is connected to transcription and translation automatically.
Students join with an invite code or link
Each student keeps their own language: Persian, Arabic or English.
Weekly schedule and reminders
An hour before each scheduled session, the professor and students get a notification.
-
2
During class
Live captions in each student's language
The professor speaks Persian or English; each student reads captions in their language and hears the professor too.
Shared board and slides
The professor writes on the board or opens the lecture PDF; everyone sees it live.
Questions without a language barrier
Class group chat and private messages to the professor, each translated into the reader's language.

After class
A smart note for that session
When the professor ends class, a structured note is generated in the student's language, with a title, summary and highlights.
Replay of recorded classes
Audio, board, captions and chat play back in sync, so an absent student sees the whole class.
Assignments with deadlines
Students submit text, photos or PDFs; the professor sees who has submitted and who hasn't.
Built for academic language, not small talk
Classroom captions are only useful if the formulas and terms are right. So every segment of the professor's speech goes through a refinement step before translation.
What was heard
ایکس به توان دو منهای یک، تقسیم بر ایکس منهای یک
What the student sees
(x² − 1) / (x − 1)
Anything with a clear rule (powers, fractions, decimals, limits) is converted to notation by fixed rules, not by model guesswork, so the same sentence is always written the same way.
What was heard
حالا مشتری این تابع رو حساب کنید
What the student sees
Now compute the derivative of this function
Speech recognition sometimes confuses a technical word with a common one ("moshtari", customer, for "moshtagh", derivative). The class's field glossary fixes it before it reaches the student.
The professor says
حدِ تابع وقتی x → 0
Arabic caption
نهايةُ الدالة عندما x → 0
Each field defines a preferred translation for its terms, so "hadd" in maths is always rendered as "al-nihāya" (limit) and stays consistent all term.
Before class, the professor types
Markov chains and the transition matrix
During class
"Transition matrix" and "steady state" come out right, not as similar-sounding words.
Before going live, the professor can choose the teaching language and note the session topic. That single line gives transcription a strong hint.
Inside the app
The student view is in the student's language (Arabic here) and the professor view is in Persian, exactly as they appear in the app.
Students hear the professor, see the board and read captions in their language at the same time. Attendance count and connection quality sit at the top.
When class ends, a paginated note is ready in the student's language, with the session's title, summary and highlights.
Recorded classes replay audio, board, captions and chat in sync. Each recording stays on the server for 30 days.
Every assignment shows its deadline. Students submit text, photos or PDFs.
From one screen the professor starts class, shares the invite code and manages assignments, chats and sessions.
For everyone with a role in the classroom
Universities and faculties
Equal teaching for international students
Without hiring interpreters or adding faculty workload, every session becomes understandable and reviewable for non-Persian speakers.
Lectuna for universitiesStudents
Follow the whole class, with your notes ready
Live captions in your language, a note for every session, questions without language worries, and replays of classes you missed.
Pricing and subscriptionWhat education leaders usually ask
Lectuna is built for real classrooms and students' phones on ordinary internet, not for demos.
-
Verified professor accounts
Professors register with proof of appointment (staff card or a Golestan portal screenshot). No account exists until an administrator approves it.
-
Student privacy
Classmates can't see each other's membership or subscription. In a live class, only the number of attendees is shown, never names.
-
Limited recording retention
Recorded class audio is deleted from the server automatically 30 days after class. Only the professor starts and stops recording.
-
Steady on weak connections
Audio is streamed at a low bitrate, dropped connections reconnect automatically, and network quality is always visible on screen.
-
Classes don't stay open
A live class closes automatically after three hours, with a warning to the professor 15 minutes before; the note is generated right away.
-
Three languages, cleanly
The interface is in Persian, Arabic and English; mixed-direction text and formulas render correctly, and dates follow the Solar Hijri, Hijri or Gregorian calendar.

Frequently asked questions
Does the professor need to learn anything new?
No. The professor creates the class, gives students the invite code and presses Start class at lecture time. Everything else stays the same: talking, the board, the slides.
Which languages are the captions in?
The professor teaches in Persian or English. Captions appear in Arabic and in each user's app language (Persian, Arabic or English).
Do students who know Persian have to pay?
No. Basic membership is free: attending class, hearing the professor, the board, chat and assignment submission. Only translation, notes and replay need a subscription.
What if a student's connection drops?
The app reconnects automatically and earlier captions stay in place. Notes and replays are available after class, so nothing is lost.
How do I buy a subscription?
Message support on Telegram with your account email. After payment, support activates your subscription and it's live the next time you open the app.
Does it work on iPhone?
Yes, through the web version in Safari. Every feature is available on the web, and you can add it to your home screen.
