Grow a language across 91 languages: a personal tutor (text and voice), blind matching with real people, audio rooms, CEFR study plans, a community dictionary and a translator. Educators build lessons fast and export to TikTok, Instagram, and YouTube.
A startup from Lithuanian that is founded by Tomas Vitkauskas.
This page is designed to help you find out whether OwnSlides is good and if it is the right choice for you.
OwnSlides is a language learning platform built around the two things most apps skip: speaking, and being corrected.
Most apps are good at teaching you to recognise words and bad at getting you to produce them. You tap the right tile out of four, then freeze when someone asks you something out loud. OwnSlides is built for that gap.
Practice with feedback
An AI tutor handles conversation by text or voice, adapting to your level and giving grammar corrections and session scorecards. Pronunciation practice records you and scores accuracy, fluency and completeness word by word, so instead of "you're hard to understand" you see exactly which word you mangled. There's also an opt-in mode that roasts your mistakes instead of encouraging you.
Practice with real people
Blind-matched voice calls pair you with other learners for instant conversation practice. Scheduled audio rooms let you join or host group sessions. Audio only, no video, no profile browsing, which keeps it about the language.
Vocabulary that builds itself
Any word you meet anywhere in the app — dictionary, translator, mid-conversation with the tutor, or in the daily games — saves in one tap and comes back through spaced repetition, in flashcard, typing or spoken form. Review timing follows an Anki-style Again/Hard/Good/Easy scheduler.
Structure and habit
91 languages with CEFR-aligned curriculum and study plans, a community dictionary, and a translator. Progress tracking, streaks, weekly leaderboards, and four free daily games (guess the language, guess the city, a pronunciation challenge and an audio spelling bee).
For teachers
Generate a full lesson from a prompt — vocabulary, grammar, exercises — then export it as a narrated video or image slideshow sized for TikTok, Reels and YouTube Shorts. Lessons can stay private and be assigned to specific students with completion and accuracy tracking.
The learner side is free. Credits cover AI generation for teachers building content.

The AI tutor and the live human practice sit in the same app rather than being separate products. You can have a voice conversation with a tutor, get blind-matched with another learner for a call, and review the vocabulary from both in one place. Pronunciation is scored word by word on accuracy, fluency and completeness, so you find out which specific sound you are getting wrong instead of being told you are hard to understand.
Most apps are strong at recognition and weak at production. You can tap the right answer out of four for months and still freeze when someone asks you a question out loud. OwnSlides is built around producing the language and being corrected on it, through spoken practice with both an AI tutor and real people.
Against Duolingo, it does far more with speaking and correction, though Duolingo is better at making you show up daily. Against Anki, the vocabulary system captures words in one tap from wherever you met them rather than needing you to build cards. Against italki, it is cheaper and always available, though a human teacher is still better for real conversation.
Learners who can already read and understand some of their target language but struggle to speak it, roughly A2 to B2. People who have used an app for a while and realised comprehension has outpaced production.
Secondarily, language teachers and tutors who need to produce lesson material and social content quickly, and who want to assign work to their own students and track completion.
It started as a tool for building slide-based educational videos, and the language lessons people made with it turned out to be the part that mattered. The product moved toward language learning from there.
The direction was shaped by a specific frustration: it is easy to build something that tells you whether you picked the right answer, and hard to build something that tells you whether what came out of your mouth was right. Most of the work has gone into the second problem.
