Hey Product Hunt 👋 I'm Hassan, founder at Vixi.
I kept watching people, like teachers, creators, and coaches, sit on knowledge they wanted to teach, then give up because building an actual course is brutal. Outlines, slides, scripts, quizzes… days of work before anyone learns anything.
So we built Vixi to collapse that into a single step: type a topic, and Vixi generates a complete, interactive, Duolingo-style course with a visual learning map, quizzes, characters, even voiceover — in about a minute.
The part I'm most proud of: it's not an AI text-wall. Learners get a game-like experience with progress, streaks and rewards, so they actually finish.
👉 You can try it right now, no signup: https://vixiai.co
Type any topic you'd teach and watch it build. Then share the course with one link.
We built this as a tiny team and I'll be here all day — I'd genuinely love your feedback, and I want to know: what's the first course you'd generate? Drop it below and I'll react to my favorites. 🙌

Finally tried it with a dense PDF and it actually broke the content into manageable chunks without losing the main points. The Duolingo-style flow makes studying way less painful than just rereading.

@cpham33672 Thaanks! The dense-PDF case is the one we obsessed over, turning a wall of text into something you can actually get through without your eyes glazing. Thank you for giving it a real test, Celeste
— out of curiosity, and if you don't mind, what was the topic of the PDF? Always love hearing what people throw at it...

Would love to see a spaced repetition feature built in so I actually retain what I learn after the initial course finishes, right now I worry it will fade fast.

@rzabzcx This is exactly where our head's at, Rıza. Generating the course is step one, retention is the real game. Spaced repetition is high on our list precisely because we don't want courses to be one-and-done. So yeah smart review of the stuff you're about to forget is the natural next layer. Genuinely appreciate you naming it
Quick one: would you want to have the ability to choose the lessons/concepts of the review, or the course review would cover the entire course after you finish it?

the gamified structure is what would actually get me to finish something for once, my problem with normal course platforms is always dropping off halfway. curious how you handle accuracy on niche or technical topics though - does the model ever just confidently generate a wrong fact into a quiz, and would I have any way to catch that before sharing the course with someone else

@galdayan Honest answer: any AI can state something confidently wrong, so we built two guards. 1- You can ground a course in your own sources (PDFs, docs) to cut hallucination on technical topics.
2- You review/edit every lesson and quiz before sharing. Nothing goes out without your check. Nothing leaves your hands automatically, you're the last check, so you can catch and fix a bad fact before you send it to anyone. You can even add new lessons/conversations to your course that the AI did not generate. So, the course content is fully editable before and even after publishing your course.

@hassan_alzahabi that review step makes sense, my real worry is more about the source-grounded case specifically - if I upload a dense technical PDF, does the tool flag which parts of a quiz answer came straight from my source vs which parts it filled in on its own, or does it all read the same and I'm stuck fact-checking the whole thing line by line anyway

@galdayan Two parts. On coverage: we built the generation so no section of your PDF gets skipped, every part maps to a lesson. We tested this on multiple full books and long PDFs we had read cover-to-cover before feeding them in, then checked the generated course to confirm everything was actually covered. So the "did it quietly drop half my source" worry is the exact thing we hardened against.
On your specific question, inline "this line came from your source vs the model filled it in" flagging, currently it doesn't visually mark that yet; it reads as one course. Grounding + full coverage cuts the risk a lot, but answer-level source attribution is a great trust feature we want to add.
Report
@hassan_alzahabi fair enough, and honestly full coverage + grounding already solves the bigger risk which is content silently missing. answer-level attribution can come later as a nice-to-have. good luck with the launch
the share-by-one-link part is what stands out to me more than the generation speed, most course builders trap everything behind an account wall for the person receiving it. does the shared link stay fully interactive (quizzes, progress tracking) for whoever you send it to, or is it more of a read-only preview once it leaves your own session

@omri_ben_shoham1 You've put your finger on the thing we cared about most, Omri.
It's not a read-only preview, the shared link is the real, fully interactive course: quizzes, the game-like flow, all of it works for whoever you send it to. The one honest nuance: the very first lesson is fully playable with zero signup (so no account wall to just experience it), and the moment someone wants their progress, streaks, and completion saved as their own, they create a free account, because progress tracking is tied to their learner profile, not yours.
So: no account wall to try it, a free account to keep their progress.

Hassan, turning a pile of my own reading into something that feels like a little game to play through sounds honestly delightful. Learning sticks so much better once it stops feeling like a chore.

@joan_live Thanks! That's exactly the feeling we were chasing, Joan. "Learning stops feeling like a chore" is basically the whole reason Vixi exists.
