Built by one person, in public.
RYUN isn't a company with a partnerships team; it's three tools built and maintained by one developer, , currently in open beta. I'm building it because I kept watching students (myself included) pay for three or four separate $15–30/month subscriptions to do things that don't need a subscription: find a quiet desk, actually learn a language, and not get filtered out by an ATS. RYUN connects your own AI account instead, so you pay the AI provider directly and the tools stay free.
What's actually live today
- Study Hush: crowdsourced decibel readings and a campus study-spot map, installable as a PWA
- Nativra: language learning from real YouTube videos and subtitle files, with SM-2 spaced repetition and Anki export
- Ravina: a deterministic 13-point ATS resume check and STAR interview coach that work offline, no API key required for the free core
- One account for Ravina and Nativra, 100% free of use with BYOK architecture (connect your own AI provider account at 0% markup)
Being honest about the beta
This is a real, working product, not a mockup, but it's also one person's beta, not a funded startup with a support team. If something breaks, is confusing, or you just want to ask a question, contact me directly, and you'll hear back from the person who actually built it.
Who writes the guides
Every guide, comparison, and blog post on this site is written by me, Ali Hosseini, and carries a visible publish and update date. I write about applicant tracking systems, behavioral interviews, and learning languages from video because those are the problems the tools solve, and I'd rather explain how they actually work than tell you the tools are the best. Comparisons say where the alternative wins. Recent posts (latest: Brain.fm and Endel Alternatives: Free Procedural Soundscapes for Focus Without a Subscription).
