What you taught on Tuesday shouldn't be gone by Friday
Build vocabulary sets from your own lessons and share them with a single link. Your students practise what you chose — not what an algorithm picked.
Sound familiar?
If you teach English, at least one of these is your week.
“I made the wordlist on Sunday evening. Nobody opened it.”
“Four nationalities in one group — and no shared language to translate into.”
“We did these phrasal verbs in March. By June they were gone.”
“Per-student pricing — for thirty students I see once a month?”
You choose the words or phrases in English. And your students practise them.
Most vocabulary apps decide what your students should learn next, and most of them need a translation pair to work at all. Neither helps much in a one-to-one online lesson with a student you don't share a mother tongue with, or in a group where four nationalities sit together.
SAFE works in English. Words are practised through English — definitions, context and examples you write yourself. Whether you teach online or in a classroom, one student or a full group, at home or abroad, the app fits the way you already work.
And whatever came up in your lesson goes into the set: the idioms they stumbled on, the collocations from the article you read together, the phrasal verbs they keep avoiding.
Three steps, about two minutes
Building a set takes less time than writing the homework on a whiteboard.
Build the set
Type or paste the words from your lesson. Add a note wherever a word needs context.
Share the link
Your student opens it in any browser. No account, no password, no download.
They practise
Typing, listening and quiz modes. Their progress stays on their own device.
A new demo is on its way
We're building a new demo together with the new version of SAFE. In it, you'll create your own vocabulary set and quiz — no sign-up, no card, nothing to install.
Built for the way English is actually taught
Six situations where a translation-based vocabulary app quietly stops working.
Online tutors
One-to-one lessons over video, with students anywhere in the world.
Group classes
Mixed-nationality groups with no shared first language between them.
Work and business English
Meetings, interviews, presentations, onboarding — the vocabulary your learners need on Monday morning, whether you teach them one-to-one or run in-company training.
Teachers working abroad
Language centres and schools in Asia, the Americas, Africa, Europe, Australia — anywhere across the continents.
Exam preparation
IELTS, Cambridge and Business English vocabulary, set by set.
Classroom teachers
Homework your students will genuinely do between lessons.
Everything included, nothing to configure
One account, one price, no add-ons to compare.
Pronunciation
Built-in speech for every word, so students hear it as well as read it.
Teacher notes
Add the context your student needs. They can read it, not change it.
Student notes
Your students add their own reminders alongside yours.
Typing and listening
Students recall the word and hear it, not just recognise it on a card.
Quiz mode
Turn any set into an interactive quiz and check what actually stuck.
No student accounts
Nothing for them to sign up for. Nothing for you to protect.
Any device
Phone, tablet or laptop — the same link works everywhere.
Backup and restore
Export your sets as a file and move them between devices.
Who's actually behind this
SAFE is built and run by ORRO GROUP, a small software company in Plzeň, Czech Republic. The person who writes the code is the person who answers your email. There is no support queue in between.
SAFE is also new, and that cuts both ways. You won't find a wall of testimonials on this page yet. But if you tell me something is missing, it can end up in the next version instead of on a roadmap — and the first teachers using SAFE are the ones shaping what it becomes.
Blanka Chudobová — founder, ORRO GROUP a.s.

Questions teachers ask
Does SAFE replace how I teach?
No. SAFE doesn't change the way you teach or replace the methods you already use — you still decide exactly what your students practise, straight from your own lessons. It simply gives you an easy way to prepare vocabulary sets and makes home practice more engaging for students, with a variety of formats to revisit the same words.
Why not just generate vocabulary practice with AI?
You can, and it takes a minute. The question is what happens next: the words end up in a document your student opens once, if at all. SAFE isn't a generator — it's how your words reach your student as a link they'll actually open on their phone, with no account and nothing to install, and come back to. You still choose every word that goes in.
Do I need a credit card to try SAFE?
No. The 14-day trial needs nothing but an email address, and nothing is charged when it ends.
Do my students need accounts?
No. You send a link and they open it in any browser. There is nothing for them to sign up for and nothing to install.
How many students can I use it with?
As many as you like. Pricing is per teacher, not per student.
Can I get SAFE in other languages?
SAFE itself is English-only by design. If you need a version built around a different language, get in touch with ORRO GROUP — we build those.
Do you also develop bilingual apps that allow teachers to teach foreign languages in students' mother tongues?
Yes. ORRO GROUP develops vocabulary-learning apps for any language combination required by language schools, businesses, and individual teachers. Just tell us the languages you need and we'll take it from there.
Where is my data stored?
Your vocabulary sets stay on your own device, not on a server we control, and you can export them to a backup file at any time and move them to another computer. Your students don't create accounts, so there is no student data to look after in the first place. That is deliberate — it keeps you, and any school you work with, out of a lot of paperwork.
Can I cancel?
Any time, from your billing portal. There is no notice period.
Who's behind SAFE?
SAFE is part of a family of educational apps developed by ORRO GROUP a.s. under the ORREG brand.
