Criterion by criterion
What each row of the table means in practice — and why.
Cost for 20+ people
A traditional teacher charges by the hour — with 20–30 people the cost rises linearly and quickly becomes the largest item in the training budget. Free apps are tempting because they cost nothing, but "free" gets you a consumer product with no oversight and no measurable outcome — the real cost is your employees' wasted time. A platform is a predictable subscription per user, and the cost per person falls as the team grows.
Business and industry language
Free apps teach general language (travel, everyday life) — not what an employee needs on a call with a client. With a teacher, the level of industry vocabulary depends on the individual and varies. A platform gives you ready-made specialist modules (IT, cyber security, finance and HR among others) plus Business English — consistent across the whole team, whoever is leading it.
Progress reports for HR
This is the Achilles heel of free apps — HR has no visibility at all of who is learning and how much. A teacher can report back, but the report is manual, subjective and time-consuming. A platform gives you a dashboard of activity and progress in real time — the data you need to account for the budget and show the board a concrete result.
Sustaining engagement
The hardest part of any training programme. Apps have gamification, but without a company context attendance usually drops off after a few weeks. A teacher enforces discipline through the fixed slot, but one lesson a week leaves little practice in between. A platform combines short formats (5 min), gamification and a leaderboard with activity monitoring — HR can see it before someone drops out, and step in while there is still time.
Speaking practice
Honestly: live conversation with a teacher is the best there is — immediate correction and response. Free apps offer almost no speaking at all. A platform makes up for it with the AI Tutor (voice chat) 24/7 — practising what you want to say without pressure and without a timetable; it will not replace a human 100%, but it gives many times more repetitions between lessons.
Scheduling flexibility
A teacher means fixed slots, which clash with meetings and business trips. An app and a platform let you learn at any time — on the commute, during a break, in the evening. A platform also builds a personalised path (AI Roadmap), so those 5 minutes are well spent.
Rollout in the company
Getting lessons with a teacher off the ground is a project: levels, groups, rooms or links, timetables. Apps have no company process — everyone signs up on their own, with no oversight. A platform is rolled out in 1–2 days: employees log in with their work email, no IT involvement needed, and HR gets the dashboard straight away.
Polish-based support, invoice, GDPR
Global apps mean no Polish-language support, no invoice and no data processing agreement — in a B2B purchase that is a genuine obstacle. A teacher or a school in Poland handles this as a matter of course. So does the platform: the operator is PROLANG Sp. z o.o. — Polish-based support, an invoice and a GDPR/DPA agreement on request.
What this means in practice
VOCAbite vs free apps
Duolingo and Memrise are excellent for learning on your own, but they are consumer products. In a company they lack what matters to HR: progress reporting, industry vocabulary, a company rollout, an invoice and a data processing agreement. Nor is there any way to prove the training worked to your board.
Choose an app when: someone is learning alone, as a hobby.Platform vs a traditional teacher
A teacher gives you live conversation and correction on the spot — that is their advantage. But with a larger number of employees it becomes expensive and the timetables are hard to organise. A platform is cheaper at scale, available 24/7 and measurable. That is why a blended model usually works best.
Choose a teacher when: intensive 1:1 conversation is the priority.The best of both worlds: a blended model
VOCAbite is backed by a real language school — Prolang, established 2002. The platform takes on daily practice and vocabulary retention (AI Tutor, VOCAbox, short formats), and wherever live conversation is needed we add lessons with a teacher. Your team learns consistently, and you get a measurable result and a single point of contact.
