Read the price, then read the unit
The spread inside this category is wide. Starting lesson prices across the listings run €2 to €1,390, and median lesson prices run €16.47 to €83.31. A starting price is the floor a provider advertises, while a median is the better guide to what most families actually pay, so treat the two figures as different questions.
Read each brand against that span. BUKI lists lessons from PLN 50 and a median of PLN 72 for maths, billed per lesson. ErsteNachhilfe lists lessons from €10.50 with a median of €22.50, and its sessions are set at 45 minutes, so a longer slot changes the hourly arithmetic even when the lesson price looks lower. DojoTutor starts at $10 and publishes no median in the details shown here, which leaves the typical cost open until you request a quote.
Currency matters as much as the number. Two of these brands quote in euros or zloty and one in dollars, so a raw price comparison across brands is not a like-for-like comparison. Normalise to a single currency and to a single session length before you decide anything.
Trial lessons, free tiers and the cost after the trial
Trials are where most price comparisons go wrong. BUKI offers a free trial lesson and charges no service fee on top of the lesson price, so the trial tells you the real ongoing rate. DojoTutor offers a discounted first lesson rather than a free one, so the second invoice is the number that matters. ErsteNachhilfe takes a different route with a free tier, where the free part is a self-serve option rather than a trial with a tutor.
Free trial lengths across the listings run 5 to 28 days, which shows how short these windows usually are. ErsteNachhilfe's paid plan starts at €1.99, and paid plan prices across the listings run €1.99 to €1,401.39, so the step up from a free or discounted start can be steep. Ask what the second and third payments look like before you treat a trial as a price.
Families with more than one child should weigh a specific line: ErsteNachhilfe does not offer a family subscription. That single detail can change the monthly total more than the lesson price does.
Tutor supply and screening
Supply is the next filter. BUKI reports 80,000 tutors, while tutor counts across the listings run 3 to 35,000,000. A wide pool usually means better subject coverage and more evening slots, and it also means screening is the only real quality control you get.
On screening, BUKI states that its tutors are screened. DojoTutor also states that its tutors are screened, and it adds background checks on tutors. ErsteNachhilfe lists its teaching method as live 1to1 but does not list a tutor screening standard in the details shown here, so a family asking about verification has less to go on. BUKI also states a minimum age of 16 in its published terms, which matters for anyone booking on behalf of a younger learner.
Where each brand operates and who is behind it
Coverage differs sharply. BUKI lists its markets as PL, UA and ES, so a family outside that set may be treated as a cross-border customer with different terms. ErsteNachhilfe works in DE and AT. DojoTutor lists a single market, the US, which narrows the practical comparison for readers elsewhere.
Company age is a rough reliability signal. ErsteNachhilfe has operated since 2004, and BUKI since 2014. Behind the brands sit Mriytech Education LTD for BUKI, headquartered in CY, Learn & Care 24 GmbH for ErsteNachhilfe, headquartered in DE, and ClassDojo, Inc. for DojoTutor. Read the BUKI review, the ErsteNachhilfe review and the DojoTutor review before you commit to a booking.
Subjects, session formats and the gaps that decide fit
Subject lists decide whether a brand is a fit at all. BUKI covers math, science and languages. DojoTutor lists math, english and science, which names English as a subject on top of the same school spread. ErsteNachhilfe competes on language range instead, listing German, Arabic and Bulgarian, which is the widest language list among these three.
On session shape, all three offer the same pair of formats, so format does not separate them: 1to1 and group at BUKI, 1to1 and group at DojoTutor, and 1to1 and group at ErsteNachhilfe. What does separate them is what is missing. ErsteNachhilfe has no AI conversation feature, no certificate, no separate version for children and no offline lessons, so a family expecting a completion record or offline practice should look elsewhere or ask directly.
Support, and the order to compare in
Support tells you how quickly a problem gets solved. BUKI offers email, chat and phone, while DojoTutor offers email, help centre and community. Direct phone and chat access matter most when a lesson is scheduled badly or a tutor does not show up, and they are the quickest signal of whether a provider treats support as part of the product.
A workable order for the comparison: price per lesson adjusted for session length and currency, then trial terms and the first paid invoice, then tutor supply and screening, then market coverage, then the feature gaps. Work through that order once per brand, and use the online tutoring rankings to place these three against providers with a similar shape, such as GoStudent and Tutorful. Keep the open questions open: where a brand does not publish a median, a trial length or a screening standard, price the uncertainty into your decision rather than assuming it is low.
