Lingua for Tutors
Run your language-tutoring practice on a single platform: 60-language curriculum, branded booking page, one-tap video, Stripe Connect with 0% Koydo cut, parent-share with audio of your student reading aloud, and the built-in AI tutor for daily drills between your lessons. $19 a month flat, open from your first student upward, 14 days free with no credit card. italki, Preply, Cambly, and Wyzant take 15-33% of every lesson forever. Koydo takes a fixed software fee and never touches what your students pay you.
The toolkit is the same. The teaching reality is yours to pick.
Online tutors
Mostly Zoom, mostly adult students, mostly your own roster you've built over years. Leaving italki / Preply / Cambly is the big question. Break-even math, a CSV importer to bring your roster across, your own branded subdomain, the full payment story — it's all on the dedicated page.

Mostly in-home, mostly K-12 students, mostly intermittent kitchen WiFi. Offline iPad mode, photo-of-homework capture, parent share-link with audio, $19/mo flat from your first student — all on the dedicated page.
Read the traveling-tutor page →Most tutors do both. The same $19/mo Pro Educator account handles in-home and online lessons on one login.
Eight things you stop paying for separately.
CEFR-graded units from A1 to C1. Vocabulary banks, conversation scenarios, pronunciation tracking, music lessons with karaoke alignment. Replaces Quizlet, Anki, Quizizz, and the patchwork of Google Docs most tutors hold together.
your-name.lingua.koydo.app — students self-book on your availability windows. Timezone-aware. Calendar sync with Google, iCloud, and Outlook. Replaces Calendly Teams at $12 per seat per month.
Built into every scheduled lesson. Browser-only, no install. Recording, screen-share, captions. Replaces Zoom Pro at $15 per month.
Students pay you through your booking page. Stripe's 2.9% + 30¢ passes through; Koydo takes nothing. Optional Koydo Payments tier is 5.9% + 30¢ all-in if you want statements, 1099 prep, and a rolling chargeback reserve handled.
Every under-13 student account requires verified parental consent before any audio or transcript is stored. Inherited from Koydo's Sprouts/Junior/Kids age tiers — battle-tested on tens of thousands of K-8 accounts.
After each session, parents get a tutor-branded link with their child's reading-aloud audio, error rate, mastered phrase count, and time-on-task. No app install required for the parent.
Students drill between your sessions on the included AI tutor — vocabulary, basic conversation, pronunciation feedback, grammar corrections. You set the topics; the AI runs the reps. Premium AI (Claude Sonnet 4.6) optional at +$15/mo for advanced C1/C2 work.
Every student carries a persistent progress record across in-home, online, and AI-drill sessions. CSV export at any time — no data lock-in.
Flat, published, no quote calls.

Full payment math:How tutors get paid.
The job of teaching is the job. Everything else is overhead.
A typical independent language tutor in 2026 holds together six subscriptions to do one job: a marketplace (italki or Preply) for student discovery, Zoom Pro for the video room, Calendly Teams for the booking page, Quizlet or Anki for flashcards, Google Docs for lesson plans, and Venmo or Stripe for payments. The math adds up to $60-$120 a month in software plus a 15-33% commission tax on every lesson. The marketplace tax alone, for a tutor billing $1,600 a month, runs $240-$525 every month, every month, forever.
Koydo Lingua collapses the stack into one $19 SaaS bill with 0% Koydo cut on student payments. The 60-language curriculum replaces the flashcard apps and the lesson-plan docs. The branded booking page replaces Calendly. LiveKit video replaces Zoom. Stripe Connect Express replaces the patchwork of Venmo, Cash App, and bank transfers most tutors awkwardly juggle. The parent share-link with audio of the child reading aloud is the thing parents have been asking for since the iPad existed and no marketplace ships. The built-in COPPA parental-consent flow handles the under-13 paperwork that most independent tutors honestly never wired up correctly. A tutor moves to Koydo not because they hate the marketplace — they move because the toolkit is finally one piece of glass.
The fair trade is that Koydo does not send you students. The platform is software, not a marketplace. Your students come from the place they always came from — word of mouth, your own social following, school referrals, parents at your own children's school, a previous italki roster you can email directly. If you have zero students and zero network today, the marketplace is the right first step; come to Koydo when you have repeat regulars and the marketplace commission has become a $300+/month problem. Most tutors hit that threshold around hour 6-8 of weekly teaching.
Pro Educator is open from your first student upward — there is no minimum-student threshold, no quote call, no sales pitch. Sign up for the 14-day free trial without a credit card, import your existing roster from italki or Preply via the included CSV importer, hand out your branded booking link, and run the next week's lessons on Koydo. If it does not work, walk away — the gradebook exports as CSV, the student records export as JSON. No data lock-in.
/tutors is the short overview page. If you teach mostly over video, the deep page is /for-online-tutors. If you drive to students' homes, the deep page is /for-traveling-tutors. Most tutors do both — the same $19/mo Pro Educator account handles both modes with one login, one curriculum, one gradebook.
Pro Educator covers unlimited students at a flat $19 a month. You get the full 60-language Lingua curriculum (CEFR-graded units, vocabulary banks, conversation scenarios, music with karaoke alignment), the built-in GPT-4o-mini AI tutor for daily drills, your branded booking page (your-name.lingua.koydo.app), LiveKit one-tap video, Stripe Connect Express with 0% Koydo cut on student payments, the parent share-link with audio of the child reading aloud, the built-in COPPA parental-consent flow for under-13 students, and the cross-session gradebook. Premium AI (Claude Sonnet 4.6 / GPT-5 tier) is an optional +$15/mo add-on.
Yes. Pro Educator is open to any tutor from your first student upward — 14 days free, no credit card. There is no minimum-student threshold. The flat $19/mo holds whether you teach 1 student or 100.
Those are marketplaces that send you students in exchange for a recurring commission tax. italki takes 15-21% per lesson, Preply takes 18-33%, Cambly pays roughly 41 cents on the dollar, Wyzant takes 25%. Koydo Lingua is software, not a marketplace — you bring your own students (or grow them from your own network), and Koydo never touches what they pay you. A tutor billing $1,600 a month saves $250-$540 every month by switching, every month, forever. The trade-off: Koydo does not send you students. If your only acquisition channel is the marketplace inbox, stay there. If your students already know your name, leave.
Koydo charges 0% of student payments. Stripe's standard 2.9% + 30¢ payment-processing fee passes through to your Stripe Connect Express account — you would have paid that on any other platform. The optional Koydo Payments tier is 5.9% + 30¢ all-in (2.9% + 30¢ Stripe pass-through, 2% Koydo operational margin, 1% rolling chargeback reserve reconciled annually); use it when you want Koydo to handle 1099 prep, dispute coordination, and the rolling reserve instead of carrying that overhead yourself. Most tutors start on direct Stripe and only graduate to Koydo Payments after a single bad chargeback teaches them the value of the reserve. Full plain-English math at /how-tutors-get-paid.
Koydo Lingua ships a built-in COPPA parental-consent flow inherited from Koydo's Sprouts (ages 2-5), Junior (5-8), and Kids (8-11) age tiers. Every under-13 student account requires verified parental consent before any audio or transcript is stored. Parents get a tutor-branded share-link with their child's reading-aloud audio, error rate, and mastered phrase count after each session. No third-party tracking pixels run on student-facing pages.
Most tutors bring students they already have — from word of mouth, a personal Instagram or TikTok following, school referrals, parents at their own children's school, community-class spillover, or a previous italki / Preply roster they can email directly (most marketplace terms allow tutors to communicate off-platform with established clients). Koydo's /find-a-tutor public directory is a free supplemental listing for verified Pro Educator tutors who opt in. It is not your primary acquisition channel — your network is. The platform exists so that once a student is yours, they stay yours.
Yes. Stripe Connect Express is supported in 40+ countries; payouts go to your local bank in 1-2 business days. Lingua's $19/mo SaaS fee is subject to standard SaaS VAT in the EU and is added at checkout. UK, Canada, Australia, New Zealand, Singapore, Japan, and most of the EU get full parity with US tutors on every workflow except the US-specific 1099-K (non-US tutors get a year-end income summary suitable for their local tax filing).
Both deep pages share the same $19/mo Pro Educator. Pick the one that matches how you mostly teach.
