What's the best online platform for teaching English to kids?

The short answer: for teaching English to kids online, the best platform is the one that keeps a young learner engaged for a full lesson without a stack of bolt-ons. That rules out a generic video call almost every time — kids on Zoom or Google Meet check out fast when the lesson is mostly talking heads. It rules in a purpose-built virtual classroom for young learners, where the teaching surface, the drawing tools, the rewards, and the parent-facing side of the lesson live in the same browser tab as the video. Koala Go is the platform we build for exactly this shape of tutor, and it has a free plan good enough to run real lessons on — but the honest answer is that any purpose-built kids' tutoring platform will beat a video-first tool for this audience. Below: how the three real options compare, what actually matters in a lesson with a seven-year-old, and how to pick without spending a month trialling tools instead of teaching.

The three real options for online kids' English

Everything on the market for teaching English to children online falls into one of three shapes. Pick the shape first; pick the vendor second.

1. A general video tool (Zoom, Google Meet, or a Skype-successor). Ubiquitous, free for short calls, and parents already have them installed. But they are designed for adult business meetings, not for holding a seven-year-old's attention through phonics practice. Out of the box you get a video window, a screen-share button and, at most, a basic built-in whiteboard. What you don't get: a drag-and-drop activity the student can drive, a sticker chart or reward system, or a scheduling and invoicing side. You'll bolt those on — Google Slides, a separate whiteboard tab, Calendly, a payments tool, a paper reward chart — and pay the switching cost in stack-juggling every lesson. Google's Jamboard, the whiteboard companion most Meet-using tutors relied on, was retired at the end of 2024, which made the "Meet + Jamboard" default worse.

2. A marketplace platform (Outschool, Preply, italki, Cambly, and similar). These solve the hardest problem — finding students — by matching parents to tutors on their site, and they give you a browser-based classroom to teach in. The tradeoff is that the marketplace owns the parent relationship, takes a commission on every lesson (commonly 20–40% depending on the platform and how long you've been on it), and constrains what you can teach, how you can price it, and often whether you can move a family to a direct arrangement. This is a fine on-ramp when you're getting your first students and testing whether tutoring is your full-time thing; it's a poor place to grow a business. Retention economics favour tutors who own their students — a family that renews with you month after month is worth many times a one-off marketplace booking, and none of that compounds if you don't own the relationship.

3. A purpose-built virtual classroom for young-learner tutoring (Koala Go is our version of this — there are several credible options in the category). Designed from the ground up for a tutor-and-child lesson, in a browser, on whatever device the child has at home. The teaching surface — interactive slides you can upload PDFs and PowerPoints into on paid tiers, a whiteboard the student can draw on and drag pieces around, and often a "cobrowser" that lets you and the student both click on the same live webpage — lives in the same tab as the video. Engagement is a first-class feature: rewards (badges, avatars, gems, a 3D playground) are built in so the tutor doesn't have to invent one every lesson. The business side (scheduling, invoicing, lesson recording for parents) is there too. The tradeoff is the tradeoff of independence: you have to bring your own students, and that is more work than a marketplace.

What actually matters in a lesson with a seven-year-old

Adult-lesson platform reviews evaluate things a young learner does not care about — screen-share polish, meeting recording defaults, calendar integrations. When you sit down for an actual phonics lesson with a five-to-nine-year-old, this is the short list of what changes the shape of the hour:

  • The student can touch and move things on the screen. Watching the teacher's cursor is not enough. A child disengages quickly from a passive screen-share. They need to drag a picture card onto the correct word, tap the letter that makes the /sh/ sound, drop the animal into its home. Any platform that requires the student to "request control" for that is losing the lesson before it starts.
  • The surface is one tab, not five. A young student cannot recover from "hold on, let me share the other window". Any moment you spend switching apps is a moment they check out. Everything the child interacts with should be in the same browser tab as your face on video.
  • There is a reward loop that doesn't require you to run it manually. Kids will work for badges, points, avatars, unlocks, and games — as long as the reward is intrinsic to the platform and consistent lesson to lesson. Inventing a new sticker chart every week is a real tax on prep time, and inconsistent kids will notice.
  • It behaves on cheap devices and shaky home Wi-Fi. Most of your students are on a parent's older iPad, a Chromebook, or a shared family laptop, on a home line the parent isn't monitoring. A platform tuned for a MacBook on office fibre will bleed lessons.
  • It works in the country where your students actually live. If a meaningful share of your students are in mainland China (a real segment for online ESL — and, in our own customer base, a big one), the platform needs a video, whiteboard, and any embedded webpage that can be reached from behind the Great Firewall without asking the family to install a VPN. This is genuinely hard, and no platform we know of makes it a solved problem — but a platform that has actually engineered for it beats one that hasn't.
  • The parent's side is simple and doesn't demand an account. Kids' ESL is bought by the parent. Anything the parent has to sign up for, install, or troubleshoot before the first lesson is friction that costs you conversion. Join-by-link, no download, no account is the right shape.
  • You can invoice the family without a separate tool. Especially for tutors billing across borders — a family in Shanghai paying a tutor in Toronto — the platform that wins is the one where the invoice comes out of the same place the lesson happens, in the parent's local payment methods (which for China means WeChat Pay or Alipay), without asking you to run Stripe, PayPal, and Wise in parallel.

Where Koala Go fits — and where it doesn't

Koala Go is a browser-based virtual classroom we build specifically for independent online tutors, and the ESL-of-young-learners tutor is a segment we hear from a lot. It is the platform we would pick for this shape of lesson, which is why we build it — with the honest caveats below.

For the ESL-of-kids audience specifically, the features that carry the lesson are:

  • An interactive whiteboard the student can drive. Load a slide with pictures and letter tiles the student drags around, hand the pen back and forth, drop images and shapes onto the canvas mid-lesson. Objects the tutor places on the slide are grabbable by the student without a permissions handshake — no "can you click OK on the request control prompt?" mid-lesson.
  • A cobrowser — a live shared webpage — for going out to real content together. When you want to visit a picture-book site, a phonics game, or a video and have both of you point-and-click on the same actual page (not just the student watching your cursor on a screen share), the cobrowser is what does that. It's region-aware — North America, Europe, or Asia — with a distinct route for mainland-China clients. Reliability in China is a live engineering focus for us, not a solved problem, and the honest framing on any China-heavy practice is "we route for it, and we respond fast when it breaks".
  • A 3D playground with the student's own avatar, used as a full-lesson environment or a brain-break reward. It's the engagement mechanic tutors of young students most often tell us their kids come back for.
  • Worldwide invoicing built into the classroom, paying out to your country and taking payment in the family's — including WeChat Pay for Chinese students, which is the rail that actually works there. No separate Stripe + PayPal + Wise stack.
  • A free plan good enough to run real lessons on, capped at four students per session, with a limited co-browser and worldwide invoicing at a 4.5% Koala fee. Not a trial — a real classroom, indefinitely.
  • Koala Pro at $25.99/month monthly, $21.99/month annual — which lifts the co-browser to unlimited, unlocks PDF and PowerPoint upload to the whiteboard, adds scheduling and translated student chat, and drops the invoicing fee to 3.5%. Local lesson recording (to your own machine) is on Pro too. Koala Platinum at $49.99/month monthly, $39.99/month annual adds cloud recording of scheduled lessons that you can share per lesson, plus auto-generated notes drafted from each recording.

Where Koala Go is a good fit: independent tutors teaching K-12 English to children (especially under-10s), where engagement is the whole game; reading and phonics tutors; tutors with families in mainland China; tutors who want their own brand rather than a marketplace's. Where it isn't the right pick: very large group formats, enterprise LMS deployments, and asynchronous "post-a-worksheet-and-grade-it" workflows.

A working process for choosing one

Two or three trial lessons will tell you more than a month of reading platform reviews. A recipe that works:

  1. Shortlist two platforms from different categories — one purpose-built kids' classroom and one alternative you're seriously considering. Don't trial three video-call tools; they're the same shape.
  2. Run one real lesson on each — not a demo, one of your actual weekly lessons with an existing student. A trial with a compliant demo child on your own device is misleading; a trial with a real seven-year-old on their tablet at home is the real test.
  3. Score three things after each lesson. How many minutes did the child stay engaged before the first check-out? How many times did you have to switch tabs or apps? How much of the lesson could the child do, versus watch?
  4. Ignore anything a demo alone could tell you. Slick onboarding, feature checklists, and vendor reviews don't survive first contact with a tired kid on a slow line. The platform that felt right after one real lesson almost always is right.
