italki Group Classes vs Duolingo Max
Same Bayesian formula, same rubric — so the difference in scores reflects the difference in the courses, not the difference in how we evaluated them.

Per-criterion
Class topics span daily conversation to exam prep and debate — stronger than a blank-slate tutor session. But content quality varies by teacher and sessions repeat across a small topic roster. No graded curriculum arc linking one class to the next.
Group-class teachers on italki are professional teachers, not community tutors. Quality is generally consistent, but instructors must manage mixed-level groups, which compresses individual attention. Teacher profiles and reviews are browsable before booking.
At $7–12 for a one-hour group session the per-class price is hard to beat. Value flips if you compare per-minute of actual speaking time to a $10 community tutor — groups give you roughly 10–15 minutes live output per hour versus 60 on 1-on-1.
italki's platform support is adequate but not fast. Group-class refund policy requires cancellation 24 hours in advance. Live chat exists but resolution times for payment disputes are inconsistent per reviewer reports across the wider italki sample.
Speaking in front of peers under mild social pressure is genuinely useful output practice. Topic-focused classes (news, interview prep, travel) transfer directly. Ceiling is lower than 1-on-1 because correction is shared and spontaneous exchanges are shorter per learner.
Same Duolingo curriculum as Super with three AI bolt-ons — Explain My Answer, Roleplay, Video Call. AI explanations sometimes get grammar wrong and Roleplay topics are narrow, so the content lift over Super is real but modest.
The "instructor" is GPT-4 behind a Duolingo wrapper. It can explain basic grammar and hold a short roleplay, but multiple reviewers report it makes mistakes and is much narrower than ChatGPT/Claude direct, and far below an italki tutor on actual correction quality.
Roughly $30/month — more than 2× Super's $13. Reviewers flag that ChatGPT Plus/Claude Pro ($20) cover the AI capability with no topic limits, and a weekly italki lesson ($10-15) buys real human correction. Weakest dimension by a wide margin.
Inherits Duolingo's streak engine, leaderboards and daily quests — the strongest retention layer in the category. Max-specific features add little; reviewers describe the AI call as a "try one free, then upgrade" upsell rather than a habit driver.
Roleplay forces some output production, structurally better than Duolingo's tap-the-tile drill, but topic scope is narrow and it does not replicate real-conversation unpredictability. Better than Super at speaking, still well below a live tutor.
