Per-criterion
There is no italki Spanish curriculum — content quality is whatever the tutor brings. Professional teachers arrive with structured DELE prep, grammar plans and homework; community tutors lean on free-form conversation. Spanish-specific reviewers note the ceiling is high (subjunctive drilling, regional dialect work, exam prep) but the floor depends entirely on careful tutor selection and on the learner directing the sessions.
The strongest dimension. italki's Spanish pool is enormous — nearly 2,000 teachers spanning professional teachers with verified credentials and native community tutors across Spain and Latin America. Reviewers converge that a well-chosen Spanish tutor is the single highest-leverage thing they did. Verification screens out the worst, but the gap between an excellent teacher and a merely adequate one is real and unscreened.
Spanish is one of italki's best-supplied and cheapest languages. Latin American community tutors often run $4-9/hour; professional teachers $15-30. No subscription — pay per lesson. Reviewers repeatedly flag $10/hour for a native Colombian or Mexican tutor as one of the best deals in language learning, far below local classes or Spanish-only subscription competitors.
No streaks or gamification — you book and show up, or you don't. Learners who pre-commit to a weekly slot describe it as the most durable Spanish habit they built; without a schedule it lapses. The pre-paid credit system acts as a mild commitment device. The lack of a built-in progression path is the most-cited drag on long-term motivation for learners who want a course to follow.
Platform support handles payment, scheduling, cancellation and dispute resolution effectively. The 24-hour cancellation window is fair and refunds/rescheduling are reported as straightforward. The notebook and community-exchange features are active but secondary. The main support gripe is the no-refund-on-loaded-credit policy.
The clearest signal in the sample. Real conversation with a native Spanish speaker is the most direct path to fluency, and Spanish learners repeatedly describe italki as the step that moved them from app-bound recognition to actual conversation — exposing gaps (preterite at speed, ser/estar, subjunctive) that apps never surface. Multiple reviewers report passing B1/B2 CEFR exams after consistent use.
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.
