What Preply genuinely does well
- Private 1-on-1 lessons. No group dynamics, no shared pace. The entire session is yours, adapted to your level and goals.
- Tutor matching at scale. Thousands of Spanish tutors with video introductions, ratings, and speciality tags. You can find a Peninsular specialist if you look.
- Structured plans from tutors. Good Preply tutors build a learning plan for you, assign homework, and track your trajectory — at least in theory.
- Flexible scheduling. Book sessions around your life. Reschedule without drama.
- Human judgement. A skilled tutor reads your face, hears your hesitation, and knows when to push and when to simplify. No AI matches this yet.
A great private tutor on Preply is genuinely hard to beat for the hour you’re together. The question is what happens in the hours you’re apart.
The 167-hour problem
You book three sessions a week. That’s three hours. The week has 168. Here’s what happens in the other 165:
- No structured practice. Preply is a marketplace, not a practice platform. Homework depends entirely on your tutor — and most learners don’t do it consistently even when it’s assigned.
- No persistent error model between sessions. Your tutor corrects you in real time, but there’s no system that logs those corrections, categorises them, and schedules re-exposure. Next week, the same errors may or may not resurface.
- No avoidance detection. Your tutor might notice you dodge the subjunctive in conversation. But tracking avoidance patterns across months of sessions requires a system, not a memory.
- Cost scales with contact time. Want more practice? Buy more hours. At $15–50/hour, daily practice via Preply would run $450–1,500/month. That’s not a realistic option for most learners.
- Tutor quality variance. The marketplace model means quality is inconsistent. A brilliant tutor gives you curriculum-grade instruction; a mediocre one gives you paid conversation.

Choose Preply instead if…
- You’re early in your journey and need a human to build confidence and correct pronunciation in real time.
- You’ve found a great tutor who genuinely tracks your progress and assigns targeted work.
- Social accountability is what keeps you showing up.
- Budget isn’t a constraint and you want maximum contact hours.
How they work together
This is the pairing that makes both tools worth more:
Keep your Preply tutor for the weekly session — the human connection, the cultural context, the real-time adaptation. Use Suelto for the other six days: daily practice built from your actual weak points, spaced repetition that resurfaces what wobbled, scenarios that force the structures you avoid.
Your tutor stops starting from scratch each week. Your practice days stop being empty. The expensive hour compounds instead of evaporating.
The test
The gap test shows the distance between what you understand and what you produce. If your tutor has already closed that gap, you’ll see it. If the gap is wide despite months of sessions, you’ve found the work that belongs between them.
UNDERSTAND THE PLATEAU
The comparisons make more sense once you see the plateau they’re built to fix.
