Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Clever
- Coverage is built around United States district data models and state reporting patterns, so schools outside the United States often find their student information system unsupported and their local identity conventions unrepresented.
- Because application vendors pay and districts do not, a district has no commercial leverage when a sync breaks, and support priority follows the paying side of the market.
- Rostering is a single point of failure. One bad field mapping propagates wrong class lists to every connected application at once, and unpicking it means correcting the source system and waiting for the next sync cycle.
- Sync is scheduled rather than immediate for many connections, so a pupil who transfers mid week can sit in the wrong class in several applications for a day or more.
- Ownership moved to Kahoot! in 2021 and then to a private equity consortium in 2023, so a district is now depending on infrastructure whose long term roadmap is set by investor timelines rather than by education procurement cycles.
Duolingo
- Free tier includes ads and energy-based hearts system limiting daily practice without paying
- Gamification focus may appeal to casual learners but lacks depth for serious language study beyond conversational basics
- Limited to short, bite-sized lessons without extensive grammar explanations or cultural context

Answered from the vendors’ own pages
Clever: Does Clever really cost a district nothing?
The core rostering and single sign-on service is free to districts. Application vendors pay for the connection and build that cost into what they charge the district, so the money reaches Clever through the software bill instead of a direct invoice.
Duolingo: What is Duolingo's pricing model?
Duolingo offers free tier with ads and limited features, Super Duolingo at $12.99/month (ad-free, unlimited hearts, extra practice), Super Family at ~$119.99/year for up to 6 users, and Duolingo Max with AI features like Video Call and Roleplay.
SourceClever: Is Clever FERPA and COPPA compliant?
Clever operates as a school official under FERPA, acting on district instruction, and relies on district consent rather than parental consent for COPPA. It has signed the Student Privacy Pledge.
Duolingo: Is Duolingo effective for language learning?
Duolingo has 135+ million monthly active users as of Q3 2025, making it the world's most widely used language-learning app. Its gamified approach and free tier have driven massive adoption.
SourceClever: What happens if we leave Clever?
Every connected application loses its roster feed and needs a replacement method, either a competing rostering service or manual CSV uploads per application. That is why districts rarely switch once more than a handful of applications depend on it.
Duolingo: What AI features does Duolingo Max include?
Duolingo Max includes Video Call for conversation practice with AI character Lily and Roleplay for scenario-based speaking practice. As of January 2026, Explain My Answer became free for all users.
SourceDuolingo: Does Duolingo work offline?
Duolingo is primarily online, though it may offer limited offline lesson downloads on some platforms. Full features require internet connection.
