The short version

  • Only Duolingo has a free tier, so it costs nothing to try first.
  • Each has a real cost: Duolingo free tier includes ads and energy-based hearts system limiting daily practice without paying; Infinite Campus no pricing is published anywhere, so the only way to know what it costs is a sales conversation against your certified enrolment, and districts routinely discover the quoted rate differs from a neighbouring district of similar size.
  • They diverge on capability: Duolingo covers 40+ languages, Infinite Campus covers Per-student single licence.
  • Prices and features above were last checked on 31 August 2026.

  • Career developmentnot Infinite Campus

Infinite Campus

  • A district leaving a private-equity-owned SIS after a repricing or a support quality drop, and specifically wanting an owner whose roadmap is not on an exit clock.not Duolingo
  • A state education agency standardising every district on one SIS and one reporting extract so state submissions stop being a per-district reconciliation exercise.not Duolingo
  • A secondary school with complicated timetabling, block schedules, dual enrolment and weighted GPA rules that a simpler SIS cannot model without workarounds.not Duolingo
  • A district that wants meal accounts, fee payments, health records and special education in the same record as attendance and grades rather than integrated across four vendors.not Duolingo

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

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

Infinite Campus

  • No pricing is published anywhere, so the only way to know what it costs is a sales conversation against your certified enrolment, and districts routinely discover the quoted rate differs from a neighbouring district of similar size.
  • The interface is dense and inherited from an earlier era of web software; staff who use it occasionally, such as substitute teachers or front office cover, need retraining each time rather than working it out.
  • Implementation is a data conversion project, not an install, and districts that underestimate historic transcript and special education record migration end up running two systems in parallel for a year.
  • Getting real value out of it requires at least one dedicated district-level Campus administrator, which is a salaried post smaller districts often cannot justify and which becomes a single point of failure when that person leaves.
  • It is overwhelmingly a US product tuned to US state reporting; international schools and non-US systems get little of the compliance value that justifies the price, and the grading and enrolment models assume American conventions.

Answered from the vendors’ own pages

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.

Source
Infinite Campus: Does Infinite Campus publish its per-student price?

No. Every quote is negotiated against your certified enrolment, and public procurement records are the only reliable way to see what comparable districts actually paid.

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.

Source
Infinite Campus: Is it owned by a private equity firm?

No. It is privately held and founder-controlled, and has taken no venture or private equity investment, which distinguishes it from PowerSchool under Bain Capital.

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.

Source
Infinite Campus: Can it replace a separate LMS?

Partly. It has assignment and gradebook tools, but districts running Canvas, Schoology or Google Classroom keep them and integrate rostering rather than dropping them.

Duolingo: Does Duolingo work offline?

Duolingo is primarily online, though it may offer limited offline lesson downloads on some platforms. Full features require internet connection.

Source
Infinite Campus: How long is a typical contract?

Multi-year. Annual-only terms are unusual because the implementation cost is front-loaded and neither side wants to repeat it.

Infinite Campus: What happens to the price when enrolment falls?

It is tied to the enrolment snapshot, so declining districts should confirm the contract reprices downward rather than holding a floor.
