The short version

  • Only Busuu has a free tier, so it costs nothing to try first.
  • Each has a real cost: Busuu the free tier is limited enough that meaningful progress in most languages effectively requires the Premium subscription within a few weeks of use.; Lightspeed Systems no module has published pricing, so districts cannot benchmark a quote without running a formal procurement, and the eventual figure depends heavily on which co-operative contract they buy through.
  • They diverge on capability: Busuu covers Structured course units, Lightspeed Systems covers Filter.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Busuu

  • The free tier is limited enough that meaningful progress in most languages effectively requires the Premium subscription within a few weeks of use.
  • Community correction quality depends on other users being active in your target language at the time you submit, so response speed and quality vary noticeably by language and time zone.
  • Since the 2022 Chegg acquisition, Busuu sits inside a company built around subscription homework and study services, and Chegg has faced its own commercial pressure from AI tools reducing demand for its core products, which is a relevant roadmap risk.
  • Course depth and language coverage are uneven; widely spoken languages such as Spanish and French have far more content than smaller language courses.
  • The official Busuu certificate is not a recognised external qualification equivalent to something like an IELTS or DELF exam, so it carries limited weight outside informal use.

Lightspeed Systems

  • No module has published pricing, so districts cannot benchmark a quote without running a formal procurement, and the eventual figure depends heavily on which co-operative contract they buy through.
  • Alert detection and the 24/7 human review that makes it actionable are priced separately, so a district that budgets for Alert alone ends up owning the overnight triage burden itself.
  • The agent model means coverage stops at the managed device, and students moving to a personal phone on mobile data are outside filtering and monitoring entirely, which undercuts the compliance claim in the exact scenario administrators worry about.
  • Teacher screen monitoring is frequently deployed without training, and lessons stall while staff learn the interface, so the first term of a Classroom rollout often produces complaints rather than the intended benefit.
  • Buying eight modules from one vendor makes renewal a single high-value negotiation with no partial leverage, and districts locked into a multi-year co-operative contract cannot easily drop a module that underperforms.

Answered from the vendors’ own pages

Busuu: Is Busuu free?

A limited amount of vocabulary and grammar content per language is free with ads. Full course access, offline lessons and the certificate require Busuu Premium.

Lightspeed Systems: How much does Lightspeed Filter cost per student?

Lightspeed does not publish rates. Pricing is quoted per student device per year and varies with district size, module mix and which purchasing co-operative contract you buy through.

Busuu: Who owns Busuu?

Chegg, the publicly traded US education technology company, acquired Busuu in 2022.

Lightspeed Systems: Is 24/7 human alert review included with Alert?

No. Alert provides the detection; the staffed round-the-clock review service is an additional purchase, and it is usually what districts actually need.

Busuu: What is the community correction feature?

Writing and speaking exercises are submitted to other Busuu users who are native speakers of your target language, who correct them for free as part of the community exchange.

Lightspeed Systems: Does filtering work when students are at home?

Yes, the agent runs on the device rather than the network, so policy follows the Chromebook or laptop off site.

Lightspeed Systems: What does Insight actually do for the budget?

It reports which licensed apps are opened and by whom, which districts use to cancel subscriptions with low usage. It also flags whether an app meets named privacy and accessibility standards.
