The short version

  • Only Brilliant has a free tier, so it costs nothing to try first.
  • Each has a real cost: Brilliant requires active daily engagement to maintain learning streaks, which can feel gamified; Gaggle pricing is quoted per student per year with no published rate, and because it is charged on total enrolment rather than on accounts actually monitored, small districts pay a markedly higher effective rate than large ones.
  • They diverge on capability: Brilliant covers Interactive lessons, Gaggle covers Content scanning.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Brilliant

  • Requires active daily engagement to maintain learning streaks, which can feel gamified
  • Premium subscription needed for full course access; basic free tier is limited
  • Focuses only on STEM subjects; no humanities or social sciences
  • Interactive nature requires more time commitment than passive video learning

Gaggle

  • Pricing is quoted per student per year with no published rate, and because it is charged on total enrolment rather than on accounts actually monitored, small districts pay a markedly higher effective rate than large ones.
  • False positives are structural, not a tuning problem: fiction assignments, song lyrics, health coursework and jokes between friends all trigger review, and each escalation consumes counsellor time the district funds itself.
  • The service reads children's private writing on school accounts, and civil liberties groups have documented cases where flagged content led to outing LGBTQ students or to discipline rather than support, which is a governance risk a board must accept explicitly.
  • Coverage is limited to district-issued accounts, so a student using a personal phone, a personal email address or an encrypted messaging app is invisible, which is where much of the behaviour the district worries about actually happens.
  • Escalation depends on the district maintaining accurate contact lists and staff who answer calls; when a named contact leaves and the list is stale, the service escalates into a void and the district only discovers it after an incident.

Answered from the vendors’ own pages

Brilliant: Does Brilliant offer offline learning?

Yes. The Brilliant mobile app allows users to download lessons and learn without internet connection.

Source
Gaggle: How much does Gaggle cost?

It is quoted per student per year based on enrolment and requirements. No rate card is published, and effective rates fall substantially with district size.

Brilliant: Is there a free tier for Brilliant?

Yes. Brilliant offers a free basic tier with access to some courses. K-12 teachers and their students can qualify for free Premium access.

Source
Gaggle: Is the tipline an extra charge?

No longer. From 1 July, districts on the full Safety Management solution get SpeakUp for Safety and the web filter safety integration at no additional cost; each previously carried a per-student charge.

Brilliant: What subject areas does Brilliant cover?

Brilliant covers over 90 courses across mathematics, computer science, physics, chemistry, and data science, taught by experts from MIT, Harvard, Google, and Microsoft.

Source
Gaggle: Do humans read every alert?

Trained reviewers assess flagged items before escalation. That human layer is the core of the service, not an optional tier.

Brilliant: How does Brilliant's teaching approach differ from video lectures?

Brilliant emphasizes active learning through interactive problem-solving rather than passive video watching, similar to Duolingo's gamified approach.

Source
Gaggle: Does it monitor personal accounts or phones?

No. It covers district-issued Google or Microsoft accounts. Personal devices, personal accounts and encrypted apps are outside its reach.

Gaggle: What are the privacy obligations?

Districts sign a data processing agreement covering FERPA and applicable state student privacy law. Negotiate retention and scope in that document rather than relying on the marketing page.
