The short version
- Only Flowkey has a free tier, so it costs nothing to try first.
- Each has a real cost: Flowkey microphone-only users, without a MIDI keyboard, still hit the same accuracy limits as Simply Piano on fast or dense passages.; 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: Flowkey covers Large licensed song library, Gaggle covers Content scanning.
- 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.
Flowkey
- Microphone-only users, without a MIDI keyboard, still hit the same accuracy limits as Simply Piano on fast or dense passages.
- Its curriculum is less structured around fundamentals than Simply Piano for a complete beginner with no prior reading ability.
- It is piano only, so a household wanting to cover guitar or other instruments needs a separate subscription elsewhere.
- The song licensing model means catalogue availability can shift over time as licences change, occasionally removing a previously available arrangement.
- Full benefit of its more precise feedback mode requires owning a MIDI-capable keyboard, which is an additional cost beyond the subscription for anyone with only an acoustic piano.
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
Flowkey: Does Flowkey support MIDI keyboards?
Yes, connecting a MIDI keyboard gives more precise note detection than microphone listening alone.
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.
Flowkey: How is it different from Simply Piano?
Flowkey emphasises a large licensed song catalogue with graduated arrangements, while Simply Piano leans more into a structured beginner curriculum.
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.
Flowkey: Do I need a MIDI keyboard to use it?
No, microphone listening works with any piano, but MIDI support improves accuracy if you have compatible hardware.
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.
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.
