What is Amplitude and what is it used for?
Amplitude is a product analytics platform that shows what users do in an app or website, with event analysis, conversion funnels, retention, cohorts and experimentation.
Product, data and marketing teams use Amplitude to answer questions such as where users drop out of sign-up, which features bring people back and whether a screen change improved conversion. Analyses are built from charts, with no SQL required.
Collection depends on instrumentation: the team decides which events to log and sends them with the documented SDKs. On top of those events, Amplitude offers journey analysis, user groups that can be reused across charts, A/B tests, session replay and in-product guides and surveys.
There is a free plan, paid plans priced by event volume and a startup program. The descriptions come from the vendor itself.
