Pendo

Pendo combines product analytics with in-app guidance: it measures feature usage and also displays tooltips, walkthroughs and surveys inside the product.

Its measurement side is built on automatic capture of interactions, while the guidance side lets a product team place a message or walkthrough on the page without shipping a release. That combination is why it is popular with onboarding and adoption teams. It also carries an analytical trap: when one tool both delivers the intervention and reports its effect, higher adoption after a walkthrough is not proof the walkthrough caused it, because the users who saw it were already more active. Claiming an effect requires showing the guide to a random subset and keeping a control group beside it.
