Limits and method

23

Limitations and open questions

Known constraints and missing evidence from the collected pages.

The collected pages do not name competitors. Pricing details are incomplete for enterprise plans. Customer reviews are scarce—only one unnamed quote S105. Evidence for data ownership and export is absent.

24

Sources, method, and limitations

Evidence inventory, collection method, provider use, and constraints.

This report is based on 15 collected pages from knock.app, including static and rendered pages, plus an external proof search. The external search verified references to agent integrations but did not collect third-party reviews or ratings. Limitations: marketing pages may overstate capabilities; detailed documentation and enterprise contracts were not part of the collection.
