Inclusion rule. The nine hooks every tool in the register is read for. Order. The order hooks take on every tool page.

1Where they part

Synthesia documents file formats, which Kling AI's pages leave out. For API access the two match: an API for its own models. For agent hooks, Kling AI names an agent skill and Synthesia an MCP connection. For resolution, Kling AI names 4K for images only and Synthesia 1080p. For downloads the two match: a link or file that expires. For job signals the two match: a webhook or callback URL. Neither documents editing hand-off, subtitle files or SDKs.
