Currently, you can add Knowledge from uploaded or cloud-hosted files, with more data sources coming soon. Learn more here.

π Share any Workflow as a Template
Turn any workflow into a ready-to-use, importable template via a unique (private) link. Templates can be shared with anyone you choose and help them quickly adopt and build upon workflows you've crafted.

π Add optional human reviews to any AI step
Weβve expanded our Human-in-the-Loop capabilities and added support for optional reviews for any AI step. Reviews give your team the ability to approve, revise or override the AIβs output effortlessly.
