HumanLayer is an API and SDK that enables AI Agents to contact humans for feedback, input, and approvals.
Guarantee human oversight of high-stakes function calls with approval workflows across slack, email and more.
Bring your LLM and Framework of choice and empower your AI agents with safe access to the world.
The @hl.require_approval() decorator blocks specific function calls until a
human has been consulted - upon denial, feedback will be passed to the LLM.
Generic hl.human_as_tool() allows for contacting a human for answers, advice,
or feedback.
Contact humans and collect responses across Slack, Email, Discord, and more.
Route approvals to specific teams or individuals.
Coordinate approvals across multiple teams and individuals with escalations and timeouts.
Because HumanLayer is implemented at tools layer, it supports any LLM and all major orchestration frameworks that support tool calling.
Free forever for Hackers and Tinkerers
Collaborate and scale
An active user is any user that is registered to approve or respond to agents.
Learning and Auto Approvals allow you to set a threshold for automatically approving or denying requests based on past human interactions.
Escalations and Timeouts allow you to coordinate approvals across multiple teams and individuals with escalations and timeouts.
Supports Promise.race() and Promise.all() semantics.
With HumanLayer, you can take the live feedback from your Human SMEs and periodically export it to one or more high-fidelity labeled datasets to power either fine-tuning, evals, or both.
