The human oversight platform
for AI agents and workflows.
Helping operations teams work alongside AI. Review, approve, and correct outputs before AI mistakes reach your systems.
Core capabilities
Built for humans and AI
to work together.
Everything your operations team needs to stay in control of AI outputs, from the first review to the final audit.
Review interface
One screen to review any AI output.
Your reviewer sees exactly what the AI worked with and what it produced, side by side. Approve, reject, or correct the output in seconds, without switching tools.
Audit trail
Every decision, logged automatically.
Every review, correction, and approval is recorded as it happens. If a decision is ever questioned, the full history is documented.
Continuous improvement
Every correction makes your AI more accurate.
When a reviewer fixes an AI error, Approvio records exactly what was wrong and what the right answer was. Your AI gets more accurate over time.

How it works
From AI output to human decision
in minutes.
Approvio connects to any AI agent or automation tool. Your workflow sends an output, a reviewer approves it, and the result flows back automatically.
Your AI sends an output to Approvio.
One step added to your existing workflow. Set up in minutes, no new infrastructure.
Your reviewer gets a link, wherever they work.
Email, Slack, Microsoft Teams. They open one screen with everything they need to make a decision.
They approve, reject, or correct.
The result is sent back to your workflow automatically.
For developers
One request to add a human
checkpoint to any workflow.
Send a POST request with your payload, a template ID, and a callback URL. Approvio handles the review interface, notifications, and audit trail. You just receive the result.
- No SDK required — Plain HTTP — works from any language or tool.
- Works with any AI agent or automation tool — If it can make an HTTP request, it can use Approvio.
- Webhook-based — Receive the approved payload at your callback URL.
When the reviewer approves, Approvio POSTs the result — including any edits and a full change log — back to your callback_url.
Integrations
