Approvals your AI agents can't skip.
When your agent is about to move money, issue a refund, or change an account, Approv gets a real human's yes/no on WhatsApp — and keeps a tamper-proof record of every decision.

Do you approve?
How it works
One API call. One human. One receipt.
Your agent asks
One API call when it hits a risky action. Nothing runs until a human decides.
A human taps yes/no
The right person gets a clear Approve / Reject on WhatsApp, with SMS fallback.
You get a signed record
The decision returns to your agent, and every step is written to a tamper-proof audit trail.
Why Approv
"Sent" is not "approved."
Delivery that lands
WhatsApp-first with automatic SMS fallback, retries, and a live delivery trail. The message reaches the human — or you know exactly why not.
Tamper-proof audit
Every step is hash-chained and Ed25519-signed. Anyone can independently verify a decision wasn't altered. Export-ready for auditors.
A control, not a notification
The action is bound to the approval. First reply wins — a decision can't be flipped, faked, or double-answered.
Compliance-ready
The human-oversight step and audit trail the EU AI Act asks for — a few lines of code, not a project.
Put a human in the loop in minutes.
Create an account, add an approver, and send your first approval — no credit card.
