When AI agents act on your behalf, some actions can't be undone. The Last Word makes sure a human approves — and signs — every irreversible step.
Type what you want done. The agent prepares everything.
The Last Word shows what you asked vs what the agent prepared — side by side.
You have the final say. Approve to execute, or reject to block it.
Tell the agent to pay an invoice or delete data. Watch it prepare the action, then approve or reject at the gate.
Try: Pay invoice #2041 for $1,200 to Acme Corp or Delete my account and all data
Every action is recorded in a tamper-evident hash chain — each entry links to the previous via prevHash and is sealed with an ECDSA signature. Persisted in your browser, it survives reload and detects any tampering.
