Independent verification for AI agents

Your AI says done. We verify.

Runs that finish cleanly, look successful, and never did the job — stale reports presented as fresh, deliveries that never landed, polite refusals buried in polished text. Carell.ai is the independent verification layer that catches what your logs can't.

The problem

The failure your monitoring misses

Crashes page someone. Timeouts retry. But a run that completes politely and does nothing? It sails through every dashboard you have. These are real incidents — each one was marked success.

Looked delivered, wasn't

A daily report was generated flawlessly — and never reached its destination. The log said posted; the channel was empty. Nobody noticed for days.

log: "report posted to channel" reality: 0 messages found in read-back

Fresh-looking, stale content

A daily briefing confidently presented a two-week-old itinerary as today's plan — fluent, well-formatted, and wrong about what day it was.

log: "briefing delivered on schedule" reality: content dated 12 days earlier

A confident excuse

The agent explained — politely, at length — why it couldn't do the task, touched none of its required tools, and exited clean. Marked successful anyway.

log: exit 0, response delivered reality: 0 required-tool calls; task abandoned

How it works

Every run, checked against what a real run looks like

No changes to your agents. Carell.ai sits beside them, reads what they produced, and verifies it against a plain-language contract — with evidence for every verdict.

STEP 1

Connect

Point your agents' finished runs at Carell.ai — webhook, file drop, or telemetry. Minutes, not a migration.

STEP 2

Contract

Each task gets a plain-language contract of what a real run looks like. Assisted drafting writes the first version from your run history; you approve it.

STEP 3

Verify

Deterministic fact-checks — did it use its required sources, did the claimed delivery actually land, is it about today, did it die mid-flight — plus a calibrated AI reviewer. Verdicts are evidence-backed, never vibes.

STEP 4

Trust

A daily digest lands where your team works. One-tap review of flagged runs trains the system, and a signed trust report accrues into the “Carell.ai Verified” credential.

The AI reviewer is guilty until proven calibrated. It can only advise — flag, never fail — until its track record against your own confirmations earns it more. Judgment stays accountable to evidence.
Updates never touch your files. Every upgrade cryptographically verifies that your contracts, tuning, and history are byte-for-byte untouched — and posts plain-language release notes about what changed.

Proof

We are customer zero

Carell.ai runs every day against our own production agent system — the same engine, the same contracts, the same digests we ship. First week of results:

27runs independently verified
7real failures caught
5of them previously invisible to an attentive operator
0false positives

Every verdict above is backed by a stored evidence record — and the product’s own release gate verifies the verifier before any version ships.

Why this exists

Monitoring catches crashes. Verification catches lies.

The industry shipped AI agents faster than the ability to check them. Uptime, latency, error rates — the whole observability stack watches whether the run finished. None of it watches whether the run did the job.

An agent that fails loudly is a solved problem. The dangerous one finishes on time, writes fluent output, reports success — and quietly delivers nothing, or worse, yesterday's world presented as today's. The more polished the output, the longer the failure survives.

“A result that never reached its destination didn't happen — no matter how good it looks in the logs.”

Carell.ai closes that gap with something your own tooling structurally can't provide: an independent check. Self-review is how fabricated citations end up in published reports. A verification layer that answers to the evidence — not to the team that built the agent — is the difference between “it said it worked” and “it worked.”

We run it on our own agents every day. Our failures were the training data; our deployment is the first customer.

Trust & security

Built for the buyer who reads the security page first

A verification product earns trust the same way it grants it: structurally.

Self-hosted by design

The engine runs inside your network. Your run data, transcripts, and results never pass through us.

Your keys, your models

The AI-review step runs on your own model accounts — verification costs are visible and reconcilable on your own bill.

Minimal egress

Only a report hash and summary counts ever leave — for independent countersigning. Never the report text, never your data.

Advisory, never automatic

Every recommendation is something you review, test, and decide on. Nothing is auto-applied to your agents.

Continuity, in writing

Self-hosted means it keeps running whether or not we do — backed by source escrow and a runbook your own team could operate.

Independent by structure

We are the third party your own team, by definition, cannot be. Independence is the product, not a feature of it.

Get started

Try it for $5

Start with a single scheduled task for $5 — the full product for 90 days, one payment, nothing to cancel — or a guided audit of your agent fleet. No dashboards to learn, nothing to rip out — results land where your team already works.

What to include: what your agents do, roughly how many scheduled tasks you run, and where results should land (terminal, webhook, Slack, Discord…).
