Verified by Humans is a verification marketplace that connects credentialed domain experts with AI-powered services. When an AI agent completes a task — such as filing taxes, analysing medical records, or drafting a contract — a qualified human expert reviews the output for accuracy, compliance, and completeness before it reaches the end user.

The process follows three steps. First, an AI agent completes a task at machine speed. Second, a certified domain expert — such as a CPA, doctor, or lawyer — conducts a substantive review of the AI's output, checking for factual accuracy, regulatory compliance, and professional standards. Third, the verified output receives the "Human Checked" seal, which links to a public verification record showing who checked it, their qualifications, and when the review was completed.

Our expert network includes certified public accountants (CPAs), tax advisors, licensed physicians, attorneys, professional engineers, and financial analysts. Each expert is vetted for active credentials, professional licensing, and domain-specific experience before joining the platform.

The "Human Checked" seal is a certification badge that AI companies can display on verified outputs. Each badge links to a tamper-proof verification record containing the reviewer's name, professional credentials, the scope of review, and a timestamp. It serves as an auditable proof that a qualified human expert stood behind the AI-generated work.

AI companies integrate through a simple API that routes their AI-generated outputs to the appropriate domain expert for review. The integration requires minimal engineering effort — typically a single API call to submit work for verification and a webhook to receive the verified result. Companies gain access to the full vetted expert network and can display the "Human Checked" badge on approved outputs.

AI systems can produce outputs that appear authoritative but contain factual errors, regulatory non-compliance, or professional oversights — particularly in high-stakes domains like tax filing, healthcare, and law. Human verification by a credentialed expert catches these errors before they reach end users. As AI agents handle increasingly consequential tasks, independent human oversight becomes essential for accountability, legal compliance, and user trust.

Credentialed professionals can join the expert waitlist above. Once the platform launches, accepted experts set their own rates and availability, review AI outputs asynchronously from anywhere, and build a public reputation as a trusted verifier. The platform currently accepts CPAs, tax advisors, doctors, lawyers, engineers, and financial analysts.

Verification time depends on the complexity of the task and the domain. In our pilot scenarios, an AI tax agent completed a full federal and state filing in approximately 4 minutes, and a CPA verified the output in approximately 25 minutes. The combination of AI speed and expert review delivers both efficiency and accuracy — work that previously took hours is completed and verified in under 30 minutes.
