Comparison
Ceereo vs CommonLook for Accessible PDFs
CommonLook (now part of Allyant) is the specialist ecosystem: professional desktop tooling for deep remediation and validation, plus human services — the choice of dedicated accessibility teams. Ceereo is the self-serve counterpart: free audit, automated remediation with machine + pixel verification, per-document pricing, zero training. Specialists doing complex work pick CommonLook; document owners who need files fixed pick self-serve.

CommonLook's tools (PDF GlobalAccess and the CommonLook validator) are respected exactly where depth matters — dedicated specialists remediating and certifying complex documents, often alongside Allyant's human services. That world runs on expertise and licenses. Ceereo serves the other 90% of situations: someone has a PDF, a deadline, and no tag-tree training. Upload, audit free, download the verified fix. Below is the honest split.

Where CommonLook wins
Specialist depth
Standards-grade validation and manual remediation tooling for the hardest documents.
Human certification
When you need a person to attest conformance, their services provide it.
Complex tables & forms
Professional tooling handles what automation flags or declines.
Where Ceereo wins
Accessible to non-specialists
No license, no training, no tag vocabulary — the audit explains itself in plain English.
Speed and price shape
Minutes and per-document pricing versus operator hours or engagement quotes.
Built-in evidence
Every fix ships with the re-audit and a pixel-identical proof automatically.
You can use both together
Use self-serve for the routine tail; bring CommonLook tooling or Allyant services in for certified, complex, or scanned work. The report from here slots into that escalation cleanly.

Veermat vs CommonLook: frequently asked questions
Can Ceereo replace a specialist?+
For the machine-checkable layer on routine documents, yes — and it proves it per file. For certified conformance and genuinely complex layouts, specialists remain the answer; we say so on the report.
Is your verification the same as CommonLook validation?+
Ours is automated PDF/UA machine checking plus pixel-diff; theirs includes standards-suite validation driven by professionals. Same family, different depth — and ours ships with every fix by default.
Which is cheaper?+
For occasional documents, per-document self-serve by a wide margin. For a staffed program running thousands of complex pages, licensed tooling amortizes.
