AccessSure vs CommonLook — an honest comparison from a working accessibility lab.

CommonLook is the legacy industry standard for PDF accessibility remediation. It has been the default answer in US Federal procurement for two decades. It produces PDF/UA-conformant output reliably, has an active user community, and is now part of Allyant following the 2022 consolidation of several accessibility tooling companies. Their team includes some of the most respected practitioners in the industry. If you have used CommonLook for years and the workflow fits your team, this article is not telling you to switch.

What this article is doing is answering a question we get every month from accessibility teams in India and Southeast Asia: "Is there a tool that works the way CommonLook does, but at our content's language, our team's training level, and our budget?" For most of the last decade, the honest answer to that question was no. As of 2026, the answer is yes — for a specific kind of buyer. This piece explains who that buyer is and where the comparison actually lands.

01 · Two different remediation models

The deepest difference between these tools is not feature-by-feature — it is the operating model each one assumes. Once you see the model difference, every other comparison point falls out of it.

CommonLook — operator-led semi-automation

CommonLook PDF is a Windows desktop application. A trained accessibility specialist opens a document, walks through it page by page using the application's tagging UI, fixes reading order in the Logical Order panel, applies alt text manually (or reviews AI-suggested alt text in newer versions), validates against PDF/UA and WCAG using the built-in validator, and exports. The tool dramatically accelerates what would otherwise be hand-edits in Adobe Acrobat Pro. It does not eliminate the operator. Their training, judgment, and time are the bottleneck.

Typical document throughput: one to three hours per document at moderate complexity, faster for simple documents, longer for complex tables and forms. A skilled operator running CommonLook full-time can process roughly 200 to 400 documents per year at acceptable quality.

AccessSure — autonomous-first with manual escalation

AccessSure PDF is a browser-based service at pdf.accesssure.in. The user drags a PDF onto the page. An AI pipeline — thirteen-language OCR, AI-driven object detection for figures and tables, AI-generated alt text and document titles, deterministic tag-tree construction — runs autonomously. Sixty seconds later, the user downloads a remediated PDF plus an audit bundle, with the score verified by veraPDF.

Typical document throughput: sixty seconds per document, regardless of operator training. The bottleneck is not labour; it is the AI model's accuracy on edge cases. For documents the AI handles confidently, this scales to thousands of pages per day per workspace. For documents the AI flags as low-confidence — complex nested tables, novel layouts, scanned documents with poor source quality — the recommended fallback is manual remediation through the ITQCR audit lab.

02 · The feature matrix, honestly

Where each tool genuinely wins, in our reading of both. We are not claiming AccessSure wins everywhere. CommonLook has a decade-plus head start on a deep, mature feature surface.

03 · The language question

This is the single biggest functional difference, and the one that most often determines which tool an Indian compliance team should pick.

CommonLook's tagging engine and OCR pipeline were built assuming Latin-script content. The application's UI accepts Indic input where the operating system supports it, and Indian-language OCR can be configured at the OS level. But this is configuration, not productization. There is no native Hindi or Tamil pipeline — there is a generic OCR engine that can be pointed at Indic content with mixed results. We have tested it. Output on Devanagari and Tamil source documents is workable for simple cases and degrades quickly with mixed bilingual layouts or stylised fonts.

AccessSure was built the other way around. The thirteen Indian scripts are first-class citizens of the pipeline. Hindi, Tamil, Telugu, Bengali, Marathi, Gujarati, Kannada, Malayalam, Punjabi, Odia, Assamese, Urdu, and English — each handled with dedicated language models, language-specific post-processing for OCR confidence improvement, and surfaced in the output PDF with correct /Lang attributes for the right screen-reader behaviour. Bilingual documents — the typical Indian government circular — are detected automatically and handled with per-span language tagging where dominance is mixed.

If your accessibility scope is English-only, this difference does not matter. If your scope includes any meaningful volume of Indian-language content, this difference is the entire comparison.

04 · How each tool verifies compliance

Both tools claim PDF/UA-1 conformance. The difference is whose validator the claim runs through.

CommonLook ships its own validator — the CommonLook Validator product — which runs against PDF/UA and other standards. It is rigorous and the output is widely accepted. You can also run veraPDF separately against CommonLook output, and most output passes cleanly. The customer-facing compliance claim, however, is vendor-validated by default: CommonLook produces a CommonLook-validated PDF.

AccessSure uses veraPDF — the open-source PDF Association reference validator — as the headline score on every output. The number on your compliance certificate is the veraPDF rule pass rate against ISO 14289-1. Anyone with veraPDF installed can re-run the validation and confirm the same number. We did this deliberately: the alternative is asking buyers to trust our own validator's reading, and that asking is the wrong starting point. The certification threshold is set at 90% veraPDF rule pass. Documents below that bar receive an audit report but not a certificate.

This is a positioning choice, not a technical superiority claim. CommonLook's validator is rigorous. veraPDF is also rigorous. The customer-facing question is whose word do you want on the compliance claim — and we have chosen the open-source third party's word over our own.

05 · Pricing — in two currencies and two structures

The pricing models are different shapes, which makes apples-to-apples comparison hard. We have run the numbers both ways.

To make this concrete, three realistic scenarios for an Indian organisation processing PDFs:

Two things to note about this table. First, CommonLook's per-user licence assumes one trained operator can handle the volume — at 10,000 documents a year that operator needs to process 40 documents per working day, which is the high end of realistic throughput for non-trivial content. Second, AccessSure's per-page pricing scales linearly with usage, which is a feature for low-volume buyers and a cost-management concern for very-high-volume buyers — where the enterprise per-document rate kicks in.

06 · Three real scenarios, scored

The right tool depends on what you are actually trying to do. Three scenarios we get asked about most often.

Scenario A: a state government department remediating annual reports

200 documents per year. Most are bilingual (regional language + English). Volume is bursty around the financial year. No dedicated accessibility specialist on staff. Compliance driver is GIGW 3.0 and the impending STQC review.

Recommendation: AccessSure. Operator-led tools require a trained operator the department does not have. Bilingual regional-language content is where AccessSure's pipeline is built and where CommonLook is weakest. Cost of AccessSure for the year: ~₹3,000. Cost of CommonLook plus operator training: ₹1,00,000+ licence plus 2–3 weeks of staff training time. The cost-benefit is not close.

Scenario B: a SEBI-regulated mutual fund publishing English investor disclosures

500 documents per year, mostly English, some include complex financial tables. A small in-house compliance team handles accessibility as part of broader regulatory work. Compliance driver is the August 2023 SEBI accessibility circular and IS 17802.

Recommendation: AccessSure for the volume base case, supplement with ITQCR audit lab for complex tables. CommonLook would handle the complex tables better than AccessSure's current pipeline, but the licence cost only makes sense if the team has time to drive an operator-led tool. For most regulatory accessibility teams who already have ten other compliance hats, AccessSure plus selective lab support is faster.

Scenario C: a US federal contractor producing Section 508 deliverables

Strict Section 508 compliance requirements, English-only content, complex documents (forms, multi-column reports, technical specifications). Dedicated accessibility specialist on staff, certified IAAP-CPACC or similar.

Recommendation: CommonLook, with AccessSure as a secondary tool for high-volume simple documents. The Section 508 procurement environment values established tooling with a decade-plus track record. CommonLook fits that ask. The trained specialist is already in place. AccessSure can still help on the high-volume base case, but it is not the primary tool for this profile.

07 · Who should pick which

Simplified routing, based on the scenarios above plus dozens of evaluation conversations.

08 · Migrating between the two

Because both tools output standard PDFs — there is no proprietary file format on either side — migration is mechanical. The harder part is workflow.

If you are currently a CommonLook customer evaluating AccessSure, the practical move is not "rip and replace." It is "route the easy 80% to AccessSure and reserve CommonLook for the 20% it does better." Configure the operator's queue to receive only the documents flagged as complex by AccessSure's pre-flight analyzer. The operator's hours per week drop dramatically; the licence pays for itself with the residual complex cases.

If you are starting from no tool at all (manually editing in Acrobat Pro, or shipping inaccessible PDFs), AccessSure is the faster on-ramp. You can be processing real documents within ten minutes of signup. No training, no procurement cycle, no operator hiring.

If your compliance driver is specifically US Federal Section 508 and your buyer asks for vendor history, CommonLook's twenty-year track record is the procurement-defensible choice for now. Revisit in eighteen months as AccessSure's Section 508 customer base grows.

09 · Questions buyers ask in evaluation calls

The honest tool choice is whichever lets your team ship accessible documents reliably. For some teams, that is CommonLook. For most Indian compliance teams in 2026, it is AccessSure. The conversation is worth having either way.
