What CPAs are saying

Chad Anaya
Partner, Farber Hass Hurley LLP

"We had a complex equity raise with a very unique situation. I went to Quillon, it gave me all the references immediately — that alone saved us hours of combing through documents."

Stacy Starmer
VP Accounting Howard Hughes Communities

As a Real Estate Company with a high volume of leases, Quillon has helped us standardize our technical accounting reviews by reading through lengthy and complex lease language to efficiently conclude on our accounting treatment.

Ankit Sharma
Senior Director, Technical Accounting, Innovaccer

"Every new business launch, non-standard deal structure, or M&A transaction brings accounting questions that lack easy answers. Quillon has compressed our technical research cycle dramatically without compromising rigor."

Problem

We didn't start in accounting — we found the problem when a San Francisco consulting firm told us that technical accountants had no AI tools built for them. Not one. So we embedded with practitioners: consultants, technical accounting directors, SEC reporting managers.

The team behind Quillon

Frequently asked questions

What is Quillon?

Quillon is an AI platform built specifically for technical accounting and financial reporting professionals. It helps teams research accounting standards, search and benchmark SEC filings, read contracts, execute checklists, and draft audit-ready memos — with every claim traceable to the exact source paragraph.

Who is Quillon for?

Quillon is used by Technical Accounting Directors and Managers, SEC Reporting Managers, Controllers, and accounting consultants — anyone who works with complex US GAAP or IFRS questions, SEC filings, or audit-sensitive deliverables.

How is Quillon different from general-purpose AI?

General-purpose AI models are not connected to accounting standards or EDGAR. They hallucinate citations, mix up frameworks (e.g., IFRS vs. US GAAP), and can't provide source-level traceability. Quillon is grounded in the actual codification and real SEC filings — every answer links to the exact source paragraph.

How is Quillon different from traditional SEC filing search tools?

Traditional tools rely on keyword-based search with complex filters — one wrong keyword or missed filter and you get irrelevant results. Quillon lets you search EDGAR in plain English. The AI identifies the right filters automatically. Quillon also offers built-in peer benchmarking tables, contract reading, checklist execution, and a native document editor for drafting — capabilities traditional search tools don't provide.

Can I trust Quillon's answers?

Every claim in Quillon's output links to the exact paragraph in the source material — whether that's an ASC codification section, an IFRS standard, or an SEC filing. You can click any sentence to see the highlighted source. The AI only draws from sources you select — official standards, firm handbooks, or EDGAR filings. No hallucinated citations, no framework mixing.

Can I upload confidential contracts and SEC materials?

Yes. Quillon is designed for teams working with audit-sensitive materials. Your data is isolated, encrypted, and never used for model training. Full contract upload and workspace functionality is available on the paid plan — the free trial lets you explore research capabilities immediately.

Do you provide or distribute third-party accounting materials?

No. Quillon operates on a bring-your-own-content model. Any third-party materials shown on our website or in demos are for illustrative purposes only and are not included with your subscription. Users are responsible for ensuring they have the right to upload and use any third-party content on the platform. Public SEC EDGAR filings are the exception — these are built into the platform.

Is my data secure?

Yes. Quillon is SOC 2 compliant with independently audited security controls. All data is encrypted at rest with AES-256 and in transit via TLS, stored in a segregated environment. We never use customer data to train AI models. Security documentation is available for your procurement team on request.

How do I get started?

You can sign up and start using Quillon in under two minutes. No demo required, no implementation period. Create an account, ask your first question, and see traceable results immediately.

What standards and filings does Quillon cover?

Quillon covers the full ASC codification (US GAAP) and IFRS standards, including IAS, IFRIC, and SIC interpretations. On the SEC side, Quillon searches 10-K and 10-Q filings across EDGAR, with comment letters, 8-K, 20-F, S-1, and 6-K filings being added.
