AttestWork vs CannyECM

AttestWork is a web workspace for audit, review, compilation, preparation, agreed-upon procedures, and examination engagements. It imports trial balances and general ledgers, compares account balances, and surfaces exceptions. Document processing extracts text and structured fields from scanned PDFs, images, and ledger exports. Teams can search indexed engagement files, including OCR-processed PDFs, and an assistant can draft procedure documentation and workpaper tables using engagement context and files. Firms can connect AI clients such as Claude, ChatGPT, Gemini Spark, or another MCP client through an OAuth-secured connection. The workspace tracks prepared-by-client requests and can link client responses to the relevant request and procedure. Preparers and reviewers must sign off, and editing resets the affected sign-off tier. WorkpaperOS says it does not train its own models on customer work; files are kept in private buckets with short-lived signed links. A five-day trial costs nothing, with no card required. Professional is $57.50 a month for three months, then 115 USD per month; Premium is $92.50 a month for three months, then 185 USD per month.
