Chrona Pro is now on the Microsoft Marketplace.

The problem

Stop paying contractors to format tables the week before submission.

Most regulatory writers at small biotechs pay someone to clean up document formatting before every submission — tables that need to meet FDA Technical Conformance Guide standards, cover letters that keep getting sent back, styles that drift across contributors. It is the most expensive, most avoidable problem in the stack.

"The cost they offset was a contractor."

Chrona Pro handles it. It runs inside your existing Word workflow, reads your document as you write, and tells you exactly what needs fixing before submission, not after the IR.

What it does

Three things that matter before every filing.

Six checks and tools, all running inside Word's sandbox. Your document content never leaves Word.

Cover letter validator

All four required elements per FDA Tech Guide §4 — contacts, regulatory description, submission size, and AV software name and version. Checked in under a second.

IND table formatting

Tables formatted to FDA submission standards — borders, header rows, font sizes, cell padding, caption placement — in one click. Across the whole document or one table at a time.

Custom rules

Describe a check in plain language, get a taskpane button. Terminology enforcement, scan rules, search rules — your organization's standards, applied automatically.

IND section headings

Browse and insert CTD section headings from the taskpane. Numbered heading hierarchy applied automatically.

Reviewer's guide linter

Structural checks for outline format, hyperlink count, PED table presence, and duplicate TOC content — the most common reviewer's guide failure modes.

Nothing leaves your document

Every check runs in Word's sandbox. Findings are yours to act on. Chrona Pro never modifies your content without your explicit action.
