Spellcast Style Checker

Write the way you want. Consistently.

Spellcast Style Checker is an automated style guide checker and formatting assistant for Microsoft Word. It checks your document for style guide consistency, defined term drift, cross-reference errors, and drafting leftovers—so your contracts, briefs, and reports stay polished without taking up hours of manual proofreading.

Key features & checks

• Defined terms & glossary: Audits defined terms for capitalization consistency, terms defined but never used, undefined terms, and surfaces an interactive glossary panel directly in Microsoft Word.
• Typography & spacing: Flags mixed straight vs. smart quotes, inconsistent spacing after full stops, mismatched dash types (en/em dashes), and inconsistent capitalization after colons.
• Page formatting & alignment: Identifies orphan headings separated from their content, inconsistent paragraph alignment, and broken list structures.
• Cross-references & numbers: Highlights unlinked static cross-references, broken clause citations, and discrepancies between spelled-out numbers and their numerals (e.g., "clause 5 (six)").
• Drafting leftovers: Performs a final sweep for unclosed brackets, [insert] placeholders, ___ blank lines, and TK markers before you send the document.

Why choose Spellcast?

• Document-first style detection: Spellcast automatically detects your document's established conventions (e.g., smart quotes vs. straight quotes) and flags exceptions without requiring complex upfront configuration.
• 100% Private & Local Processing: Your document text never leaves your environment. All checks execute locally inside the Word task pane sandbox.
• No subscription or vendor lock-in: Free and open utility built and maintained as a public good.
