InkCheck

Introduction to InkCheck

InkCheck is a browser-based manuscript editor designed specifically for novelists, editors, and self-publishing authors who require precise, non-intrusive editorial feedback. Unlike AI writing assistants that rewrite or rephrase prose, InkCheck analyzes text without altering it—highlighting potential issues while preserving the author’s voice and stylistic intent. It runs entirely client-side with no account, no server communication, and no cloud processing, ensuring full privacy and offline usability.

The tool targets professional and serious amateur writers who have moved beyond basic grammar checking and need deeper structural and stylistic analysis. Its design reflects editorial best practices: flagging patterns rather than prescribing fixes, enabling human judgment at every step, and integrating seamlessly into existing revision workflows—whether for solo drafting, editorial collaboration, or pre-submission polishing.

Key Takeaways

• Runs entirely in the browser with zero data transmission; manuscripts never leave the user’s device
• Supports offline use via a single HTML file; no internet connection required after initial load
• Analyzes 11 distinct issue types across mechanical, stylistic, and repetition categories
• Imports plain text (.txt), Markdown (.md), and PDF files; exports to .txt, .doc, and PDF
• Provides severity scoring (1–5) for all issues, allowing prioritization by impact
• Offers customizable banned and watch word lists that persist across sessions
• Generates structured reports (Editor tier) and supports draft comparison (Pro and Editor tiers)
• Free tier includes full analysis, custom word lists, chapter navigation, and basic export

How InkCheck Works

InkCheck operates in three straightforward steps: load, analyze, and review. Users begin by importing a manuscript file (.txt, .md, or .pdf) or pasting text directly into the editor. Because processing occurs locally using browser-native JavaScript, no content is uploaded or stored externally. Once loaded, users select either a Quick scan (focusing on mechanical issues like double spaces and punctuation errors) or a Standard scan (which adds stylistic and repetition analysis, including passive voice, filler words, adverb overuse, and sentence length).

Issues are highlighted inline and listed in a sidebar with severity scores, categories, and contextual excerpts. Users can filter, sort, and navigate issues by severity, category, or document position. Chapter navigation detects Markdown headings and ALL CAPS titles, enabling rapid movement through long documents. Edits are non-destructive: users approve changes individually or in bulk before exporting.

Core Benefits and Applications

For novelists, InkCheck serves as a consistent first-pass editorial filter—identifying patterns that become invisible after multiple readings, such as passive constructions or repetitive phrasing. Editors use it to generate standardized, printable Editor’s Reports with categorized issue breakdowns, severity-weighted statistics, and author-facing notes—reducing manual note-taking time by up to an hour per manuscript. Self-publishers benefit from cost-effective, repeatable quality control between drafts, catching mechanical oversights and stylistic inconsistencies that undermine reader immersion.

The tool also supports pedagogical use: creative writing instructors recommend it for revision-stage feedback because it avoids prescriptive rewriting and instead surfaces objective patterns for student reflection. All tiers maintain strict data sovereignty, making InkCheck suitable for sensitive or unpublished work—including manuscripts under agent review or contractual confidentiality.
