InkCheck is a manuscript editor designed specifically for serious novelists, editors, and self-publishers who want to improve the quality of their writing without compromising their voice. Unlike traditional writing tools that attempt to rewrite or suggest changes, InkCheck focuses on identifying specific issues in your prose so you can make informed decisions about what to fix. It runs entirely in your browser, requires no account, and ensures your manuscript never leaves your device — offering a powerful yet non-intrusive editorial tool.
The core editor is free to use, with Pro and Editor tiers unlocking advanced features like export options, comparison tools, and printable reports. InkCheck checks for 11 types of issues including passive voice, filler words, repetition patterns, dialogue density, and punctuation inconsistencies. It supports offline use and works with multiple file formats such as .txt, .md, and .pdf. Whether you're a writer refining your first draft or an editor preparing a report for a client, InkCheck offers a streamlined and privacy-first approach to manuscript editing.
