Your prose,
unflinchingly edited.
Catches what spell check misses.
Flags passive voice, filler, repetition, and broken punctuation. You decide what to fix. Nothing gets rewritten without your say.
No suggestions. No rewrites. No second-guessing your voice.
No account. No server. Your manuscript stays on your machine — always.
Built for writers
who mean it
Not a grammar checker. Not an AI rewriter. A sharp editorial eye you control.
Novelists
You've read the draft four times. You've stopped seeing the passive constructions, the filler, the sentence that somehow reached 58 words. Inkcheck still sees them.
Editors
Load a client's manuscript, run the analysis, generate a printable report. Every issue logged, categorised, severity-scored — ready to discuss. The first pass done in minutes, not hours.
Self-publishers
No budget for a copy editor on every pass. Inkcheck won't replace a human eye — but it will catch the things that make a reader stop.
Three steps to
cleaner copy
No setup. No account. Open the editor, drop in your manuscript, and go.
Load your manuscript
Drop in a .txt, .md, or .pdf — or paste directly. Nothing leaves your machine.
Run the analysis
Choose Quick (mechanical fixes only) or Standard (full prose check). Issues ranked by severity, highlighted inline.
Fix, approve, export
Work through issues at your own pace. Approve fixes individually or in bulk. Export as .txt, .doc, or PDF.
Everything an editor
actually needs
Built for real editorial workflows — not just grammar checking.
Deep prose analysis
11 check types covering mechanical errors, style issues, and repetition. Standard scan catches passive voice, adverb overuse, filler words, and more.
Quick + Standard scanEditor's Report
Generate a polished, printable report with manuscript stats, issue breakdown by category, and a personal note to the author.

you stop seeing
Issues ranked by severity
Every issue gets a severity score from 1–5. Focus on what matters — filter by category, sort by severity, or work through in document order.
From writers who
stopped guessing
Early users across fiction, editorial, and self-publishing workflows.
"I've used Grammarly, ProWritingAid, and a dozen others. Inkcheck is the first one that doesn't try to turn my sentences into something that sounds like a corporate memo. It just shows you the problems and shuts up."
"My client manuscripts go through Inkcheck before I read a single page. The first-pass report saves me an hour of notes on every project. The Editor tier pays for itself on the first manuscript."
"I self-published my debut thriller last year and couldn't afford a proper copyedit. Inkcheck caught 340 issues my own read-through missed — double spaces, passive constructions, filler words I'd gone blind to. Worth every cent."
"The privacy thing matters more than people realise. I was querying agents — there was no way I was uploading my manuscript to some server. Inkcheck runs locally and I don't have to think about it."
"I teach creative writing and recommend this to all my students at the revision stage. It's the clearest, least-opinionated feedback tool I've found. No house style creep, no suggestions that homogenise their voice."
"I run every chapter through it before my writing group meets. The severity scoring is genuinely smart — a double space and a full paragraph of passive voice don't get the same weight. That alone puts it ahead of everything else I've tried."
"I have rewritten — often several times — every word I have ever published."

For working writers & editors
The free tier is generous.
The paid tiers are worth it.
If you're editing client manuscripts, the Editor's Report alone saves you an hour of note-taking per project. If you're on your third draft and losing track of changes, Snapshots and Compare Drafts pay for themselves on the first chapter.
