About Inkcheck
Built for writers.
Not for algorithms.
Inkcheck was built out of frustration with tools that treat your prose as a problem to be solved by a machine — and a belief that the best editing tool is one that shows you the issues and then gets out of the way.
The problem with most editing tools
Most writing tools today want to rewrite your sentences. They'll suggest rephrasing your passive constructions, replacing your word choices with something "clearer," and restructuring your paragraphs for readability. The result is prose that sounds like it was written by a committee.
That's a problem if your voice is the thing you've spent years developing. A sentence that reads as "too long" to an algorithm might be doing deliberate work — building tension, creating rhythm, holding a moment. Grammarly doesn't know that. Neither does any AI.
Inkcheck doesn't rewrite anything. It shows you where the problems are — double spaces, passive constructions, overused filler words, weak verbs, clichés — and it lets you decide what to do with each one. Approve a fix. Reject it. Edit it yourself. Move on. The prose stays yours.
Why offline-first?
When you're working on a manuscript — especially one you're planning to query or publish — uploading it to a third-party server is a real concern. Terms of service change. Data gets used for training. Breaches happen. And for writers under NDA, or on submission to agents, or just protective of their work, the question of where their text goes matters.
Inkcheck is a single HTML file that runs in your browser. When you paste your manuscript, it goes into your browser's memory — not to a server. There's no API call, no upload, no account. You can download the file to your desktop and use it with no internet connection at all.
This is a design choice, not a limitation. It would be easier to build a server-side tool. Offline-first takes more effort. It's worth it because your work deserves that kind of respect.
"The best editing tool is one that shows you exactly what needs attention — and then trusts you to be the writer."

What we believe
Voice is sacred
Every suggestion Inkcheck makes is advisory. Nothing is changed without your approval. Your voice is not a bug to fix — it's the whole point.
Privacy by design
Your manuscript never leaves your machine. Not because we say so in a terms of service — because the architecture makes it technically impossible.
Honest severity
A double space and an overlong paragraph are not the same problem. Every issue is scored so you can prioritise what actually matters in your specific manuscript.
No AI rewrites
There is no language model in Inkcheck. Every check is a deterministic rule written by a human who read too much about craft editing.
Free forever
The core editor will always be free. All 11 checks, unlimited manuscript length, no account required. The paid tiers unlock workflow features — not the analysis itself.
Built to last
A single HTML file with no dependencies that require a server. It will work in ten years the same way it works today. You could bookmark it and come back in 2035.
