A real proofreader, on your own computer
Built-in spelling and grammar checking that runs offline — a word processor's, not a browser squiggle.
Most web-based writing apps leave proofreading to your browser — the same red squiggle you get in any text box. Verkilo ships its own checker, the kind you’d expect from a desktop word processor, and it runs entirely on your computer.
Check when you’re ready
Drafting and proofreading are different jobs, so nothing gets flagged until you ask. Right-click and choose “Check Spelling & Grammar”: misspellings get red underlines, grammar issues blue, and a counter in the footer hops you from one problem to the next.
- Underlines keep up as you edit, and clear when you’re done
- Prefer constant checking? Turn on “Check While Typing” and it never stops
Fix from the right-click menu
Right-click any underline and the suggestions sit at the top of the menu, next to “Ignore” and “Add to Dictionary” — the same muscle memory as every word processor you’ve used.
Nothing leaves your machine. The checker is a deterministic rule engine that works completely offline: no account, no cloud, no AI, and your manuscript stays where it is.
A dictionary that knows your story
An ordinary spellchecker flags every invented name in a fantasy novel. Verkilo already knows yours: character and location names from your Series Bible are recognized automatically, and anything else goes in your personal dictionary once.
- Six English dialects: American, British, Canadian, Australian, New Zealand, and Indian
- Hundreds of rules you can toggle one by one
- Style rules that fight fiction prose — sentence-length nags and the like — are off by default
Common questions
- Does my manuscript get sent anywhere for checking?
No. The checker runs entirely on your computer — no account, no network connection, no cloud service. It works the same with your internet turned off.
- Is this an AI feature?
No. It’s a deterministic rule engine: the same text always gets the same result, and it works with every AI feature in Verkilo switched off.
- What languages does it support?
English only for now, in American, British, Canadian, Australian, New Zealand, and Indian dialects.
- Will it complain about my style?
It’s a proofreader — misspellings, doubled words, agreement, punctuation — not a style coach. The rules that tend to fight fiction prose are off by default, and every rule can be toggled individually.
