Catch every spelling error and typo
AI finds only spelling mistakes and typos in your writing. Clean, focused proofreading before you submit anything.
Catch every spelling error and typo
River's Spelling and Typo Checker finds every spelling error and typo in your writing. You paste your text. The AI adds comments highlighting only misspellings and obvious typos. No grammar suggestions, no style feedback, just clean proofreading. Within minutes, you have every error marked for correction. Perfect for writers who need final proofreading before submitting work to agents, editors, contests, or publishers.
Unlike grammar checkers that flag dozens of issues, we focus exclusively on spelling and typos. The AI identifies misspelled words, repeated words, missing words, and obvious keystroke errors. You get targeted, actionable feedback on actual mistakes without being distracted by style preferences or questionable grammar suggestions. Each comment simply identifies the error so you can fix it quickly.
This tool is perfect for all writers who need clean manuscripts before submission. Use it as final pass before querying agents, entering contests, or publishing. Use it on blog posts, essays, or any writing where spelling errors would undermine credibility. Great for catching errors your eyes skip over because you've read the text too many times. The focused feedback finds what you miss.
Why Spelling Errors Kill Credibility
Spelling errors and typos signal carelessness to professional readers. Literary agents reject manuscripts over typos in query letters. Contest judges mark down entries with spelling mistakes. Editors question writer competence when they spot errors in first pages. It's not fair. A few typos don't reflect writing skill or story quality. But they create impression that writer didn't care enough to proofread. In competitive situations, readers look for reasons to reject. Spelling errors give them that reason.
The problem is you can't catch your own typos reliably. Your brain autocorrects as you read. You see the word you meant to write, not the word that's actually there. You read 'form' when you wrote 'from.' You skip over repeated words. You don't notice missing words because your brain fills them in. This is normal human reading. It's why every professional publication uses proofreaders. You need fresh eyes or tools that read exactly what's on the page, not what's supposed to be there.
Different readers have different tolerance for typos. Blog readers might forgive a few in 2,000 words. Literary agents have zero tolerance in query letters. Academic readers expect perfect proofreading. Know your audience's expectations and proofread accordingly. For anything you're sending to gatekeepers (agents, editors, contest judges), the standard is zero errors. Use every tool available. Read backwards sentence by sentence. Have someone else proofread. Use spell-check tools. One typo in a query letter can mean automatic rejection.

Frequently Asked Questions
Will this flag made-up words in fantasy or sci-fi?
Possibly. The AI identifies words not in standard dictionaries. For invented names, places, or fantasy terms, you'll see comments. Just ignore those. The tool helps you catch actual typos versus intentional invented words. If a fantasy name is flagged, you know it's spelled consistently wrong (which you can ignore) versus mistyped (which you should fix). Check flagged words to ensure invented terms are spelled consistently throughout your manuscript.
Does this catch grammar mistakes too?
No, only spelling and obvious typos. This tool won't comment on comma splices, subject-verb agreement, or sentence fragments. If you want grammar feedback, use a grammar checker. This tool serves writers who want clean spelling without grammar suggestions they might disagree with. Many writers prefer to keep their grammar choices and just need spelling help. This is that focused tool.
What about repeated words like 'the the'?
Yes, this tool catches those. Repeated words are obvious typos that spelling checkers often miss because each individual word is spelled correctly. The AI identifies when the same word appears twice in a row, which is almost always an error. These are easy to miss when proofreading yourself because your brain skips over repetition. The tool catches what your eyes miss.
Should I run this before or after grammar checking?
Either way works, but running it last makes sense. If you're doing grammar revision, you might create new typos while rewriting sentences. Run spelling check as your final pass after all other revisions are complete. Think of it as the last step before you consider a manuscript done. Grammar first, style second, spelling last. Catch typos right before you hit send.
Can this replace human proofreading?
It's a powerful tool but not perfect. For critical submissions (agent queries, contest entries, publication manuscripts), use multiple proofreading methods. Run this tool. Use your word processor's spell-check. Have a trusted reader proofread. Read your work backwards sentence by sentence. The more important the submission, the more layers of proofreading you need. This tool catches most errors. Combining methods catches nearly all.
