Check spelling and typos in pitch materials
Paste your pitch, update or website copy. Get every spelling error, typo and confused word marked in place, with the correction beside it.
River's Spelling & Typos Checker finds errors that damage your startup's credibility. You paste your pitch deck, investor update, or content, and the AI identifies every spelling error, common typos, grammar mistakes, incorrect word usage (their/there, its/it's), capitalization errors, and suggests corrections. Whether finalizing a pitch deck or sending investor updates, eliminating errors shows professionalism and attention to detail that investors notice.
Unlike basic spell checkers, we understand startup context and catch errors others miss. The AI identifies commonly confused words in context (affect/effect, complement/compliment), finds typos that are valid words but wrong (form/from), catches startup-specific terminology errors, and maintains focus on errors that specifically hurt professional credibility. You get comprehensive proofreading that catches everything before investors see it.
This tool is perfect for founders finalizing high-stakes materials, anyone who writes quickly and misses their own typos, teams before sending important communications, or founders whose first language isn't English. If you've ever sent something with an embarrassing typo, this tool helps. Use it before every investor email, pitch deck share, or website update to ensure zero errors.
Why Typos and Spelling Errors Hurt Credibility
Errors signal carelessness and undermine credibility. When investors see typos in pitch decks, they question your attention to detail. If you can't proofread a 15-slide deck, can you execute a complex business? Spelling errors are unforced errors. They're avoidable with careful review. One typo might slide by. Multiple errors make you look unprofessional. Investors notice. Zero tolerance for errors in high-stakes materials. Proofread everything.
Certain errors are particularly damaging. Misspelling your own company name (happens), mixing up their/there/they're (looks careless), typos in the title or opening slide (kills first impression), errors in numbers or metrics (destroys trust), or consistent mistakes throughout (shows no proofreading). Fresh eyes catch errors you miss. Have someone else review. Use tools. Read backwards. Whatever it takes. No typos should survive to investor eyes.

Common questions
Will this catch errors that basic spell checkers miss?
Yes. Basic spell checkers miss: (1) Valid words used incorrectly ('from' when you meant 'form'), (2) Context errors ('their' vs 'there' based on sentence), (3) Commonly confused words ('affect' vs 'effect'), (4) Capitalization errors in proper nouns, (5) Missing words that make sentences unclear. We check context and meaning, not just whether words exist in dictionary. We catch more because we understand what you're trying to say.
What about industry jargon or technical terms it might not know?
We understand startup and tech terminology. SaaS, MRR, ARR, CAC, LTV, API, etc. are all recognized. If we flag a specialized term, you can verify it's spelled correctly for your industry. Add company-specific terms (your product names, feature names) to your style guide. But if we flag something, at least double-check. Often what looks like jargon is actually a typo. Trust the tool but verify specialized terms.
How important is perfect spelling for investor materials really?
Critical. Investors judge everything. Typos in pitch decks signal: (1) carelessness, (2) lack of attention to detail, (3) disrespect for their time, (4) poor execution ability. Harsh but true. One typo might be forgiven. Multiple errors become a pattern. In a competitive fundraising environment, polish matters. Investors use any signal to filter. Don't give them a reason to pass. Zero typos should be non-negotiable for pitch decks, investor updates, and first emails.
Should I have a human proofread after using this tool?
Yes, for highest-stakes materials. It catches most errors, but a final human read still adds polish. Ideal process: (1) Use this tool to catch most errors, (2) Have co-founder or advisor read through, (3) Read aloud yourself (you'll catch things). Multiple passes with different methods catches everything. For pitch decks going to investors, board decks, or press releases, human + tool is best. For less critical materials, tool alone is usually sufficient.
What are the most common errors founders make?
Top 5: (1) Their/there/they're confusion, (2) Its/it's mixing, (3) Typos from fast typing (form/from, the/then), (4) Missing words that make sentences unclear, (5) Inconsistent capitalization. Also common: affect/effect, complement/compliment, principle/principal. These are all avoidable. Learn the rules once. Use tools. Proofread carefully. No excuse for these errors in investor-facing materials.
