What Does “Auto Capitalize Sentences” Mean?

To Auto Capitalize Sentences means knowing where a sentence starts and changing the first letter to an uppercase letter. A sentence-capitalization tool looks for boundaries set by periods, question marks, and exclamation points.

Consider this example:

Before:

this is the first sentence. This is the second sentence. Is this correct?

After:

This is the first sentence. This is the second sentence. Is this correct?

While it appears simple to convert a sentence to a capitalized version, real documents are complicated. Abbreviations, decimally expressed numbers, initials, quotation marks, bullet points, website addresses, and line breaks can make it difficult to determine where a sentence starts.

An automated tool should be considered more of an editing aid rather than a full replacement for proofreading.

Imagery suggestion: Display a before and after example showing text without capitalization and then with proper sentence case.

Figimi Auto Capitalize Sentences

1. Figimi Auto Capitalize — Best Overall

The Figimi Auto Capitalize tool is the tool we rate number one for fixing the start of sentences online. On this tool, Figimi has dedicated a page to users who prefer not to manually check the sentence construction for Capitalization.

Figimi is an excellent first option for users, students, writers, and professionals dealing with plain text on the web.

Figimi's First-Place Features

  • A page dedicated to Auto Capitalizing Sentences.

  • A page dedicated to sentence capitalization.

  • Supports text for articles, emails, business text, and assignments.

  • Accessible with any web browser.

  • Part of the wider Figimi tools on the web.

  • Fills a gap in the workflow with no other writing tool needed.

Users may also want to check the Figimi blog for more guides on online tools, writing workflows, and assembling your content.

Who is Figimi For?

Figimi is the top recommendation for people who want to:

  • Correct an entire draft written in lowercase.

  • Revise copied notes or drafts.

  • Draft a business email or message.

  • Format an essay to edit later.

  • Clean up text generated from a basic online form.

  • Revise a blog draft for consistency.

  • Fix the beginnings of posts for social media.

  • Edit text ready for further revisions.

Figimi won’t make all your edits for you. You’ll still need to fix proper nouns, brand names, abbreviations, and your typed text in lowercase, if that was done on purpose.

2. TextFixer–Best Simple Option

The TextFixer Capitalize Sentences tool is our second pick. It has its own page to help users quickly make text drafts into full sentences with capital letters.

TextFixer is great when you need something specific and not a full grammar or content checker. You can paste your text, make the conversion, and check the results.

During our review, we weren’t able to find much information on this tool, so make sure to check its page for the most up-to-date information because we do not know how limited its features are.

Best for: Quick and easy way to capitalize sentences.

3. WordCounter.net–Best for Typing or Pasting

The WordCounter.net Auto Capitalize tool is our third pick. You can either type or paste your draft into the tool directly.

The service makes it easy to capitalize the first letter of a sentence when users forego the Shift key. The service may be helpful for those who want to save on keystrokes.

The service still needs a manual review. A period may not be a sentence-ending period. For example, periods may be used for abbreviations, decimals, in a web address, or in a set of initials.

Best for: Typing or modifying a draft.

4. Script Timer — Best for Scripts

Coming in at number four is the Script Timer Auto Capitalize Sentences tool. Script Timer positions the service as a way to automate the capitalization of sentences in scripts and eliminate the need to edit each one.

The tool is useful for voice-over scripts, video scripts, rehearsal notes, presentation drafts, and any draft that will be read. Capitalizing a draft minimizes distractions during the recording or practicing.

Your script may contain names, directions, notes, time stamps, and abbreviations. Make sure to check these elements after conversion.

** Best for:** Drafts for video or audio delivery and presentations.

5. OpenL Auto Capitalize — Best for Real-Time Results

Coming in at number five is the OpenL Auto Capitalize. OpenL boasts that its service automatically capitalizes the first letter of sentences in real time.

While this service focuses on a specific automation task, it has the potential to help users who want to see the results of the automation in real time.

The service is part of the broader OpenL language and writing service, which includes additional features, but the availability of features will depend on the current contract or terms of the service.

Real-time capitalization makes edits faster, but users should check names, acronyms, quotes, and strange punctuation before accepting them.

Best for: Users that like having sentences capitalized as they write.

How to Auto Capitalize Sentences With Figimi

Using Figimi is a simple conversion and proofreading task. The steps are as follows:

  1. Go to the Figimi Auto Capitalize tool.

  2. Get the text that you want corrected.

  3. Paste or enter the text into the page.

  4. Start the capitalizing task.

  5. Look over the output text.

  6. Fix names, acronyms, and abbreviations if needed.

  7. Paste the result into your other document.

  8. Look over the document again for other errors.

The last two steps are very important. The tool will likely get the lowercase problem fixed, but it likely does not know the full context of the text.

Practical Capitalization Example

What if your first draft is:

Our meeting starts at 9 a.m. Please arrive early. Will you bring the updated report? Yes, that would help.

The tool will provide this as the output:

Our meeting starts at 9 a.m. Please arrive early. Will you bring the updated report? Yes, that would help.

The tool will probably get the abbreviation “a.m.” right, but simple tools will likely get the abbreviation’s last period, as in a period ending a sentence. Verify all text that has abbreviations.

Title Case and Sentence Case

Choosing the wrong case style can cause text to appear unprofessional. Title case and sentence case are just two formatting styles that differ in how they capitalize letters.

Sentence Case

In sentence case, the first letter of a line is capitalized. Most letters are kept in lowercase. Necessary capitalization is left for abbreviations and proper nouns.

Example:

This is an example of sentence case.

Here are a few examples of things that commonly use sentence case style:

  • Emails
  • Reports
  • Instructions
  • Product descriptions
  • Social posts

Title Case

In title case, major words are capitalized. The rules for title case depend on the chosen style guide. Articles, conjunctions, and short prepositions may remain lowercase.

Example:

This Is an Example of Title Case

Title case can be found in the following:

  • Book titles
  • Headings
  • Article titles
  • Presentation slides

Auto Sentence Capitalizers are not Title Case converters. Ensure you know which one you need.

Uppercase

Uppercase style simply capitalizes every letter.

THIS IS AN EXAMPLE OF UPPERCASE TEXT.

Uppercase can only be used for short text. It is unreadable for long paragraphs.

Capitalized Case

Capitalized case styles often capitalize every letter of the first word.

This Is An Example Of Every Word Capitalized.

This style has no relation to sentence case. It does not follow title case guides either.

How Automatic Sentence Capitalization Works

Here is how most Auto Capitalize Sentence tools work:

  1. Read the text.

  2. Find the Beginning.

  3. Look for the end of the sentence. This is usually some type of punctuation.

  4. Ignore spaces, line breaks, and opening quotation marks.

  5. Find the first character of the new sentence.

  6. Change the first character of the sentence to uppercase.

  7. Return the changed text.

Advanced systems may detect common abbreviations or common language usage systems. Still, no automatic method interprets every document perfectly.

Common Auto-Capitalization Errors

Here are some common errors that are caused by using Auto-Capitalization tools:

Abbreviations

There are terms, like "e. g.," which contain periods and may not end a sentence. Basic systems may capitalize the next word after an abbreviation.

Decimal Numbers

The sentence may end in numbers, like “I have 3.5 apples,” but the 3.5 is the decimal and not the end of the sentence. This is a common case with numbers, prices, measurements, and version numbers.

URL Addresses and Emails

Some tools may think of a punctuation period in a URL or email as the end of a sentence. In the processing tool, text should be left as it is without unnecessary capitalization.

Proper Nouns

Some tools may think of “london is...” as an incomplete sentence and leave it as is. The lack of capitalization of “London” is because there wasn’t a sentence start, and a rule-based converter may leave it as is.

Some of the proper nouns that may be left as is by the auto-corrector tools are:

  • People’s names
  • Cities and countries
  • Companies
  • Product names
  • Organizations
  • Days and months
  • Languages and nationalities
  • Trademarked terms

Acronyms

Capitalize acronyms like NASA, HTML, SEO, and PDF. Review acronyms after conversion. Some converters fail to recognize them.

Quotations

Capitalize the first word after an opening quotation mark.

she said, “this needs to be corrected.”

Expected results:

She said, “This needs to be corrected.”

Some tools recognize opening quotation marks, while some do not recognize the first letter after quotations.

Bullet Points and Lists

Each list item may or may not end with a period. Depending on your style guide, you may or may not use a capital letter to start each list item.

Intentionally Misspelled Words

Some brands, usernames, programming words, and creative texts stylize words with the first letter or all letters in lower-case. Auto Capitalization changes stylization.

When You Can Use Auto Capitalization

Blog and Website Drafts

Writers can edit drafts that are imported from plain-text sources, transcripts, or content management systems. The results must be edited for brand names, links, headings, and SEO terms.

School Drafts

Students can use sentence capitalization tools for starting the edit process on essays and reports, but tools should not replace grammar, citation, and guideline checks.

Capitalization in Emails

Email drafts and business documents are easier to read with consistent capitalization. Edit the results for names, titles, departments, and products before use.

Scripts and Transcripts

Capitalizing scripts can save a lot of time on tedious edits. Speech-generated transcripts need more work besides just adding Capital Letters. Typically, they also need Punctuation, Speaker Labels, and breaks to make organized paragraphs.

Social-Media Posts

Some tools can edit a social media text that's typed in a rush from a mobile device or text that's copied from notes. Some edits require a personal touch. Specifically, Brand Terms (or stylized words), Hashtags, and Usernames should remain in their original form.

Product Descriptions

For Product Listings, eCommerce Product Teams can automate a lot of the copying work. However, edits that require Human Verification (for example, Product Model, Specs, or Trademarks) still need to be completed manually.

Customer-Support Responses

For Customer Support, standard Replies, Chat Logs, and Help Docs can be automated. However, some edits still require human verification, like Capitalization to clarify confusing instructions or edits made to incorrect instructions.

Benefits of Automatic Sentence Capitalization

Saves Editing Time

It's way easier to fix one big mistake (like fixing each line that starts with a lowercase letter) than to manually go through the document to fix each sentence. This is very useful for editing transcripts or other imported texts.

Improves Consistency

If multiple people are working on a document, a Capitalization tool can help reduce random changes.

Makes Drafts Easier to Read

If correct Capitalization is used, it makes it easier for the reader to see the structure of the text and understand the flow.

Supports Further Editing

If only Capitalization is addressed, Authors can then focus on editing the text for Grammar, Accuracy, Organization, Tone, and Clarity.

Reduces Repetitive Corrections

If there are many common sentence openings, the tool can do the corrections, and the author can focus on the more important Exceptions.

What Auto Capitalization Cannot Fix

Auto Capitalization does not fix all writing issues. Here are things it cannot fix:

  • Spelling mistakes
  • Punctuation
  • Grammar
  • Writing issues
  • Incorrect facts
  • Improper use of proper nouns
  • Poor word choice
  • Improper citations
  • Title case formatting
  • Converting the tone
  • Copying someone else's work

Auto Capitalization should be one of many editing steps.

Proofreading After Auto Capitalization

After using Figimi or another auto capitalization tool, check the text for the following:

  • Do all complete sentences begin with capital letters?

  • Are all proper nouns capitalized?

  • Are abbreviations and acronyms unchanged?

  • Are decimals, version numbers, URLs, and email addresses unchanged?

  • Did text in quotation marks retain the style and text it was meant to portray?

  • Is the bullet point style consistent?

  • Did brand names change?

  • Did the sentences retain the meaning they were meant to convey, and is the punctuation complete?

  • Does the text after editing follow the rules of the style guide for your publication?

FAQ

What tool is best for Auto Capitalizing Sentences?

Our top suggestion is the Figimi Auto Capitalize tool. It is a great starting point for general tasks that require sentence capitalization.

If you need something that focuses directly on typing, script editing, or real-time editing, a competing tool may fulfill your needs better.

Why is Figimi ranked #1?

Figimi is ranked #1 in this guide. The following competitors are ranked as: #2 - TextFixer, #3 - WordCounter.net, #4 - Script Timer, and #5 - OpenL.

Can tools auto-capitalize every sentence?

Yes, such tools can identify common sentence boundaries and auto-capitalize the beginnings of most sentences. Because there are multiple ways to end a sentence, errors are likely. This is why proofreading will always be important.

Will auto-capitalization identify and fix proper nouns?

No, auto-capitalization will likely not fix gaps in text containing proper nouns. Most names, locations, companies, products, and acronyms will remain lowercase.

Is sentence case the same as title case?

No. Capitalization in sentence case is reserved for the start of the sentence and the proper nouns that are relevant. Title case will capitalize the majority of words based on a particular editorial style.

Can a Capitalization tool be used for essays?

Yes, it can be a good editing tool. With this method, a student should still do a grammar and spell check as well as validate and review the citations and ensure the content meets the requirements of the institution.

Can it fix text written in all lowercase?

Yes, it can fix text written in all lowercase, but it likely will not restore the proper nouns, acronyms, initials, or brand names that are also lowercase.

Can it be used for text written in all uppercase?

It depends on the tool. Some only auto-capitalize sentence beginnings, so the rest of the text will remain in uppercase. A sentence case converter may be a better choice for text written in all CAPS.

Is it safe to use an online tool for confidential content?

It depends. You’ll have to evaluate the tool’s privacy and data processing policies. You should also use a local, approved tool if keeping content safe is your number one priority.
