Text with a missing space after punctuation — "Hi.How are you?" instead of "Hi. How are you?" — commonly results from certain export processes, PDF text extraction, or fast typing where the space bar press gets dropped.
This tool detects punctuation marks (periods, commas, exclamation points, question marks, colons, semicolons) immediately followed by a letter with no space, and inserts the missing space, while being careful not to break up things like decimal numbers or abbreviations.
This is a common cleanup step after extracting text from a PDF or scanned document, where spacing between sentences sometimes gets lost in the extraction process, leaving run-together sentences that need this specific fix.

This kind of task shows up constantly in everyday writing, coding, design, and admin work, which is exactly why a dedicated, focused tool saves so much back-and-forth.
A tool that does one job well, without a cluttered interface or unrelated features competing for attention, tends to be faster to use than a heavier all-in-one app.
If you find yourself needing this often, keeping this page open in a tab is usually faster than digging through a bigger software suite's menus.
Because there's no sign-up or installation step, you can jump straight from a search result to a working tool in a couple of seconds.
The interface is intentionally simple, so there's no learning curve — the input goes in, the result comes out, and that's the whole interaction.
Frequently asked questions
Will this add a space inside a decimal number, like 3.14?
No, the tool specifically checks that the character after the punctuation is a letter, not a digit, so decimal numbers like 3.14 are correctly left untouched.
Does this fix spacing before punctuation too, like extra spaces before a comma?
This tool specifically targets missing spaces after punctuation; use a separate cleanup step if you also need to fix extra spacing before punctuation marks.
