Quick guide
Which writing tool do you need?
Most writing chores come down to one of a handful of jobs: hearing your words, capturing speech, comparing drafts, or cleaning up text that was pasted from somewhere else. Find the job below and go straight to the right tool.
| If you want to... | Use | Why it helps |
|---|---|---|
| Proofread a draft by listening to it | Text to Speech | Hearing text read aloud catches missing words and clumsy rhythm that silent reading skips over. |
| Dictate notes instead of typing | Speech to Text | Works best in Chrome or Edge; speak in short phrases and add punctuation as you go. |
| See what changed between two versions | Text Diff Checker | Paste the old and new versions to see every added and removed line highlighted. |
| Fix text pasted in ALL CAPS or the wrong case | Case Converter | Switch between UPPERCASE, lowercase, Title Case, Sentence case and camelCase in one click. |
| Clean up pasted text from a PDF or email | Whitespace Trimmer | Trims stray spaces, collapses extra blank lines, or flattens everything onto one line. |
| Remove repeated rows from a list | Duplicate Line Remover | Useful for email lists, keyword lists and exported data before you import it elsewhere. |
| Spot overused words in an essay or article | Word Frequency Counter | Ranks every word by how often it appears, so repetition is obvious at a glance. |
| Turn a headline into a clean URL | URL Slug Generator | Lowercases, strips punctuation and joins words with hyphens for blog and product URLs. |
| Spell out a code or name clearly over the phone | NATO Phonetic Translator | Converts letters to Alfa, Bravo, Charlie so booking codes and serial numbers are not misheard. |
| Write and check Markdown formatting | Markdown Previewer | Shows the rendered result live beside your Markdown for READMEs, notes and docs. |
Questions
Before you dive in
Are these writing tools free?
Yes. All 19 tools are completely free with no limits and no account required.
Do text to speech and speech to text upload my data?
Both use your browser's built-in Web Speech API rather than a Slaytic Converter server. Speech recognition in some browsers relies on that browser's own cloud service as part of its platform behavior.
Which browsers support speech to text?
Chrome and Edge have the most reliable support. Firefox and Safari have limited or no support at the time of writing.
Where is the word counter?
The full word, character, sentence and paragraph counter lives in the Other category. The Word Frequency Counter here ranks which words you repeat most, which is a different job.
Is the text I paste stored anywhere?
No. Every text tool here processes what you paste inside your browser tab. Nothing is sent to or saved on a Slaytic Converter server.
