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.
