StepFun
Six ways to run it from a message.
Drive it by message when you need it, or put it on autopilot.
Text to narrated audio
Forward an email or dictate a paragraph and Notis returns it as natural StepFun speech in an MP3 file.
Change the delivery
Reply "slower, with a small laugh at the end" and Notis regenerates the StepFun audio with that delivery.
Find the right voice
Ask "which voices speak French?" and Notis lists the StepFun built-in voices so you can pick one.
Morning briefing read aloud
Every morning, get your calendar and top emails as a short StepFun audio briefing in the voice you chose.
Scheduled voiceovers
Every Monday Notis reads your new blog post aloud in your cloned StepFun voice and sends you the MP3.
Your voice across tools
Clone your voice from a ten second recording, then voice Google Docs drafts, Notion pages or Slack updates with it.
