Key Benefits
Zero recording required
No microphone, no soundproofing, no takes. Generate professional-grade audio from a single text prompt.
Prompt-driven — not just TTS
Unlike basic text-to-speech, FluxNote's prompt-to-audio understands context, tone, and intent. The output matches your brief, not just your words.
Auto-synced to video
Generated audio is automatically timed and synced with your video footage, captions, and music — no manual editing needed.
Ad-optimised audio
Voiceovers are generated with ad pacing in mind — strong hooks in the first 3 seconds, clear CTAs at the end, natural pauses throughout.
What is prompt to audio?
Prompt to audio is a new category of AI generation where you describe the audio you want — the content, tone, style, and purpose — and the AI produces it. It goes beyond traditional text-to-speech (which simply reads your words aloud) by understanding your intent and generating audio optimised for your specific use case.
With FluxNote's prompt-to-audio, you might type: 'Upbeat 30-second voiceover for a coffee brand targeting office workers. Warm, friendly tone. End with a strong CTA to visit the website.' The AI writes the script, selects the right voice, and generates the audio — already timed for a 30-second slot.
This matters because the difference between a voiceover that converts and one that doesn't is almost never the voice itself — it's the script, the pacing, and the hook. Prompt-to-audio handles all three.

Prompt to audio vs traditional text-to-speech
Traditional text-to-speech tools like Amazon Polly or Google TTS take the text you write and read it back in a chosen voice. The quality of the audio depends entirely on the quality of your script — and you have to write that script yourself.
FluxNote's prompt-to-audio is different in three key ways:
- 1You describe, AI writes — You don't write the script. You describe what you want, and the AI generates an optimised script for your use case.
- 2Context-aware generation — The AI understands the difference between a 30-second ad voiceover and a 3-minute explainer narration. It adjusts pacing, sentence length, and structure accordingly.
- 3Ad-native by default — Every voiceover generated for advertising purposes follows proven ad copywriting principles: hook first, benefits second, social proof third, CTA last.
The result is audio that sounds like it was written by a copywriter and recorded by a voice actor — generated from a single prompt in under 10 seconds.
