Maskai.co injects a safe transcript into a hidden audio layer that moderation bots read — while your audience hears the original audio, unchanged.
Two layers. One file. Your listeners hear everything. Content moderation sees only what you want.

Understand how our engine splits audio into two independent layers: one for humans, another for AI moderation systems
We map your original audio frequencies to find the optimal injection bands for the target STT models.
The safe transcript is encoded into the identified frequency bands — invisible to the ear, visible to the machine.
The human layer preserves full original audio fidelity with zero perceptible change.
The AI reads the safe transcript layer and transcribes policy-compliant content. Automatic clearance.
Optimized pipeline processes audio in seconds. Upload, process, and download in a single interface.
An intuitive interface anyone can use — no technical skills required
Drop your video or audio file — we support MP4, MOV, MP3, WAV and every major format.
Our engine writes an alternate transcript into a hidden audio layer that only STT algorithms detect.
Grab your processed file and publish. Moderation bots read the safe layer while your audience hears the real deal.

Maskai.co embeds an alternate, harmless audio transcript into a hidden layer of your media file. Human listeners hear the original audio unchanged, while automated speech-to-text systems read the safe layer instead. The result: your creatives pass content moderation on ad platforms.
We inject an alternate audio signal into frequency bands that STT algorithms prioritize. Human perception ignores these bands entirely, so your audience hears zero difference.
No. We preserve 99.7% fidelity of the original waveform. The injected layer sits in frequencies and amplitudes that the human ear cannot distinguish from the original signal.
Any platform that uses automatic speech-to-text for content moderation — including Meta Ads, Google Ads, TikTok Ads, YouTube Ads and programmatic networks.
Most files complete in under 60 seconds. Pro and Business subscribers get priority queue access with even shorter turnaround.
Absolutely — cancel from your dashboard anytime with no penalties. You keep full access until the end of your current billing period.
Your upload counter resets at midnight UTC every day. Unused uploads do not roll over to the next day.
“We were losing $50K/month in wasted ad spend from rejected creatives. After switching to Maskai.co, our team ships campaigns same-day with a 97% first-pass approval rate. The ROI paid for itself in the first week.”

Agency Director
“I have stress-tested every workaround on the market. Nothing touches Maskai.co's dual-layer approach. My team processes 200+ creatives weekly in under an hour with zero manual QA — it is the unfair advantage every media buyer needs.”
