AuthentiCast detects piracy for creators — podcast, audiobook, and audio drama protection that catches stolen copies the moment they surface. Register your audio, and we watch for it turning up on YouTube, TikTok, or piracy sites—reposted, re-uploaded under a new name, or AI-cloned in a different voice. Protect your work from theft. Think Copyscape, for audio.
Register once, monitor forever. Every check runs against your own catalog and a database we maintain for you.
Send us your audio (or just a URL). We create a digital signature—just a few hundred bytes, not the file itself—and store it under your own ID so you stay in control.
Any new audio is compared against your catalog and a shared database we monitor from legitimate podcast hosts and archives. You get a match confidence and location, instantly.
We show you the match and confidence level — nothing more. You decide what counts as theft, a remix, or a false alarm. Full transparency, no black box.
Same idea in three media: register what you made, then watch for it turning up somewhere you didn't put it. One account, one integration, one shared database.
Podcasts, audiobooks and audio drama. Our audio detection catches re-uploads even after re-encoding, trimming or volume changes — and dialogue matching catches the same episode re-recorded in a different or AI-cloned voice. We check against your catalog and a shared database of legitimate hosts, plus YouTube and TikTok.
Books, articles and unpublished manuscripts, matched section by section so a stolen chapter is caught even inside a larger work. Unpublished manuscripts are registered as protected originals — we hold digital signatures, never the actual text. Scanned PDFs are automatically converted to text. Detection searches the open web and retail sites for phrases from your work.
Script and dialogue matching, live now. VN scripts are checked section by section — across Ren'Py and JSON formats — which catches reskinned releases that kept the writing intact.
not yet Art and sprite matching are a separate feature and not included yet — a VN whose script is new but art was copied will not be caught.
Power comes from the database—a constantly updated index of what's already out there. We search it continuously, in the background, so you don't have to.
Detects copies even after re-encoding, trimming, or volume changes — catching piracy that filename searches miss.
We automatically re-check every source in our database every few hours. We're actively adding new podcast hosts and archives so nothing slips through.
Searches known file-sharing and torrent sites for your work. Undergoing legal review before launch.
Finds likely reposts of your published work by searching titles and creator names. Text-only search, no access to video or audio files.
Just two API endpoints — one to upload, one to check. Integrate into your upload flow in an afternoon. You control everything with your own API keys.
Every check is metered and shown in your dashboard. Simple monthly plans, no surprise bills — top up with credits if you ever need more.
Every plan has access to the same detection database — no tier gets a smaller index. Prices are per month.

Unpublished manuscripts are registered as protected originals — we store digital signatures only, never the actual text.
It creates a digital signature of your audio — podcasts, audiobooks, audio drama — and tells you when a track shows up elsewhere: re-uploaded under a new name, pirated, or reposted. Think Copyscape, but for audio.
Yes. Register a book, article or unpublished manuscript and we watch for it being copied — the same idea as audio, applied to text. Unpublished manuscripts are always registered as protected originals: we store digital signatures only, never your words, so we can recognise your text without holding it. Books are included with the paid audio plans as a monthly allowance — Growth gives you one book a month, Pro gives you three — and your allowance refreshes each billing cycle. Registering a book uses one of that month's slots; deleting it doesn't give the slot back, but you get a fresh allowance next month. Each book gets 5 years of weekly protection (YouTube, TikTok, and piracy sites). Want more? Buy books separately anytime as one-time purchases (volume pricing is cheaper). Alternatively, our bundle plans include book and VN registrations as a one-time signup bonus alongside monthly audio checks. EPUB, DOCX, PDFs with a text layer and plain text all work; a scanned PDF needs OCR first, which we can enable for you on request.
Visual novels are supported too — register a VN and we watch for it being re-shared, re-uploaded or re-posted. We scan the same places as books: YouTube, TikTok, and known piracy sites. One-time purchase: each registration includes 4 years of weekly protection. The scans happen automatically every week until coverage ends; to get monitoring again, register the VN once more.
No. We compute an acoustic fingerprint — a compact numeric signature a few hundred bytes long — and store that, not your audio. It's enough to recognise a track, but you can't reconstruct the audio from it.
You upload your catalog once (send audio or just a URL). After that, any audio you check is compared against your own catalog and a shared database we maintain — you get a match confidence score and location instantly. We show you the match; you decide what it means (theft, a remix, a false alarm).
A shared database built from legitimate podcast and audiobook hosts (RSS feeds, Archive.org, indie sites) — every customer benefits from the same index. Plus YouTube and TikTok title search to find reposts of your published work. We're also building detection for piracy sites: a search of known file-sharing and torrent domains (in progress, not yet live) and deeper verification on suspicious matches (paused pending legal review) — neither is active yet.
Never. That search looks at public titles, channel names and URLs only — text information, not videos or audio. We never download or analyze media from those platforms.
There's a free plan (500 checks/mo). Beyond that: pay-as-you-go at $4 for 500 checks (prepaid credits, no subscription, they don't expire), or monthly plans from $12. Reach your monthly plan limit and you can top up any time with pay-as-you-go credits — no surprise overage. See pricing for the full breakdown.
