Vimeo Alternative with AI Protection | sinima.

Host video with AI training opt-out signals, signed C2PA provenance, and ownership certificates per upload. Free 10GB, hard-limit pricing.

Signed C2PA credentials, AI training opt-out signals, and an ownership certificate on every upload — so your work stays yours when crawlers come knocking.

Opt-out signals that crawlers actually read

sinima. emits standardized opt-out signals (TDM Reservation Protocol, robots.txt directives, X-Robots-Tag headers) on every public asset. Crawlers that respect the standards skip your work. The signals are signed, so removing them breaks the signature.

Proof your work was here first

When AI-generated knock-offs surface, the question is always "who can prove they made it first?". sinima. answers it with a publicly verifiable ownership certificate timestamped to your upload — independent of any platform.

Frequently asked questions

Does sinima. block AI scrapers?

We emit the strongest standardized opt-out signals available (TDM Reservation Protocol, robots, X-Robots-Tag) and refuse known scraping user-agents at the edge. Bad actors still exist — but you have signed evidence they ignored your opt-out.

Do you train any AI on my content?

No. sinima. never uses customer content to train models. Your catalogue is private by default.

What is an HNST certificate?

A cryptographic ownership record tied to your account and timestamped to the moment of upload. Each certificate has a public verify URL you can share with anyone.
