Is there a file-size or length limit for videos?

No file-size limit — you submit a public URL and we fetch the video, so multi-GB files are fine. Duration is capped at 10 minutes per video on the free tier and 4 hours on paid tiers. Every video bills at most 20 minutes regardless of length.

What content does SafeReel retain?

Never your media. Image bytes live only in request memory; video frames are deleted within minutes of the verdict. We retain verdicts, quota counters, and non-reversible content fingerprints (hashes).

What exactly does the classifier detect?

It flags pornographic content. Non-explicit nudity, swimwear, and medical or artistic contexts are out of scope. SafeReel does not offer CSAM detection and makes no age determinations.

Scan video by URL — no upload, no file-size limit, multi-GB files welcome — for €0.02 a minute. You give us a URL, we give you a verdict. Published accuracy, your content never retained. 1,000 image checks/month free.

Official SDKs for Node.js, Python, and Go — image checks, video polling, webhook verification, and retries out of the box.

How it works

Submit a URL. POST any public http(s) link — your CDN, S3, a direct file. You never upload bytes, so file size doesn't matter.
We analyze the full video. Frames are sampled across the entire duration — fragmented MP4s and corrupt indexes included — and scored by the production classifier.
Get the verdict. Poll the job or receive a signed webhook: clean or nsfw, with frame counts and duration. Free tier covers videos up to 10 minutes; paid tiers up to 4 hours.

Image detection, too

POST raw JPEG, PNG, or WebP bytes (up to 10MB) and get a synchronous verdict in ~150–250ms. Bytes are processed in memory and never stored. Repeat submissions of the same image return instantly from cache — and cached checks are never billed. 1,000 image checks/month free; pay-as-you-go is €0.50 per 1,000 beyond that.

What SafeReel detects — and what it doesn't

In scope: pornographic content in video and images. Measured behavior for borderline categories is published in the accuracy report.
Out of scope: non-explicit nudity, swimwear, and medical or artistic contexts.
Not offered: CSAM detection and age determination. We run hash-matching against known-illegal-content lists and follow an escalation procedure on match — see Trust & privacy.

Who uses it

UGC and video platforms screening uploads before publication.
Dating and community apps moderating profile media and chat attachments.
Marketplaces and storage pipelines scanning CDN-hosted libraries in bulk, straight from the URL.
Media archives auditing large back-catalogs without re-downloading everything.

Why video?

They won't take your files. Sightengine caps video at 50–500MB, and Rekognition's published on-demand pricing works out to ~€12 for a 2-hour movie (competitor figures as of mid-2026) — we charge €0.40 (20-minute billing cap, every video).
Built for the hard cases. Multi-GB files, fragmented MP4s, corrupt indexes — analyzed end to end, not three lucky frames.
Your content is never retained. Frames are deleted within minutes of the verdict. We keep hashes and verdicts, never your media.
Private deployment. A dedicated single-tenant environment for teams whose data can't share infrastructure — your region, zero retention, private networking. Operated by us; you never manage a model.
