What the flux detector actually catches.
Six headline generators, sampled across every modality we cover. Each entry is benchmarked monthly against the vendor's latest release - we cycle the roster instead of padding it.

Accuracy & methodology
Benchmark first. Hype never.
We benchmark at 98.4% accuracy on a held-out 2026 set including Midjourney v8 Alpha, Flux 2 Pro and Ideogram v3, with a 1.8% false-positive rate. The detection pipeline runs frequency-domain analysis, EXIF inspection where present and a learned classifier trained on the latest model outputs. We publish confidence bands on every result.

FAQ
Common questions about the flux detector.
The flux detector is tuned against Flux 2 Pro and Flux 2 Schnell. New models are added to the ensemble within 30 days of release.
We benchmark at 99.1% accuracy on the RAID benchmark with a 1.2% false-positive rate for text, and 96.9-98.4% across image, audio and video. Every verdict ships with a confidence band so you know how certain the result is.
Edited prose, technical writing and ESL writing are common false-positive triggers for naive detectors. We tune against those failure modes specifically and surface confidence so a low-certainty AI verdict reads differently from a high-certainty one.
Yes. Every plan keeps every scan forever - Free included. There is no retention tier and never will be. You can delete an individual scan from /dashboard/history at any time.
No. Uploads are processed in-memory and never used to train detectors. We are SOC 2 in progress and ship a Data Processing Addendum.
Every signup gets $1 in scan credit, usable across every detector model - text, image, audio, video. There is no expiry while your account is active.
Yes - Starter handles 10 files at once, Pro 50 and Business 500. Drop a folder into the dashboard and we'll scan everything in parallel.
Yes - included on the Business plan. The API mirrors the dashboard, supports streaming results for long videos and ships an OpenAPI spec.
We don't sell humanisers, evasion or AI-paraphrasing. We're a verdict tool. If you want to bypass detection, this isn't the product for you.
