+# DotCheck
+
+**See what's real.**
+
+DotCheck scores how AI-like **images**, **video frames**, and **text** look — so people can tell synthetic media from human-made content. Scoring runs on DotCheck infrastructure (not on-device). Closed weights: public Hub pages describe engines and measured gates; inference heads are not redistributed.
+
+**Leviathan** is DotCheck's product scoring system: in-house engines (Vermeer · Valla · Muybridge) + generator-surface prior + shared content-hash cache. Same path for Free, Premium, and Pro — not a tier upsell.
+
+## Engines (this org)
+
+| Label | Modality | Wire | Hub model (docs only) |
+|-------|----------|------|------------------------|
+| **Vermeer** | Image | `inhouse@5` | [`DotCheck/vermeer-image-v5`](https://huggingface.co/DotCheck/vermeer-image-v5) |
+| **Valla** | Text | `inhouse-text@9` (+ lang heads) | [`DotCheck/valla-text-v9`](https://huggingface.co/DotCheck/valla-text-v9) |
+| **Muybridge** | Video frames | `inhouse-video@2` | [`DotCheck/muybridge-video-v2`](https://huggingface.co/DotCheck/muybridge-video-v2) |

+Public claim floats are lockstep with product facts (`Data.json` / MODEL-CHOICE). Do not invent accuracy numbers from bake-off shortlists.

+## Weights policy
+
+DotCheck heads are **closed**. Hub model repos in this org publish **cards and license text only** — no `.npz` / checkpoint files on public repos. Use Check or the Pro API; do **not** call `from_pretrained` on DotCheck head repos expecting runnable weights.
