| # Feemag Tools models |
|
|
| Unmodified open models used by the free in-browser tools at |
| [tools.feemag.com](https://tools.feemag.com). Every tool runs on the visitor's device; |
| these files are the only thing it downloads, and no user file is ever uploaded. |
|
|
| This repo only mirrors the files. Each model keeps its original licence, listed below |
| and in the licence file next to it. |
|
|

| ## File layout |
|
|
| Large files are split into 50 MiB parts named `<name>-<index>-<hash>.bin`. The JSON file |
| next to them (`u2net.json`, `<name>.onnx.json`) lists the parts in order with their SHA-256 |
| and the SHA-256 of the whole file; joining the parts in order gives back the original file |
| byte for byte. `ocr/sha256.json` lists the hashes of the two PaddleOCR archives. |
|
|
| The tools load these files from one fixed commit of this repo and check every hash in the |
| browser before using a file. |
