Pilcrow builds on third-party machine-learning models and the datasets used to train them. This file lists those components and their license terms. License information was verified on Hugging Face on 2026-06-21.
Apple system frameworks (Core ML, Vision, ScreenCaptureKit, AppKit,
NaturalLanguage, and related macOS components) are provided by the operating
system and require no attribution here. The pixel-art pet assets shipped with
the app are generated by the project's own tooling (scripts/generate-pets.py).

Shipped weights: an in-house ModernBERT-large sequence-classification fine-tune trained from the Apache-2.0 base above, over the project's own deconfounded matched-pair corpus, then exported to Core ML with
scripts/convert-stage2-modernbert.py. The training checkpoint'sconfig.jsonrecords_name_or_path: answerdotai/ModernBERT-large, so the weights derive solely from the Apache-2.0 base — no unlicensed weights are involved — and the Apache License 2.0 reproduced below applies to them in full.The earlier preview build fine-tuned the unlicensed
Donnyed/LLM_Detector_Preview_model; that lineage has been removed and replaced by this clean-base retrain.
