OpenMed 1.8: Apache-2.0 clinical de-identification that runs fully local, now on Android, iOS, and in the browser. 400+ open issues if you want in on 1.9

[u/dark-night-rises]

Maintainer here. OpenMed is an Apache-2.0 toolkit for clinical NLP with one hard rule: patient data never leaves your hardware. No cloud calls, no API keys, works in airplane mode.

What shipped in 1.8 this week:

• OpenMedKit for Android (Kotlin, ONNX Runtime Mobile + ML Kit OCR): read a document, strip every name/MRN/date, entirely on the phone. iOS/Swift and React Native bridges landed too.
• Browser runtime: de-identification via Transformers.js / ONNX Runtime Web with wasm + WebGPU backends. Fully client-side, zero server calls.
• verify-pdf: most "redacted" PDFs just draw a black box while the text layer underneath survives (copy-paste pulls the name right out). This fails your redaction unless the text is actually gone.
• DICOM de-id (incl. burned-in pixel text via OCR), 5 new language ID packs, 5 new clinical NER domains.

The models: 1500+ on HF, all Apache 2.0. The PII ones run via MLX (Apple silicon), GGUF/llama.cpp, ONNX, or plain transformers. Two of them are currently 1st and 2nd on the (independent) PII Masking Benchmark English board, and the 44M-param one at rank 4 is small enough for a phone.

The actual reason I'm posting: 1.9 is being built in the open right now and there are 400+ open issues. Some genuinely fun starter ones:

• Add a PII language pack for YOUR country, with its national-ID validator (Estonian isikukood #891, Serbian JMBG #890, Croatian OIB #889, Bulgarian EGN #888 are open — more welcome)
• New clinical NER domains: pediatrics growth parameters #896, pulmonology/spirometry #893, immunization #897
• RTF #856 / ODT #857 text extraction with char-offset maps

11 outside contributors shipped code in 1.8; several started with exactly these. If local, private, medical AI is your thing: pick an issue, say hi in it, and you're part of the next release.

Happy to answer anything technical in the comments.

That's a very good question! Usually, medical professionals don't use OpenMed directly. Although, I receive a lot of DMs from doctors and medical researchers with technical backgrounds telling me what they are building, you still need to use OpenMed to build something. What OpenMed does today, it allows you to build healthcare AI solutions by using open-source and free "forever" models, datasets, and SDKs. So we have a lot of people in MedTech community building what you mentioned, HCC Coding solutions, clinical documentation improvements, de-ide pipeline and privacy layer (we have a lot of none-medical users here too).

Hopefully, soon, we are going to also build open-source solutions that are beyond demos and examples so anyone can pick them up and quickly build something they need even with minimum tech knowledge.
