Summary

A developer introduces Primnox, a desktop AI tool that runs a local NER model to scrub personally identifiable information before sending data to the cloud, featuring a self-building knowledge graph, deep research mode, and markdown notes with AI actions.

Been building this for a few months. It's called Primnox. The core thing: before ANY message leaves your machine, a local DeBERTa NER model runs on-device, finds names/emails/addresses/phone numbers, swaps them for stable placeholders (FIRSTNAME, EMAIL etc), sends the tokens to the cloud, and rehydrates the real data in the reply. The cloud never sees your actual PII. I typed "draft an email to Dr. Sarah Chen at [[email protected]](mailto:[email protected]), meeting at 42 Maple Street, call me on 555-0142" and the badge showed PRIVACY MIRROR - 10 SCRUBBED. The cloud got tokens, I got a real email back. Other stuff it does: - Knowledge graph that builds itself from your notes and convos (43 nodes, 184 connections, didn't configure anything) - Deep research mode hits 34 sources, reads full pages, produces a cited report with numbered references (~35 seconds standard mode) - Markdown notes with AI actions built in - Calendar, reminders, tasks, meeting recordings - Dynamic Island overlay so it's always ambient without being in the way BSL 1.1, flips to AGPL in 2029: https://github.com/primnox/main (its private for a moment I will make it public in 2 hours) Website: https://primnox.github.io https://preview.redd.it/c5bu5ykwukah1.jpg?width=1614&format=pjpg&auto=webp&s=8a33fa3663e797f779043d9391fb4ad81e8051f3 https://preview.redd.it/aesfdzkwukah1.jpg?width=1614&format=pjpg&auto=webp&s=ad9ecec767541f9c8c2a8fddb34e9f4c1bb98c08 https://preview.redd.it/jfto6zkwukah1.jpg?width=1614&format=pjpg&auto=webp&s=35ead167677c8431100660c20de1e23b62667dee https://preview.redd.it/g1clgzkwukah1.jpg?width=1614&format=pjpg&auto=webp&s=6258c3cc449502146969a19401d205db9e2f99ce https://preview.redd.it/u7qfpzkwukah1.jpg?width=1614&format=pjpg&auto=webp&s=82a02296519e7547d7f6747c067f53c117dc5660 https://preview.redd.it/l3zik0lwukah1.jpg?width=1614&format=pjpg&auto=webp&s=9dd425d3c5acc99f20ff78447a73031ac57dd095 https://preview.redd.it/ckkpe0lwukah1.jpg?width=1614&format=pjpg&auto=webp&s=ca8e4fc6b29d346a3fb0d48de5ab50efd8c55574 Edit:- I need more people to make this bigger T_T
