SemantiNote is a brand-new app, so it isn't code-signed by Apple/Microsoft yet. Your computer may show a one-time security warning — it's not a virus, just an unrecognized new publisher. Here's how to open it (you only do this once, then it opens normally forever):
If you see “Windows protected your PC”:
If you see “can’t be opened… unidentified developer”:
Still stuck? System Settings → Privacy & Security → scroll down → Open Anyway.
The notebook, dictation, and keyword search are free forever. The AI — chat with your notes, summaries, semantic search, meeting recording, and adding new secrets — is free for 14 days, then a one-time $9.99 product key keeps it forever. No monthly fees, ever — less than the cost of a burrito.
Pay once, yours for good. No subscription.
Buy a product key — $9.99Checkout opens once builds are live. After buying, you'll get a key to paste into the app.
💯 100% satisfaction or your money back. If SemantiNote isn't for you, we'll refund you in full — just ask.
