Open-source AI notetaker for the enterprise

Hyprnote is the first open-source AI notetaker for the enterprise. It runs fully on-device or on-prem, ensuring that no data ever leaves your system. Hyprnote transcribes and summarizes conversations automatically, turning discussions into actionable knowledge without risking security or regulatory breaches. Unlike cloud-based tools like Granola or Otter, Hyprnote is built for industries where data control is non-negotiable - tech firms, finance, healthcare, government, and beyond.

TL;DR

Hyprnote is an open-source AI notetaker for enterprises. It transcribes and summarizes meetings while keeping 100% of data on-device or on-prem — so companies stay in control.

Why Existing AI Notetakers Fail

Every other tool ships your conversations off to 3rd party clouds. Enterprises banned them because they violated data sovereignty.

How Hyprnote Flips the Script

Hyprnote runs entirely on your laptop, server, or air-gapped network:

Private by default: not a single byte leaves your system, ever.
AI-powered notes: clear, actionable summaries.
Enterprise-ready: HIPAA, SOC2, ITAR, FedRAMP-friendly.
Open source: transparent and extensible.
Flexible deployment: run it where you want.

Why We Built This

We saw enterprise employees stuck taking manual notes because “AI notetakers” weren’t actually enterprise-ready. Hyprnote exists so teams can finally use AI without giving up control of their data.

What You Can Do

1/ Introduce us to VPs or Directors driving digital transformation in regulated industries.

2/ Start using it FREE FOREVER — and spread the word.

3/ Star us on GitHub!
