KeepZen - note-taking app for people who spend more time writing than organizing. No blocks, no databases, no noise. Just you and your thoughts.

Come back to clean writing. KeepZen removes the noise and leaves just you and your thoughts โ€” no complex setup, no tracking, just your words in calm, clear order.

Your notes are encrypted in your browser with your passphrase. The key never leaves your device โ€” we never see it, and we never store it. When you use sync, only encrypted data is sent to our servers. We cannot read your notes.

Zero-knowledge by design.

Start keeping your thoughts safe. No account required to get started. Your data stays with you. Optional sync when you're ready.

Questions & Answers

As answered by people managing Startup Notes and KeepZen.

Why should a person choose your product over its competitors?

KeepZen's answer:

KeepZen is built for those who refuse to choose between convenience and privacy. While mainstream tools scan your notes for AI training and "privacy-first" alternatives often require complex manual setup to sync, KeepZen offers a "Third Way." You get absolute end-to-end encryption (E2EE) and seamless multi-device sync out of the box. Itโ€™s the only tool that feels as simple as a notepad but is as secure as a digital vault.

What makes your product unique?

KeepZen's answer:

KeepZen occupies the "Goldilocks zone" of note-taking. It is zero-config private: you get the absolute security of end-to-end encryption (E2EE) and the speed of local-first architecture without having to set up a server or manage complex plugins. Itโ€™s a professional-grade vault that feels as simple as a piece of paper.

How would you describe the primary audience of your product?

KeepZen's answer:

Our users are "Digital Minimalists"โ€”writers, researchers, and creators who find themselves overwhelmed by the "noise" of modern productivity tools. They are individuals who value their intellectual privacy and want a sanctuary where they can think without being tracked, scanned, or interrupted by AI assistants.

What's the story behind your product?

KeepZen's answer:

KeepZen was born from a moment of frustration. I opened a popular note-taking app to capture a fleeting, personal thought, only to be met by a loading spinner and a popup for a new AI feature. The realization was immediate: our digital "private" spaces had become crowded and loud. KeepZen was built to reclaim that silenceโ€”creating a tool that stays out of your way and keeps your data truly yours.

Which are the primary technologies used for building your product?

KeepZen's answer:

  • Next.js: For a seamless, high-performance web experience.
  • IndexedDB: Powering the local-first storage so your notes are always accessible offline.
  • E2EE (Web Crypto API): Ensuring your notes are encrypted on your device before they ever hit the cloud.
  • PWA (Progressive Web App): Allowing the app to be installed on any device with native-like performance.
