Your notes aren't their business
VoiceKnight is the only app here with end-to-end encrypted notes, voice to text and an AI assistant that reads only what you allow. It's simple from the first note: privacy is the default, and the powerful features stay out of the way until you want them.

Which to choose
Notion
- Pick Notion for team wikis, project databases, integrations and real-time collaboration across a company.
- Pick VoiceKnight for personal notes. Notion can read your workspace and its AI draws on all of it, voice capture is a paid add-on, and the free plan is limited once you collaborate.
Evernote
- Pick Evernote for web clipping, document scanning, search inside images and PDFs, and a long-established ecosystem.
- Pick VoiceKnight for notes only you can read. Evernote holds the keys, encrypts only text you select, and its free plan stops at 50 notes on one device.
Obsidian
- Pick Obsidian for Markdown files you own on your own disk, full offline use, backlinks and a huge plugin ecosystem.
- Pick VoiceKnight for less setup. Sync, voice to text and AI are built in, where Obsidian needs paid Sync or your own tool, and plugins that each handle your data their own way.
Standard Notes
- Pick Standard Notes for fully open-source apps and server, self-hosting, and a minimal, long-standing encrypted notebook.
- Pick VoiceKnight for more than text. VoiceKnight adds voice capture, an AI assistant you control and encrypted collaboration, where Standard Notes has none of these and its free plan is plain text only.
