Obsidian's privacy, without the setup
Obsidian keeps Markdown files on your device and leaves sync and AI to add-ons. VoiceKnight is a synced, end-to-end encrypted notebook with voice capture and an AI assistant built in.

The main difference
Obsidian is private by staying local: your vault is plain files that Obsidian never sees. Syncing them between devices takes its paid, end-to-end encrypted Sync service or a sync tool of your own. VoiceKnight syncs end-to-end encrypted notes across your devices on the free plan.
Obsidian has no built-in AI or transcription; community plugins add them, each with its own provider and data handling. VoiceKnight builds in voice to text and Oracle, with one set of permissions you control.
Which to choose
- 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.
