One focused app for writing, organizing, and finding your notes again.
Threat model notes
## Recovery phrase
Store your 24-word phrase offline — it's the only way back in.
✓Write it on paper, not a screenshot
Real encryption, not marketing
Your notes are encrypted before they ever touch the disk, with a threat model built for people who actually read the crypto section.
How your key is protected
Self-calibrating Argon2id
At vault creation, Notvex benchmarks your machine and picks the strongest Argon2id tier — up to 512MB and 4 passes — that still unlocks in about 1.5 seconds.
Optional key-file 2FA
Layer a second factor onto your password: any file up to 1MB, bound into the wrap key alongside your passphrase.
How your data is protected
Two independent encryption layers
The entire database is encrypted at rest with SQLCipher (AES-256). Inside that, each note's title and content are separately encrypted with XChaCha20-Poly1305 using per-field random nonces.
Hardened against memory attacks
The master key lives in locked, non-swappable memory and is zeroed on lock. Auto-lock kicks in after 15 minutes idle by default, screen-capture protection blocks recordings, and failed unlocks trigger escalating delays.
You stay in control
Fully local, zero network
No account, no server, no sync. Notvex never phones home — the only network call it ever makes is checking GitHub for app updates.
Your data, your keys
A 24-word BIP39 recovery phrase — the same standard crypto wallets use — is generated at vault creation and is the only way to recover a lost password. There is no server-side reset, so keep it safe.
Everything you need, nothing you don't
A focused note-taking experience built for people who live in their editor.
Pin and soft-delete
Pin what matters, and recover deleted notes from Trash before they're gone for good.
Autosave, always
Every keystroke is saved as you type — there's no save button, and nothing to lose.
Crash-safe by design
Atomic writes and file-locking protect your vault from corruption, even on a hard crash.
Tags, not folders
Organize with colored tags instead of rigid folders — filter and combine them freely to find notes again.
Command palette
Jump to any note or action instantly with Ctrl+K — built for people who don't want to touch the mouse.
Multi-vault support
Keep separate encrypted vaults for work, personal, or projects, and switch between up to 5 recent vaults instantly.
