Claspt app — travel notes with locked passwords, packing checklist, and budget table

New here? Not sure what a "vault" or "encryption" means?

We have a simple, jargon-free page that explains what Claspt does in plain English. No technical knowledge needed.

The Problem

You're juggling too many tools.

Passwords in one app. Notes in another. Important stuff scattered across Slack messages, emails, and random files. Sound familiar?

Passwords in one app, notes in another

Your notes are in one app, your passwords in another. When you need both together -like login details next to setup instructions -you end up copy-pasting between tools.

Rigid forms that don't fit your life

Password managers give you rigid forms -username, password, URL. But what about WiFi passwords with notes about the router? Software license keys? Recovery codes with instructions on when to use them?

Proprietary lock-in

Your data is trapped in someone else's format, on someone else's server, behind someone else's subscription. Export is an afterthought, if it exists at all.


The Claspt Difference

Notes and passwords, side by side.

Write Notes Like You Normally Would

A clean, distraction-free editor for any kind of note -meeting notes, project plans, journal entries, recipes, or technical documentation. Formatting is simple and visual, with support for headings, bold, links, tables, checklists, and more.

  • Rich text formatting -headings, bold, links, images
  • Tables, checklists, and callout boxes
  • Code blocks with syntax highlighting

Lock Any Part of Your Notes

Add a password, credit card number, or any sensitive info right inside your notes. The locked parts are encrypted and hidden -only you can reveal them with your fingerprint or master password. Your notes stay readable. Your secrets stay private.

  • Bank-grade encryption on every locked item
  • Unlock with fingerprint, Face ID, or your master password
  • Flexible fields -not rigid username/password forms

Search Everything in < 100ms

Press Cmd+K and find any note, password, or tag instantly. Search across everything you've saved, even with thousands of entries.

  • Full-text search across notes and secrets
  • Filter by tags, type, or date
  • Fuzzy matching (handles typos)

How It Works

Set up in 2 minutes. Seriously.

1

Create Your Vault

Pick a folder on your computer. Set a master password. That's it -you have a private, encrypted space for all your notes and passwords. No account creation, no email required.

2

Write Notes, Add Secrets

Write notes like you normally would. When you need to store something sensitive -a password, a credit card, a license key -lock it right inside the note. Only you can see it.

3

Search, Sync, Sleep Well

Find any note or password instantly with search. Every change is saved automatically with full history. Upgrade to Pro to sync across your devices.

Features

Everything you need. Nothing you don't.

Lock Sensitive Info Inside Notes

Passwords, credit cards, and private info are encrypted right inside your notes. Reveal with your fingerprint or master password. Auto-locks when you step away.

Beautiful Notes Editor

Write with headings, bold, links, tables, checklists, and more. Visual or text mode. Keyboard shortcuts for everything. Feels like a real writing app.

Find Anything Instantly

Search all your notes and passwords in milliseconds. Type a few letters and results appear immediately. Never lose track of anything again.

Never Lose a Change

Every save is automatically tracked. See what changed, when, and roll back to any previous version with one click. Your notes have a complete history.

Biometric Unlock

Unlock your vault with Touch ID, Face ID, or Windows Hello. Fast access without typing your master password every time. Hardware-backed security.

Sync Across Devices

Access your passwords and notes on all your computers. Everything is encrypted before it leaves your device. Available on Pro and Pro+ plans.

Share Passwords Safely

Send a password or note to someone with a self-destructing link. Set it to expire after one view or a time limit. They don't need a Claspt account.

20 Themes

Nord, Dracula, Catppuccin, Tokyo Night, GitHub Dark, Everforest, Kanagawa, and 13 more. Your vault, your aesthetic. Switch themes instantly from the command palette.

Works with AI Tools

Connect Claspt to AI assistants like Claude, Cursor, and Windsurf. They can search your notes while your passwords stay locked. Great for developers.

15 Built-in Extras

Diagrams, charts, kanban boards, spreadsheets, math formulas, and more -all built into the editor. No plugins to install.

Password Generator

Generate strong passwords, memorable passphrases, or PINs. Built-in strength checker tells you if your password is weak. Create and save in one step.


AI Memory

For developers: connect your AI tools.

If you use AI coding assistants like Claude, Cursor, or Windsurf, Claspt can give them access to your notes while keeping your passwords locked. This section is for developers -skip it if that's not you.

Connect

Add Claspt's MCP server to Claude Code, Cursor, or Windsurf. One config line. No plugins, no extensions.

Store

AI agents save project context, decisions, and conversation summaries as encrypted vault pages and memory entries.

Recall

Next session, your AI reads back its context from the vault. No re-explaining. No lost decisions. Persistent memory across conversations.

Two-Tier Tokens

Give agents a clsn_ notes token for full read/write access to pages, while your secrets stay locked behind a separate clss_ token. Automatic redaction of secret blocks on notes-scoped requests.

Agent Memory Store

Persistent key-value storage at /api/memory/:namespace. AI agents store and retrieve context across sessions -with automatic TTL cleanup and encrypted vault-level protection.

Secret Access Approval

Optional approval popup when an agent requests secret-scoped access. 30-second timeout, “remember for session” option. You stay in control.

Works Everywhere

MCP server, HTTP API, CLI, and inbox folder. Claude Code, Cursor, Windsurf, Gemini CLI, custom scripts -anything that speaks JSON-RPC or HTTP.


Security

Your data stays private. Period.

Everything sensitive is encrypted on your computer before it goes anywhere. We can't read your data -and neither can anyone else. Built with the same encryption standards used by banks and governments.

Bank-Grade Encryption

Your passwords and secrets are scrambled using the same encryption standard (AES-256) that banks and governments use. Nobody can read them without your master password.

One Password to Remember

Your master password unlocks everything. It's processed through advanced security algorithms that make it extremely difficult for anyone to guess -even with powerful computers.

Built for Safety

The security engine is built with Rust -a programming language specifically designed to prevent the kind of bugs that cause data breaches in other software.

Safe Even When Syncing

When you sync across devices, your passwords are encrypted before they leave your computer. Even if the cloud storage is hacked, your secrets are unreadable.

What's encrypted vs. what's not

Encrypted

  • Passwords, credit cards, and private data
  • Labels on your locked items
  • File attachments

Plaintext (By Design)

  • Note titles and body text (so you can search them)
  • Folder names and tags
  • Change history timestamps

Why plaintext for non-secrets? Because full-text search, Git diffs, and grep all require readable text. Encrypting everything would break the features that make Claspt useful. Your passwords and sensitive info are the only things that get encrypted, and they get bank-grade protection.

Frequently Asked Questions

What happens when my Pro trial ends?

You keep full access to all your notes and secrets on desktop. Sync and mobile access stop working until you subscribe. No data is ever deleted.

What's the difference between Pro and Pro+?

Pro ($4/mo) syncs through your Google Drive — you bring the storage. Pro+ ($8/mo) adds 1 GB hosted encrypted storage with real-time WebSocket push sync, 10 devices, and priority support.

Is the free plan really free forever?

Yes. The desktop app with unlimited notes, secrets, encryption, search, and Git versioning is free forever. We make money from Pro subscriptions, not from locking basic features behind a paywall.

Can I share secrets with someone?

Yes, with Pro or Pro+. Create password-protected shared links with expiry and burn-after-reading. The secret self-destructs after it's viewed once.

How do you pronounce "Claspt"?

It rhymes with "grasped" — one syllable, /klæspt/. It's the archaic past tense of "clasp," as in "she claspt the locket shut." Your notes and secrets, claspt together.
