May 2026A specimen of in-flight work, sealed

Your open loops,sealed.

A bench for everything you've started. Tasks in flight, notes still in the thinking, this morning's scratch — sealed in your browser before any of it leaves. We host the ciphertext. You hold the key.

Your vault,paired to your agent.

A local MCP server hands your sealed vault to Claude, Cursor, or anything that speaks the protocol. The process holds your identity keys in RAM and seals every byte before it hits the cloud.

What’s still open,on one page.

Start a task. Pick it back up. The bench remembers what you touched last — and quietly nudges you to wrap a few up when the loops pile up.

The method

I — Sealed at the source

Encrypted before it leaves the keyboard.

Every keystroke is wrapped on your device. The server stores opaque ciphertext keyed to a vault only you can open. There is no read-side for us to misuse.

II — Capture without ceremony

One line. The right place.

Quick-add parses dates, priorities, and projects from natural language. “Email Sam tomorrow 3pm p1 #inbox” lands where it belongs, with the date you meant.

III — Drive it with your own LLM

A filesystem for your sealed vault.

npx @paperjot/mcp pairs your laptop in two minutes. Claude Desktop, Claude Code, Cursor — point any of them at the bench and they read your loops as markdown files. Paperjot’s servers see nothing change.

The catalogue

Sixteen features, set in type. Every one runs on the same end-to-end encrypted vault.

Capture

Quick-add.: One line. Dates, priorities, projects parsed in-browser.
Inbox triage.: Keyboard-driven: space, 1–4, m, x.
Journal.: One entry per day. Stitches what you touched.
Workbench.: Open loops, today, scratch — one tray.

Organize

Projects & sections.: Tabs hold notes and tasks side by side.
Labels.: Project-scoped. Filterable in the same query.
Priorities.: P1 to P4, in Todoist’s colours.
Today & Upcoming.: Aggregated across projects. Drag to reschedule.
Subtasks.: Nested, with honest progress.
Recurrence.: RRULE under the hood. “Every other Tuesday” works.

Write & attach

Encrypted notes.: Yjs CRDT. Sealed before it leaves the keyboard.
Backlinks.: Pull a note snippet straight into a task.
Files.: Per-file keys. Chunk-streamed. Decrypts to disk where it can.

Project sharing.: Per-member key wrap. Revoke means revoke.
Comments & @mentions.: Append-only. Encrypted. Parsed for names.
Notifications.: Shares, mentions, assignments — one feed per vault.

More specimens

Notes, queries, and threads — set in the same press, sealed under the same lock.

We can't read your work. Neither can our hosting provider, our employees, or anyone with a subpoena. The math, not the policy, is what makes that true.
