NewConnections view for docs

The whole project, in one place.

Tasks, docs, databases and money live with the project they belong to, next to a password vault encrypted on your device. One calm app instead of five.

Replaces the stack you've been juggling

  • Notion
  • Todoist
  • Apple Notes
  • Password manager
  • Budget spreadsheets
All of it in Clusker

Your data stays yours: notes are plain Markdown files, and the vault is encrypted on your device.

What's inside

Twelve modules that fit together

Every module hangs off the project, so the tasks, the brief and the meeting notes are never more than a click apart.

See how work flows

How work flows

From first thought to finished project

Five steps every project goes through, all in one app and on the same data.

Capture

Out of your head in a second

Press Q on any screen and start typing. “Tomorrow 11:00”, a project, a label or a priority turn into fields as you go, so the task lands where it belongs and you get back to what you were doing.

Plan

See every project at a glance

View projects as a list, a gallery or a board with stages as columns. Each project carries a short code and a stage, so a pitch never gets mixed up with a job in progress.

Write together

Share the page, keep the file

Open a page together and you see each other’s faces in the header and your teammate’s caret in their color. ⌘Z undoes only your own edits. Underneath, the page is still a plain Markdown file.

Decide

See trouble coming

Project insights puts it all on one panel: what’s overdue or due this week, how far along the work is, what got done in the last seven days and who’s carrying what.

Hand off

Let Claude work alongside you

The Claude connector talks to the same API as the interface. A key is issued the moment you connect, and Claude can see and change exactly what you can, nothing more.

Up close

Built for everyday work

Tasks, pages, records and money share the same projects, people and permissions, so nothing gets copied between apps.

Tasks

Today, Upcoming and an hourly calendar

Tasks from all your teams in one list — and a Done log that shows what the week actually produced.

  • Subtasks and linked tasks
  • Quick add from any screen with Q
  • Bold and links right in the task title
app.clusker.io

Documents

See how your pages connect

The Connections view draws your pages as a graph, linked by project and folder, labels, @-mentions and tasks. Pages nothing points to sit apart, so they're easy to spot.

  • The same labels as your tasks, one click to filter
  • Browse as rows, covers or a graph
  • Every page is a plain Markdown file

Databases

Your own reference tables

Suppliers, materials, anything the project keeps track of — with the fields you need and nothing you don't.

  • Table, board and gallery over the same records
  • Filters, plus CSV import and export
  • A page for every record, with a cover
app.clusker.io

Canvas

Think in cards beside the page

A canvas lives inside the same document as the text — same folder, same access. Nothing to export, nothing to keep in sync.

  • Task and page cards stay live, not copies
  • Drop photos straight onto the canvas
  • Grow the tree from the keyboard
app.clusker.io

Finance

The project's money, not a spreadsheet

Every payment carries its project, so you can filter by it, and every team adds up into one overview.

  • Payments and budgets in several currencies
  • Accounts, cash and transfers between them
  • Only people you allow can see the money
app.clusker.io

Password vault

Passwords even our server can't read

The vault is encrypted on your device before anything leaves it. Our server keeps bytes it has no key to.

  • Unlock with Touch ID or Face ID
  • No API hands out what's inside
  • Never shows up in search, Markdown files or guest links

Teams & roles

Bring everyone in

Invite people in one step and give each the role they need. On team plans, a new person never changes the bill.

  • Four roles, set per team
  • Guest links to a single page or canvas
  • Notifications when others act on your things

Our approach

Opinions we built in

Clusker doesn't try to be everything. We made a few decisions on day one, and every screen follows from them.

  1. The project comes first

    Tasks, documents, records and money attach to a project instead of scattering across apps. A label says where the work stands, not what it's about.

  2. Your notes are plain files

    Every page is a Markdown file, and that file is the original, not an export. Two versions of your notes are never silently merged.

  3. Passwords are encrypted on your device

    The server stores your passwords but can't open them, and the vault has no API at all. Search, agents and guest links never reach it.

  4. No back door for agents

    The app, Claude over MCP and your own scripts all go through the same API. An agent gets exactly the teams and the role of the person whose key it holds.

  5. Finished, not an MVP

    No sprints, no story points, no half-built screens. Every view knows what to show when it's empty, when you don't have access and when the connection drops.

  6. Pricing that doesn't punish inviting

    You pay for the team, not for each person in it, so nobody thinks twice before inviting a bookkeeper for two documents or a contractor for a month.

“One product instead of Notion, Todoist, Apple Notes and a password manager — with the project, not the folder, at the center.”
