MODELocal-first desktop application

Tarizz project dashboard with draggable project cards, calendar, and diary shortcuts — 01 Project dashboard — a spacious starting point for every workspace, plan, and private entry.

01 // The idea

Productivity without surrendering privacy.

Creative work is usually fragmented across a project manager, notes app, file browser, diagram tool, calendar, and journal. Tarizz brings those workflows into one considered desktop product without sending the underlying work to a hosted service.

The interaction model stays simple: authenticate, choose a project card, and move between projects, calendar, and diary inside one window. Back and forward navigation preserve context while focused pages avoid the clutter of a permanently compressed workspace.

02 // Document workspace

A project tree built for real material.

Rich writing, nested pages, files, visual thinking, and portable exports live in the same project.

Tarizz rich document editor with project explorer, embedded image, and code block — EDITOR / 02 One-click project navigation with rich text, code blocks, Markdown preview, embedded media, and page-level export.

Rich documents

Write and format like a modern editor, preserve formatted clipboard content, preview Markdown, and export a single page or an entire project.

Embedded media

Keep images, video, and documents in context. Open files in their default app, save a copy, remove them, or resize images directly by dragging.

Visual flowcharts

Create shapes and directional connectors that remain attached as the canvas changes, with selection, detachment, deletion, zoom, and PNG export.

Encrypted vault

Projects remain local and encrypted. A separately protected diary relocks whenever you leave its page.

03 // Daily planning

Projects meet the day.

Calendar and tasks are not detached utilities. They are first-class parts of the dashboard, letting work be assigned to projects, checked off with one click, and reviewed by date without opening another window.

Light and dark themes throughout

04 // Product decisions

A desktop tool that behaves like one system.

One-window navigation

Dashboard, projects, calendar, and diary are full-page states connected by history instead of a collection of modal windows.

Progressive workspace density

The dashboard stays spacious; the denser explorer-and-editor layout appears only when a project needs it.

Local data as a feature

Authentication, encrypted storage, media records, tasks, and diary entries remain controlled by the user’s own machine.

Portability at every level

Export individual documents or complete projects to practical formats, and save embedded media back out whenever needed.

05 // Get the app

Keep your workspace on your machine.
