The product model

A knowledge workspace, not another dashboard.

The library stays simple. Categories organize workspaces. Each workspace owns its notes and canvas. No separate graph, database, or file-explorer hierarchy to manage.

Group knowledge without turning Home into a tree view.

Browse progressively, then open a category when you need search, filtering, sorting, and the full workspace list.

WORKSPACE

Keep writing and spatial thinking in one durable context.

A workspace can hold multiple notes plus one canvas, with split layouts when you need to see them together.

NOTE / CANVAS

Use the right surface without creating another top-level object.

Write structured notes with Tiptap. Sketch systems and relationships with Excalidraw. Both remain owned by the workspace.

Core workflow

Capture → work → find → resume.

The landing page mirrors the real product loop instead of selling a pile of disconnected features.

01 / CAPTURE

Save an idea where it belongs.

Quick Capture creates a durable note inside an existing workspace, including Markdown import.

02 / WORK

Write and sketch side by side.

Use Note, Canvas, or bounded split panes without leaving the workspace context.

03 / FIND

Return to the exact context.

Global search resolves categories, workspaces, notes, and exact blocks instead of only matching titles.

04 / RECOVER

Own a path back.

Workspace history and full-library backup keep recovery explicit without duplicating your source of truth.

Self-hosting

Run the whole workspace yourself.

Notespace ships as one Go application serving the web UI and API, with SQLite for durable state. Docker Compose is the default deployment path.
