Help

Bitfield is a personal daily canvas — notes, links, images, checklists, shapes, Pomodoro timers, and freehand drawings, organized by calendar day with page tabs.

It is a second brain for today, not a shared whiteboard. Each account has its own private days.

In this guide

• Using the canvas — tools, pan/zoom, search, export, iPad / PWA
• Self-host — Docker Compose, disk uploads, local bootstrap
• Cloud deploy — Vercel + Postgres + object storage
• Accounts & invites — sign-in, signup lock, inviting friends

Open Help from the canvas header (question-mark icon) to come back here. Signed-out visitors can open the same pages from the splash.

Engineering notes (product spec, ticket boards) stay in the git docs/ folder and are not part of this wiki.
