t-notes

Local-first, single-user notes + kanban board. Trello's core, none of its cloud — zero dependencies, tiny RAM.

Features

• Notes — + New note popup: title first, rich text (bold, italic, color, size), optional board List (a listed note also appears as a board card; same item, both views, edits sync). ✎ reopens the popup to edit; clicking the note opens a detail dialog (body + checklist + progress, list picker, image attachments). Archive, color labels, #tags
• Board — Jira-style color-coded lists (create with the New list… box, rename ✎ / delete ×). Cards with detail view: rich description, checklist + progress bar, due dates + overdue highlight, comments, label strips, #tags, drag & drop + ←/→ move. Notes pinned to a list render as cards too (draggable between columns). Both support image attachments (compressed locally, click to view full-size)
• Search + filter — text search, label and #tag filters
• Archive + activity log, checklist-item → card conversion
• Toasts confirm every action; ? button opens the in-app guide
• Light/dark/midnight themes (follows system, toggle cycles and persists)
• AI assistant (BYOK) — Command Code default (meta/muse-spark-1.3-contributor), plus OpenCode Zen free, OpenRouter, or any OpenAI-compatible URL. Summarize, Checklist, Improve, Ideas in notes and cards. Key stays local, never exported
• All data stays in your browser (localStorage t-notes-v1)

Run it (any OS with a browser)

cd t-notes/web
python3 -m http.server 8000
# open http://localhost:8000

No build step, no npm install. Just static files.

Windows installer (built from Linux)

sh build-windows.sh   # needs only Go → dist/t-notes.exe + dist/t-notes-setup.exe

• Copy dist/t-notes-setup.exe to Windows and run it: installs to %LocalAppData%\t-notes, creates Desktop + Start Menu shortcuts, launches.
• t-notes.exe also runs portable (no install).
• Uninstall: t-notes.exe --uninstall, then delete %LocalAppData%\t-notes.
• Auto-startup: ⏻ button in the header toggles launch-on-login (Windows Startup shortcut; highlighted blue when on).
• Backup: ⤓ exports all data as JSON, ⤒ restores it.

Layout

File	What
web/	Frontend: index.html, styles.css, app.js, logo.svg (no framework)
main.go	Windows host: local server + self-installer with shortcuts
build-windows.sh	GOOS=windows go build cross-compile from Linux
src-tauri/	Tauri desktop app (NSIS installer, autostart plugin)
e2e/	Playwright suite (system Chromium, mocked AI endpoint)
.github/workflows/	windows build CI → published GitHub Release

Real desktop app (Tauri)

The Go exe above is a browser launcher. For a usual Windows program — own window, t-notes-setup.exe installer with Start Menu + Desktop shortcuts, proper uninstall entry — Tauri builds it on GitHub Actions:

• Push a tag: git tag vX.Y.Z && git push origin vX.Y.Z, or run the windows build workflow manually. The installer publishes itself under GitHub Releases (no draft step).
• Local dev (Linux): npm install then npx tauri dev (needs Rust).
• The ⏻ startup toggle works in both builds (Tauri autostart plugin vs Go /api/startup fallback).

Release notes

• The installer is unsigned: Windows SmartScreen will show an "Unknown publisher" warning — click More info → Run anyway. Signing (paid cert) is the fix, skipped for now.
• No auto-updater yet: new versions are manual downloads from GitHub Releases.
• First install needs internet once (WebView2 bootstrapper); nearly all Windows 10/11 PCs already have WebView2 via Edge/Windows Update.

Tests

cd e2e && npm install && npx playwright test   # system Chromium, no browser downloads

10 tests cover: popup composer, rich text, labels, notes add/tag/persist, card lifecycle (move, modal, checklist, due, labels, comments), import/export roundtrip, AI actions (mocked endpoint), guide, search, custom lists, theme persistence.

Lean by design

~38KB of frontend, ~10MB self-contained Go exe, ~30MB Tauri app. Renders 10k notes in ~25ms with a single-digit-MB JS heap (lists window at 50 + content-visibility); search is debounced with an opt-in Rust batch-match in Tauri for 2k+ corpora, and animations are transform/opacity only, respecting prefers-reduced-motion.
