Changelog — Scratch

0.1.0 — initial release

Unreleased — private alpha

The first release of Scratch. macOS, Apple silicon.

Three-step setup on first launch: appearance, summon shortcut, dock visibility. Skip at any step and the walkthrough buffers still seed.
Five pre-loaded walkthrough buffers appear after setup: welcome, keyboard shortcuts, Markdown and slash commands, capture text (with a plain-language buffer about the screen-recording permission), and a pointer to settings. They behave like any other buffer.

Single global hotkey (⌥Space by default) summons and dismisses the window from anywhere on macOS.
Always-on Markdown editor (CodeMirror 6) with live preview, slash commands, and GFM.
Cross-buffer search (⌘⇧F) over every buffer, plus in-buffer find (⌘F).
Local-only by design: buffers live as plain Markdown files in your application data folder. No account, no sync service, no server-side copy.
Choose where buffers are stored (Settings → General → Buffer location) — point it at iCloud Drive or Dropbox to sync across machines, with an optional copy of your existing buffers. Changes made by a sync client or another machine reflect live; only genuinely different content on disk counts as a change, so a byte-for-byte sync echo never raises a false alarm. If the open buffer changes on disk while you have unsaved edits, a banner lets you keep yours or take the other version.

Configurable font size, line height, tab size, line numbers, spell check, and cursor style.
Three built-in themes (Bone, Slate, Slate Brass) plus custom themes saved from any appearance state.
Density preset (compact, cozy, comfortable) and accent color (four presets or any hex).

Lines that look like math get a live result at the end of the line — arithmetic, percentages, named variables scoped to a block, and x-as-multiplication between numbers.
Variables are italicized inline and autocomplete suggests them as you type (alongside sqrt, round, min, pi, and friends).
Unit conversion covers everything mathjs knows about (length, mass, time, area, volume, temperature, data). Use to or in between an expression and the target unit.
A faint dashed preview pill shows the result on the line you’re composing. Press Tab (or ⌘=) to bake the value into the buffer as plain text.
Local only. No network calls — currency conversion is intentionally out of scope.
The whole feature can be turned off in Settings → Editor → Inline calculations.

On-device rephrase via Apple Foundation Models. Off by default; enable in Settings → Intelligence. Requires macOS 26 on Apple silicon.
A floating pill appears above any text selection with four built-in tones (Tighten, Refine, Soften, Fix).
Up to six user-defined rephrase templates with a label and an instruction. Each one appears as a chip on the pill. The instruction is sent verbatim to the local model as a system prompt; nothing leaves the device.
One-off custom rewrites via the chat-bubble icon at the end of the pill — type a prompt, press Enter, and the rewrite lands in place. The instruction is discarded after use.

Pin (always-on-top), opacity, and remember-bounds toggles.
Auto-hide on blur, quit on close, launch at login, start hidden, dock visibility, and menu-bar visibility.
Customizable shortcuts for summon, settings, new buffer, next/previous buffer, and delete buffer. Conflict detection in the shortcuts panel.
Menu-bar tray with quick access to summon, settings, and quit.
macOS trackpad swipe gestures move between buffers.

Export the current buffer as Markdown, or all buffers as a .zip of Markdown files.
Send the current buffer to Obsidian or Apple Notes.
Capture text from any region of the screen — Scratch reads the selection and drops the recognized text into the buffer.
Reveal buffers folder from the File menu or settings.

A headless scratch CLI reads and writes the same buffers as the app. Nine commands (new, list, read, write, append, title, search, path, help), atomic writes, frontmatter preserved.
Honors the same buffer-location setting as the app, with SCRATCH_BUFFERS_DIR as an override. Works whether the app is running or not.

14-day local trial with clock-rollback protection. After expiry, existing buffers remain readable; new edits require activation.
Activation via Ed25519-signed license key, pasted into Settings → Activation.
Auto-update via GitHub Releases, with manual check from Help → Check for updates.

Settings → About lists every third-party open-source project bundled with Scratch, with its version, SPDX license, and full license text. Generated at build time from the production dependency tree.

Crash reports and usage metrics are off by default. Both are independent toggles in Settings → Privacy.
Buffer content is never transmitted. Crash payloads are limited to error name, truncated message, stack trace, Scratch version, OS version, and architecture.
Anonymous installation identifier (random UUID, persisted locally) is the only identifier sent.
