Prosaic

A writer-first terminal writing app built with Python and Textual, built with the assistance of LLM/Copilot tools.

Motivation

I write on multiple devices (an iPad, a laptop, even more), and I wanted a quick way to start every day, get some frontmatter ready for my daily pieces on journal.coffee, jot down notes and even work on books. I have tried several software, some stellar, some half-assed, some bloated, some minimal, but I felt like I needed something of my own.

So, I decided that the best way to go about it is to have a TUI. I can access it from anywhere, and mostly, it will do the job. This way, I can access it from a terminal app on the iPad or Windows (cue: Termix on a browser) and on the Macbook. Hence, Prosaic was born.

Full disclosure: I did rely on LLMs to make it, but as much as I could, I tried to get it to follow best practices, good architecture, and clean code principles.

Profiles

Profiles let you maintain separate workspaces for different writing projects (personal, work, fiction, etc.).

# List profiles
prosaic --profiles

# Use a specific profile
prosaic --profile work

# Create a new profile (runs setup wizard)
prosaic --profile fiction

Each profile has its own:

• Archive directory
• Git remote (optional)
• Theme preference
• Spell check language (80+ languages supported)

Manage profiles from the dashboard menu (m key) or edit in ~/.config/prosaic/settings.json.

Upgrading from v1.1.1 or older? Your existing setup is automatically preserved as the "default" profile. On first launch after upgrading, you'll be offered the option to set up additional profiles or rename your default.

Spell Check

Prosaic supports 80+ languages powered by hunspell, including English, Spanish, French, German, Arabic, Hungarian, Polish, and many more.

# List all supported languages
prosaic --languages

Spell check settings:

• Language is set per profile during setup
• Toggle on/off with F7 in the editor
• Change language anytime in manage profiles (m key on dashboard)
• Status bar shows spellcheck:on or spellcheck:off
• Existing users are prompted to set a language on first launch after upgrading

Common language codes: en_US, en_GB, es_ES, fr_FR, de_DE, pt_BR, ar, hu_HU, pl_PL, ja, zh_CN, ru_RU

Books

Books are long-form writing projects stored as directories in your archive's books/ folder.

my-book/
  chapters/               Individual chapter files
    chapter-one.md
    chapter-two.md
  chapters.md             Chapter reading order (one filename per line)
  manuscript.md           Auto-generated compilation (read-only)

Working on a book:

1. Press b on the dashboard to open book selection
2. Select an existing book or create a new one
3. Select an existing chapter or create a new one
4. The manuscript auto-compiles on every save and when you leave a chapter
5. Press m in chapter selection to compile manually at any time

The manuscript is read-only in Prosaic — edit your chapters, not the manuscript directly.

Upgrading from v1.3.4 or older? Legacy books (single .md files) are automatically migrated to this structure on first open. Your original file is preserved with a .bak extension.

Configuration

Config location (in order of priority):

1. PROSAIC_CONFIG_DIR env var (explicit override)
2. $XDG_CONFIG_HOME/prosaic/ (Linux standard)
3. ~/.config/prosaic/ (default)

Override with environment variable:

PROSAIC_CONFIG_DIR=~/custom/path prosaic

Git Integration

If your chosen archive directory already contains a git repository, the wizard will:

• Detect the existing .git directory
• Inherit the repository (no re-initialization)
• Read the remote URL if configured
• Prompt for a remote URL if none exists
• Store this info in settings.json

Example settings.json:

{
  "app_version": "1.5.1",
  "setup_complete": true,
  "active_profile": "default",
  "profiles": {
    "default": {
      "archive_dir": "/Users/you/Prosaic",
      "init_git": true,
      "git_remote": "git@github.com:you/writing.git",
      "theme": "light",
      "spell_lang": "en_US",
      "spell_check": true,
      "last_file": "/Users/you/Prosaic/pieces/2026-03-03-example.md"
    }
  }
}
