Harrington

Early Access — macOS

Write better songs.
Keep them yours.

Harrington is a songwriter's workbench for discovery, craft, and performance handoff — without handing authorship to AI.

Apple Silicon · macOS Tahoe 26

Your songs stay on your Mac. The AI stays in its lane.

You stay the author

Harrington never writes songs for you. It gives you angles to react to, then gets out of the way.

  • Song, section, and line tools return options
  • Your voice, intent, and decisions stay central
  • No auto-changes, ever

Built for real workflows

Write and refine in Harrington, then take your song wherever it needs to go.

  • Previewable PDF and Word export layouts
  • Native OnSong and ChordPro exports
  • Works with Planning Center and OnSong

Context-aware by design

The AI reads the song you are actually writing, not a generic prompt in isolation.

  • Song Vision, songwriter profile, and section context
  • Rhyme scheme and Song Coach summaries inform suggestions
  • External AI is optional BYOK, not the default

Constrained AI

Harrington's built-in AI runs on your Mac and suggests only inside the app.

  • It cannot act outside Harrington or control your files
  • Harrington does not train on your lyrics
  • BYOK sends deliberate requests, not control of the app or your files

Clarity

What Harrington is not

This distinction is the foundation for trust.

An AI song generator
A ghostwriter
An AI that controls your files
A DAW
A social platform
A team tool or shared license
An automation target or agent tool

It's a structured songwriting environment. A craft-aware assistant. A bridge from idea to usable artifact. It's a workbench — for one person, doing their own creative work.

Workflow

Discover → Shape → Polish → Export → Use

A clean path from first intent to usable artifact.

Vision → Section → Line → Song Review → Export
  1. Name the song's intent with Song Vision
  2. Capture your idea — lyrics, sections, chords, and flow
  3. Shape your sections and song flow arrangement
  4. Use line, section, and song-level AI only where each tool belongs
  5. Ask Song Coach or Theme Check when the whole song needs the outside view
  6. Export to OnSong, ChordPro, PDF, DOCX, or plain text

Bounded AI

Appropriate help at the right level.

The AI helps you discover insights and options, and each tool is scoped to the level of decision the songwriter is making.

Song level

Use these when the question is about the whole song: what it says, whether it coheres, and where it may be drifting.

  • Song Coach for persistent conversation
  • Theme Check for focus, support, and drift
  • Song Vision as the intent layer for every request

Section level

Use these when the question is about what a verse, chorus, bridge, or other section needs to do.

  • Structural Guidance for section shape
  • Chord Progression for Nashville-first harmonic options
  • Flow tools for arranging sections into a usable form

Line level

Use these when the work is local: a blank, a weak line, a sonic choice, or phrasing that needs craft attention.

  • Spark, Suggest, Refine, and Rhyme
  • Meter, syllable count, and rhyme scheme
  • Direction fields for line-specific intent

Spark belongs at the line level because it opens a local possibility. At the section or song level, the same move would drift toward generating the song for you. Harrington keeps the tool matched to the scale of the creative decision.
