Song Cage

Song Cage is a songwriting workspace for developing chords, melodies and lyrics together. It suits songwriters who want theory-aware writing tools and, with the paid licence, a desktop editor connected to a DAW. Its free web plan is a useful one-song starting point; mobile is for capturing ideas, not editing a complete song.

Overview

The central appeal is a single canvas for musical and lyrical work. Chord suggestions take the melody and neighboring chords into account, while the lyric tools help explore wording. That combination is more relevant to writers shaping a song than to people seeking an automated track generator: Song Cage says it does not use AI to write songs.

There is a meaningful gap between platforms. The desktop app works offline, and the phone app can capture voice memos, lyrics and chord ideas offline without an account. But mobile omits the full editor, timeline, export and DAW integration, so it is a companion for collecting ideas rather than a substitute for the main workspace.

Key features

Harmony, melody and lyrics

The chord palette spans diatonic and borrowed chords, secondary dominants, extensions and modulation routes. Ranking suggestions against melody and nearby chords can help writers consider options in context rather than choose from an isolated chord list. Melody tools are included, though the free plan's one-song cap makes it a limited long-term workspace for anyone writing several songs.

The lyric workspace offers perfect and slant rhymes, synonyms, semantic suggestions, and a verb-and-noun generator. These are practical prompts for finding language; the maker says chord suggestions use music-theory rules and word tools use dictionary lookups, not AI-written songs.

Recording and DAW workflow

The free plan includes playback and audio recording. The paid AU/VST3 plugin streams chord and melody MIDI in sync with the DAW transport and saves songs inside the DAW project. It supports Logic Pro, GarageBand, Ableton Live, FL Studio, Cubase, Reaper and Studio One, but not Pro Tools AAX in this version. That makes the licence a better fit for writers already working in one of those DAWs than for Pro Tools users seeking an integrated plugin workflow.

Pricing

Song Cage is freemium, with a free plan and a 14-day trial. The free web plan costs nothing, requires no card, and is limited to one song. It includes the chord palette, voicings and modulation, word tools, playback, audio recording, song-file export and view-only share links. That is enough to develop and share a single project, but not to maintain a larger song library.

The Song Cage licence costs $99, paid once, billed as a $99 one-time payment. It removes the song limit and adds PDF chord sheets, MIDI export, Mac and Windows desktop apps, the AU/VST3 plugin, phone captures in an Ideas inbox, collaborators and web/desktop sync. It is the more suitable plan for writers with multiple projects who want exports or a desktop-to-DAW workflow; the trade-off is paying upfront rather than staying with the constrained free web plan.

The maker offers a full refund within 30 days by email. For dormant accounts without an active subscription or trial, cloud audio recordings and captured Ideas inbox items may be removed after 12 months of inactivity, with at least 30 days' warning; songs are not covered by that removal.

Platforms

Song Cage is available on web, macOS, Windows, iOS and Android. The native desktop app requires macOS 12 or later on Apple Silicon or Intel, or Windows 10 or later on 64-bit x64, and works offline. The free phone app also works offline for capturing ideas, but does not provide the full editor or exports.

Song Cage says song content is excluded from diagnostic telemetry, is not used to train AI models, and personal data is not sold. Its listed services include Supabase, Stripe, PayPal, Google OAuth, PowerSync, Datamuse, Cloudflare, Sentry and optional PostHog usage statistics. Support is available through the contact form or at [email protected].

Who it's for

Song Cage is a strong match for songwriters who want chord choices informed by melody, a dedicated lyric workspace and, on the paid licence, MIDI exchange with a supported DAW. The free tier suits someone exploring the tools or keeping one song in the web app. Writers who mainly need mobile capture can use the free phone app, but should not expect it to finish the job in the full editor. Pro Tools users should look elsewhere for AAX integration.

Pros and cons

• Pros: Chord suggestions are ranked against melody and neighboring chords, giving harmony choices useful musical context.
• Pros: The one-time licence adds unlimited songs, exports, desktop apps and a DAW plugin without a recurring plan price.
• Pros: Offline desktop use and account-free offline phone capture support different stages of writing.
• Cons: The free web plan allows just one song, which limits it as an ongoing library.
• Cons: Mobile lacks the full editor, timeline, export and DAW, so phone users must move elsewhere to develop or deliver songs.
• Cons: The plugin does not support Pro Tools AAX.

Alternatives

Songwriting Software is the broader category to explore if Song Cage's particular mix of theory, lyric tools and DAW integration does not fit.

For a different emphasis, consider Suno, which has free and paid plans and Android and iOS apps; Zoundroom, whose free plan supports up to two active projects and sharing with up to two artists; or Hookpad, a web option with free chords and melody, while advanced features are limited to one-minute previews on its free plan.

Mureka has a Basic Music & Speech plan at $8 a month, billed annually at $96, with monthly song and speech quotas. Songcraft offers a Pro plan at $5 a month and a free Basic plan capped at five songs. For a mobile-first alternative, Songkeeper Studio has a free Basic plan with five songs and a Pro plan at $0.99 a month. SongScribe offers a free plan with ten songs and a one-time Lifetime upgrade at 19.95 USD. SongSmith.io has a free web plan for up to five songs with writing and collaboration tools.

Verdict

Choose Song Cage if you want theory-aware chord work, lyric aids and a desktop songwriting workflow that can send MIDI to a supported DAW. The free one-song web plan is a low-commitment way to try its core approach, while the $99 one-time licence is the clear choice for a larger library and exports. Look elsewhere if you need a full mobile editor or Pro Tools AAX support.
