Song Cage

Overview

Song Cage is a songwriting workspace for building chords, melodies and lyrics together. It is best suited to writers who want music-theory-aware chord suggestions and a path from drafting to a DAW. Its main trade-off is a sharp gap between the capable free web editor and the more complete, one-time paid licence.

Key features

Harmony and melody

The chord palette spans diatonic and borrowed chords, secondary dominants, extensions and modulation routes. Suggestions are ranked against the melody and neighboring chords, which makes the tool more context-sensitive than a simple chord list. Melody tools are included too. This should appeal to songwriters shaping progressions around a tune, though it is not an AI co-writer: Song Cage says its suggestions follow music-theory rules.

Lyrics and recording

The lyric workspace offers perfect and slant rhymes, synonyms, semantic suggestions and a verb-and-noun generator. These dictionary-based tools help explore wording without claiming to write lyrics for you. Playback and audio recording are included on the free plan, making it possible to work with a song idea beyond text and chords.

DAW workflow

The AU/VST3 plugin supports Logic Pro, GarageBand, Ableton Live, FL Studio, Cubase, Reaper and Studio One. It streams chord and melody MIDI in sync with the DAW transport and saves songs inside the DAW project, a practical bridge for writers who arrange in those applications. Pro Tools AAX is not supported in this version, so Pro Tools users should look elsewhere for an integrated plugin workflow.

Pricing

The Free plan costs nothing, requires no card and is limited to one song. It includes the web app, chord palette, voicings and modulation, word tools, playback, audio recording, song-file export and view-only share links. That is a useful way to develop one active project, but the single-song cap makes it a poor fit for maintaining a growing catalogue.

The Song Cage licence costs $99, paid once, billed as a 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 the Ideas inbox, collaborators and web/desktop sync. For writers who need those workflow additions, the absence of a recurring subscription is appealing; casual users who only need the web editor may find the free plan sufficient.

A 14-day trial is offered. Song Cage also offers a full refund within 30 days by email. No separate recurring plan is described.

Platforms

Song Cage is available on Android, iOS, macOS, web and Windows, but the mobile app is a companion rather than the full editor. The free iPhone and Android app captures voice memos, lyrics and chord ideas offline without an account; it does not include the full editor, timeline, export or DAW support.

The native desktop app works offline and requires macOS 12 or later on Apple Silicon or Intel, or Windows 10 or later on 64-bit x64. That offline capability suits writers who want to work without a connection. Song Cage says song content is excluded from diagnostic telemetry and is not used to train AI models; it also says it does not sell personal data. Dormant accounts without an active subscription or trial may have cloud recordings and Ideas inbox captures removed after 12 months of inactivity, with at least 30 days' warning. Songs are not covered by that removal.

Who it's for

Song Cage is a strong fit for songwriters who want harmony, melody and lyric tools in one workspace, especially those who use a supported DAW or want offline desktop editing. It is less suitable for people who need a full mobile editor, depend on Pro Tools AAX, or want more than one song without paying.

Pros and cons

• Pros: Chord suggestions account for melody and neighboring chords, rather than presenting options without musical context.
• Pros: The one-time licence adds unlimited songs, desktop software, MIDI export and a DAW plugin without a recurring charge.
• Pros: Mobile idea capture works offline and without an account.
• Cons: The free plan is capped at one song, limiting its usefulness as a long-term library.
• Cons: Mobile lacks the full editor, timeline, export and DAW support.
• Cons: The plugin does not support Pro Tools AAX.

Alternatives

Songwriting Software is the broader category directory for comparing tools across the field.

• Suno is an alternative for writers who prefer an Android or iOS app with a free plan that includes 50 credits per day and an 8-minute audio upload allowance.
• Zoundroom is worth considering for mobile and web collaboration: its free plan supports up to two active projects, limited files, basic recording and notes, and sharing with up to two artists.
• Hookpad is a web-only option for chord and melody work with Smart Guides and unlimited cloud saves on its free plan; advanced features have one-minute previews.
• Songkeeper Studio suits mobile writers who want a free allowance of five songs, two drafts and two recordings per song, with writing tools and clipboard paste.
• Songzap is an iOS and macOS alternative focused on a four-track linear recording and arrangement workflow.
• Mureka is a web, Windows and macOS alternative.
• Songcraft is a web-based alternative.
• SongScribe is an iOS, macOS and web alternative.

Verdict

Choose Song Cage if you want a songwriting canvas that connects theory-aware chord work, lyrics and melody to offline desktop editing and a supported DAW. The free plan is a sensible one-song trial, but the one-time licence is the real proposition for writers who need a larger library, MIDI export or collaboration. Look elsewhere if you need a complete mobile editor or Pro Tools integration.
