A side-by-side comparison of Thalia and Tonefold — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Thalia
Thalia
Native Mac app for agentic coding with Meta's Muse Code CLI: plan, steer, review diffs and open pull requests.
Key features
- Plan Mode: Muse works out the approach without editing your project, and you approve, request changes or discard the plan.
- Command Approval: Shows the full command before Allow is available, with keyboard shortcuts to approve, deny or stop a running turn.
- Snapshot Review: Lists tracked and untracked changes with text diffs and records the exact approved snapshot, invalidating approval if files change.
- Checkpoints and Rewind: Capture checkpoints and preview exactly which files a restore changes, with a safety checkpoint saved first.
- Push and Open PR: Writes the pull request title and description and pushes the branch via the GitHub CLI, with worktree support.
- MCP Connectors: Guided presets for GitHub, Linear, Cloudflare, Sentry and GitLab, with keys stored in the macOS Keychain.
- Voice Mode: Talk to Muse hands-free and hear replies read aloud in a Mac voice or ElevenLabs voice.
- Reusable Slash Commands: Save prompts as personal or per-project commands with $ARGUMENTS substitution.
Best for
- Feature Development: Open a repo, plan a feature with Muse, and review the diff before shipping.
- Safe Refactoring: Capture checkpoints before large edits and rewind with a preview if the result is wrong.
- Pull Request Workflow: Go from first request to an opened PR without leaving the app.
- Parallel Tasks: Use worktrees and separate chats to run independent tasks side by side.
- Issue-Driven Fixes: Connect Linear, Sentry or GitHub to pull in context for bug fixes.
- Hands-Free Coding: Dictate instructions and hear status replies while away from the keyboard.
Tonefold
vkfolio
Open-source desktop AI music composer that writes editable chords, melody, bass and drums into a piano roll from plain-language prompts.
Key features
- Layered Composer: Writes chords, melody, bass and drums on separate layers and sections, with eleven layer kinds.
- Editable Piano Roll: Every generated part is plain notes you can draw, move and resize, with velocity and drum lanes.

- Built-in Synth Playback: A General MIDI synth plays the song immediately, before choosing instruments.
- Flexible Export: Exports MIDI, a stereo WAV mix and one WAV stem per layer.
- Local or Cloud Models: Chat uses your Claude Code login or an Ollama model on your PC or LAN; the app itself works offline.
- DAW Plugin and CLI: Optional CLAP/VST3 plugin (FL Studio tested) and a CLI so Claude Code or Codex can compose.
Best for
- Song Sketching: Describe a mood and genre to get a full multi-layer draft in minutes.
- MIDI Production: Export generated parts as MIDI into a DAW for further arrangement.
- Stem Creation: Render one WAV per layer for mixing elsewhere.
- Learning Composition: Inspect and edit the notes of generated chords and melodies to learn structure.
- Agent-Driven Composing: Let Claude Code or Codex compose through the CLI and skill file.
- Kids and Simple Songs: Quickly generate simple key-specific songs and tweak them by hand.
