A desktop workspace for running Codex, Claude Code, Grok, OpenCode, Kimi Code and Antigravity in parallel Git worktrees.

Parallel Tasks in Git Worktrees: Every task runs in its own worktree so multiple agents work simultaneously without colliding, with dependencies set when one change needs another.
Six Supported Agents: Assign Codex, Claude Code, Grok, OpenCode, Kimi Code or Antigravity per task, using each agent's own installed CLI and permission rules.
Interactive Codebase Map: Browse resolved file dependencies to trace the reach of a change and choose what to inspect next during review.
Carried-Forward Project Context: Save project guidance once; new tasks match relevant guidelines to the prompt, inherit defaults, and let you inspect what the agent actually received.
Unified Code Review: Read each result beside its original brief, combine related patches into one review, request another pass, and decide what enters the project.
Named Account Profiles: Keep work and personal agent accounts separate with per-project defaults and per-account usage tracking.
Agent Browser and Computer Use: A separate browser session per task lets agents navigate pages, fill forms, capture screenshots and run accessibility checks; Windows desktop control adds approved window clicks, typing and scrolling.
Cross-Agent Messaging: Tasks share a project inventory with ownership, scopes and dependencies, and agents can send direct task messages or project broadcasts through a durable inbox.

Running Experiments Side by Side: Try two different approaches to the same problem with different agents and compare the resulting patches before choosing one.
Reviewing Agent Output Safely: Keep every generated change behind a human review step, with checks attached to the code they tested.
Comparing Coding Agents: Assign the same brief to Codex, Claude Code and Grok to see which handles your codebase best.
Separating Work and Personal Accounts: Use the right provider account per project without re-authenticating or risking cross-billing.
Understanding a Change's Blast Radius: Use the codebase map to see which files a proposed change touches before merging it.
Automating Verification: Let agents drive a sandboxed browser to fill forms, screenshot results and run accessibility audits as part of a task.

In-browser, on-device piano transcription: drag & drop audio to get a piano-roll view and slowed playback with no uploads.

On-Device Transcription: Runs the transcription model fully in the browser so audio is processed locally, minimizing latency and ensuring recordings are not uploaded to remote servers.
Drag-and-Drop Audio Input: Accepts common file formats (MP3, WAV, FLAC, M4A) via simple drag-and-drop to quickly start analysis without complex imports.
Piano-Roll Visualization: Generates an interactive piano-roll view of detected notes, showing pitch and timing to help users inspect performance details visually.
Variable Playback Speed: Allows slowing down audio playback to inspect fast passages or subtle timing details while keeping the visual transcription synchronized.
Local Privacy by Design: Architecture avoids cloud uploads, making the tool suitable for users concerned about confidentiality of recordings and intellectual property.
Immediate, Low-Latency Analysis: Browser execution provides near-instant transcription and visualization for rapid iteration during practice or review.
On-device piano transcription performed in the browser (no uploads to a server)
Drag-and-drop support for MP3, WAV, FLAC, M4A audio files
Piano-roll visual representation of detected notes
Playback controls including slow-down for practice and analysis
Local processing to preserve user privacy and eliminate file transfers

Practice Analysis: Students and teachers can upload practice recordings to inspect missed notes, timing, and articulation using the piano-roll and slowed playback.
Performance Review: Pianists can quickly analyze live or recorded performances for phrasing and timing issues without sending files to third-party servers.
Music Transcription Prep: Musicians can extract note-level information from recordings as a starting point for creating scores or MIDI arrangements.
Rehearsal Feedback: Teachers can generate visual feedback for pupils showing where notes deviate from intended pitches or rhythms during lessons.
Research & Analysis: Music researchers can use on-device transcriptions to study performance characteristics across takes while preserving data privacy.
