- AI Assistant Access via MCP: Remote MCP server lets Claude, ChatGPT, Codex, Cursor, Grok and OpenClaw read and manage your calendars.
- Agent-Driven Setup: Ask your connected AI agent to create syncs, find free time across calendars and schedule events.
- Per-Calendar Permissions: Grant AI access calendar by calendar, with optional write access and an access log.
- Calendar Sharing: Share a calendar with another person without exposing the underlying account.
- Credit-Based AI Usage: Monthly AI credits cover event searches, availability checks and event edits, with optional top-ups.
- GDPR Compliance: Hosted in Germany with data-protection-focused design.
Best for
- A freelancer mirrors client calendars into one personal calendar while hiding event details behind busy blocks.
- A manager with several roles keeps Outlook, Google and iCloud calendars synchronized to avoid double bookings.
- A tax advisor lets Claude find free slots across work and private calendars and book appointments.
- A coach shares availability with clients without giving access to the full calendar.
- A developer connects Claude Code or Cursor to their calendar through MCP to plan the week.
- An interim manager with multiple companies consolidates every company calendar into a single view.
Orchestria
Orchestria
An AI-powered music production platform offering stem-level orchestration, natural-language conducting, and professional VST rendering.
Key features
- Modular Stem Intelligence: Generates and maintains separate stems (e.g., strings, brass, woodwinds, percussion) as distinct, editable modules so users can modify arrangement, timbre, or dynamics at the stem level without re-rendering entire mixes.
- Natural Language Conduction: Interprets plain-language instructions to modify instrumentation, phrasing, dynamics, and structure (e.g., "make the strings warmer in the chorus"), enabling rapid iteration without manual MIDI editing.
- Professional VST Rendering: Exports or renders generated parts through professional VST chains and instrument emulations, producing high-quality audio ready for DAW import and further processing by engineers.
- Granular Stem Control and Editing: Provides per-stem controls for volume, panning, articulation, and expression, plus the ability to re-generate or swap instrument voicings for individual stems while preserving arrangement context.
- High-Fidelity Generation: Produces realistic orchestral textures with expressive dynamics and articulations tuned for scoring and production use, reducing reliance on manual sample-layering or session players for mockups.
- Export & Workflow Integration: Supports exporting stems, MIDI, and project assets for seamless integration into common DAWs, enabling roundtrip editing and incorporation into existing production pipelines.
- Real-Time Conducting Interface: Enables live or iterative conducting-style adjustments—using text commands or a conduction UI—to steer arrangement and performance characteristics while monitoring immediate rendered results.
- Modular stem intelligence — generate and control individual stems (instruments/tracks) independently
- Natural-language command conduction — direct composition and arrangement via text commands
- Professional VST rendering — render outputs through VSTs for DAW-compatible high-quality audio
- Conductor-oriented workflow — focus on high-level direction rather than low-level production
- Stem export and re-rendering for remixing and post-production
Best for
- Film and TV Scoring Mockups: Rapidly create high-quality orchestral mockups for editors and directors using natural-language directions and export stems for DAW sessions.
- Iterative Composition with Non-Technical Collaborators: Allow non-musician stakeholders to request arrangement or mix changes by plain text (e.g., "make the bridge more dramatic"), speeding feedback cycles.
- Stem-Level Mixing and Mastering Preparation: Generate isolated, high-fidelity stems for each instrument group to hand off to mixing and mastering engineers without manual separation.
- Orchestral Demo Production: Produce polished orchestral demos and proofs-of-concept without hiring session players or constructing complex sample patches.
- DAW Integration and Post-Production: Render parts through VST chains and import into a DAW for additional processing, automation, and final arrangement by producers.
- Collaborative Composition Workflows: Enable composers and arrangers to iterate on orchestrations together by issuing natural language commands and re-rendering targeted stems during review sessions.
- Rapid prototyping of musical ideas and arrangements using natural language prompts
- Integrating AI-generated stems into professional DAW sessions via VST rendering
- Film, TV, and game scoring workflows that need fast iteration on stems and mixes
- Enabling non-producers to direct and arrange music using conversational commands
- Creating stems and isolated parts for remixing, sampling, or collaborative production
