Palmier Pro: The Open-Source AI Video Editor for macOS

Palmier Pro is an open-source video editor for macOS built with Swift to support AI-integrated workflows. It features a built-in MCP server that enables AI agents like Claude and Cursor to collaborate with users directly on the timeline. While the editor is free and open-source, advanced generative AI features require a subscription and Apple Silicon hardware.

Key Points

• Palmier Pro is a Swift-native video editor built from the ground up to integrate AI agents directly into the editing timeline.
• It includes a built-in MCP server that allows external AI tools like Claude and Cursor to interact with and edit the project timeline.
• The core video editor is free and open-source under the GPLv3 license, while generative AI features require a paid subscription.
• The software supports state-of-the-art generative models like Seedance, Kling, and Nano Banana Pro for in-app asset creation.
• It is specifically designed for Apple Silicon hardware and requires macOS 26 (Tahoe) or later.

Sentiment

Positive and curious, with users expressing interest in how AI agents can alleviate the friction of manual video production.

In Agreement

• Manual video editing is often a tedious and unpleasant experience that is ripe for automation.
• The current workflow of downloading AI-generated assets and importing them into a separate editor is inefficient.
• Building natively in Swift provides better performance and fewer dependencies compared to Electron or web-based editors.
• AI is particularly well-suited for 'gruntwork' like rough cuts, transcription-based editing, and beat detection.

Opposed

• The software is currently limited to macOS 26 (Tahoe), excluding Linux and Windows users.
• AI is still not proficient at truly creative editing, as acknowledged by the developers.
• Generative AI features are closed-source and require a backend connection, unlike the core editor.
